Hydroelectric power plant project on the Coulonge River: Report of inquiry and public hearing
International Nuclear Information System (INIS)
1992-01-01
A hydroelectric power plant is proposed for the Coulonge River, a tributary of the Ottawa River in Quebec. Water would be taken from the river through a 609 m tunnel to the plant, which would contain two Francis turbines with a total installed power of 16.2 MW operating under a net head of 43 m and a water flow rate of 21.5 m 3 /s. Other works would be necessary upstream for controlling flow and protecting the intake. Total cost for the two-year construction project is estimated at $28 million and annual revenues are forecast at $6 million. An inquiry and public hearing were held to consider the biophysical, social, economic, and cultural impacts of the proposed hydroelectric project. Results of the hearing are summarized in such areas as legal aspects, environmental quality, water rights, land use, job creation, effects on tourism and recreation, effects on wildlife, water level fluctuations, water quality, and safety. The economic justification for the project is discussed with reference to electricity demand, economic viability, utilization factors, and policies that favor construction of small-scale hydroelectric plants. The project was not found to bring sufficient benefits to the region in which it was to be situated and would not be authorized unless Hydro-Quebec tariff policy with respect to small hydro plants was modified and unless the project sponsor compensates the regional municipality. 13 refs., 11 figs., 4 tabs

2001-01-01
Hydro-Quebec has proposed the development of a hydro-electric power project on the Toulnustouc River, located between Saint-Anne Lake and Manic Reservoir. The work would involve the construction of a power generation plant of 526 MW, construction of a 77 m dam on the Toulnustouc River, 14 km downstream from the existing Lac-Saint-Anne dam, the creation of a new water expanse covering 22 square kilometers, the construction of an embankment, the strengthening of the existing Saint-Anne embankment, digging a 9.8 km gallery, and the construction of a flood spillway. This work would have consequences for three different sectors of the river: between the existing and the proposed dam, between the dam and the projected power plant, and between the power plant and the limit of the influence of the reservoir Manic-2. Hydro-Quebec would like the work to begin in July 2001, with the aim of having the plant in operation in 2005. The overall cost of the project is estimated at 600 million dollars. It is expected that the economic benefits for the region would be in the 211 million dollar range. An environmental assessment of the entire project was performed by Quebec Ministere de l'Environnement. The authors determined that the project was recognized as justified by the Ministere des Ressources Naturelles (Natural Resources Ministry) and concluded that the project was acceptable from an environmental point of view as long as six conditions were met. They touched on the construction of a flood spillway capable of evacuating 19 cubic meters per second at any time during the year, that water be evacuated downstream following a pre-determined debit that varies according to the time of year, monitoring of the brook trout population and its habitat, and environmental monitoring. 46 refs., 7 tabs., 2 figs., 1 annex

2001-01-01
A new hydroelectric project is being proposed on the Peace River in the vicinity of Dunvegan, Alberta, by Glacier Power. The proposal calls for a low head, run-of-the-river hydroelectric power plant which would comprise a powerhouse containing 40 Kaplan turbines, a weir section, two fishways and a boat lock. The capacity of the generating plant would be 80 MW. As per established guidelines, the review process was initiated in July 1999 and is ongoing. Stakeholders, government agencies, both at the federal and provincial levels, are involved in the review process. The potential effects on the ice regime, fish passage and fish mortality and bank stability are the issues that have warranted the most attention to date. Scheduled to begin on October 2, 2001, a public hearing on the project has been arranged by the Alberta Energy and Utilities Board. The objective sought by Glacier Power is to have the project certified as being a green-power plant. Green power is defined as power produced from renewable sources with low environmental impact. The production of power with minimal environmental impacts is being encouraged in Alberta by Glacier Power, which sells power for a premium. 6 refs., 4 figs

Public hearings were held by Quebec's Bureau d'audiences publiques sur l'environnement (BAPE) concerning a proposed hydroelectric development project on the Magpie River in Quebec's Minganie Region. The proposed hydroelectric power plant is to be developed and managed by Hydromega Services Inc. and constructed by Aecon Group Ltd. The project consists of reconstructing a power plant and dam at an existing site that was constructed in 1961 but which has been decommissioned since 1989. The installed capacity of the proposed power plant is 40.6 MW. The drop height for the dam is 21.25 metres. The issues that were addressed during the hearings included the opinions and suggestion of the participants regarding energy provisions, regional development and ecological protection. One of the main concerns facing this project is the loss of spectacular rapids currently used by rafters. The Commission noted that the rapids cannot be saved without significant modification to the design of the project. However, the flooding associated with the project would facilitate fishermen, canoeists and kayakers, thereby preserving the recreational and tourism attributes of the Magpie River. The Commission also noted that the local economic repercussions of the project would benefit the population of the Minganie Region which has a high unemployment rate. Any ecological impacts may be controlled by relevant attenuation measures and follow-up. It was concluded that the proposed project could contribute modestly to meeting the anticipated growth in energy demand in Quebec. refs., figs

The Societe d'energie riviere Sheldrake Inc. (SERS Inc.) is planning to exploit the hydroelectric potential of the Sheldrake River in the Quebec municipality of Riviere au Tonnere. The proposed project will involve building a hydroelectric power station with a maximum capacity of 25 MW on the Sheldrake River, in the Courbe du Sault section. The project will also comprise a dam, a water reservoir and an overflow spillway. The project meets the province's 2006-2015 energy strategy to develop small-scale hydroelectric facilities. The project was subject to an environmental assessment as required by the province of Quebec. This environmental analysis addressed the major challenges facing the hydroelectric development at the Courbe du Sault section of the River, notably the impact on fish habitat, wetlands and the local and regional economic benefits. The environmental assessment did not indicate any habitat destruction for trout or salmon in the forebay. The Quebec Ministry of Sustainable Development, Environment and Parks has deemed the project to be acceptable given that certain conditions are met, including thresholds to stabilize the water level and the construction of a downstream fish passage facility to allow for safe fish migration. 22 refs., 2 tabs., 5 figs., 3 appendices.

The Societe d'Energie Riviere Sheldrake Inc. has proposed the construction of a hydroelectric facility on the Sheldrake River at Riviere-au-Tonnerre in the regional municipality of Minganie in Quebec. The project involves the construction of a headrace canal, intake, tunnel, powerhouse, access roads, electrical transmission line, spillway, weir and a bridge over the Sheldrake River. The proposed development was subject to an environmental evaluation process and public consultation. Quebec's environmental public hearing board held a public hearing on the draft development of the project to hear the concerns and views of the public and stakeholders. The hearing focused on a number issues, such as reasons for the project, its location and socio-economic impacts. The cumulative environmental effects of the project were also examined. The primary concerns were the economic repercussions of the project and its effect on tourism and fish, including salmon. The Board determined that the project would create jobs in a region affected by unemployment and the decay of its municipalities and that it would stimulate the local and regional economy. However, the Board determined that changes to the project are required to minimize impacts on the natural environment. The project proponent must monitor instream flows to ensure that fish passage facilities meet regulations. In addition, since the proposed project crosses 3 bogs, the developer must compensate for lost wetlands. A 10-year follow-up is required to assess the recovery of these environments. The developer must also maintain the aesthetic quality of the Courbe du Sault Falls in order to maintain the eco-tourism in the region. refs., figs.

A coalition of the Oregon wildlife agencies and tribes (the Oregon Wildlife Mitigation Coalition) have forged a cooperative effort to promote wildlife mitigation from losses to Oregon wildlife resources associated with the four mainstream Columbia River and the eight Willamette River Basin hydroelectric projects. This coalition formed a Joint Advisory Committee, made up of technical representatives from all of the tribes and agencies, to develop this report. The goal was to create a list of potential mitigation opportunities by priority, and to attempt to determine the costs of mitigating the wildlife losses. The information and analysis was completed for all projects in Oregon, but was gathered separately for the Lower Columbia and Willamette Basin projects. The coalition developed a procedure to gather information on potential mitigation projects and opportunities. All tribes, agencies and interested parties were contacted in an attempt to evaluate all proposed or potential mitigation. A database was developed and minimum criteria were established for opportunities to be considered. These criteria included the location of the mitigation site within a defined area, as well as other criteria established by the Northwest Power Planning Council. Costs were established for general habitats within the mitigation area, based on estimates from certified appraisers. An analysis of the cost effectiveness of various types of mitigation projects was completed. Estimates of operation and maintenance costs were also developed. The report outlines strategies for gathering mitigation potentials, evaluating them, determining their costs, and attempting to move towards their implementation.

The village of Inukjuak in northern Quebec is not connected to the main electrical grid. This remote village is one of 14 Inuit communities in the Nunavik administrative region where electricity is generated by diesel thermal power plants under the direction of Hydro-Quebec Distribution's Isolated Grid subdivision. The heating of water and buildings is supplied by heavy fuel-oil. A compensation program for the price of fuel-oil is applied in the community. This presentation discussed the need for developing renewable energy sources in order to respond to the energy demands of isolated grids. The community of Inukjuak plans on developing the water resources of the Inukjuak River in order to produce hydroelectricity and reduce the use of diesel fuel. Several possible development sites were identified. The project will contribute to a reduction in energy costs while reducing greenhouse gas emissions. Revenues generated from the power plant will help the village in their economic development by enabling the completion of various community projects. The sustainable development approach taken for the project was discussed and the project's main technical, environmental and social issues were identified. The project is expected to reduce the production of an estimated 8 tons of carbon dioxide emissions by 2011 and nearly 15 tons after 10 years of operation.

Turan, Faiz Mohd; Johan, Kartina
2017-08-01
Sustainably developed and managed hydropower has enormous potential to contribute to global sustainability goals. It is known that hydroelectricity contributing small amounts to greenhouse gas emissions and other atmospheric pollutants. However, developing the remaining hydroelectric potential offers many challenges, and public pressure and expectations on the environmental and social performance of hydroelectric tend to increase over time. This paper aims to develop Systematic Sustainability Assessment (SSA) Tool that promotes and guides more sustainable hydroelectric projects in the context of Malaysia. The proposed SSA tool which not only provide a quality and quantitative report of sustainability performance but also act as Self-Assessment Report (SAR) to provide roadmap to achieve greater level of sustainability in project management for continuous improvement. It is expected to provide a common language that allow government, civil society, financial institutions and the hydroelectric sector to talk about and evaluate sustainability issues. The advantage of SSA tool is it can be used at any stage of hydroelectric development, from the earliest planning stages right through to operation.

The Polyphyto Hydroelectric Project was constructed in 1974 and it has been operating since on the Aliakmonas River, Kozani prefecture, by the Greek Public Power Corporation. The construction of the Ilarion Hydroelectric Project, upstream from the Polyphyto Reservoir, has been recently completed and will start operating in the near future. Apart from hydroelectric power production, the Polyphyto reservoir provides flood control to the areas below the Polyphyto dam. It is also used to manage water provision to the city of Thessaloniki and adjacent agricultural plain, providing at the same time cooling water to the Thermo Electric Projects in Ptolemaida. The Polyphyto reservoir has potential for further development as an economic fulcrum to the region in which is located. The Kozani and Servia-Velvendos Municipalities have proceeded to the construction of several touristic, nautical - athletic and fishing projects. In order to promote such developments, while preserving the artificial wetland, flora and fauna of the Polyphyto Reservoir, it is important to reduce the fluctuation of the reservoir elevation which according to its technical characteristics is 21m. The aim of this paper is to propose the combined operation of the two Hydroelectric Project reservoirs to satisfy all the present Polyphyto Hydroelectric Project functions and to reduce the annual fluctuation of the Polyphyto Reservoir. The HEC-5, Version 8 / 1998 computer model was used in our calculations, as developed by the Hydrologic Engineering Center (HEC) of the US Army Corps of Engineers for reservoir operation simulation. Five possible operation scenarios are tested in this paper to show that the present fluctuation of the Polyphyto Reservoir can be reduced, with some limitations, except during dry weather periods.

Indian areas threatened by hydroelectric projects in Brazil
Energy Technology Data Exchange (ETDEWEB)
Aspelin, P L; Santos, S.C. dos
1981-10-01
In Brazil, as elsewhere, high priority is being given to developing domestic energy sources due to the spectacular increase in the cost of imported petroleum in recent years. This paper discusses the present situation of the thirty-two to thirty-four various Indian areas presently known to be threatened by seven major hydro-electric projects and one flood-control project, either planned or underway, in or directly involving Brazil. A total of at least 100,000 hectares of Indian land (or nearly one hectare for each remaining Brazilian Indian) will be flooded or otherwise expropriated by these projects. Past efforts by the Brazilian National Indian Foundation (FUNAI) to protect the Indians from the pressure of ''national development'' have not been sufficient. Research, planning, publicity, and political pressure are necessary to ensure that their efforts regarding these hydroelectric projects are more successful.

Malheur River Wildlife Mitigation Project, Annual Report 2003.
Energy Technology Data Exchange (ETDEWEB)
Ashley, Paul
2004-01-01
Hydropower development within the Columbia and Snake River Basins has significantly affected riparian, riverine, and adjacent upland habitats and the fish and wildlife species dependent upon them. Hydroelectric dams played a major role in the extinction or major loss of both anadromous and resident salmonid populations and altered instream and adjacent upland habitats, water quality, and riparian/riverine function. Hydroelectric facility construction and inundation directly affected fish and wildlife species and habitats. Secondary and tertiary impacts including road construction, urban development, irrigation, and conversion of native habitats to agriculture, due in part to the availability of irrigation water, continue to affect wildlife and fish populations throughout the Columbia and Snake River Basins. Fluctuating water levels resulting from facility operations have created exposed sand, cobble, and/or rock zones. These zones are generally devoid of vegetation with little opportunity to re-establish riparian plant communities. To address the habitat and wildlife losses, the United States Congress in 1980 passed the Pacific Northwest Electric Power Planning and Conservation Act (Act) (P.L. 96-501), which authorized the states of Idaho, Montana, Oregon, and Washington to create the Northwest Power Planning Council (Council). The Act directed the Council to prepare a program in conjunction with federal, state, and tribal wildlife resource authorities to protect, mitigate, and enhance fish and wildlife species affected by the construction, inundation and operation of hydroelectric dams in the Columbia River Basin (NPPC 2000). Under the Columbia Basin Fish and Wildlife Program (Program), the region's fish and wildlife agencies, tribes, non-government organizations (NGOs), and the public propose fish and wildlife projects that address wildlife and fish losses resulting from dam construction and subsequent inundation. As directed by the Council, project

Instream flow needs below peaking hydroelectric projects
International Nuclear Information System (INIS)
Milhous, R.T.
1991-01-01
This paper reports on a method developed to assist in the determination of instream flow needs below hydroelectric projects operated in a peaking mode. Peaking hydroelectric projects significantly change streamflow over a short period of time; consequently, any instream flow methodology must consider the dual flows associated with peaking projects. The dual flows are the lowest flow and the maximum generation flow of a peaking cycle. The methodology is based on elements of the Physical Habitat Simulation System of the U.S. Fish and Wildlife Service and uses habitat, rather than fish numbers or biomas, as at basic response variable. All aquatic animals are subject to the rapid changes in streamflow which cause rapid swings in habitat quality. Some aquatic organisms are relatively fixed in location in the stream while others can move when flows change. The habitat available from a project operated in peaking mode is considered to be the minimum habitat occurring during a cycle of habitat change. The methodology takes in to consideration that some aquatic animals can move and others cannot move during a peaking cycle

Full Text Available The main feature of a run-off river hydroelectric system is a small size intake pond that overspills when river flow is more than turbines’ intake. As river flow fluctuates, a large proportion of the potential energy is wasted due to the spillages which can occur when turbines are operated manually. Manual operation is often adopted due to unreliability of water level-based controllers at many remote and unmanned run-off river hydropower plants. In order to overcome these issues, this paper proposes a novel method by developing a controller that derives turbine output set points from computed mass flow rate of rivers that feed the hydroelectric system. The computed flow is derived by summation of pond volume difference with numerical integration of both turbine discharge flows and spillages. This approach of estimating river flow allows the use of existing sensors rather than requiring the installation of new ones. All computations, including the numerical integration, have been realized as ladder logics on a programmable logic controller. The implemented controller manages the dynamic changes in the flow rate of the river better than the old point-level based controller, with the aid of a newly installed water level sensor. The computed mass flow rate of the river also allows the controller to straightforwardly determine the number of turbines to be in service with considerations of turbine efficiencies and auxiliary power conservation.

1992-01-01
The draft guidelines on the preparation of Hydro-Quebec's environmental and social impact statement for the proposed Great Whale River hydroelectric project are detailed. The guidelines cover project justification, description of the biophysical and social environments, project description, impacts of the project, mitigative measures, residual impacts and compensatory measures, environmental monitoring and follow-up programs. The proponent is asked to provide the justification for the project, including its general rationale, and to evaluate the long-term impact of the project. In justifying the project, the proponent should present energy demand and supply scenarios in sufficient detail to demonstrate the need for the project within the context of sustainable development. Long term impacts on the ecosystems of James Bay and Hudson Bay must be examined, as well as broad ecosystemic impacts such as those on the boreal forest, the tundra, as well as such considerations as global warming and changes in biological and cultural diversity

Hoopa Valley Small Scale Hydroelectric Feasibility Project
Energy Technology Data Exchange (ETDEWEB)
Curtis Miller
2009-03-22
This study considered assessing the feasibility of developing small scale hydro-electric power from seven major tributaries within the Hoopa Valley Indian Reservation of Northern California (http://www.hoopa-nsn.gov/). This study pursued the assessment of seven major tributaries of the Reservation that flow into the Trinity River. The feasibility of hydropower on the Hoopa Valley Indian Reservation has real potential for development and many alternative options for project locations, designs, operations and financing. In order to realize this opportunity further will require at least 2-3 years of intense data collection focusing on stream flow measurements at multiple locations in order to quantify real power potential. This also includes on the ground stream gradient surveys, road access planning and grid connectivity to PG&E for sale of electricity. Imperative to this effort is the need for negotiations between the Hoopa Tribal Council and PG&E to take place in order to finalize the power rate the Tribe will receive through any wholesale agreement that utilizes the alternative energy generated on the Reservation.

Battle looms over hydroelectric dam relicensing
International Nuclear Information System (INIS)
Simpson, J.
1993-01-01
Environmental groups, buoyed by support from influential lawmakers, are vowing to change the Federal Energy Regulatory Commission's (FERC's) hydroelectric relicensing procedures. For too long, the groups say, the hydroelectric industry has benefitted from a cozy relationship with the FERC, which has emphasized economic over environmental considerations. The success or failure of the environmentalists agenda will likely prove critical to the hydroelectric industry. With 237 hydroelectric licenses up for renewal this year - the most ever considered by the FERC in one year - and four vacant seats at the Commission, FERC hydro policy appears poised for upheaval. The groups have proposed a multipoint program to address perceived shortcomings in the FERC's hydroelectric relicensing procedures. The program includes recommendations to: Shorten dam licenses (which currently stretch 30 to 50 years) and require the FERC to periodically reevaluate the terms of hydropower licenses; Increase Congressional oversight of the FERC to assure adherence to environmental laws, including the National Environmental Policy Act, which mandates the preparation of environmental impact statements where appropriate; Mandate facilities for upstream and downstream fish passage; Establish a mitigation fund, collectable from dam owners, for river conservation and restoration programs; Promote all alternatives to relicensing projects, including denial of project licenses; and Reassign the FERC's hydropower jurisdiction to another federal agency, such as the Environmental Protection Agency or the Department of the Interior

In the Amazon Basin, naturally occurring methylmercury bioaccumulates in fish, which is a key source of protein consumed by riverine populations. The hydroelectric power-plant project at Santo Antônio Falls allows us to compare the Hg exposure of riverine populations sparsely distributed on both sides of the Madeira river before the area is to be flooded. From 2009 to 2011, we concluded a population survey of the area (N = 2,008; representing circa 80% of community residents) that estimated fish consumption and mercury exposure of riverine populations with different degrees of lifestyle related to fish consumption. Fish samples from the Madeira river (N = 1,615) and 110 species were analyzed for Hg. Hair-Hg was significantly lower (p < 0.001) in less isolated communities near to the capital of Porto Velho (median 2.32 ppm) than in subsistence communities in the Cuniã Lake, 180 km from Porto Velho city (median 6.3 ppm). Fish Hg concentrations ranged from 0.01 to 6.06 µg/g, depending on fish size and feeding behavior. Currently available fish in the Madeira river show a wide variability in Hg concentrations. Despite cultural similarities, riparians showed hair-Hg distribution patterns that reflect changes in fish-eating habits driven by subsistence characteristics.

This study examines envirorunental mitigation practices that provide upstream and downstream fish passage and protection at hydroelectric projects. The study includes a survey of fish passage and protection mitigation practices at 1,825 hydroelectric plants regulated by the Federal Energy Regulatory Commission (FERC) to determine frequencies of occurrence, temporal trends, and regional practices based on FERC regions. The study also describes, in general terms, the fish passage/protection mitigation costs at 50 non-Federal hydroelectric projects. Sixteen case studies are used to examine in detail the benefits and costs of fish passage and protection. The 16 case studies include 15 FERC licensed or exempted hydroelectric projects and one Federally-owned and-operated hydroelectric project. The 16 hydroelectric projects are located in 12 states and range in capacity from 400 kilowatts to 840 megawatts. The fish passage and protection mitigation methods at the case studies include fish ladders and lifts, an Eicher screen, spill flows, airburst-cleaned inclined and cylindrical wedgewire screens, vertical barrier screens, and submerged traveling screens. The costs, benefits, monitoring methods, and operating characteristics of these and other mitigation methods used at the 16 case studies are examined.

The technical and economic feasibility of low head hydroelectric power development at existing sites along the Mousam River in southeastern Maine was studied. The following areas were investigated: determination of available energy; development of restoration concepts; environmental studies; historical and archeological studies; assessment of civil construction requirements; geotechnical and geologic assessment of existing dams; assessment of turbine alternatives; assessment of generator and utility interface alternatives; economic analysis; and restoration concept evaluation and selection. The results of the hydropower evaluation showed that: of the seven sites evaluated, only four can be considered economically feasible for refurbishment at this time; the use of used and/or rebuilt equipment is more economically attractive than new equipment; the cost of equipment at each site was of the same order as the cost of the dam reconstruction; and the cost of fuel prices will be the determining feature of whether the sites should be reconstructed.

Environmental evaluation of Turkey's transboundary rivers' hydropower systems
International Nuclear Information System (INIS)
Berkun, M.
2010-01-01
The hydroelectric power and potential environmental impacts of hydroelectric projects in 2 transboundary rivers in Turkey were assessed. The southeastern Anatolia project (GAP) is expected to encompass 27 dams and 19 hydroelectric power plants. The large-scale project will increase domestic electricity production and help to provide irrigation for large agricultural schemes. The Coruh project will consist of 27 dams and hydroelectric power plants, which are expected to have serious environmental impacts in both upstream Turkey and downstream Georgia. A slowing down of each river's velocity will cause changes in sediment transport, while the storage of water in large reservoirs will alter water quality and cause changes in local micro-climates. Irrigation methods may cause soil erosion and salinization. The construction of 2 GAP dams on the Tigris and Euphrates rivers has caused protest from Syria and Iraq. Economic development in the regions caused by the proposed hydroelectric projects is expected to have significant environmental impacts on woodland and grassland areas. The projects are expected to adversely affect threatened plant, mammal, and fish species. More detailed cumulative impact and environmental impact assessments are needed to evaluate the economic, environmental, and social problems that are likely to arise as a result of the projects. 17 refs., 3 tabs., 6 figs.

This paper is based on a study conducted for the World Bank which evaluated the feasibility of developing an empirically based ex ante project analysis system for hydroelectric projects. The system would be used to assess: the reasonableness of engineering-based cost and schedule estimates used for project appraisal and preliminary estimates used to select projects for appraisal; and the potential for cost growth and schedule slip. The system would help identify projects early in the project appraisal process that harbor significantly higher than normal risks of overrunning cost and schedule estimates

Hornig, J.F.
1999-01-01
The book, which is an analysis and not an advocacy, examines the anatomy of the controversy that has swirled around the James Bay project - the La Grande and Great Whale projects combined - from the 1970s to the 1990s, and seeks, in the process, to determine whether there are lessons that can be learned from such an analysis that are applicable to other cases as well as to James Bay itself. The contributors are interested, at one and the same time, in finding ways to integrate the knowledge of natural scientists and social scientists to deepen the understanding of human/environment relations and to link science and policy to encourage a productive dialogue between practitioners and scholars in this increasingly important area of inquiry. The contributor's papers include the following: introduction to the issues; hydroelectric power development at James Bay: establishing a frame of reference; James Bay: environmental considerations for building large hydroelectric dams and reservoirs in Quebec; elevated mercury in fish as a result of the James Bay hydroelectric power development: perception and reality; the Cree people of James Bay: assessing the social impacts of hydroelectric dams and reservoirs; culture, social change, and Cree opposition to the James Bay hydroelectric development; and the impact of James Bay hydroelectric development on the art and craft of the James Bay Cree. The authors of the volume have attempted to stand back and examine just a few of these issues from the perspective of a variety of disciplines, and their purpose is to inform and stimulate thoughtful consideration by providing an overall perspective that might might serve to broaden the context in which specific issues can be debated. refs., 3 tabs., 5 figs

Hydroelectric project EA's [environmental assessments]: The Magpie development in northern Ontario
International Nuclear Information System (INIS)
Ashwood, K.
1992-01-01
Great Lakes Power recently constructed a hydroelectric plant on the Magpie River near Wawa, Ontario. The project involved three main elements: construction of a 33 m high dam, a 15.5 MW power station, and a spillway at Steephill Falls; construction of a 3.5 m high overflow weir just above the crest of scenic Magpie Falls, creating a head pond to supply a 15 MW power plant; and construction of a weir and 15 MW power plant at Mission Falls. Although this was a private development and therefore not automatically subject to Ontario's Environmental Assessment Act, Great Lakes Power decided to conform with the act's requirements and undertook a comprehensive environmental assessment (EA). Environmental issues were focused on changes in hydrology and water quality, impacts on fisheries and natural resources, slope stability and erosion, socioeconomic impacts, impacts on heritage resources, and impacts on tourism and recreation. The project was approved subject to conditions which included implementation of mitigation and monitoring requirements outlined in the EA document. Environmental specialists worked closely with the engineers at the detailed design stage of the project, resulting in modifications to the preliminary design to minimize environmental impacts

Labelle, M.; Robitaille, F. [Hydro-Quebec, Montreal, PQ (Canada)
1995-12-31
Construction of the Lake Robertson hydroelectric project on Quebec`s Lower North Shore was discussed in detail. The dam and powerhouse, located on the HaHa River, consists of a 134 m long concrete gravity dam, and a 21 MW powerhouse with two 69 kV transmission lines and four substations. The climate, terrain, and geography of the region, all of them characterized as severe, and the logistics of construction of the dam and power lines, aggravated by the isolation and severe conditions at the site, were described. The roller compacted concrete design and construction were noted, and justification for a concrete dam over an earth-fill dam was provided. Economics, properties, and composition of the roller compacted concrete (RCC) were examined, and control test results for the RCC concrete were provided. The use of RCC for the Lake Robertson development was described as successful in terms of the quality, watertightness, and completion time. The experience gained by the participants will make it possible to offer RCC as an alternative on various other projects. 2 figs.

Newfoundland and Labrador Hydro has proposed to develop the hydroelectric potential of the lower Churchill River by constructing generating facilities at Gull Island and Muskrat Falls. This paper presented the results of a study that was conducted to collect baseline data on greenhouse gas (GHG) fluxes/emissions of carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O) from the lower Churchill River, Smallwood reservoir, and natural lakes in the upper and lower Churchill regions. The purpose of the study was to compare GHG fluxes between the lower Churchill River, Smallwood reservoir and those of the nearby natural lakes and to compare GHG fluxes between the Smallwood reservoir and those of boreal reservoirs in northern Quebec. The paper provided a description of the site and the methodology for GHG flux measurement. The results and discussion focused on physical-chemical variables and GHG fluxes. The study results were to be used in the environmental assessment of the project. It was concluded that the lower Churchill River has higher CO 2 fluxes and lower CH 4 fluxes than the Smallwood reservoir and higher CO 2 fluxes than natural lakes in the region. There was no significant difference in N 2 O fluxes between the sampled waterbodies. Both CO 2 and CH 4 fluxes from the lower Churchill River were comparable to other Canadian reservoirs. 12 refs., 2 tabs., 6 figs

Emissions from hydroelectric reservoirs and comparison of hydroelectricity, natural gas and oil
International Nuclear Information System (INIS)
Gagnon, L.; Chamberland, A.
1993-01-01
When reservoirs are created, a small fraction of the flooded organic matter decomposes into humic acids, carbon dioxide (CO 2 ), methane (CH 4 ), nitrogen, phosphorus, and other elements. The major greenhouse gases produced are CO 2 and CH 4 . For northern projects, Canadian studies on emissions from hydroelectric reservoirs have reached similar conclusions: Emissions, including methane, are less than 35 kg CO 2 equivalent per MWh. Using a typical project in northern Quebec as the basis for analysis, none of the studies dispute the considerable advantages of hydroelectricity regarding greenhouse gas emissions. Taking into account all components of energy systems, emissions of greenhouse gases from natural-gas power plants are 24 to 26 times greater than emissions from hydroelectric plants. The Freshwater Institute, in an article published in Ambio suggests that emissions from hydroelectric plants could be a significant source of greenhouse gases. This conclusion does not apply to most hydroelectric projects for two reasons: First, the Freshwater Institute's studies concerned flooded peatlands and shallow reservoirs that are not typical of most hydro projects; and second, the Institute analyzed a hydro project with a ratio of flooded area to energy production that is 6 to 10 times higher than typical projects in Canada. 7 refs, 4 tabs

Illustrated by photos, maps, figures and graphs, this Power Point presentation outlines the important remaining potential of hydroelectricity in France: 10.6 TWh. It indicates how this potential has been assessed and calculated. Even if possibilities exist everywhere (either by building new dams or by exploiting existing weirs), four regions present a higher potential for new works: Rhone-Alpes, Midi-Pyrenees, Auvergne, and Provence-Alpes-Cote d'Azur. Maps indicate the concerned rivers and locations in some regions. Such projects which could boost economic local, regional and national development must be designed while taking planning tools into account (notably the climate-air-energy regional schemes), and rules related to river preservation

To date, little is known about the water quality downstream of the largest dam in Malaysia, the Bakun hydroelectric dam. Therefore, the objective of the study was to determine the water quality downstream of the dam when the spillway was closed and when it was opened. Results of the study indicate that the dam plays a significant role in regulating the water quality downstream of it. When the spillway was closed, pH and oxygen were lower in the river where DO was below 5 mg/L. When the spillway was opened, the water quality improved in terms of oxygen content (>8.0 mg/L, total sulphide (TS, and chemical oxygen demand (COD but deteriorated in terms of five-day biochemical oxygen demand (BOD5, total ammonia nitrogen (TAN, and total phosphorus (TP. Additionally, the intensity of the impacts, particularly BOD5, COD, and TAN, shows a declining trend as distance from the dam increases. This study shows that impacts on the water quality extend to a distance of 32 km from the dam particularly turbidity and DO and opening the spillway changes the water quality significantly.

The Labrador Innu have expressed their concerns regarding the proposed development of a huge hydroelectric project for the Nitassinan Rivers. The Innu people were not consulted regarding the negotiations which will take place between Newfoundland and Quebec. The biggest concern of the Innu people is the cumulative environmental and social effects of the proposed development and how it will contribute to opening up their territory to further development. For example, access roads, transmission corridors and large-scale clear-cut forestry operations would all impact on their traditional way of life. This paper also described the impacts that the Innu have already experienced as a result of hydroelectric development on the Nitassinan Rivers during the 1970s, when the government of Newfoundland gave the rights to develop and exploit water resources, forests and minerals to a private company. At that time, large areas of hunting and trapping territories were flooded, belongings were lost and burial sites were flooded. The flooding also resulted in increased levels of methyl mercury in fish in the reservoirs as well as downstream. The losses suffered by the Innu people have yet to be addressed by the governments

Hydroelectricity will continue to be important for meeting power requirements in developing countries. Much of the funding required for hydroelectric projects must come from non-government source; hydroelectric projects will therefore need to be attractive to private investors. This note explores the risks investors face, how this can be mitigated, and how the World Bank group can offer advice (as well as finance) to member countries to facilitate investment in hydro electric projects. 3 refs., 1 fig

This report presents the results of an environmental assessment of Hydro-Quebec's proposed project to build a new facility on the Peribonka River. The facility includes a run-of-river generating station with an installed capacity of 385 MW. The Quebec Region of the Department of Fisheries and Oceans Canada has conducted an environmental assessment of the project's effects. A summary of the project and the environment in which it will be carried out was presented along with the results of public consultations conducted by Hydro-Quebec. A summary of the main environmental effects was included along with cumulative effects and the effects caused by accidents or malfunctions that may occur. In addition, the terms and conditions of mitigation measures and follow-up programs were described and the significance of any environmental impacts were assessed. The project includes the construction of a 80 metre high dam, two dikes and one spillway upstream of the mouth of the Manouane River. The level of the reservoir would remain at close to its maximum level of 244.2 metres to optimize hydroelectric production. The power house would be integrated into the Hydro-Quebec transmission network. The main impacts of the project would result from the construction of the reservoir, the encroachment caused by associated facilities and the changes in hydrological conditions. This report outlined the current use of lands and resources for traditional purposes by Aboriginals. It also discussed the effects of natural events such as flooding, waves and climate that may cause damage to the facilities. It was determined that the project is not likely to cause significant effects on the renewable resources of the forest and the fisheries. The Department of Fisheries and Oceans, after having taking into account proposed mitigation measures, has rendered a preliminary conclusion which states that the project is not likely to have significant negative environmental effects. 29 refs., 7 tabs., 2

The Libby hydroelectric project, located on the Kootenai River in northwestern Montana, resulted in several impacts to the wildlife communities which occupied the habitats inundated by Lake Koocanusa. Montana Department of Fish, Wildlife and Parks, in cooperation with the other management agencies, developed an impact assessment and a wildlife and wildlife habitat mitigation plan for the Libby hydroelectric facility. In response to the mitigation plan, Bonneville Power Administration funded a cooperative project between the Kootenai National Forest and Montana Department of Fish, Wildlife and Parks to develop a long-term habitat enhancement plan for the bighorn sheep and mule deer winter and spring ranges adjacent to Lake Koocanusa. The project goal is to rehabilitate 3372 acres of bighorn sheep and 16,321 acres of mule deer winter and spring ranges on Kootenai National Forest lands adjacent to Lake Koocanusa and to monitor and evaluate the effects of implementing this habitat enhancement work. 2 refs.

The BAKUN Hydroelectric Power Project in Malaysia represents, alongside the Three Gorges Project in China, one of today's most closely observed hydropower projects. The Bakun Project features a generating capacity of 2 520 MW, a 205 m high concrete face rockfill dam and a 1 320 km long power transmission system from Sarawak (Borneo) to West Malaysia. Implementation costs are estimated at around DM 10 000 million. In December 1996 the concession to construct and operate the Bakun Project for a period of 30 years on a BOT (build-operate-transfer) basis was granted to the Bakun Hydro-Electric Corporation, a private project development company. A US-Dollar million contract was awarded one year prior to this concession, to construct the river diversion works in advance. Completion of the three concrete-lined diversion tunnels, each with an inner diameter of 12 m, is scheduled for the end of 1998. After a brief overview of the Bakun Project, the paper describes a typical structure of the parties involved and the legal framework for BOT project finance. The most important features of the concession agreement, the power purchase agreement (PPA) and the engineering, procurement and construction (EPC) contract are explained. Finally, the paper emphasizes that in future the water resources engineer will have to be more involved with topics such as fixed-price contracts, risk management, turnkey solutions and project finance.

On our river territories, the development of renewable energy and the restoration of the quality of the aquatic ecosystems both illustrate the need to reconcile the different usages of water resources while still guaranteeing proper functioning of the ecosystems. Hydroelectricity is the crux of the problem. Because of its mountainous hydrographic network and its favourable hydrology, the Adour-Garonne basin witnessed large-scale development of its hydroelectric potential throughout the 20. century. Approaching the question of hydroelectricity from the point of view of the river territories puts all the challenges facing them into their true perspective. Two distinct examples in the Adour-Garonne basin illustrate the partnership between the Water Agency and the local authorities in the Garonne and Dordogne basins: on the Garonne River, reconciling water usages with the maintenance of adequate water levels at times of drought; on the Dordogne River, reducing the impact of the hydro-peaking.

Operation of the hydroelectric projects including relatively important water reservoirs provides implicitly side effects favorable to water management (increase of minimum provided flows, flood routing, etc) and to related fields (additional facilities for water supply, extension of the public utility networks as: road, telecommunication, electric lines, favoring the tourism and recreative activities). The paper suggests methodologies for economic and financial assessment of these effects, the turning to account of which, may increase the efficiency of the hydroelectric development and may stimulate the interest for new investments in the field.(author). 3 figs., 5 refs

A summary is presented of discussions and conclusions at a workshop held to examine the potential effects of hydroelectric development on beluga whales of the Nelson River estuary in Manitoba. Background information is provided on the estuary, beluga whales and their use of arctic and subarctic estuaries, and hydroelectric development on the Nelson River. Potential impacts of such development on the whales are reviewed in the categories of direct effects of changes in physical-chemical conditions (temperature and discharge), indirect effects of disturbances mediated through the food chain, and effects on socioeconomic conditions that may affect beluga whales. Since the biology of beluga whales and other phenomena of interest in this study are poorly known, recommendations are made for research and monitoring activities in the Nelson River estuary. In general, the workshop participants felt that changes in the estuary due to hydroelectric development would not be large enough to affect beluga whales strongly. 34 refs., 1 fig

In February 2017, the Grand River Dam Authority filed to relicense the Pensacola Hydroelectric Project with the Federal Energy Regulatory Commission. The predominant feature of the Pensacola Hydroelectric Project is Pensacola Dam, which impounds Grand Lake O’ the Cherokees (locally called Grand Lake) in northeastern Oklahoma. Identification of information gaps and assessment of project effects on stakeholders are central aspects of the Federal Energy Regulatory Commission relicensing process. Some upstream stakeholders have expressed concerns about the dynamics of sedimentation and flood flows in the transition zone between major rivers and Grand Lake O’ the Cherokees. To relicense the Pensacola Hydroelectric Project with the Federal Energy Regulatory Commission, the hydraulic models for these rivers require high-resolution bathymetric data along the river channels. In support of the Federal Energy Regulatory Commission relicensing process, the U.S. Geological Survey, in cooperation with the Grand River Dam Authority, performed bathymetric surveys of (1) the Neosho River from the Oklahoma border to the U.S. Highway 60 bridge at Twin Bridges State Park, (2) the Spring River from the Oklahoma border to the U.S. Highway 60 bridge at Twin Bridges State Park, and (3) the Elk River from Noel, Missouri, to the Oklahoma State Highway 10 bridge near Grove, Oklahoma. The Neosho River and Spring River bathymetric surveys were performed from October 26 to December 14, 2016; the Elk River bathymetric survey was performed from February 27 to March 21, 2017. Only areas inundated during those periods were surveyed.The bathymetric surveys covered a total distance of about 76 river miles and a total area of about 5 square miles. Greater than 1.4 million bathymetric-survey data points were used in the computation and interpolation of bathymetric-survey digital elevation models and derived contours at 1-foot (ft) intervals.

The aim of this paper is to discuss the modality of project finance of financing of enterprises, which is the main modality of structuring of hydroelectric projects in Brazil. In the discussion will be highlighted the importance of contracts EPC (Engineering, Search and Construction) in the structuring of project finances. This financing model has particular characteristics related to risk sharing and financial flexibility that enable the financing of projects with long-term capital, however, due to participation of various actors and the nature of the structure of project finance, the negotiation and drafting of contracts are always very complex.

1979-02-22
The feasibility of generating additional hydroelectric power from five consecutive existing dams located on the Boardman River in Grand Traverse County and Traverse City, Michigan, was investigated. The potential hydropower production capabilities, in terms of base load power and peak load power, the legal-institutional-environmental constraints, and the economic feasibility, including capital investment, operating costs and maintenance costs, were evaluated for each of the five dam sites individually and as a series of co-dependent facilities. The impact of installing fish passages at each site was analyzed separately. The feasibility assessment utilized the present worth analytical method, considering revenue based on thirty mills/kWh for power, 0.4% general economy escalation rate, and a 6% net income to the municipal utility. The sensitivity of fuel costs increasing at a different rate than the general price-escalation was tested by allowing the increase in fuel costs to vary from 3 to 8% per year. Assuming fuel costs increase at the same rate as the general economy, it is feasible to update, retrofit, renovate, and install hydroelectric generating capacity at Sabin, Boardman and Brown Bridge. Rehabilitation of Union Street and Keystone is also feasible but somewhat less attractive. Operating the dams as a co-dependent system has environmental advantages and can provide additional revenue through peak load power rates. A development plan to implement the above is outlined utilizing an ownership arrangement whereby Grand Traverse County provides easements for Sabin and Boardman Dams. The plan calls for operation of the system by Traverse City.

Final Technical Report - Modernization of the Boulder Canyon Hydroelectric Project

The Boulder Canyon Hydroelectric Project (BCH) was purchased by the City of Boulder, CO (the city) in 2001. Project facilities were originally constructed in 1910 and upgraded in the 1930s and 1940s. By 2009, the two 10 MW turbine/generators had reached or were nearing the end of their useful lives. One generator had grounded out and was beyond repair, reducing plant capacity to 10 MW. The remaining 10 MW unit was expected to fail at any time. When the BCH power plant was originally constructed, a sizeable water supply was available for the sole purpose of hydroelectric power generation. Between 1950 and 2001, that water supply had gradually been converted to municipal water supply by the city. By 2001, the water available for hydroelectric power generation at BCH could not support even one 10 MW unit. Boulder lacked the financial resources to modernize the facilities, and Boulder anticipated that when the single, operational historical unit failed, the project would cease operation. In 2009, the City of Boulder applied for and received a U.S. Department of Energy (DOE) grant for $1.18 million toward a total estimated project cost of $5.155 million to modernize BCH. The federal funding allowed Boulder to move forward with plant modifications that would ensure BCH would continue operation. Federal funding was made available through the American Recovery and Reinvestment Act (ARRA) of 2009. Boulder determined that a single 5 MW turbine/generator would be the most appropriate capacity, given the reduced water supply to the plant. Average annual BCH generation with the old 10 MW unit had been about 8,500 MW-hr, whereas annual generation with a new, efficient turbine could average 11,000 to 12,000 MW-hr. The incremental change in annual generation represents a 30% increase in generation over pre-project conditions. The old turbine/generator was a single nozzle Pelton turbine with a 5-to-1 flow turndown and a maximum turbine/generator efficiency of 82%. The new unit is a

This report discusses the possible environmental consequences of a planned hydroelectric power development of the river Grunnaai, Norway. The consequences are found to be small, provided the proper counter measures are taken. Without counter measures, there may be moderate consequences on fish populations and botanical conditions, directly dependent on the changed water flow. The greatest value of the area concerned lies in its unspoiled wilderness character. There are extensive lists of birds and mammals and plant species registered in the river valley. 51 refs., 7 figs., 4 tabs

Fisheries studies on the lower Nelson River (Manitoba) system have had the goals of gaining an understanding of the fisheries resources present, assessing current and potential impacts of hydroelectric developments, and investigating enhancement or mitigative options. In 1988, a resource inventory of McMillan and 12-Mile Creeks was conducted to increase understanding of brook trout stocks in the Limestone River system. Results indicate that both streams contain self-sustaining populations. Baseline data collection in the Conawapa Forebay of the Nelson River was initiated in 1988. Inventories of fish populations were conducted, focusing on lake sturgeon. Three long-term monitoring projects were continued in 1988, investigating the populations of spawning brook trout, larval brook trout, and anadromy in brook trout. Four major tributaries to the Nelson River were classified on the basis of physical and chemical characteristics in an attempt to understand brook trout distribution patterns. Ten sturgeon were captured in Angling Lake in 1988 and fitted with radio tags to assess the importance of the Angling Lake-Angling River system to Nelson River lake sturgeon. To investigate the feasibility of enhancing brook trout populations in the Nelson River system, baskets of eggs were planted in previously identified spawning areas in three creeks in 1988. The eggs developed and hatched only in CN Creek. The potential for rehabilitating the Kettle River brook trout population by transfer of fish from other rivers was also investigated in 1988. Radio-tagged fish remained in the Kettle River-Long Spruce system throughout the life of the tags and appear to have found suitable summer and winter habitat. 60 refs., 76 figs., 38 tabs

Although fisheries biology studies are frequently performed at US Army Corps of Engineers (USACE) projects along the Columbia and Snake Rivers, there is currently no consistent definition of the ``forebay'' and ``tailrace'' regions for these studies. At this time, each study may use somewhat arbitrary lines (e.g., the Boat Restriction Zone) to define the upstream and downstream limits of the study, which may be significantly different at each project. Fisheries researchers are interested in establishing a consistent definition of project forebay and tailrace regions for the hydroelectric projects on the lower Columbia and Snake rivers. The Hydraulic Extent of a project was defined by USACE (Brad Eppard, USACE-CENWP) as follows: The river reach directly upstream (forebay) and downstream (tailrace) of a project that is influenced by the normal range of dam operations. Outside this reach, for a particular river discharge, changes in dam operations cannot be detected by hydraulic measurement. The purpose of this study was to, in consultation with USACE and regional representatives, develop and apply a consistent set of criteria for determining the hydraulic extent of each of the projects in the lower Columbia and Snake rivers. A 2D depth-averaged river model, MASS2, was applied to the Snake and Columbia Rivers. New computational meshes were developed most reaches and the underlying bathymetric data updated to the most current survey data. The computational meshes resolved each spillway bay and turbine unit at each project and extended from project to project. MASS2 was run for a range of total river flows and each flow for a range of project operations at each project. The modeled flow was analyzed to determine the range of velocity magnitude differences and the range of flow direction differences at each location in the computational mesh for each total river flow. Maps of the differences in flow direction and velocity magnitude were created. USACE

The lower Sg. Piah hydro-electric station is a river run-off hydro scheme with generators capable of generating 55MW of electricity. It is located 30km away from Sg. Siput, a small town in the state of Perak, Malaysia. The station has two turbines (Pelton) to harness energy from water that flow through a 7km tunnel from a small intake dam. The trait of a run-off river hydro station is small-reservoir that cannot store water for a long duration; therefore potential energy carried by the spillage will be wasted if the dam level is not appropriately regulated. To improve the station annual energy output, a new controller based on the computed river flow has been installed. The controller regulates the dam level with an algorithm based on the river flow derived indirectly from the intake-dam water level and other plant parameters. The controller has been able to maintain the dam at optimum water level and regulate the turbines to maximize the total generation output.

On January 27, 2010 the City of North Little Rock, Arkansas received notification of the awarding of a Department of Energy (DOE) grant totaling $450,000 in funding from the American Recovery and Reinvestment Act (ARRA) under the Project Title: Recovery Act: Hydroelectric Facility Improvement Project – Automated Intake Clearing Equipment and Materials Management. The purpose of the grant was for improvements to be made at the City’s hydroelectric generating facility located on the Arkansas River. Improvements were to be made through the installation of an intake maintenance device (IMD) and the purchase of a large capacity wood grinder. The wood grinder was purchased in order to receive the tree limbs, tree trunks, and other organic debris that collects at the intake of the plant during high flow. The wood grinder eliminates the periodic burning of the waste material that is cleared from the intake and reduces any additional air pollution to the area. The resulting organic mulch has been made available to the public at no charge. Design discussion and planning began immediately and the wood grinder was purchased in July of 2010 and immediately put to work mulching debris that was gathered regularly from the intake of the facility. The mulch is currently available to the public for free. A large majority of the design process was spent in discussion with the Corps of Engineers to obtain approval for drawings, documents, and permits that were required in order to make changes to the structure of the powerhouse. In April of 2011, the City’s Project Engineer, who had overseen the application, resigned and left the City’s employ. A new Systems Mechanical Engineer was hired and tasked with overseeing the project. The transfer of responsibility led to a re-examination of the original assumptions and research upon which the grant proposal was based. At that point, the project went under review and a trip was booked for July 2011 to visit facilities that currently

From Skopje to Gevgelia, an annual quantity of 4,5 billions M 3 of water flows out of the territory through the Vardar River for only 60 hours. This poses two questions. The first is whether the flowing out of the water can be decelerated, i.e., whether the water can be kept for at least 60 days and the second question is how this can be realized. Construction of 12 hydroelectric power plants is envisaged along Vardar River, i.e., its section extending from Skopje to the border on Greece, which means within a length of 200 km. Two of these are classical hydroelectric power plants (HPP 'Veles' and HPP 'Gradec'), while the remaining 10 hydroelectric power plants are distributed in a cascade along the river course, with small water head of H = 8,20 - 8,50 m and are considered ecological hydroelectric power plants according to European criteria. For us, these represent a new technology of design and construction particularly considering the part referring to the equipment, while in Europe, there is assembly-line production of such equipment. Presented very briefly in the paper shall be the main technical information on these hydroelectric power plants, namely HPP Kukuricani, as a pilot project to be realized by AD ESM. (Author)

Hydroelectric dams impact the downstream migrations of silver American Eels Anguilla rostrata via migratory delays and turbine mortality. A radiotelemetry study of American Eels was conducted to determine the impacts of five run-of-the-river hydroelectric dams located over a 195-km stretch of the Shenandoah River, Virginia–West Virginia, during fall 2007–summer 2010. Overall, 96 radio-tagged individuals (mean TL = 85.4 cm) migrated downstream past at least one dam during the study. Most American Eels passed dams relatively quickly; over half (57.9%) of the dam passage events occurred within 1 h of reaching a dam, and most (81.3%) occurred within 24 h of reaching the dam. Two-thirds of the dam passage events occurred via spill, and the remaining passage events were through turbines. Migratory delays at dams were shorter and American Eels were more likely to pass via spill over the dam during periods of high river discharge than during low river discharge. The extent of delay in migration did not differ between the passage routes (spill versus turbine). Twenty-eight American Eels suffered turbine-related mortality, which occurred at all five dams. Mortality rates for eels passing through turbines ranged from 15.8% to 40.7% at individual dams. Overall project-specific mortality rates (with all passage routes combined) ranged from 3.0% to 14.3%. To protect downstream-migrating American Eels, nighttime turbine shutdowns (1800–0600 hours) were implemented during September 15–December 15. Fifty percent of all downstream passage events in the study occurred during the turbine shutdown period. Implementation of the seasonal turbine shutdown period reduced cumulative mortality from 63.3% to 37.3% for American Eels passing all five dams. Modifying the turbine shutdown period to encompass more dates in the spring and linking the shutdowns to environmental conditions could provide greater protection to downstream-migrating American Eels.

The aim of this paper is to discuss the modality of project finance of financing of enterprises, which is the main modality of structuring of hydroelectric projects in Brazil. In the discussion will be highlighted the importance of contracts EPC (Engineering, Search and Construction) in the structuring of project finances. This financing model has particular characteristics related to risk sharing and financial flexibility that enable the financing of projects with long-term capital, however, due to participation of various actors and the nature of the structure of project finance, the negotiation and drafting of contracts are always very complex.

Hydroelectric developments can result in a number of negative environmental consequences. Conservation aquaculture is a branch of science derived from conservation and population recovery studies on endangered fishes. Here we discuss the impacts on fishes caused by hydropower projects in Lixianjiang, and evaluate effects and problems on the propagation of Parazacco spilurus, Hemibagrus pluriradiatus, Neolissochilus benasi and Semilabeo obscurus. A successful propagation project includes foraging ecology in fields, pond cultivation, juvenile fish raising, prevention and curing on fish disease, genetic management, artificial releasing and population monitoring. Artificial propagation is the practicable act on genetic intercommunication, preventing population deterioration for fishes in upper and lower reaches of the dam. For long-term planning, fish stocks are not suitable for many kind of fishes, but can prevent fishes from going extinct in the wild. Basic data collection on fish ecology, parent fish hunting, prevention on fish disease are the most important factors on artificial propagation. Strengthening the genetic management of stock population for keeping a higher genetic diversity can increase the success of stock enhancement. The works on Lixianjiang provide a new model for river fish protection. To make sure the complicated project works well, project plans, commission contracts, base line monitoring and techniques on artificial reproduction must be considered early. Last, fishery conservation should be considered alongside location development.

This publication first indicates some data which illustrate the role, importance and development perspectives of hydroelectricity in terms of energy production and in terms of jobs. It outlines that, due to its high adaptation capacity and flexibility, hydroelectricity is an important factor for territory development, that it has a major role in energy supply safety, in the energy mix, and in decentralised energy production. It proposes an overview of the different types of hydroelectric installations: reservoirs for a flexible production and supply safety, run of river hydro systems for a continuous and renewable energy production, pumped storage power stations for mass storage of electric energy. It proposes an overview of assets of hydroelectric energy: implementation of energy transition on the long term, development of an industrial sector of excellence, a responsible and supportive energy, compatibility between hydroelectricity, biodiversity and water usages. Proposals are then formulated to give electricity a new momentum: a new orientation of national and European policies for a better global consistency, a new orientation of economic choices and tax policy as incentives to maintenance and development of the hydroelectric sector, and a fair compensation of services provided to the electric power system

Monitoring marginal erosion in hydroelectric reservoirs with terrestrial mobile laser scanner
Directory of Open Access Journals (Sweden)
A. M. G. Tommaselli
2014-06-01
Full Text Available Marginal erosions in reservoirs of hydroelectric plants have caused economic and environmental problems concerning hydroelectric power generation, reduction of productive areas and devaluing land parcels. The real extension and dynamics of these erosion processes are not well known for Brazilian reservoirs. To objectively assess these problems Unesp (Univ Estadual Paulista and Duke Energy are developing a joint project which aims at the monitoring the progression of some erosive processes and understanding the causes and the dynamics of this phenomenon. Mobile LASER scanning was considered the most suitable alternative for the challenges established in the project requirements. A MDL DynaScan Mobile LASER M150 scanner was selected which uses RTK for real time positioning integrated to an IMU, enabling instantaneous generation of georeferenced point clouds. Two different reservoirs were choose for monitoring: Chavantes (storage plant and Rosana (run-of-river plant, both in the Paranapanema River, border of São Paulo and Paraná States, Brazil. The monitoring areas are scanned quarterly and analysed with base on the point cloud, meshes, contours and cross sections. Cross sections are used to visualize and compute the rate and the dynamics of erosion. Some examples and quantitative results are presented along with an analysis of the proposed technique. Some recommendations to improve the field work and latter data processing are also introduced.

Dissolved oxygen analysis for hydropower additions on the Illinois River
International Nuclear Information System (INIS)
Sundquist, M.J.; Elver, S.A.
1993-01-01
The Illinois Waterway is comprised of a system of eight locks along the Illinois River, the Des Plaines River, and the Chicago Sanitary Ship Canal which allow commercial barge traffic between the Mississippi River and Lake Michigan at the City of Chicago. Opportunities for production of hydroelectric power is present at several of these lock and dams. This paper presents the field study and computer simulation conducted to determine the feasibility of constructing hydroelectric powerhouses on two of these lock and dams. So as not to degrade recent improvements to water quality, the Federal Energy Regulatory Commission (FERC), in issuing the construction and operating licenses for these two hydroelectric facilities, requires the hydropower additions to not reduce the dissolved oxygen (D.O.) level downstream of the hydroelectric facilities below 6 parts per million (ppm). Presently, the waterway discharge passes through taintor gates at both of these lock and dam facilities which creates aeration. The addition of hydroelectric powerhouses would divert water from these spillways through generation equipment; consequently, the spillway aeration would not occur. The purpose of the study was to determine the amount of power generation from these facilities, given the existing waterway water quality and the FERC D.O. criteria. A computer simulation generation analysis was conducted to provide a database of the waterway water quality. A four-month extensive field collection survey was conducted over the 63 kilometer (39 mile) reach of the waterway which comprises the two downstream pools of the Brandon Road and Dresden Island projects, and 3 kilometers (2 miles) upstream of the Brandon Road Project. The analysis revealed that the hydroelectric additions were economically feasible and are an example of how the benefits of hydroelectric development can be balanced with environmental concerns

NONE
2010-07-01
The Ojibway Power and Energy Group (OPEG) is planning on installing a hydroelectric generating facility along the Namakan River at High Falls in Canada. In order the meet the different requirements in terms of environmental assessment for such a project, the group prepared an environmental report. The aim of this paper is to present the comments of the Quetico Foundation, a charity whose aim is to protect wilderness class parks. The foundation found both general and discipline-by-discipline deficiencies in OPEG's environmental report. All the deficiencies the Foundation observed are listed in this report, general deficiencies, and specific deficiencies concerning fisheries, terrestrial ecology, hydrology and socio-economic impacts. The Quetico Foundation demonstrated that a significant number of deficiencies are found in the OPEG environmental report, suggesting that they did not fully understand the potential long term impacts of their project and that further study should be undertaken.

After nearly a century of producing power, two large hydroelectric dams on the Elwha River in Washington State were removed during 2011 to 2014 to restore the river ecosystem and recover imperiled salmon populations. Roughly two-thirds of the 21 million cubic meters of sediment—enough to fill nearly 2 million dump trucks—contained behind the dams was released downstream, which restored natural processes and initiated important changes to the river, estuarine, and marine ecosystems. A multidisciplinary team of scientists from the Lower Elwha Klallam Tribe, academia, non-governmental organizations, Federal and state agencies, and the U.S. Geological Survey collected key data before, during, and after dam removal to understand the outcomes of this historic project on the Elwha River ecosystem.

This report describes in details the project of the installation of a small-scale hydroelectric power plant on the river Areuse in Switzerland. Located on a 4 m high waterfall the plant includes a 10-13 m{sup 3}/s Kaplan turbine, which should deliver roughly 1.6 GWh/year for an installed power of about 500 kVA. The authors insist on the ecological aspect of the project. The plant will be built underground; the river track will be practically unchanged and the existing fish ladder maintained. The report includes maps and pictures of the site as well as technical drawings of the installation. An economic analysis of the project is presented and its viability is discussed. Finally, the authors state that the energy produced by this plant will certainly be certified under one of the Swiss labels 'naturemade star' or 'naturemade basic', in the framework of the federal government's promotion of renewable energy sources.

Hydroelectric issues have a long history in the Pacific Northwest, and more recently have come to focus on developing environmentally less-obtrusive means of hydroelectric generation. Small-scale hydroelectric represents perhaps the most important of these means of developing new sources of renewable resources to lessen the nation's dependence on foreign sources of energy. Each potential small-scale hydroelectric project, however, manifests a unique history which provides a highly useful opportunity to study the process of collective social choice in the area of new energy uses of water resources. Utilizing the basic concepts of public choice theory, a highly developed and increasingly widely accepted approach in the social sciences, the politicalization of small-scale hydroelectric proposals is analyzed. Through the use of secondary analysis of archival public opinion data collected from residents of the State of Idaho, and through the development of the two case studies - one on the Palouse River in Eastern Washington and the other at Elk Creek Falls in Northern Idaho, the policy relevant behavior and influence of major actors is assessed. Results provide a useful test of the utility of public-choice theory for the study of cases of natural-resources development when public involvement is high.

Manore, J.L. [Calgary Univ., AB (Canada)
1999-05-01
The history of hydroelectric development in northern Ontario was reviewed and analysed with special emphasis on the developments along the Mattagami and Abitibi Rivers. The objective was to examine the important factors that shaped modern hydroelectric development in Canada. System builders, the privately owned Nesbitt Thomson Company, the publicly owned Hydro Electric Power Corporation of Ontario and the eventual evolution of the single power system under Ontario Hydro are chronicled. Broad historical themes such as the technological impacts, regionalism, indigenous rights, plus environmental and economic issues are examined, in addition to an appreciation of the importance of electricity in the manufacturing sector of Ontario, the impact of hydroelectric development on the northern environment and on the northern First Nations, who rely on rivers for their subsistence. Until fairly recently, government policies and interpretations of law often excluded the recognition of Aboriginal uses of river systems, thereby limiting First Nations` peoples ability to practice traditional ways of life. In essence, the book is an account of how the northeastern power system in Ontario shaped the social, political and natural environments and how the development of northeastern power sources by southern power developers shaped the regional interactions between Ontario`s north and south. refs., figs.

Benefits of fish passage and protection measures at hydroelectric projects

Cada, G.F.; Jones, D.W.
1993-01-01
The US Department of Energy's Hydropower Program is engaged in a multi-year study of the costs and benefits of environmental mitigation measures at nonfederal hydroelectric power plants. An initial report (Volume 1) reviewed and surveyed the status of mitigation methods for fish passage, instream flows, and water quality; this paper focuses on the fish passage/protection aspects of the study. Fish ladders were found to be the most common means of passing fish upstream; elevators/lifts were less common, but their use appears to be increasing. A variety of mitigative measures is employed to prevent fish from being drawn into turbine intakes, including spill flows, narrow-mesh intake screens, angled bar racks, and lightor sound-based guidance measures. Performance monitoring and detailed, quantifiable performance criteria were frequently lacking at non-federal hydroelectric projects. Volume 2 considers the benefits and costs of fish passage and protection measures, as illustrated by case studies for which performance monitoring has been conducted. The report estimates the effectiveness of particular measures, the consequent impacts on the fish populations that are being maintained or restored, and the resulting use and non-use values of the maintained or restored fish populations

Run-of-river (ROR) hydroelectric power (HEP) schemes are often presumed to be less ecologically damaging than large-scale storage HEP schemes. However, there is currently limited scientific evidence on their ecological impact. The aim of this article is to investigate the effects of ROR HEP schemes on communities of invertebrates in temperate streams and rivers, using a multi-site Before-After, Control-Impact (BACI) study design. The study makes use of routine environmental surveillance data collected as part of long-term national and international monitoring programmes at 22 systematically-selected ROR HEP schemes and 22 systematically-selected paired control sites. Five widely-used family-level invertebrate metrics (richness, evenness, LIFE, E-PSI, WHPT) were analysed using a linear mixed effects model. The analyses showed that there was a statistically significant effect (p<0.05) of ROR HEP construction and operation on the evenness of the invertebrate community. However, no statistically significant effects were detected on the four other metrics of community composition. The implications of these findings are discussed in this article and recommendations are made for best-practice study design for future invertebrate community impact studies.

1995-09-01
BPA proposes to fund the implementation of the South Fork Snake River Programmatic Management Plan to compensate for losses of wildlife and wildlife habitat due to hydroelectric development at Palisades Dam. The Idaho Department of Fish and Game drafted the plan, which was completed in May 1993. This plan recommends land and conservation easement acquisition and wildlife habitat enhancement measures. These measures would be implemented on selected lands along the South Fork of the Snake River between Palisades Dam and the confluence with the Henry`s Fork, and on portions of the Henry`s Fork located in Bonneville, Madison, and Jefferson Counties, Idaho. BPA has prepared an Environmental Assessment evaluating the proposed project. The EA also incorporates by reference the analyses in the South Fork Snake River Activity/Operations Plan and EA prepared jointly in 1991 by the Bureau of Land Management and the Forest Service. Based on the analysis in the EA, BPA has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an Environmental Impact Statement (EIS) is not required and BPA is issuing this FONSI.

This study investigated the influence of climatic change on the Peribonka water resources system. The impacts of climatic change on hydroelectric power reservoir operations in the region were assessed using a set of operating rules optimized for future hydrological regimes. Thirty climate change projections from 5 climate models, 2 greenhouse gas (GHG) scenarios, and 3 temporal horizons were used in the study. Climatic change projections were then downscaled using the Delta approach and coupled to a stochastic weather generator developed to account for natural variabilities in local climates. A lumped hydrological model was used to simulate future hydrological regimes. A stochastic dynamic programming technique was then used to optimize reservoir operating rules for various time series of future river flows. The operating rules were then used in conjunction with a river system simulation tool in order to determine reservoir and hydroelectric production scenarios under different climatic change regimes. Results of the study showed significant increases in hydroelectricity production for most of the climate change projections. However, nonproductive spillage was also increased. Reservoir reliability was also reduced. tabs., figs

Special design features required in constructing a 2444 m long dyke on the north bank of the La Grade River at the site of the La Grande 1 hydroelectric power project are described. The special features involved construction of a downstream bank and upstream stabilization berms to avoid the occurrence of potentially dangerous retrogressive slides. These special features were deemed essential due to the presence of sensitive marine clay, covered with deltaic sand and silt and river sand deposits. The paper highlights the geotechnical and hydrogeological conditions of the northern terrace, and describes the different construction phases of stabilizing the river bank. Control of groundwater pressures in the lower aquifer with relief wells is emphasized. 9 refs., 1 tab., 17 figs

The potential environmental impacts of large-scale storage hydroelectric power (HEP) schemes have been well-documented in the literature. In Europe, awareness of these potential impacts and limited opportunities for politically-acceptable medium- to large-scale schemes, have caused attention to focus on smaller-scale HEP schemes, particularly run-of-river (ROR) schemes, to contribute to meeting renewable energy targets. Run-of-river HEP schemes are often presumed to be less environmentally damaging than large-scale storage HEP schemes. However, there is currently a lack of peer-reviewed studies on their physical and ecological impact. The aim of this article was to investigate the effects of ROR HEP schemes on communities of fish in temperate streams and rivers, using a Before-After, Control-Impact (BACI) study design. The study makes use of routine environmental surveillance data collected as part of long-term national and international monitoring programmes at 23 systematically-selected ROR HEP schemes and 23 systematically-selected paired control sites. Six area-normalised metrics of fish community composition were analysed using a linear mixed effects model (number of species, number of fish, number of Atlantic salmon-Salmo salar, number of >1 year old Atlantic salmon, number of brown trout-Salmo trutta, and number of >1 year old brown trout). The analyses showed that there was a statistically significant effect (pcomposition. The implications of these findings are discussed in this article and recommendations are made for best-practice study design for future fish community impact studies.

A description is given of the hydroelectric construction project as well as the environment surrounding it, the outcome of consultations with interest parties in the public, the overall environmental impacts and cumulative impacts with associated problems that may occur in carrying out the project, attempts at project and environmental mitigation, measuring the importance of the cumulative and environmental effects, conditions for project acceptance, and the overall acceptance of the project or its rejection. The older hydroelectric project was constructed in the post-1910 period and being out of date is experiencing operational problems. There are four problem areas that are important including a need for major repairs to the turbine-generators, lack of flexibility and low electrical capacity that affect the working of the sending-end substation, a state of deterioration affecting operation of the spillways concrete structure, and a bottleneck problem on the Saint-Maurice river caused by the low flow design of the Grand-Mere power station in comparison with that of the Saint-Maurice station. Considering economical, social and environmental factors, of the three options of abandoning the site, upgrading the existing site or constructing a new one, the third option is the preferred one, a conclusion based on considering the out of date state of Grand-Mere facilities and the bottleneck flow condition created on the Saint-Maurice river by the older station. Given the proposed efforts at mitigation, and the follow-up operations stated by the third option advocate, the Department of Fisheries and Oceans is of the opinion that the proposed plans will not affect the environment in an adverse manner. 7 refs

We investigate scenarios of hydroelectric power generation for an Alpine run-of-the-river plant in 2050. To this end, we include a conversion from streamflow to energy in a hydrological model of the basin, and we introduce a set of benchmark climate scenarios to evaluate expected future production. These are a "future-like-present" scenario assuming future precipitation and temperature inputs to be statistically equivalent to those observed during the recent past at the same location, a "warmer-future" scenario, which considers an additional increase in temperature, and a "liquid-only" scenario where only liquid precipitation is admitted. In addition, two IPCC-like climatic scenarios (RCP 4.5 and RCP 8.5) are considered. Uncertainty in glaciers' volume is accounted by initializing the hydrological model with two different inventories of glaciers. Ensemble results reveal that 1) an average decrease between -40% and -19% of hydroelectric power generation in 2050 is predicted at the plant considered (with respect to present condition); 2) an average decrease between -20% and -38% of cumulative incoming streamflow volume at the plant is also predicted, again with respect to present condition; 3) these effects are associated with a strong average decrease of the volume of glaciers (between -76% and -96%, depending on the initial value considered). However, Monte Carlo simulations show that results are also prone to high uncertainties. Implications of these results for run-of-the-river plants are discussed.

Potential environmental impacts in reservoirs and downstream river reaches below dams that may be caused by the water level fluctuation resulting from development and operation of small scale (under 25MW) hydroelectric projects are identified. The impacts discussed will be of potential concern at only those small-scale hydroelectric projects that are operated in a store and release (peaking) mode. Potential impacts on physical and chemical characteristics in reservoirs resulting from water level fluctuation include resuspension and redistribution of bank and bed sediment; leaching of soluble organic matter from sediment in the littoral zone; and changes in water quality resulting from changes in sediment and nutrient trap efficiency. Potential impacts on reservoir biota as a result of water level fluctuation include habitat destruction and the resulting partial or total loss of aquatic species; changes in habitat quality, which result in reduced standing crop and production of aquatic biota; and possible shifts in species diversity. The potential physical effects of water level fluctuation on downstream systems below dams are streambed and bank erosion and water quality problems related to resuspension and redistribution of these materials. Potential biological impacts of water level fluctuation on downstream systems below dams result from changes in current velocity, habitat reduction, and alteration in food supply. These alterations, either singly or in combination, can adversely affect aquatic populations below dams. The nature and potential significance of adverse impacts resulting from water level fluctuation are discussed. Recommendations for site-specific evaluation of water level fluctuation at small-scale hydroelectric projects are presented.

The seaward migration of juvenile salmonids was monitored by the National Marine Fisheries Service (NMFS) at Bonneville and John Day Dams on the Columbia river in 1995. The NMFS Smolt Monitoring Project is part of a larger Smolt Monitoring Program (SMP) coordinated by the Fish Passage Center (FPC) for the Columbia Basin Fish and Wildlife Authority. This program focuses on protecting, mitigating, and enhancing fish populations affected by the development and operation of hydroelectric power plants on the Columbia River. The purpose of the SMP is to monitor the migration of the juvenile salmonid stocks in the Columbia basin and make flow and spill recommendations designed to facilitate fish passage. Data are also used for travel time, migration timing, and relative run size analysis. The purpose of the NMFS portion of the program is to provide FPC with species and project specific real time data from John Day and Bonneville Dams

Due to their operational flexibility, hydroelectric dams are ideal candidates to compensate for the intermittency and unpredictability of wind energy production. However, more coordinated use of wind and hydropower resources may exacerbate the impacts dams have on downstream environmental flows, that is, the timing and magnitude of water flows needed to sustain river ecosystems. In this paper, we examine the effects of increased (i.e., 5%, 15%, and 25%) wind market penetration on prices for electricity and reserves, and assess the potential for altered price dynamics to disrupt reservoir release schedules at a hydroelectric dam and cause more variable and unpredictable hourly flow patterns (measured in terms of the Richards-Baker Flashiness (RBF) index). Results show that the greatest potential for wind energy to impact downstream flows occurs at high (∼25%) wind market penetration, when the dam sells more reserves in order to exploit spikes in real-time electricity prices caused by negative wind forecast errors. Nonetheless, compared to the initial impacts of dam construction (and the dam's subsequent operation as a peaking resource under baseline conditions) the marginal effects of any increased wind market penetration on downstream flows are found to be relatively minor.

Tucurui was the first big hydroelectric built in the Brazilian Amazonia (river Tocantins, Para). About 2400 Km 2 of Tropical Rain Forest was inundated. This work attempts to describe some effects of the Tucurui dam upon fish communities of the lower Tocantins river. Surveys of fish communities on the Tocantins were carried out by INPA, before and after the impoudment. Fishes belonging to 223 species was sampled by gillnets. After the impoudment, the average of species richness of the communities was reduced in 42% and 50%, respectively downstream and upstream the dam. In the reservoir, where rapids were flooded, species specialized in this habitats virtually disappeared during and after the filling up phase. The relative contribution of the illiophagous, that dominated the samples before the dam closure, downed, while there has been a sudden widespread of fish predators species in the reservoir. These predators dominated until the third year after the impoudment. The cluster analysis provide evidences that, between the species that take advantages of the impoundment, exist a clear succession of dominance. Until the end of sampling period all the study-area remained very instable, so is difficult to foresee the future composition or structure of the communities in the area under influence of Tucurui's Hydroelectric Dam.

In economic terms, hydro-electricity is considered as a quasi-staple, as it prone to the classic staples problem of excess capacity. However, neither water nor hydroelectricity in Canada is produced primarily for export markets. Hydroelectric systems are often thought of as politicized monopolies. This paper discussed changes that have occurred in hydroelectric organizations over time, as they have been governed by a formative mixed regime; postwar provincial hydro systems; a megaprojects regime; and an emerging sustainability regionalization regime. The origins of electricity generation and transmission in Canada were discussed, as well as the ecological footprint of large mega-projects on rivers. The development of provincial hydro monopolies during the mid- to late- twentieth century was also outlined, as well as the sustainability and regionalization regime that developed after 1990. During the mature staples period of the mid-century, rents in hydro-electric organizations were distributed through cheap rates to subsidize and facilitate the development of mass production and mass consumption. However, post-staples consumption has now replaced mass consumption, and demand side management is replacing earlier cheap power policies. Nonetheless, the lack of systematic integration of networks has led to inefficiencies. Provincial grids are now being integrated into interconnected North American regional networks regulated by the United States. It was concluded that the Canadian electricity regime is increasingly influenced by the the supranational role that the United States is playing in structuring markets. 83 refs

This report evaluated an environmental impact statement (EIS) submitted by a company proposing to develop a hydroelectric generation project in the lower Churchill River in Labrador. Construction of the facilities will alter the aquatic environment of the river as well as the receiving environment of lakes. The alterations are expected to have an impact on fish and fish habitats. The study evaluated the methods used to describe and predict impacts in the aquatic environment and examined models used for predictions in order to assess uncertainty levels. Results of the evaluation demonstrated that additional efforts are needed to document local knowledge of fish use and fish habitat, and that the magnitude of expected changes to fish habitat must be considered relative to the loss of fish habitat. The study also highlighted areas within the EIS that will require further clarification. A number of the studies used in the EIS had small sample sizes that increased the uncertainty of predictions made using the data. Uncertainties related to potential changes in flushing rates and morphological features was also needed. The impact of direct fish mortality from turbine operations was not addressed in a population context, and further information is needed to evaluate potential project-related effects on a species-by-species basis. 3 refs., 4 tabs.

The legal and institutional obstacles to the development of small-scale hydroelectric in West Virginia at the state level are described. The Federal government also exercises extensive regulatory authority in the area. The introductory section examines the dual regulatory system from the standpoint of the appropriate legal doctrine, the law of pre-emption, application of the law to the case of hydroelectric development, and concludes with an inquiry into the practical use of the doctrine by FERC. The development of small-scale hydroelectric energy depends on the selection of a site which will produce sufficient water power capacity to make the project economically attractive to a developer. In West Virginia, the right to use the flowing waters of a stream, creek, or river is appurtenant to the ownership of the lands bordering the watercourse. The lands are known as riparian lands. The water rights are known as riparian rights. Thus, the first obstacle a developer faces involves the acquisition of riparian lands and the subsequent right to the use of the water. The water law in West Virginia is discussed in detail followed by discussions on direct and indirect regulations; continuing obligations; financial considerations; and interstate organizations.

Methane and CO2 emissions from China's hydroelectric reservoirs: a new quantitative synthesis.
Li, Siyue; Zhang, Quanfa; Bush, Richard T; Sullivan, Leigh A
2015-04-01
Controversy surrounds the green credentials of hydroelectricity because of the potentially large emission of greenhouse gases (GHG) from associated reservoirs. However, limited and patchy data particularly for China is constraining the current global assessment of GHG releases from hydroelectric reservoirs. This study provides the first evaluation of the CO2 and CH4 emissions from China's hydroelectric reservoirs by considering the reservoir water surface and drawdown areas, and downstream sources (including spillways and turbines, as well as river downstream). The total emission of 29.6 Tg CO2/year and 0.47 Tg CH4/year from hydroelectric reservoirs in China, expressed as CO2 equivalents (eq), corresponds to 45.6 Tg CO2eq/year, which is 2-fold higher than the current GHG emission (ca. 23 Tg CO2eq/year) from global temperate hydropower reservoirs. China's average emission of 70 g CO2eq/kWh from hydropower amounts to 7% of the emissions from coal-fired plant alternatives. China's hydroelectric reservoirs thus currently mitigate GHG emission when compared to the main alternative source of electricity with potentially far great reductions in GHG emissions and benefits possible through relatively minor changes to reservoir management and design. On average, the sum of drawdown and downstream emission including river reaches below dams and turbines, which is overlooked by most studies, represents the equivalent of 42% of the CO2 and 92% of CH4 that emit from hydroelectric reservoirs in China. Main drivers on GHG emission rates are summarized and highlight that water depth and stratification control CH4 flux, and CO2 flux shows significant negative relationships with pH, DO, and Chl-a. Based on our finding, a substantial revision of the global carbon emissions from hydroelectric reservoirs is warranted.

Hydropower generation induces artificial fluctuations of flow and thus of hydrodynamic parameters in rivers, downstream of hydroelectric impoundments. On the Fontauliere river (Ardeche basin, France), the ecological effects of two different hydro-peaking regimes were tested and compared to a reference upstream reach. Fish, invertebrate and epilithic communities were surveyed in these reaches. The results enables to classify the factors responsible for the observed effects. The base flow between peaks was the most important for the studied site. When it was too low, aquatic communities were de-structured in comparison with the natural reach. These results enabled to suggest a current velocity threshold to respect in order to determine acceptable base flow for this type of stream. They also enabled to guide for the impact evaluation of hydro-peaking sites. An ecological diagnosis should include the study of the structure and composition of the communities.

Full Text Available The article deals with the landscape and urbanistic layout of the Sava River space and North part of the Bežigrad stretch of Ljubljana. Focus is on methodological and content starting points for the layout preparation and development of urban green areas of the wider Sava River space, which as a connecting link and simultaneously independent spatial and functional entity represents the starting point for planning hydro-energetic and urban arrangements. The necessity of recognising and resolving real spatial planning issues, formulation of clear goals and concepts, confrontation of different spatial systems and interests, as well as the sensibility of devising alternative development scenarios are emphasised. One of the most important starting points of the proposed layout is comprehensive design of public open spaces and green areas. The urbanistic solution relies on a programmatically strong, distinct and structured Dunajska Street, which should transform into the public space of a modern urban artery, with a clear ending that simultaneously gradually adapts to the morphology akin to the surroundings and Sava River space. Because of its natural characteristics, preserved cultural landscape and good accessibility, this area has great potential for development of leisure activities. The proposed solution stems from the fact that the chain of hydro-electric plants shouldn't be seen as buildings with negative environmental effects, but also as development opportunities – the actual execution of a recreation area along the Sava River and a method for rehabilitating the degraded spaces. Comprehensive solutions along the river have been proposed as parts of the hydro-electric developments, with special attention focusing on active design of various riverbank types.

By the end of this century higher temperatures and significantly reduced rainfall are projected for the Brazilian North and Northeast (NE) regions due to Global Warming. This study examines the impact of these long-term rainfall changes on the Brazilian Northeast's hydroelectric production. Various studies that use different IPCC models are examined in order to determine the average rainfall reduction by the year 2100 in comparison to baseline data from the end of the 20th century. It was found that average annual rainfall in the NE region could decrease by approximately 25-50% depending on the emissions scenario. Analysis of historical rainfall data in the São Francisco basin during the last 57years already shows a decline of more than 25% from the 1961-90 long-term average. Moreover, average annual rainfall in the basin has been below its long-term average every year bar one since 1992. If this declining trend continues, rainfall reduction in the basin could be even more severe than the most pessimistic model projections. That is, the marked drop in average rainfall projected for 2100, based on the IPCC high emissions scenario, could actually eventuate before 2050. Due to the elasticity factor between rainfall and streamflow and because of increased amounts of irrigation in the São Francisco basin, the reduction in the NE's average hydroelectric production in the coming decades could be double the predicted decline in rainfall. Conversely, it is estimated that wind power potential in the Brazilian NE will increase substantially by 2100. Therefore both wind and solar power will need to be significantly exploited in order for the NE region to sustainably replace lost hydroelectric production. Copyright © 2018 Elsevier B.V.

This report discusses the possible environmental consequences of a planned hydroelectric power development of the river Grunnaai, Norway. The consequences are found to be small, provided the proper counter measures are taken. Without counter measures, there may be moderate consequences on fish populations and botanical conditions, directly dependent on the changed water flow. The greatest value of the area concerned lies in its unspoiled wilderness character. There are extensive lists of birds and mammals and plant species registered in the river valley. 51 refs., 7 figs., 4 tabs.

This work shows the problems of the refurbishing the hydroelectric units of the Iron Gates 1 Hydroelectric and Navigation System, operating since 1970. Their long and intensive utilization leads to the necessity of their refurbishment. One is demonstrated by detailed studies that it is sensible and efficient to perform both rehabilitation of the existent hydroelectric units and their power increasing from 175 MW to 190 MW, and prior to all these, as a first step, to install an additional hydroelectric unit (G7) for each system with a capacity of 190 MW. Complex technical and energetic-economical problems appear in realizing this objective due to the necessity of analysing a great volume of data in view of taking a correct decision. (author). 7 figs

Physical, chemical, biological, ecological, and aesthetic aspects of the Wairakei Power Plant are examined, in varying detail, but with primary emphasis on the chemical and thermal effluents. When flows are average or higher in the Waikato River, the Plant's environmental effects are not overly severe. However, operating requirements for the Waikato Hydro-electric System are such that the Plant sporadically produces wastes that may affect the human and natural environment adversely. These adverse effects are not presently too serious, but suggestions are made for improving the Plant's overall environmental performance. Although the point is not discussed in detail, it is clear from the results of the study that any additional thermal plants on the Waikato could strain the river's absorptive capacities severely, unless alternative disposal techniques are used for the various effluents.

Power generation in Canada is a provincial responsibility. Since Quebec does not possess petroleum, natural gas or coal deposits, the Quebec government decided, in the 1970s, to develop hydroelectric resources in the northern regions of the province. This paper presents a brief historical overview of the hydroelectric development of the La Grande River project, also referred to as the James Bay project. Located approximately 1000 kilometres north of Montreal, the La Grande project lies in a humid continental climate with an average winter temperature of - 23 Celsius and an average summer temperature of 14 Celsius. The construction of the dam was not preceded by an environmental impact assessment, but environmental data was collected for the first time before construction began. It was an opportunity for all environmental sciences to develop inventory methodologies and analysis techniques specific to northern regions applicable to hydroelectric development. This project also required the signing of the James Bay and Northern Quebec Agreement by the governments of Canada and Quebec, Hydro-Quebec, and the Crees and Inuit of Quebec. The Agreement covers an area of 1 million square kilometres. As a result, Hydro-Quebec has become, over the past 30 years, a leader in environmental assessments and studies in the province. In northern Quebec, a hydroelectric reservoir constitutes an ecosystem whose biological productivity is comparable to a natural lake or ecosystem of equal area. During the first 5 years after flooding, reservoirs possess water quality slightly below that of a natural lake, but still favorable to biological development. The flooding of areas and the subsequent organic degradation promote mercury methylation and its accumulation in the food chain. The emissions of greenhouse gases by northern reservoirs are minimal compared to tropical reservoirs. The fauna in northern Quebec suffered habitat loss, but none became endangered.

Evaluate Status of Pacific Lamprey in the Clearwater River Drainage, Idaho: Annual Report 2001.
Energy Technology Data Exchange (ETDEWEB)
Cochnauer, Tim; Claire, Christopher
2002-12-01
Recent decline of Pacific lamprey Lampetra tridentata adult migrants to the Snake River drainage has focused attention on the species. Adult Pacific lamprey counted passing Ice Harbor Dam fishway averaged 18,158 during 1962-69 and 361 during 1993-2000. Human resource manipulations in the Snake River and Clearwater River drainages have altered ecosystem habitat in the last 120 years, likely impacting the productive potential of Pacific lamprey habitat. Timber harvest, stream impoundment, road construction, grazing, mining, and community development have dominated habitat alteration in the Clearwater River system and Snake River corridor. Hydroelectric projects in the Snake River corridor impact juvenile/larval Pacific lamprey outmigrants and returning adults. Juvenile and larval lamprey outmigrants potentially pass through turbines, turbine bypass/collection systems, and over spillway structures at the four lower Snake River hydroelectric dams. Clearwater River drainage hydroelectric facilities have impacted Pacific lamprey populations to an unknown degree. The Pacific Power and Light Dam on the Clearwater River in Lewiston, Idaho, restricted chinook salmon Oncorhynchus tshawytscha passage in the 1927-1940 period, altering the migration route of outmigrating Pacific lamprey juveniles/larvae and upstream adult migrants (1927-1972). Dworshak Dam, completed in 1972, eliminated Pacific lamprey spawning and rearing in the North Fork Clearwater River drainage. Construction of the Harpster hydroelectric dam on the South Fork of the Clearwater River resulted in obstructed fish passage 1949-1963. Through Bonneville Power Administration support, the Idaho Department of Fish and Game continued investigation into the status of Pacific lamprey populations in Idaho's Clearwater River drainage in 2001. Trapping, electrofishing, and spawning ground redd surveys were used to determine Pacific lamprey distribution, life history strategies, and habitat requirements in the South

1993-01-01
The Ontario Ministry of Natural Resources released a Crown owned site to the private water power industry as part of the small hydro site release program initiated by the Ontario Government in the mid 1980's. The Cordova Lake Dam Hydroelectric Generating Station, built on this site, has been in operation since the first week of October, 1992. Since that time, the plant has been operating with less than 1 % down time and has generated over 2,400 MWh of electricity. Algonquin Power Systems is responsible for the management and operations of the plant which includes full time monitoring from the company's Mississauga office and a part time employee at Cordova Lake. Cordova Lake Dam is located on the Crowe River at the outlet of Cordova Lake, approximately 125 kilometers east of Toronto, Ontario. The total cost of the Cordova Lake Dam project was $1.6 million. Algonquin Power contributed 20% equity to the project. Algonquin Power was also responsible for all engineering and geotechnical work and for completing the construction and equipment contracts. 1 tab., 2 figs

Use of mediation to resolve the dispute over low-head hydroelectric development at Swan Lake
Energy Technology Data Exchange (ETDEWEB)
O' Connor, D.
1980-08-01
In 1978, the Maine Hydroelectric Development Corporation announced that the company planned to renovate five dams on the Goose River near Belfast, Maine to generate electricity. The most important part of the plan involved the use of the first of the dams, at the lower end of Swan Lake, to regulate the flow of water to the downstream dams. For Maine Hydro, management of the Swan Lake dam could make an otherwise marginal proposal lucrative. However, Swan Lake is vitally important to the residents of Swanville. The town was so concerned about the impact of this proposed hydroelectric project that it petitioned the Federal Energy Regulatory Commission (FERC) to deny Maine Hydro's application on the grounds that it would damage the environment, reduce property values and eliminate recreational opportunities for its citizens. This report was written by the mediator of the dispute and represents the views and behavior of the parties as the mediator understood them. It is intended to present the mediator's observations in a way which will inform and assist others who may someday face a difficult situation like the one the Town of Swanville and Maine Hydroelectric Development Corporation faced, and successfully resolved, in the spring and summer of 1979.

People's perception on impacts of hydro-power projects in Bhagirathi river valley, India.
Negi, G C S; Punetha, Disha
2017-04-01
The people's perception on environmental and socio-economic impacts due to three hydro-electric projects (HEPs; commissioned and under construction) were studied in the north-west Indian Himalaya. Surveys among 140 project-affected people (PAPs) using a checklist of impacts indicate that among the negative impacts, decrease in flora/fauna, agriculture, flow of river, aesthetic beauty; and increase in water pollution, river bed quarrying for sand/stone, human settlement on river banks and social evils; and among the positive impacts, increase in standard of living, road connectivity, means of transport, public amenities, tourism and environmental awareness were related with HEPs. The PAPs tend to forget the negative impacts with the age of the HEPs after it becomes functional, and the positive impacts seem to outweigh the negative impacts. Study concludes that it is difficult to separate the compounding impacts due to HEP construction and other anthropogenic and natural factors, and in the absence of cause-and-effect analyses, it is hard to dispel the prevailing notion that HEPs are undesirable in the study area that led to agitations by the environmentalists and stopped construction of one of these HEPs. To overcome the situation, multi-disciplinary scientific studies involving the PAPs need to be carried out in planning and decision-making to make HEPs environment friendly and sustainable in this region. There is also a need to adopt low carbon electric power technologies and promote a decentralized energy strategy through joint ventures between public and private companies utilizing locally available renewable energy resources.

Fuzzy logic approach for energetic and economic evaluation of hydroelectric projects
International Nuclear Information System (INIS)
Iliev, Atanas M.
2003-01-01
A mathematical model for energetic and economic evaluation of hydroelectric projects is developed. The main advantage of the proposed methodology is that the model considers uncertainty and vagueness which appears during the decision making process. Due to modeling of variables that are non statistical in their character, fuzzy logic approach is fully incorporated in the model. The first step in energetic evaluation of the hydro power projects is determination of the characteristic of the efficiency of the units to be installed in hydro power plants. For this purpose the model which uses the best characteristics of Artificial Network Fuzzy Inference System (ANFIS) is applied. The method is tested on real systems: HPP Tikves- the power plant in operation and HPP Kozjak - the power plant in construction. The results obtained from practical implementation show that the proposed approach gives superior results than classical polynomial approximation. The model for determining the consumption characteristic of hydro power plant is developed by Sugeno Fuzzy Logic System with polynomials in the consequent part of the rules. Model takes into account the variable gross head of HPP, as well as, the number of units which will be in operation for given output. Modeling of the gross head and power output are performed by expert's design membership functions. This model is practically applied on HPP Tikves for determination of the consumption characteristic for several gross head. The plausible yearly production of electricity from hydro power project, which is important for estimation of the benefit from the project, is calculated by mixed fuzzy-statistical model. hi this approach fuzzy set of the inflow is constructed according to the statistical parameters. The calculation of the production of electricity is realized for a several hydrological conditions which are described by linguistic variables. Finally, Mamdani Fuzzy Inference System with fuzzy number in consequent part

Climate change and hydroelectric production
International Nuclear Information System (INIS)
Raban, R.R.
1991-01-01
Manitoba Hydro is planning for the possibility of climate change, which has the potential to adversely effect its hydroelectric generating potential. Theoretical and physical evidence for a global warming are reviewed, and it is shown that some of Manitoba Hydro's own measurements support a warming hypothesis. The most significant effect on the hydraulic generating system would be associated with diminished river flows. Winter hydraulic generation capability would be reduced if the magnitude of the change were sufficient to cause several freeze-ups and break-ups within a given season. Incidence of transmission line icing would probably increase, permafrost recession may undermine tower foundations, and conductor resistance may increase to increase energy loss. Ice crossings and winter roads would be adversely affected, and a restriction on fossil fuel consumption could limit thermal generation and increase demand for hydroelectric or nuclear energy. Manitoba Hydro is examining a number of no-cost or low-cost options to accomodate potential climate change, using probable maximum precipitation hydrologic technology, research into conductor galloping, line icing detection, and hydrological investigations

A detailed summary is provided from five major water quality studies undertaken in northern Manitoba to assess the effects of hydroelectric projects on water quality. Physical changes occurring with the area affected by both the Churchill River diversion and Lake Winnipeg regulation have led to water quality changes in many cases. Phosphorus appeared to increase at some sites while decreasing at others, reflecting a new balance between erosion of new P sources and later uptake or deposition. Color declined at all sites except at Red Head Rapids. Turbidity increased in Southern Indian Lake and in the Burntwood River at Thompson in response to the Churchill diversion, but turbidity has historically exceeded drinking water quality objectives. It is unclear whether the observed changes in water chemistry may have the potential to directly impact aquatic life and wildlife. A major limitation of the water quality data set is the lack of pre-development data for many of the trace elements analyzed. Relative to an upstream reference site, concentrations of Cu, Pb, and Zn were slightly higher at some sites affected by hydroelectric development, but it is not known whether this condition existed prior to development. Exceedances of water quality objectives for some trace elements occurred intermittently at some sites but it is not possible to determine whether these exceedances occurred infrequently historically as a result of natural variability. 34 refs., 1 fig., 13 tabs

Full Text Available Opponents of hydroelectricity claim falsely that hydrotechnical development of the Lower Vistula River constitutes implementation of Edward Gierek’s concept of bringing only environmental damage1. Statements on the negative environmental impact of constructing small hydroelectric power stations (SHPS are equally groundless. Permanent protests against the construction of dams and river damming, regardless of the motivations and will of protesters, increase energy dependence on Russia, and preserves the poor, post-Bierut hydrological situation2. The main fallacy made by hydropower opponents is the alternative treatment of power and environmental purposes. Environmental errors consist in continuous omission of even the most obvious positive ecological effects of constructing river dams and – what is especially reprehensible – inventing non-existent threats, e.g. lethal concentration of toxic heavy metals in deposits of the Włocławek Reservoir or the detrimental impact of warming up water in stage of falls on the fish population below the dam.

Externality costing for hydroelectric projects: Is it desirable? Is it possible?
International Nuclear Information System (INIS)
Bernier, L.
1992-01-01
The assignment of monetary values to environmental and social impacts of hydroelectric projects is discussed. The strengths and weaknesses of the economic approach to externality costing are noted. The problem to be faced is that environmental externalities associated with a hydro project very often involve resources that have little or no relation with the market, such as disturbances of land not used for commercial activities. The valuation of externalities related to thermal power plants is examined to provide lessons for quantifying the externalities of hydro projects. One observation is that there is very little information on the real impacts of such phenomena as the release of greenhouse gases, making quantification of their effect difficult; another is that impacts from atmospheric emissions are well in excess of simple deterioration of material goods or recreational activities that have some relationship to the market. Applied to hydro projects, the lessons from these observations indicate that there are no exact and homogeneous measurement units for impacts of actions such as diking or alteration of wildlife habitats. One approach that has been tried is the contingent valuation method, which relies on asking respondents how much they would pay to avoid an impact or risk. This approach is criticized and it is suggested to experiment with a review of the tradeoffs between several possible environmental impacts defined in a precise manner

Effectiveness of water release as mitigation for hydroelectric impacts to fish
International Nuclear Information System (INIS)
Lewis, A.F.; Mitchell, A.C.
1995-01-01
Utility companies release water to mitigate the effects of hydroelectric projects on fish habitats. Utility companies, government agencies, and research communities in Canada, the US, Europe, New Zealand, and Australia were surveyed as part of a Canadian Electrical Association study to evaluate the effectiveness of water release as a mitigation. Respondents identified only 28 projects in which water was released specifically to protect fish habitats. Fewer than half of these projects (12) were judged as being effective. Six case histories with preimpact assessment and postimpact monitoring were reviewed. In four cases fish habitat or fish populations or both were maintained; in two cases they were not. The effectiveness of water release differed among rivers and fish species, and was greatest when designed to meet the habitat requirements of each life-history stage. A review of the literature did not support the theory that a particular fraction of the mean annual flow provides the bet fish habitat. Although smaller changes in the flow regime had smaller effects, increasing minimum flows above those historically observed did not necessarily increase fish production

Full Text Available Each big river, including the Danube, makes a single system from their spring to their delta or estuary. Wherever we intervene into the system, this will be necessarily affect the whole of that. Thespillover effects are especially striking in the case of the lower reaches, in the Danube River in the Delta area. The utilisation of the hydroelectric power of the Danube River has been continuously on the agenda in the Hungarian areas since the turn of the 19th and 20th centuries, as an economic, planning, development and thenpolitical and environmental issue. The plans made before the World War I featured hydroelectric plants as the carriers of technical and scientific progress. World War I and the subsequent changes of the state borders swept these plans aside. Between the two world wars, the planning of hydroelectric power stations on the Danube wascontinued within the new state borders, two Hungarian governments and prime ministers of the time were fully committed to the construction of three power plants on the Danube River. After World War II, the hydroelectric plant planned on the Hungarian-Czechoslovakian border and its construction became a basic economic and, from the 1980s, an environmental issue. Finally, only a part of the planned hydroelectric power plant system was constructed, and the issue was not finally closed by specific interpretation of the international law. The Danube Strategy of the European Union, the programmes until 2020, the increase of the role of renewable anergies, the nuclear disaster in Japan, and the interests of international navigation filled the debate with new content. Thepossibility of the construction of hydroelectric power plants on the Danube River was “accidentally” put among the official documents of the government in power since 2010. The government declared it had nothing to do with the plans, and the debate has been going on since then.

Hydroelectric developments built in the early 1900's are nearing their useful lifespan and require significant rehabilitation in order to meet modern safety and performance criteria. Also, global increasing energy costs represent a strong incentive for operators to find low-cost, environment-friendly solutions while increasing energy generation at existing facilities. Projects promoting innovative ways of recycling existing developments are great examples of sustainable development and represent win-win solutions for population and hydropower industry alike. The proposed presentation describes successful projects consisting in the rehabilitation or addition of power to existing hydroelectric. These recycling projects are very attractive from both economic and environmental.

By their dimensions hydroelectric constructions constitute one of the evident examples of man's action upon nature, with favorable as well as unfavorable effects. By using past experience, such effects can be correctly establish and evaluated both by specialists from different fields and by representatives of the local population. The paper proposes several criteria for qualitative characterization of such effects. Some favorable and unfavorable effects of dams, lakes, secondary catchment and derivations are discussed. Also, having in view the water flow distribution which would allow a normal insertion of such construction in the environment, despite of some power production diminish diminishing, two proposals are made concerning possible solutions for secondary catchment and the hydroelectric power stations situated in the upper zones of the rivers.

Environmental consequences of hydroelectric development: the role of facility size and type
International Nuclear Information System (INIS)
Gleick, P.H.
1992-01-01
The development of hydroelectric power throughout the world is receiving renewed attention as the economic, political, and environmental costs of conventional energy production rise. There is currently a perception that hydroelectricity has environmental and economic advantages over electricity produced by conventional energy technologies, but there is a paucity of information about the environmental impacts of hydroelectric facilities as a function of size and type. We characterize the environmental impacts of hydroelectric developments and quantify these impacts as a function of the size and type of project. Several unexpected conclusions arise from our analysis. For most hydroelectric facilities, size, as measured by installed capacity, is not necessarily a good indicator or the severity of environmental costs. For impacts such as land flooded and evaporative water lost, smaller facilities cause greater environmental disruptions per unit of energy produced than do larger facilities. (Author)

Etan hydropower project spurs industrial, agricultural growth of region
Energy Technology Data Exchange (ETDEWEB)
1982-01-01
Located in Hongdu commune, Xincheng County, Guangxi Zhuang Autonomous Region, on the middle reaches of the Hongshui River, the Etan hydroelectric power station was begun in 1977 and began to generate power in April 1981. The Etan hydroelectric power station is a run-off type, low waterhead medium-sized power station. It has an installed capacity of 60,000 kW for an average yearly power output of 328 million kWh. The main structure of the power station includes a water diversion canal, a water intake gate, a main machinery building and a switching station. The main machinery building is located on the downstream side of the dam on an overhanging cliff. With a construction area of only 5000 m/sup 2/, work was very difficult due to the restricted work area and transportation problems. By strengthening construction management and promoting technical innovation some 670,000 yuan were saved for the state and construction time was accelerated. This assured the completion of the construction and installation of the main parts of the project according to timetables and design requirements. The successful construction of the Etan hydroelectric power station marks another step in amassing experience in the harnessing of the Hongshui River. The project will have a major impact on the growth of industry and agriculture in Guangxi and on the buildup of the minority regions.

1999-01-01
Public consultations were held by the Public Advisory Committee, the Ontario Ministry of Natural Resources (MNR) and Ontario Hydro (OH) Working Group and Steering Committee, in an effort to develop a water management system for the Madawaska River, that would address public interests such as public safety, maintenance of the aquatic ecosystem and hydroelectric power generation. Provision of long-term opportunities for broad public involvement in the river's management was an additional objective. The report emphasizes the importance of limiting conflicts between hydroelectric generation and recreation/tourism on the Madawaska River, which runs within the Madawaska Highlands, Algonquin Provincial Park and the Upper Ottawa Valley. The major competing uses for water management in the Madawaska River are: (1) hydroelectric generation, (2) flood control, (3) recreation and tourism, and (4) fish and aquatic ecosystems. Each of these are described in detail, with details of the responses to the issue description and recommended actions

A new methodology relating basic climatic variables to hydroelectric generation was developed. The methodology can be implemented in large or small basins with any number of hydro plants. The method was applied to the Sacramento, Eel and Russian river basins in northern California where more than 100 hydroelectric plants are located. The final model predicts the availability of hydroelectric generation for the entire basin provided present and near past climate conditions, with about 90% accuracy. The results can be used for water management purposes or for analyzing the effect of climate variability on hydrogeneration availability in the basin. A wide range of results can be obtained depending on the climate change scenario used. (Author)

Testing of an acoustic smolt deflection system, Blantyre hydroelectric power scheme
International Nuclear Information System (INIS)
1996-01-01
The aim of this study was to test the effectiveness of an underwater acoustic barrier as a means of preventing the entry of salmon (Salmo salar) and sea trout (Salmo trutta) smolts and other fish into the water intake of a hydro-electric power (HEP) station. A secondary objective was to measure the injury rate of fish passed through the turbine, so that the risk to any fish that penetrated the acoustic barrier could also be determined. The test site, which was a 575kW Kaplan plant located at Blantyre on the R. Clyde, Lanarkshire, was selected as being representative of run-of-river sites currently being developed under the Government's NFFO (Non-Fossil Fuel Obligation) and SRO (Scottish Renewables Order) schemes. A further objective was to disseminate information arising from the project to the scientific and HEP community. (author)

Using fire dynamics simulator to reconstruct a hydroelectric power plant fire accident.
Chi, Jen-Hao; Wu, Sheng-Hung; Shu, Chi-Min
2011-11-01
The location of the hydroelectric power plant poses a high risk to occupants seeking to escape in a fire accident. Calculating the heat release rate of transformer oil as 11.5 MW/m(2), the fire at the Taiwan Dajia-River hydroelectric power plant was reconstructed using the fire dynamics simulator (FDS). The variations at the escape route of the fire hazard factors temperature, radiant heat, carbon monoxide, and oxygen were collected during the simulation to verify the causes of the serious casualties resulting from the fire. The simulated safe escape time when taking temperature changes into account is about 236 sec, 155 sec for radiant heat changes, 260 sec for carbon monoxide changes, and 235-248 sec for oxygen changes. These escape times are far less than the actual escape time of 302 sec. The simulation thus demonstrated the urgent need to improve escape options for people escaping a hydroelectric power plant fire. © 2011 American Academy of Forensic Sciences.

Hydroelectricity and sustainable development
International Nuclear Information System (INIS)
Dubeau, D.
1995-01-01
From 1975 to 1992, hydroelectricity helped reduce greenhouse gas emissions in Quebec by 20%. For Hydro-Quebec, energy conservation and hydroelectric development are basic complementary tools for sustainable development. Recent studies show that developing only 50% of economically exploitable hydroelectric potential (30% of the gross theoretical potential) of different regions worldwide would considerably reduce greenhouse gas and SO 2 emissions. However, hydroelectric systems produce environmental and social impacts locally that require mitigative measures. To fulfill its mandate in a sustainable development context, Hydro-Quebec has adopted methods such as integrated resource planning, the assessment of externalities, multi criteria decision tools and public participations

It has been acknowledged that river morphology and hydrology have been intensively altered due to the anthropic demands in floodplain land use and management, flood protection, promotion of navigability or energy production. Rivers were transformed in water highways, having lost contact with their surrounding floodplain as well as the plethora of ecological processes and occupants once thriving in these ecotonal zones. The identification of this emerging threat of morphological and hydrological alteration on ecological integrity adds further complexity in the exploitation of hydrosystem resources. These resources are heavily coveted and guarded by different lobbies each having strategic views on future project development. Stakeholders may want to promote hydro-electricity, ecologists a natural reserve, communes may wish to have an increased flood protection and leisure promoters a nautical center. As a result, the proposition of a river development project is certain to face opposition of one party or the other. The motivations of this dissertation are anchored in this context, where various and sometimes conflicting potentials for hydrosystem exploitation remain. This works aims at contributing scientifically to an innovative approach at the conception phase of a multi-purpose river development project by developing the ecological module to be implemented in the general project's optimizer. The SYNERGIE project hypothesis is that it should be possible to identify a synergetic pattern joining the interests of ecological integrity, flood safety, energy production and leisure development. Such a multi-objective river development project would stand more chance of acceptance. This dissertation focuses on the ecological aspects of such a river development project and an application on the regulated Swiss Upper Rhone River.

Carbon emission from global hydroelectric reservoirs revisited.
Li, Siyue; Zhang, Quanfa
2014-12-01
Substantial greenhouse gas (GHG) emissions from hydropower reservoirs have been of great concerns recently, yet the significant carbon emitters of drawdown area and reservoir downstream (including spillways and turbines as well as river reaches below dams) have not been included in global carbon budget. Here, we revisit GHG emission from hydropower reservoirs by considering reservoir surface area, drawdown zone and reservoir downstream. Our estimates demonstrate around 301.3 Tg carbon dioxide (CO2)/year and 18.7 Tg methane (CH4)/year from global hydroelectric reservoirs, which are much higher than recent observations. The sum of drawdown and downstream emission, which is generally overlooked, represents 42 % CO2 and 67 % CH4 of the total emissions from hydropower reservoirs. Accordingly, the global average emissions from hydropower are estimated to be 92 g CO2/kWh and 5.7 g CH4/kWh. Nonetheless, global hydroelectricity could currently reduce approximate 2,351 Tg CO2eq/year with respect to fuel fossil plant alternative. The new findings show a substantial revision of carbon emission from the global hydropower reservoirs.

Most energy generation globally is fueled by coal and oil, raising concerns about greenhouse gas emissions. Hydroelectric reservoirs are anthropogenic aquatic systems that occur across a wide geographical extent, and, in addition to their importance for energy production, they have the potential to release two important greenhouse gases (GHGs), carbon dioxide and methane. We report results from an extensive study of eight hydroelectric reservoirs located in central and southeastern tropical Brazil. In the Brazilian dry tropical biome reservoirs, emissions (in tons of CO 2 Eq. per MW h) varied from 0.01 to 0.55, and decreased with reservoir age. Total emissions were higher in the reservoir lake when compared to the river downstream the dam; however, emissions per unit area, in the first kilometer of the river after the dam, were higher than that in the reservoir. The results showed, despite higher carbon emissions per energy production in the youngest reservoirs, lower emission from hydroelectric reservoirs from the studied region in relation to thermo electrical supply, fueled by coal or fossil fuel. The ratio emission of GHG per MWh produced is an important parameter in evaluating the service provided by hydroelectric reservoir and for energy planning policies. - Highlights: ► Hydroelectric reservoirs construction is growing worldwide. ► The effect of hydropower reservoir in the carbon cycle is dependent on environment characteristics. ► Carbon emissions per energy production are higher in the youngest tropical savannah reservoirs. ► Methane emissions decrease with reservoir age in tropical savannah reservoirs. ► In general, the effect of hydropower in the carbon cycle is lower than other energy sources

Hydroelectric power and hydroelectric power plants. V. 1
International Nuclear Information System (INIS)
1991-06-01
Following the oil crises of 1973 and 1979, there was renewed and justifiable interest in small hydroelectric plants. The maximum power of these plants rarely exceeds 10 MW, and their development will surely increase in the coming decades. Hydraulic power is a national renewable resource, unaffected by geopolitical problems, and above all, non polluting. Many countries with their own hydraulic resources in both the industrialized and the developing world have expressed needs for the development of small hydroelectric plants. Hidroenergia 91 Conference is the opportunity to take stock of knowledge gained in the vast field of small hydroelectric plants. The meeting is divided into four subjects: 1 methods for decision aid; 2 environmental impact and accompanying answers; 3 national development policy; 4 world market and international cooperation. This meeting contains 75 papers, 8 papers are in the INIS scope and 72 papers are in the ENERGY DATA BASE scope

Goulet, R.
1993-01-01
The Great Whale hydroelectric complex in northern Quebec will require diversion of the Little Whale River, involving construction of dams 40 m and 30 m high and a canal 600 m long. The main mode of access to the construction sites will be a winter road, supplemented by an airfield designed for large-capacity aircraft. The method used by Hydro-Quebec in its environmental assessment of the winter road project is described. This method comprises five steps: delimitation of the study zone; establishment of a road corridor of choice by successively eliminating territory according to given constraints; description of the physical and biological environment; determination and optimization of the road route; and evaluation of potential impacts, along with establishment of measures to mitigate those impacts. The optimal routing is determined on the basis of criteria such as the presence of permafrost, the nature of the soils, avoidance of slopes steeper than 10%, and the depth and width of ice crossings

Columbia River System Operation Review final environmental impact statement. Appendix I: Power
International Nuclear Information System (INIS)
1995-11-01
The System Operation Review (SOR) is a study and environmental compliance process being used by the three Federal agencies to analyze future operations of the system and river use issues. The goal of the SOR is to achieve a coordinated system operation strategy for the river that better meets the needs of all river users. This technical appendix addresses only the effects of alternative system operating strategies for managing the Columbia River system. This appendix discusses the work performed by the SOR Power Work Group. The Power Work Group (PWG) had several major responsibilities: first, to determine the effects of each of the various system operating strategies (SOS) on the Northwest regional power system; second, given these effects, to determine what, if any, actions are required to meet forecasted regional energy consumption; and finally, to estimate the cost for serving the forecasted regional energy consumption. The Northwest regional power system consists of Federal and non-Federal hydroelectric power projects (hydropower or hydro projects) on the main stem of the Columbia and Snake Rivers, numerous smaller hydro projects on other river reaches, and a number of thermal plants (coal, nuclear and combustion turbines)

This paper reports on the problems that hydroelectric plants have regarding fish populations. The utilities that operate these plants are finding that accommodating migrating fish presents unique engineering challenges, not the least of which involves designing and building systems to protect fish species whose migratory behavior remains something of a mystery. Where such systems cannot be built, the status of hydroelectric dams may be in doubt, as is now the case with several dams in the United States. A further twist in some regions in the possibility that certain migratory fish will be declared threatened or endangered-a development that could wreak havoc on the hydroelectric energy supply in those regions

This paper described a web-served public access archive of down-scaled climate projections developed as a tool for water managers of river and hydropower systems. The archive provided access to climate projection data at basin-relevant resolution and included an extensive compilation of down-scale climate projects designed to support risk-based adaptation planning. Downscaled translations of 112 contemporary climate projections produced using the World Climate Research Program's coupled model intercomparison project were also included. Datasets for the coupled model included temperature and precipitation, monthly time-steps, and geographic coverage for the United States and portions of Mexico and Canada. It was concluded that the archive will be used to develop risk-based studies on shifts in seasonal patterns, changes in mean annual runoff, and associated responses in water resources and hydroelectric power management. Case studies demonstrating reclamation applications of archive content and potential applications for hydroelectric power production impacts were included. tabs., figs

Installation of a Low Flow Unit at the Abiquiu Hydroelectric Facility
Energy Technology Data Exchange (ETDEWEB)
Jack Q. Richardson
2012-06-28
Final Technical Report for the Recovery Act Project for the Installation of a Low Flow Unit at the Abiquiu Hydroelectric Facility. The Abiquiu hydroelectric facility existed with two each 6.9 MW vertical flow Francis turbine-generators. This project installed a new 3.1 MW horizontal flow low flow turbine-generator. The total plant flow range to capture energy and generate power increased from between 250 and 1,300 cfs to between 75 and 1,550 cfs. Fifty full time equivalent (FTE) construction jobs were created for this project - 50% (or 25 FTE) were credited to ARRA funding due to the ARRA 50% project cost match. The Abiquiu facility has increased capacity, increased efficiency and provides for an improved aquatic environment owing to installed dissolved oxygen capabilities during traditional low flow periods in the Rio Chama. A new powerhouse addition was constructed to house the new turbine-generator equipment.

This report describes research conducted by the Pacific Northwest National Laboratory for the Bonneville Power Administration (BPA) as part of the Fish and Wildlife Program directed by the Northwest Power and Conservation Council. The study evaluated the restoration potential of Snake River fall Chinook salmon spawning habitat within the impounded lower Snake River. The objective of the research was to determine if hydroelectric dam operations could be modified, within existing system constraints (e.g., minimum to normal pool levels; without partial removal of a dam structure), to increase the amount of available fall Chinook salmon spawning habitat in the lower Snake River. Empirical and modeled physical habitat data were used to compare potential fall Chinook salmon spawning habitat in the Snake River, under current and modified dam operations, with the analogous physical characteristics of an existing fall Chinook salmon spawning area in the Columbia River. The two Snake River study areas included the Ice Harbor Dam tailrace downstream to the Highway 12 bridge and the Lower Granite Dam tailrace downstream approximately 12 river kilometers. These areas represent tailwater habitat (i.e., riverine segments extending from a dam downstream to the backwater influence from the next dam downstream). We used a reference site, indicative of current fall Chinook salmon spawning areas in tailwater habitat, against which to compare the physical characteristics of each study site. The reference site for tailwater habitats was the section extending downstream from the Wanapum Dam tailrace on the Columbia River. Fall Chinook salmon spawning habitat use data, including water depth, velocity, substrate size and channelbed slope, from the Wanapum reference area were used to define spawning habitat suitability based on these variables. Fall Chinook salmon spawning habitat suitability of the Snake River study areas was estimated by applying the Wanapum reference reach habitat

In this paper I use a stochastic distance frontier approach to assess the performance of Chile's hydroelectric industry, which operates within a regulatory framework designed to achieve a competitive outcome. An occasionally free input, water, is the sole energy input. The econometric analysis indicates substantial technical and allocative inefficiencies as well as volatile productivity scores, due presumably to the volatility of the energy input. Some allocative inefficiencies have diminished dramatically as the time under deregulation has grown. The Lerner index suggests that firms in the industry enjoy some degree of market power, reflected by prices that exceed marginal costs. This market power is consistent with operation within a centralized dispatch center, as predicted by a strategic bidding model. I also find that run-of-river plants exhibit increasing returns to scale, while plants relying on dams show slightly diminishing returns. The shadow marginal cost for run-of-river plants is found to be close to zero. Substantial cost savings could be realized if firms in Chile's hydro-electric generation industry were to operate efficiently.

Yakima Basin Fish Passage Project, Phase 2
International Nuclear Information System (INIS)
1991-08-01
Implementation of the Yakima Basin Fish Passage Project -- Phase 2 would significantly improve the production of anadromous fish in the Yakima River system. The project would provide offsite mitigation and help to compensate for lower Columbia River hydroelectric fishery losses. The Phase 2 screens would allow greater numbers of juvenile anadromous fish to survive. As a consequence, there would be higher returns of adult salmon and steelhead to the Yakima River. The proposed action would play an integral part in the overall Yakima River anadromous fish enhancement program (fish passage improvement, habitat enhancement, hatchery production increases, and harvest management). These would be environmental benefits associated with implementation of the Fish Passage and Protective Facilities Phase 2 Project. Based on the evaluation presented in this assessment, there would be no significant adverse environmental impacts if the proposed action was carried forward. No significant adverse environmental effects have been identified from construction and operation of the Yakima Phase 2 fish passage project. Proper design and implementation of the project will ensure no adverse effects will occur. Based on the information in this environmental analysis, BPA's and Reclamation's proposal to construct these facilities does not constitute a major Federal action that could significantly affect the quality of the human environment. 8 refs., 4 figs., 6 tabs

South Asia river flow projections and their implications for water resources

benchmark for comparison against the downscaled GCMs. On the basis that these simulations are among the highest resolution climate simulations available we examine how useful they are for understanding the changes in water resources for the South Asia region. In general the downscaled GCMs capture the seasonality of the river flows, with timing of maximum river flows broadly matching the available observations and the downscaled ERA-Interim simulation. Typically the RCM simulations over-estimate the maximum river flows compared to the observations probably due to a positive rainfall bias and a lack of abstraction in the model although comparison with the downscaled ERA-Interim simulation is more mixed with only a couple of the gauges showing a bias compared with the downscaled GCM runs. The simulations suggest an increasing trend in annual mean river flows for some of the river gauges in this analysis, in some cases almost doubling by the end of the century; this trend is generally masked by the large annual variability of river flows for this region. The future seasonality of river flows does not change with the future maximum river flow rates still occuring during the ASM period, with a magnitude in some cases, greater than the present day natural variability. Increases in river flow during peak flow periods means additional water resource for irrigation, the largest usage of water in this region, but also has implications in terms of inundation risk. Low flow rates also increase which is likely to be important at times of the year when water is historically more scarce. However these projected increases in resource from rivers could be more than countered by changes in demand due to reductions in the quantity and quality of water available from groundwater, increases in domestic use due to a rising population or expansion of other industries such as hydro-electric power generation.

A pilot study was conducted to estimate survival of hatchery-reared yearling chinook salmon through dams and reservoirs on the Snake River. The goals of the study were to: (1) field test and evaluate the Single-Release, Modified-Single-Release, and Paired-Release Models for the estimation of survival probabilities through sections of a river and hydroelectric projects; (2) identify operational and logistical constraints to the execution of these models; and (3) determine the usefulness of the models in providing estimates of survival probabilities. Field testing indicated that the numbers of hatchery-reared yearling chinook salmon needed for accurate survival estimates could be collected at different areas with available gear and methods. For the primary evaluation, seven replicates of 830 to 1,442 hatchery-reared yearling chinook salmon were purse-seined from Lower Granite Reservoir, PIT tagged, and released near Nisqually John boat landing (River Kilometer 726). Secondary releases of PIT-tagged smolts were made at Lower Granite Dam to estimate survival of fish passing through turbines and after detection in the bypass system. Similar secondary releases were made at Little Goose Dam, but with additional releases through the spillway. Based on the success of the 1993 pilot study, the authors believe that the Single-Release and Paired-Release Models will provide accurate estimates of juvenile salmonid passage survival for individual river sections, reservoirs, and hydroelectric projects in the Columbia and Snake Rivers.

The hydroelectric power market in the United States
International Nuclear Information System (INIS)
2002-01-01
The second-largest producer of hydroelectric power in the world is the United States, right after Canada. In the United States, 7.1 per cent of net electricity generation was attributed to hydroelectric power in 2000, which totalled 269 terawatt hours (TWh). Aging facilities, outdated technology in some facilities, a cumbersome licensing process, and increasing environmental demands from interest groups for the preservation of river systems and surrounding wildlife challenge the industry. Pacific Coast states, especially California, were faced with electric power shortages during the summer of 2001, due to low market prices, high power usage among consumers and drought. The problems with the deregulation of the electricity market were brought to light by these shortages. Legislation to restructure the electric power industry in 25 states had not been enacted as of January 2002. The purchase of more power from both Canada and the Mexico is being considered by the government of the United States, as is the creation of a national power grid to allow for power transmission throughout the country. The Canada-United States energy trade might be affected by such a move, and result in project construction opportunities for Canadian companies. Renewable energy sources must be responsible for the generation of 10 per cent of power generation levels by 2020, on a gradual basis as mandated by law. By 2005, New York City must purchase 10 per cent of its power from renewable energy sources, reaching 20 per cent by 2010. The repair and replacement of aging dam equipment, the development of advanced turbine technology to protect fish stocks and water quality, dam removal, the construction of power lines are all opportunities open to Canadian companies. 60 refs., 5 tabs

None,
1980-05-01
The legal and institutional obstacles to the development of small-scale hydroelectric energy at the state level are examined. The introductory section examines the dual regulatory system from the standpoint of the appropriate legal doctrine, the law of pre-emption, application of the law to the case of hydroelectric development, and concludes with an inquiry into the practical use of the doctrine by the FERC. Additional sections cover acquisition; liability; Department for Natural Resources and Environmental Protection; energy utilities; local regulations; incidental impacts; financial considerations; and sources of information. In Kentucky, many of the impacts have not been implemented with regard to small-scale hydroelectric energy, since in Kentucky most electricity is coal-generated and any hydroelectric power that does exist, is derived from TVA or the Army Corp of Engineer projects.

Climate change is likely to affect extreme flows as well as average flows. This is an important consideration for hydroelectric power producers. This paper presented the development of an approach to assess the impact of climate changes on seasonal and average annual river flows. The main goal was to investigate how climate change will affect the hydroelectric potential of the Lower Churchill Project using different combinations of emissions scenarios, climate model output and downscaling techniques. The setup and calibration of the numerical hydrological model, WATFLOOD, were performed as preliminary work for the Pinus River basin selected as study basin. Downscaled climate data from the North America change assessment program for both current and future climate periods were analysed. The calibrated model was used to simulate the current and future period streamflow scenarios. The results showed a 13 percent increase in mean annual flows concentrated in the winter and spring seasons.

Development of the Qattara Project, Egypt
International Nuclear Information System (INIS)
1978-01-01
The River Nile, as a huge source of cheap hydroelectric energy, was fully exploited in Egypt upstream of Aswan in 1968 by the construction of the famous Aswan and High Dam Hydroelectric Complex. The growth of demand for electrical power is such that an additional large source of energy is required. The Qattara Project would offer not only an ideal source of low cost power production, but a vital boost for Egypt's national economy. The fundamental idea of the scheme is to channel Mediterranean Sea water into the Qattara Depression, using the difference in levels to produce hydroelectric power. The rate of discharge of sea water into the depression should be equivalent to the rate of evaporation from the lake surface. This situation will arise ten years after starting to fill the lake, when the water has reached a level of 60 m below sea level. The possibility of using PNE to excavate a Mediterranean Sea - Qattara Depression canal was first postulated by the Egyptian Atomic Energy Establishment in 1971. In 1973 a pre-feasibility study was prepared, based on preliminary site investigations performed during the period 1964-1965, namely geological and cartographic surveys, as well as on comparative economic evaluation of various solutions. The study showed clearly that the project including both base-load and peak-load hydroelectric power stations and using nuclear excavation of a canal between the sea and the depression offers a competitive solution for cheap power production. A subsequent feasibility study, which was started in 1975, investigates alternative ways of constructing the canal/tunnel system, using conventional tunnelling and PNE. For the nuclear solution, two cases are considered, one using unlimited yields and another with 150 kt maximum yield. A preliminary assessment of the effects of the explosion and costs of the nuclear component of the project are given. (author)

Biodiversity loss is accelerating rapidly in response to increasing human influence on the Earth's natural ecosystems. One way to overcome this problem is by focusing on places of human interest and monitoring the changes and impacts on the biodiversity. This study was conducted at six sites within the influence area of the Santo Antônio Hydroelectric Power Plant in the margins of the Madeira River in Rondônia State. The sites cover a latitudinal gradient of approximately 100 km in the Brazilian Amazon Basin. The sampling design included six sampling modules with six plots (transects) each, totaling 30 sampling plots. The transects were distributed with 0 km, 0.5 km, 1 km, 2 km, 3 km and 4 km, measured perpendicularly from the river margin towards the interior of the forest. For sampling the ground-dwelling ants, the study used the ALL (ants of the leaf litter) protocol, which is standardized globally in the inventories of ant fauna. For the purpose of impact indicators, the first two campaigns (September 2011 to November 2011) were carried out in the pre-filling period, while campaigns 3 to 10 (February 2012 to November 2014) were carried out during and after the filling of the hydroelectric reservoir. A total of 253 events with a total of 9,165 occurrences were accounted during the monitoring. The ants were distributed in 10 subfamilies, 68 genera and 324 species/morphospecies. The impact on ant biodiversity during the periods before and after filling was measured by ecological indicators and by the presence and absence of some species/morphospecies. This is the first study, as far as we know, including taxonomic and ecological treatment to monitor the impact of a hydroelectric power plant on ant fauna. Until recently, most studies conducted on hydroelectric plants, located in the Amazon Basin, were carried out after the implementation of dams in order to assess their impacts on the environment and biodiversity (Benchimol and Peres 2015, Latrubesse et al. 2017

Due to rising energy demands and abundant untapped potential, hydropower projects are rapidly increasing in the Neotropics. This is especially true in the wet and rugged Andean Amazon, where regional governments are prioritizing new hydroelectric dams as the centerpiece of long-term energy plans. However, the current planning for hydropower lacks adequate regional and basin-scale assessment of potential ecological impacts. This lack of strategic planning is particularly problematic given the intimate link between the Andes and Amazonian flood plain, together one of the most species rich zones on Earth. We examined the potential ecological impacts, in terms of river connectivity and forest loss, of the planned proliferation of hydroelectric dams across all Andean tributaries of the Amazon River. Considering data on the full portfolios of existing and planned dams, along with data on roads and transmission line systems, we developed a new conceptual framework to estimate the relative impacts of all planned dams. There are plans for 151 new dams greater than 2 MW over the next 20 years, more than a 300% increase. These dams would include five of the six major Andean tributaries of the Amazon. Our ecological impact analysis classified 47% of the potential new dams as high impact and just 19% as low impact. Sixty percent of the dams would cause the first major break in connectivity between protected Andean headwaters and the lowland Amazon. More than 80% would drive deforestation due to new roads, transmission lines, or inundation. We conclude with a discussion of three major policy implications of these findings. 1) There is a critical need for further strategic regional and basin scale evaluation of dams. 2) There is an urgent need for a strategic plan to maintain Andes-Amazon connectivity. 3) Reconsideration of hydropower as a low-impact energy source in the Neotropics.

Using a case-study, inductive, narrative approach, this article explores the history, drivers, benefits, and barriers to the Bakun Hydroelectric Project in East Malaysia. Situated on the island of Borneo, Bakun Dam is a 204 m high concrete face, rock filled dam on the Balui River in the Upper Rajang Basin in the rainforests of Sarawak. Bakun Dam and its affiliated infrastructure could be the single largest and most expensive energy project ever undertaken in Southeast Asia. Based on data collected through site visits, original field research in Sarawak, and more than 80 research interviews, the article begins by teasing out the complex history and drivers behind the Bakun project before identifying a set of potential social, political, and economic benefits the project could deliver. It then delves into six sets of barriers in the technical, economic, political, legal and regulatory, social, and environmental realms. We find that Bakun illustrates how centralized energy megaprojects, while ostensibly championed for reasons of economies of scale and the ability to bring about transformational change in the shortest period of time, often fail to address broader development goals such as fighting energy poverty and improving the livelihoods of the local communities they are supposed to serve. - Highlights: → Bakun Dam is concrete face, rock filled dam on the Balui River in the Upper Rajang Basin in the rainforests of Sarawak. → The project faces technical, economic, political, legal and regulatory, social, and environmental barriers. → We conclude the project will fail to fight energy poverty or improve the livelihoods of local populations.

1994-01-01
An extensive fish sampling and tagging program was conducted on the Snare River, Northwest Territories, in order to collect baseline data on the fish populations in sections of the river altered by hydroelectric projects. Fish populations were sampled from May to July 1977 in five sections of the river that were influenced by development of hydropower at three dams currently on line; 530 tagged fish were also released. The biweekly catch composition in experimental gill nets for each study area and the catch per gill net mesh size are presented for walleye (Stizostedion vitreum), lake trout (Salvelinus namaycush), lake whitefish (Coregonus clupeaformis), lake cisco (Coregonus artedi), northern pike (Esox lucius), white sucker (Catostomus commersoni), and longnose sucker (Catostomus catostomus). Age-specific data on length, weight, age, sex, and maturity are also included. 7 refs., 12 figs., 42 tabs

When the foreseen contribution of our HE installed power to our total installed power and that of our HE energy production to our total energy production for 2005-2020 period is analysed, it is seen that it is foreseen that these contributions are not to be changing at significant levels for the coming 15 years. It has not been possible to explain the fact that 2/3 of our hydroelectric potential, which is independent of foreign countries, is not yet evaluated and the fact that no attempt is made to increase its contribution. This situation should be perceived as an unusual approach in our country.

Pacific Lamprey Research and Restoration Project : Annual Report 2001.
Energy Technology Data Exchange (ETDEWEB)
Close, David A.
2002-11-01
Pacific lamprey (Lampetra tridentata) has significantly declined along the Oregon coast and in the Columbia River Basin (Downey et al. 1993; Close and Jackson 2001). Declines in adults can be partially attributed to hydroelectric dams, which have impeded passage of adult Pacific lamprey in the Columbia and Snake rivers, thus effecting larval recruitment in the basin. Adult pacific lamprey also declined in numbers in the Umatilla River, a tributary of the Columbia River. In addition to hydro power dams in the Columbia River, habitat alterations and chemical treatments have been involved in the collapse of Pacific lamprey populations in the Umatilla River. To initiate the restoration effort, CTUIR began developing a restoration plan in 1998. The goal of the lamprey research and restoration project is to restore natural production of Pacific lampreys in the Umatilla River to self-sustaining and harvestable level. This report is summarizing the studies and restoration efforts concluded in 2001.

Fish screens at hydroelectric diversions
International Nuclear Information System (INIS)
Ott, R.F.
1994-01-01
Preventing downstream migrating fish from entering the turbines at hydroelectric projects is a standard mitigation goal of state and federal fishery management agencies. The object is to minimize the adverse impacts to the fish associated with the exclusion and passage through the bypass water conveyance facilities. In the western United States, most of the fishery management agencies have fish screen design criteria that focus on the approach and transportational velocities, maximum opening dimensions of the screen material, and the cleaning standards. Recently, more attention has been given to fish behavioral traits such as attraction and sustained and darting swimming speed, which has resulted in more attention to the position of the screens to the flow and the length of time the downstream migrants are exposed to the screens. Criteria for length of time of exposure, size and position of bypass, flow and velocities in the bypass entrances, discharge requirements back into the receiving water, and exposure to predation have created unique challenges to the fish screen designer. This paper discusses some of the more recent types of fixed fish screens that are being installed at hydroelectric plants that meet these challenges

1996-01-01
This paper presents an analysis of the past and present situation in hydroelectric power (achievements, rates of commissioning and so on) and the future strategies for the hydroelectric power resource development in the conditions of a free market economy. At present the contribution of hydroelectric power in the Romania's total power balance is about 16,500 GW h/year which represents nearly 28 %. The theoretical hydroelectric power potential of Romania is 75,000 GW h/year while the technical potential, which could actually be developed, is only 40,000 GW h/year. Finally, there are presented the main directions in the hydroelectric power development up to the year 2020. (author) 3 tabs

1996-05-01
As part of a continuing effort to restore anadromous fish populations in the South Fork Clearwater River basin of Idaho, Bonneville Power Administration (BPA) proposes to fund the Lower Red River Meadow Restoration Project (Project). The Project is a cooperative effort with the Idaho Soil and Water Conservation District, Nez Perce National Forest, Idaho Department of Fish and Game (IDFG), and the Nez Perce Tribe of Idaho. The proposed action would allow the sponsors to perform stream bank stabilization, aquatic and riparian habitat improvement activities on IDFG's Red River Management Area and to secure long-term conservation contracts or agreements for conducting streambank and habitat improvement activities with participating private landowners located in the Idaho County, Idaho, study area. This preliminary Environmental Assessment (EA) examines the potential environmental effects of stabilizing the stream channel, restoring juvenile fish rearing habitat and reestablishing a riparian shrub community along the stream

The vertical distribution of net zooplankton in head-water of Krasnoyarsk hydroelectric power station and its horizontal distribution in the tail-water were studied during two years in winter and summer seasons. In order to distinguish living and dead individuals the special staining was used. It was revealed that on average 77% of living plankton pass through high-head dam with deep water scoop to the tailwater. While passing through dam aggregates some individuals of the reservoir plankton are traumatized and die, that results in some increase of portion of dead individuals in the tail water near dam (from 3 to 6%). Alive zooplankton passed through the dam aggregates is eliminated under the Upper Yenisei highly turbulent conditions. There is approximately 10% of it in 32 km from the dam if compare with biomass in 20-40 m layer of reservoir, the portion of dead increases to 11%. The biomass of zooplankton suspended in the water column of the tail-water sometimes increases (till > 1 g/m3) due to large Copepoda Heteroscope borealis, which inhabits near-bottom and near-shore river zones and can be found in the central part of the river during reproductive period. Limnetic zooplankton from the reservoir cannot be considered as important food for planktivores in the tail-water.

In this chapter of the book author deals with the Gabcikovo-Nagymaros Project (GNP). The Gabcikovo part of the hydroelectric power project was based on a combination of flood control, navigational improvements and the production of electric energy. The Gabcikovo Project has not only saved the inundation area with the flood plain ecotopes, but also includes a wide variety of tools for surface and ground water management, and thus also for the management, or optimalization, of the development of agricultural conditions, inundation biotopes, forestry, river branches biotopes, flood management and the flooding of parts of the inundation area, sedimentation and erosion processes, ground and surface water quality, and other environmental effects management. The GNP, as conceived in the 1977 International Czechoslovak-Hungarian Treaty, is located roughly between 1,860 rkm (river kilometer), at Bratislava, and 1,696 rkm, at Nagymaros. The Hungarians unilaterally decided to abandon the construction of Nagyamaros, and to suspend the work to be carried out on the GNP. After the decision, in order to minimize the spread of economic and ecologic damages to ensure flood protection at least on the Hungarian Szikekoez, to exploit the available power potential, and to create conditions necessary for navigation on the Danube, the Government of the Czech and Slovak Federal Republic decided in December 1991, to put nearly ready Gabcikovo part of the system into operation, constructing the necessary technical structures on their own territory and inside of the construction area of the original Project. These technical structures are known as 'Variant C'. 'Variant C' is situated inside the area of the original project, replaces the function of the Dunakiliti weir in Hungary and uses all of the completed structures of the Gabcikovo part of the Project. The geology, Danube, ground water, pre-dam long-term development, changes after putting the Gabcikovo structures into operation, as well

Today's notice announces BPA's proposal to fund land acquisition or acquisition of a conservation easement and a wildlife management plan to protect and enhance wildlife habitat at the Willow Creek Natural Area in Eugene, Oregon. This action would provide partial mitigation for wildlife and wildlife habitat lost by the development of Federal hydroelectric projects in the Willamette River Basin. The project is consistent with BPA's obligations under provisions of the Pacific Northwest Electric Power Planning and Conservation Act of 1980 as outlined by the Northwest Power Planning Council's 1994 Columbia River Basin Fish and Wildlife Program. BPA has prepared an environmental assessment (DOE/EA-1023) evaluating the proposed project. Based on the analysis in the EA, BPA has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment, within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an environmental impact statement (EIS) is not required and BPA is issuing this FONSI

The Umatilla River Basin Anadromous Fish Habitat Enhancement Project continued to identify impacted stream reaches throughout the Umatilla River Basin for habitat improvements during the 2001 project period. Public outreach efforts, biological and physical monitoring, and continued development of a Umatilla Subbasin Watershed Assessment assisted the project in fostering public cooperation, targeting habitat deficiencies and determining habitat recovery measures. Projects continued to be maintained on 49 private properties, one 25-year Non-Exclusive Bureau of Indian Affairs' Easement was secured, six new projects implemented and two existing project areas improved to enhance anadromous fish habitat. New project locations included sites on the mid Umatilla River, upper Umatilla River, Mission Creek, Cottonwood Creek and Buckaroo Creek. New enhancements included: (1) construction of 11,264 feet of fencing between River Mile 43.0 and 46.5 on the Umatilla River, (2) a stream bank stabilization project implemented at approximately River Mile 63.5 Umatilla River to stabilize 330 feet of eroding stream bank and improve instream habitat diversity, included construction of eight root wad revetments and three boulder J-vanes, (3) drilling a 358-foot well for off-stream livestock watering at approximately River Mile 46.0 Umatilla River, (4) installing a 50-foot bottomless arch replacement culvert at approximately River Mile 3.0 Mission Creek, (5) installing a Geoweb stream ford crossing on Mission Creek (6) installing a 22-foot bottomless arch culvert at approximately River Mile 0.5 Cottonwood Creek, and (7) providing fence materials for construction of 21,300 feet of livestock exclusion fencing in the Buckaroo Creek Drainage. An approximate total of 3,800 native willow cuttings and 350 pounds of native grass seed was planted at new upper Umatilla River, Mission Creek and Cottonwood Creek project sites.

In this work, a comparative study on the water quality characteristics of two in-line water reservoirs (artificial lakes) in Aliakmon River (Western Macedonia, Greece) is performed. Polyfytos Reservoir and Ilarion Reservoir were created in 1975 and 2012 respectively, in order to serve the homonymous hydroelectric stations. In young artificial lakes, severe deterioration of water quality may occur; thus, the monitoring and assessment of their water quality characteristics and their statistical interpretation are of great importance. In order to evaluate any temporal or spatial variations and to characterize water quality of these two in-line water reservoirs, water quality data from measurements conducted from 2012 to 2015 were statistically processed and interpreted by using a modified National Sanitation Foundation water quality index (WQI). The water physicochemical characteristics of the two reservoirs were found to be generally within the legislation limits, with relatively small temporal and spatial variations. Although Polyfytos Reservoir showed no significant deviations of its water quality, Ilarion Reservoir exhibited deviations in total Kjeldahl nitrogen, nitrite nitrogen, total suspended solids, and turbidity due to the inundated vegetation decomposition. The conducted measurements and the use of the modified NSFWQI revealed that during the inundation period of Ilarion Reservoir, its water quality was "moderate" and that the deviations were softened through time, leading to "good" water quality during its maturation period. Three years since the creation of Ilarion Reservoir, water quality does not match that of Aliakmon River (feeding water) or that of the stabilized reservoir (Polyfytos Reservoir), whose quality is characterized as "high." The use of a WQI, such as the proposed modified NSFWQI, for evaluating water quality of each sampling site and of an entire water system proved to be a rapid and relatively accurate assessment tool.

Hydroelectricity, an opportunity to grab?
International Nuclear Information System (INIS)
Yergeau, M.
1997-01-01
The deregulation within the electricity sector and the government''s project approval process were discussed. Deregulation was meant to simplify trade while providing consumers with a fair price, quality service and end-product quality. Proposals for large hydroelectric projects, however, must still be authorized by the government. The environmental assessment process for projects involving energy transmission infrastructures is long and complicated. All of Hydro-Quebec''s recent large projects were challenged in court. While energy market players need environmentally credible generating schemes, there appears to be nothing on the horizon to suggest that the approval process is going to be made easier soon. Indeed, there is every reason to believe that recent gains in environmental and social protection will not be sold off to ease the burden on utility companies to prove their case before construction. The choice is between speed and quality in matters of authorization, and while every effort should be made to combine the two, when it comes down to a choice, there should be no question as to what must be preserved. 2 figs

This paper develops a geopolitical analysis of dams and hydroelectric plants in the Brazilian Amazon since the mid-2000's. The implementation of these projects has provoked tensions within the federal government under the presidency of the Workers' Party and accelerated the erosion of the ideological and political platform called 'socio-environmentalism', a situation that has led to the break-up of the coalition leading to the political crisis of 2016 and the impeachment of President Dilma Rousseff. From a regional point of view, the dispute occurred in very different terms in the case of the Madeira hydroelectric power stations (Santo Antonio and Jirau in Rondonia) and in the case of the Xingu dam (Belo Monte in Para), worldwide covered by the media

Impacts of hydroelectric dams on alluvial riparian plant communities in Eastern Brazilian Amazonian.
Ferreira, Leandro Valle; Cunha, Denise A; Chaves, Priscilla P; Matos, Darley C L; Parolin, Pia
2013-09-01
The major rivers of the Amazon River basin and their biota are threatened by the planned construction of large hydroelectric dams that are expected to have strong impacts on floodplain plant communities. The present study presents forest inventories from three floodplain sites colonized by alluvial riparian vegetation in the Tapajós, Xingu and Tocantins River basins in eastern Amazonian. Results indicate that tree species of the highly specialized alluvial riparian vegetation are clearly distinct among the three river basins, although they are not very distinct from each other and environmental constraints are very similar. With only 6 of 74 species occurring in all three inventories, most tree and shrub species are restricted to only one of the rivers, indicating a high degree of local distribution. Different species occupy similar environmental niches, making these fragile riparian formations highly valuable. Conservation plans must consider species complementarily when decisions are made on where to place floodplain forest conservation units to avoid the irreversible loss of unique alluvial riparian vegetation biodiversity.

Kesling, Jason; Abel, Chad; Schwabe, Laurence
2009-01-01
In 1998, the Burns Paiute Tribe (BPT) submitted a proposal to Bonneville Power Administration (BPA) for the acquisition of the Malheur River Wildlife Mitigation Project (Project). The proposed mitigation site was for the Denny Jones Ranch and included Bureau of Land Management (BLM) and Oregon Division of State Lands (DSL) leases and grazing allotments. The Project approval process and acquisition negotiations continued for several years until the BPT and BPA entered into a Memorandum of Agreement, which allowed for purchase of the Project in November 2000. The 31,781 acre Project is located seven miles east of Juntura, Oregon and is adjacent to the Malheur River (Figure 1). Six thousand three hundred eighty-five acres are deeded to BPT, 4,154 acres are leased from DSL, and 21,242 acres are leased from BLM (Figure 2). In total 11 grazing allotments are leased between the two agencies. Deeded land stretches for seven miles along the Malheur River. It is the largest private landholding on the river between Riverside and Harper, Oregon. Approximately 938 acres of senior water rights are included with the Ranch. The Project is comprised of meadow, wetland, riparian and shrub-steppe habitats. The BLM grazing allotment, located south of the ranch, is largely shrub-steppe habitat punctuated by springs and seeps. Hunter Creek, a perennial stream, flows through both private and BLM lands. Similarly, the DSL grazing allotment, which lies north of the Ranch, is predominantly shrub/juniper steppe habitat with springs and seeps dispersed throughout the upper end of draws (Figure 2).

1995-11-01
Since the 1930's, the Columbia River has been harnessed for the benefit of the Northwest and the nation. Federal agencies have built 30 major dams on the river and its tributaries. Dozens of non-Federal projects have been developed as well. The dams provide flood control, irrigation, navigation, hydro-electric power generation, recreation, fish and wildlife, and streamflows for wildlife, anadromous fish, resident fish, and water quality. This is Appendix F of the Environmental Impact Statement for the Columbia River System, focusing on irrigation issues and concerns arrising from the Irrigation and Mitigation of impacts (M ampersand I) working Group of the SOR process. Major subheadings include the following: Scope and process of irrigation/M ampersand I studies; Irrigation/M ampersand I in the Columbia Basin Today including overview, irrigated acreage and water rights, Irrigation and M ampersand I issues basin-wide and at specific locations; and the analysis of impacts and alternative for the Environmental Impact Statement

Pacific Lamprey Research and Restoration Project, Annual Report 2002.
Energy Technology Data Exchange (ETDEWEB)

2003-07-01
Pacific lamprey (Lampetra tridentata) has significantly declined along the Oregon coast and in the Columbia River Basin (Downey et al. 1993, Close and Jackson 2001). Declines in adults can be partially attributed to hydroelectric dams, which have impeded passage of adult Pacific lamprey in the Columbia and Snake rivers (Moser et al. 2002), thus effecting larval recruitment in the basin (Moser and Close in press). Adult Pacific lamprey also declined in numbers in the Umatilla River, a tributary of the Columbia River (Close and Jackson 2001). In addition to hydro power dams in the Columbia River, habitat alterations and chemical treatments have been involved in the collapse of Pacific lamprey populations in the Umatilla River (Close 1999). To initiate the restoration effort, CTUIR began developing a restoration plan in 1998. The goal of the lamprey research and restoration project is to restore natural production of Pacific lampreys in the Umatilla River to self-sustaining and harvestable level. This report is summarizing the studies and restoration efforts concluded in 2002.

Greenhouse gas emissions from hydroelectric reservoirs
International Nuclear Information System (INIS)
Rosa, L.P.; Schaeffer, R.
1994-01-01
In a recent paper, Rudd et al. have suggested that, per unit of electrical energy produced, greenhouse-gas emissions from some hydroelectric reservoirs in northern Canada may be comparable to emissions from fossil-fuelled power plants. The purpose of this comment is to elaborate these issues further so as to understand the potential contribution of hydroelectric reservoirs to the greenhouse effect. More than focusing on the total budget of carbon emissions (be they in the form of CH 4 or be they in the form of CO 2 ), this requires an evaluation of the accumulated greenhouse effect of gas emissions from hydroelectric reservoirs and fossil-fuelled power plants. Two issues will be considered: (a) global warming potential (GWP) for CH 4 ; and (b) how greenhouse-gas emissions from hydroelectric power plants stand against emissions from fossil-fuelled power plants with respect to global warming

The Umatilla Basin Anadromous Fish Habitat Enhancement Project targets the improvement of water quality and restoration of riparian areas, holding, spawning and rearing habitats of steelhead, spring and fall chinook and coho salmon. The project focused on implementing cooperative instream and riparian habitat improvements on private lands on the Umatilla Indian Reservation from April 1, 1988 to March 31, 1992. These efforts resulted in enhancement of the lower 1/4 mile of Boston Canyon Creek, the lower 4 river miles of Meacham Creek and 3.2 river miles of the Umatilla River in the vicinity of Gibbon, Oregon. In 1993, the project shifted emphasis to a comprehensive watershed approach, consistent with other basin efforts, and began to identify upland and riparian watershed-wide causative factors impacting fisheries habitat and natural fisheries production capabilities throughout the Umatilla River Watershed. During the 1994--95 project period, a one river mile demonstration project was implemented on two privately owned properties on Wildhorse Creek. This was the first watershed improvement project to be implemented by the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) off of the Reservation

For the purpose of solving the water-supply and energy-related problems of the city of Skopje, the need has arisen to construct the 'Skopsko Pole' hydro system. The 'Skopsko Pole' hydro system consists of the power plants 'Kozjak', 'SvetaPetka' and 'Matka'. It is envisioned to use the watercourse of the Treska River and has been envisaged as a multipurpose system, that is, as an anti-flood system, system for irrigation of agricultural land and an electricity producer. Certainly, the meeting of the aforementioned needs will depend on the hydrological potential of the Treska River, which is why an exact and detailed review of the hydrological potential of the Treska River is of vital importance. It is a complex task to determine the optimal work of the hydroelectric power plants built along the same river, even if this is about the so-called run-of-the-water hydroelectric power plants, given the different interests of the water consumers of the same watercourse. This problem will become more complicated if one or more (that is, all) hydroelectric power plants have their own accumulative pools. In this case, the question arises of how the waters of each of the accumulations should be used. During this, we need to bear in mind the fact that every release of water from each of the accumulations alters the elevation points of all the hydroelectric power plants on the same watercourse and thus affects their production and eventually the benefit of their work. With the restructuring of the electric energy systems in different countries over the past 20 years, the vertically integrated power plants have been converted into horizontally integrated ones. In many cases, it is different companies that are the electricity producers, the high-voltage electricity transmitters, and the medium- and low-voltage electricity distributors. Some of these companies are private companies, whereas others are state-owned. Such diverse ownership of the power plants, which are by default

The U.S. Geological Survey (USGS) and the Washington Department of Fish and Wildlife (WDFW) have been working with the Public Utility District No. 2 of Grant County, Washington (Grant PUD), to increase their understanding of predator-prey interactions in the Priest Rapids Hydroelectric Project (PRP), Columbia River, Washington. For this study, the PRP is defined as the area approximately 6 kilometers upstream of Wanapum Dam to the Priest Rapids Dam tailrace, 397.1 miles from the mouth of the Columbia River. Past year’s low survival numbers of juvenile steelhead (Oncorhynchus mykiss) through Wanapum and Priest Rapids Dams has prompted Grant PUD, on behalf of the Priest Rapids Coordinating Committee, to focus research efforts on steelhead migration and potential causal mechanisms for low survival. Steelhead passage survival in 2009 was estimated at 0.944 through the Wanapum Development (dam and reservoir) and 0.881 through the Priest Rapids Development and for 2010, steelhead survival was 0.855 for Wanapum Development and 0.904 for Priest Rapids Development. The USGS and WDFW implemented field collection efforts in 2011 for northern pikeminnow (Ptychocheilus oregonensis), smallmouth bass (Micropterus dolomieu), and walleye (Sander vitreus, formerly Stizostedion vitreum) and their diets in the PRP. For predator indexing, we collected 948 northern pikeminnow, 237 smallmouth bass, 18 walleye, and two largemouth bass (Micropterus salmoides). The intent of this study was to provide standardized predation indices within individual reaches of the PRP to discern spatial variability in predation patterns. Furthermore, the results of the 2011 study were compared to results of a concurrent steelhead survival study. Our results do not indicate excessively high predation of Oncorhynchus spp. occurring by northern pikeminnow or smallmouth bass in any particular reach throughout the study area. Although we found Oncorhynchus spp. in the predator diets, the relative

The hydroelectric resources of the Amazon region are considered a competitive alternative despite the structural problems they entail. Concerning the latter, plans to build large-scale dams in the region have drawn criticism mainly on account of the loss of forest cover in areas flooded by dam reservoirs and the conflicts concerning the relocation of indigenous and riverside communities in the region. This study seeks to contribute to better understanding of the environmental issue in the Amazon by focusing attention on the downstream effects of dams, which have large-scale, hitherto neglected ecological repercussions. The impact of dams extends well beyond the area surrounding the artificial lakes they create, harming rich Amazon wetland ecosystems. The morphology of dammed rivers changes in response to new inputs of energy and matter, which may in turn destroy certain biotypes. This is a remote-sensing-based case study of the Tucurui hydroelectric scheme in the Amazon state of Para. Attention is drawn to the need to take into account effects on alluvial rivers downstream from hydroelectric power plants when it comes to making planning decisions, as part of a sustainable energy policy.

This report presents the results of an environmental study carried out in the Qingua/Tunugliarfik Fiord area north of Narssarssuaq in July-October, 1982. The field work in the area included hydrographic investigations in the Tunugliarfik Fiord, fishery investigations in the Qingua river and a survey of the area likely to be affected by a hydro-electric plant. Information on commercial and sport fishing, hunting, sheep-farming, tourism, and conservation interests was also collected. The hydrographic investigations have shown that the inner part of Tunugliarfik is dominated by the estuarine circulation in the upper layer clearly influenced by the Qoroq Fiord. The lower 5 km of the river contain a large population of arctic char. The size of the migrating stock, i.e. excluding young and residual fish, is estimated at 10.000 - 20.000 fish. A series of waterfalls in the end of the Qingua valley constrains migrating fish to the lower river area. Beyond the falls two separate populations of stream-resident arctic char are found. Another non-migrant population is found in the Nordbo/Storesoe area. The arctic char fishery is locally of great importance. The fishery, which is carried out by use of gill net, is particularly extensive in the inner part of the Tunugliarfik Fiord. The Qiangua valley is also a popular site for anglers coming to the area by a daily boat from the hotel in Narssarssuaq. Besides char, great quantities of Greenland cod and Greenland halibut are caught in the fiord. The major part of the catch is consumed locally.

Many Baltic salmon rivers have lost their natural juvenile production due to human activities blocking or reducing access to their spawning grounds, e.g. damming, power generation, partial hinders, etc.. One such hindrance is a hydroelectric complex located in the lower reaches of River Umeaelven in northern Sweden. Water from the forbay created by the dam Norrfors is directed to the Stornorrfors power-station. At times, 100 per cent of the river is directed to the power-station. Water from the power-station then flows via a tunnel and outlet channel to the river. From the point of the tunnel's discharge into the river, the old river bed acts as a bypass channel directing migrating adult fish to a fish ladder located at the base of the dam. In this study, the effect that an additional turbine, that was installed at the power-station in 1986, had on fish passage run-time was examined. Changes in run-time were compared for two periods 1974-1985 and 1986-1995. In 1997, 55 wild and 25 hatchery salmon were captured in the Umeaelven estuary, radio tagged with uniquely coded tags, and tracked upstream. Both manual and automatic loggers were used to locate fish daily. The main findings show that only 26 per cent of the wild salmon and none of the hatchery salmon found the fish ladder. It is suggested that the salmon followed the main water discharge from the power-station outlet and are thus directed away from the entrance to the bypass channel leading to the fish ladder. Salmon respond by moving upstream or downstream depending on the current flow regimes. The bypass channel consists of partial hinders that may explain why it takes on average 52 days for the salmon to migrate 32 km from the estuary to the fish ladder. Adding a fourth turbine at the power-station did not appear to have changed the timing of the migration or the seasonal distribution of the migrating wild salmon through the fish ladder. There was no significant effect of the fourth turbine on the duration

This study aimed to evaluate the contribution of anthropogenic pollution in hydroelectric reservoirs through a case study of the Sao Simao Hydropower. The literature relates the problem of eutrophication with the addition of nutrients (nitrogen and phosphorus) in excess, resulting in water pollution. Through data for both tributary rivers and the reservoir, it was found that the Sao Simao dam presents a framework for eutrophication. We made an analysis to see which tributary rivers were the main sources of nutrients released into the waters of the reservoir and a survey of possible human activities that are contributing to the intake of nutrients in these tributaries.

Project SHARE Sustainable Hydropower in Alpine Rivers Ecosystems
Mammoliti Mochet, Andrea
2010-05-01
SHARE - Sustainable Hydropower in Alpine Rivers Ecosystems is a running project early approved and co funded by the European regional development fund in the context of the European Territorial Cooperation Alpine Space programme 2007 - 2013: the project is formally ongoing from August 2009 and it will end July 2012. Hydropower is the most important renewable resource for electricity production in alpine areas: it has advantages for the global CO2 balance but creates serious environmental impacts. RES-e Directives require renewable electricity enhance but, at the same time, the Water Framework Directive obliges member States to reach or maintain a water bodies "good" ecological status, intrinsically limiting the hydropower exploitation. Administrators daily face an increasing demand of water abstraction but lack reliable tools to rigorously evaluate their effects on mountain rivers and the social and economical outputs on longer time scale. The project intends to develop, test and promote a decision support system to merge on an unprejudiced base, river ecosystems and hydropower requirements. This approach will be led using existing scientific tools, adjustable to transnational, national and local normative and carried on by permanent panel of administrators and stakeholders. Scientific knowledge related to HP & river management will be "translated" by the communication tools and spent as a concrete added value to build a decision support system. In particular, the Multicriteria Analysis (MCA) will be applied to assess different management alternatives where a single-criterion approach (such as cost-benefit analysis) falls short, especially where environmental, technical, economic and social criteria can't be quantified by monetary values. All the existing monitoring databases will be used and harmonized with new information collected during the Pilot case studies. At the same time, all information collected will be available to end users and actors of related

Connectivity is one of the most important characteristics of a river, which is derived from the natural water cycle and determine the renewability of river water. The water conservancy project can change the connectivity of natural river networks, and directly threaten the health and stability of the river ecosystem. Based on the method of Dendritic Connectivity Index (DCI), the impacts from sluices and dams on the connectivity of river network are deeply discussed herein. DCI quantitatively evaluate the connectivity of river networks based on the number of water conservancy facilities, the connectivity of fish and geographical location. The results show that the number of water conservancy facilities and their location in the river basin have a great influence on the connectivity of the river network. With the increase of the number of sluices and dams, DCI is decreasing gradually, but its decreasing range is becoming smaller and smaller. The dam located in the middle of the river network cuts the upper and lower parts of the whole river network, and destroys the connectivity of the river network more seriously. Therefore, this method can be widely applied to the comparison of different alternatives during planning of river basins and then provide a reference for the site selection and design of the water conservancy project and facility concerned.

The Fort Cobb Reservoir Watershed (FCRW) (830 km2) is a watershed within the HELP Washita Basin, located in Caddo and Washita Counties, OK. It is also a benchmark watershed under USDA's Conservation Effects Assessment Project, a national project to quantify environmental effects of USDA and other conservation programs. Population in south-western Oklahoma, in which FCRW is located, is sparse and decreasing. Agricultural focuses on commodity production (beef, wheat, and row crops) with high costs and low margins. Surface and groundwater resources supply public, domestic, and irrigation water. Fort Cobb Reservoir and contributing stream segments are listed on the Oklahoma 303(d) list as not meeting water quality standards based on sedimentation, trophic level of the lake associated with phosphorus loads, and nitrogen in some stream segments in some seasons. Preliminary results from a rapid geomorphic assessment results indicated that unstable stream channels dominate the stream networks and make a significant but unknown contribution to suspended-sediment loadings. Impairment of the lake for municipal water supply, recreation, and fish and wildlife are important factors in local economies. The Thika River Watershed (TRW) (867 km2) is located in central Kenya. Population in TRW is high and increasing, which has led to a poor land-population ratio with population densities ranging from 250 people/km2 to over 500 people/km2. The poor land-population ratio has resulted in land sub-division, fragmentation, over- cultivation, overgrazing, and deforestation which have serious implications on soil erosion, which poses a threat to both agricultural production and downstream reservoirs. Agricultural focuses mainly on subsistence and some cash crops (dairy cattle, corn, beans, coffee, floriculture and pineapple) farming. Surface and groundwater resources supply domestic, public, and hydroelectric power generation water. Thika River supplies 80% of the water for the city of

This notice announces BPA`S`s decision to fund the Oregon Department of Fish and Wildlife (ODFW), the Washington Department of Fish and Wildlife (WDFW), and the Clatsop Economic Development Committee for the Lower Columbia River Terminal Fisheries Research Project (Project). The Project will continue the testing of various species/stocks, rearing regimes, and harvest options for terminal fisheries, as a means to increase lower river sport and commercial harvest of hatchery fish, while providing both greater protection of weaker wild stocks and increasing the return of upriver salmon runs to potential Zone 6 Treaty fisheries. The Project involves relocating hatchery smolts to new, additional pen locations in three bays/sloughs in the lower Columbia River along both the Oregon and Washington sides. The sites are Blind Slough and Tongue Point in Clatsop County, Oregon, and Grays Bay/Deep River, Wahkiakum County, Washington. The smolts will be acclimated for various lengths of time in the net pens and released from these sites. The Project will expand upon an existing terminal fisheries project in Youngs Bay, Oregon. The Project may be expanded to other sites in the future, depending on the results of this initial expansion. BPA`S has determined the project is not a major Federal action significantly affecting the quality of the human environment, within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an environmental impact statement is not required, and BPA`S is issuing this FONSI.

The state of development and the technical potential of hydroelectric power worldwide, in Europe and in Switzerland are briefly compared with each other. Afterwards, the most important types of hydroelectric power stations and their function in the electricity-distribution network, are put forward. The realistic possibilities of development in Switzerland, up to the year 2025, of each type of hydroelectric power station is judged with regard to the currently valid regulations. The effects of the peoples' initiative - 'towards the salvation of our waters' or for stricter regulations for the protection of water - on the chances of realisation of these possibilities of development are shown. The forseeable decrease in the production of energy by the existing hydroelectric power stations, as a result of the regulation planned for rest water, is judged. Various forecasts for the future quantity of hydroelectric power production in Switzerland are put forward. 6 figs., 7 tabs., 12 refs

H. siamensis movement has been severely suppressed in a tributary system where a series of irrigation dams has blocked their migration. H. lobatus collected both below and above the Khone Falls in the mainstream Mekong exhibited statistically different otolith surface elemental signatures but similar core elemental signatures. This result suggests a population originating from a single natal origin but bypassing the waterfalls through a passable side channel where a major hydroelectric dam is planned. The potential effects of damming in the Mekong River are discussed.

Henry, P.
1991-01-01
Hydro-electric energy offers considerable possibilities and advantages which should be exploited before considering the construction of power which use fossil fuels. In fact: - hydro-electric is the only renewable energy available in very large quantities at competitive prices, - there are still many possibilities for producing it since at present only 14% is exploited, - hydraulic machines have been considerably improved over recent years, - the improvements make it possible to use watercourses in successive stages thus considerably reducing damage to the environment, - hydro-electric installations have a regulating effect, - vast areas of uncultivated land can be irrigated using the water reserves created by the artificial lakes. All these reasons favour intensive exploitation of hydro-electric energy reserves, in spite of the initial investment costs, which are sometimes higher than those for constructing fuel/driven power stations.

Fish passage mitigation of impacts from hydroelectric power projects in the United States
International Nuclear Information System (INIS)
Cada, G.F.
1996-01-01
Obstruction of fish movements by dams continues to be the major environmental issue facing the hydropower industry in the US. Dams block upstream migrations, which can cut off adult fish form their historical spawning grounds and severely curtail reproduction. Conversely, downstream-migrating fish may be entrained into the turbine intake flow and suffer turbine-passage injury or mortality. Hydroelectric projects can interfere with the migrations of a wide variety of fish. Maintenance, restoration or enhancement of populations of these species may require the construction of facilities to allow for upstream and downstream fish passage. The Federal Energy Regulatory Commission (FERC), by law, must give fish and wildlife resources equal consideration with power production in its licensing decisions, must be satisfied that a project is consistent with comprehensive plans for a waterway (including fisheries management plans), and must consider all federal and state resource agency terms and conditions for the protection of fish and wildlife. As a consequence, FERC often requires fish passage mitigation measures as a condition of the hydropower license when such measures are deemed necessary for the protection of fish. Much of the recent research and development efforts of the US Department of Energy's Hydropower Program have focused on the mitigation of impacts to upstream and downstream fish passage. This paper descries three components of that effort: (1) a survey of environmental mitigation measures at hydropower sites across the country; (2) a critical review of the effectiveness of fish passage mitigation measures at 16 case study sites; and (3) ongoing efforts to develop new turbine designs that minimize turbine-passage mortality

The Columbia River Distinct Population Segment of bull trout (Salvelinus confluentus) was listed as threatened under the Endangered Species Act in 1998. One of the identified major threats to the species is fragmentation resulting from dams on over-wintering habitats of migratory subpopulations. A migratory subgroup in the Tucannon River appeared to utilize the Snake River reservoirs for adult rearing on a seasonal basis. As a result, a radio telemetry study was conducted on this subgroup from 2002-2006, to help meet Reasonable and Prudent Measures, and Conservation Recommendations associated with the lower Snake River dams in the FCRPS Biological Opinion, and to increase understanding of bull trout movements within the Tucannon River drainage. We sampled 1,109 bull trout in the Tucannon River; 124 of these were surgically implanted with radio tags and PIT tagged, and 681 were only PIT tagged. The remaining 304 fish were either recaptures, or released unmarked. Bull trout seasonal movements within the Tucannon River were similar to those described for other migratory bull trout populations. Bull trout migrated upstream in spring and early summer to the spawning areas in upper portions of the Tucannon River watershed. They quickly moved off the spawning areas in the fall, and either held or continued a slower migration downstream through the winter until early the following spring. During late fall and winter, bull trout were distributed in the lower half of the Tucannon River basin, down to and including the mainstem Snake River below Little Goose Dam. We were unable to adequately radio track bull trout in the Snake River and evaluate their movements or interactions with the federal hydroelectric dams for the following reasons: (1) none of our radio-tagged fish were detected attempting to pass a Snake River dam, (2) our radio tags had poor transmission capability at depths greater than 12.2 m, and (3) the sample size of fish that actually entered the Snake River

Large dams have long been controversial. They offer benefits, such as reduced greenhouse gas emissions, energy security, and local development, yet produce negative social and ecological impact, such as wildlife habitat destruction, human displacement, and the disruption of downstream fishing or agricultural industries. In the past decade, the Indian government has signed Memoranda of Understanding with hydroelectric power companies for the building of over 130 large dams on the Brahmaputra River in the state of Arunachal Pradesh in Northeast India. These dams can generate 43% of India's assessed hydropower potential to sustain India's growing economy. In addition, the Indian government claims that these dams will bring local development with needed jobs. However, local Arunachali people have protested and temporarily halted hydropower projects because of the impact of dams on their existing livelihoods. Using the North Eastern Electric Power Corporation's (NEEPCO) Ranganadi Hydroelectric Project as a case study, our project examined whether dams in Northeast India provide jobs for local people, and whether distance from the dam or work colony to a worker's hometown affects the type of job the worker received. Survey data from residents at NEEPCO's work colony in Doimukh, Arunachal Pradesh, was analyzed using SPSS (n = 18). Our research found that 100% of workers at the dam originally resided in Northeast India, with 33% from Arunachal Pradesh, and 67% from the nearby states of Assam, and Tripura. Further, our analysis revealed no statistically significant relationship between the distance to a worker's hometown and job type (p = .609). Where workers come from did not affect the type of job they received. More research using a larger sample size and additional hydroelectric project case studies is needed to further explore the relationship between worker home location and their job types.

Yakima Fisheries Project revised Draft Environmental Impact Statement: Summary
International Nuclear Information System (INIS)
1995-05-01
The Bonneville Power Administration (BPA) proposes to fund the Yakima Fisheries Project (YFP) to undertake fishery research and enhancement activities in the Yakima River Basin. The State of Washington and the Yakima Indian Nation would jointly direct the project. The Yakima River system is a promising location for mitigation and enhancement to compensate for stock losses from development and operation of hydroelectric projects elsewhere in the Columbia Basin. The YFP would help determine the role that supplementation might play in increasing natural production of anadromous salmonids throughout the Columbia Basin. In cooperation with BPA, the project managers propose to construct, operate and maintain anadromous (e.g. salmon) fish production facilities. The goal is to conduct research activities designed to increase knowledge of supplementation techniques. These techniques would be applied to rebuild naturally spawning anadromous fish stocks historically present in the Yakima River Basin and, ultimately, those throughout the Columbia River Basin. Eventually, the YFP might involve the supplementation of all stocks of anadromous fish known to have occurred in the Yakima Basin. However, at this time only two alternatives have been proposed: Alternative 1 would supplement depressed naturally spawning populations of upper Yakima spring chinook salmon; Alternative 2 (preferred) would include all actions under Alternative 1; it would also add a study to determine the feasibility of re-establishing a naturally spawning population and a significant fall fishery for coho salmon in the Yakima Basin. (Coho smolts are currently being imported from another basin under the Columbia River Basin Fish Management Plan; the stock is now virtually eliminated from the Basin.)

Many of the Corps of Engineers older hydroelectric dams will require major rehabilitation over the next ten years. Preventive maintenance, repair work, and major rehabilitation of the Corp's hydro dams in inadequate because the revenue generated by sales of electricity, by law, is returned to the Treasury. Most multimillion dollar rehabilitation projects require specific approval for funding by Congress and securing it is a long and difficult process. It is hoped the funding problem will soon be addressed by the Clinton administration. Already, nearly one-sixth of the 2,154 Mw of hydro is unavailable because with hydro units are either out of service or operating at less than full capacity

Soomro, G.A.; Sufi, A.B.
2005-01-01
WAPDA being an esteemed organization of the country is involved in development of Water and Power Sector Projects. Ghazi Barotha Hydropower Project is another huge hydropower generation project in the country after Tarbela. The barrage to feed power channel of Ghazi Barotha Power Station are built over River Indus 7 Km down of Tarbela Dam. The project has been constructed to utilize the hydraulic head for power generation that is available between the tailrace of Tarbela Dam and the confluence of Haro River. In this reach river Indus drops by 76 m in distance of 63 Km. This is solely a power generation project with an installed capacity of 1450 MW. The purpose of this paper is to assess the negative impacts on the River Indus due to the construction of GBHP as Water of river Indus will be diverted to the power channel and the river Indus flows go to its lowest in low flow season. The reduction in river flow may change the ecology of the river - belas and people dependant on river water. In this context a study was made to keep the negative environmental impacts as low as possible and suggest mitigation measures to reduce negative impacts and provide enhancement measure to compensate the losses to be sustained by the area people and maintain the social life along with the ecology of the area less disturbed. The study demonstrated that the project is technically sound, economically viable and has limited environmental and social impacts on the area overall and specific the belas and people dependant on the Indus Water from Tarbela downstream up to confluence of Kabul River.

Samoura, K.; Waaub, J.P.
2008-01-01
This article described the environmental impacts caused by the exploitation of one or several dams in tropical coastal basins. In particular, it proposed a methodological approach for analyzing the vulnerability of ecosystems to modifications caused by the exploitation of the Garafiri hydroelectric dam in Guinea. With an installed power capacity of 75 MW, this dam has been operational since 1999 and has supplied electricity to coastal and mid Guinea since 2000. Since then, the ecosystem of the Konkoure River has undergone important changes. This study focused primarily on impacts during the dry season. Data was collected at different hydroelectric stations along the Konkoure Basin to estimate changes in water flow in the estuary. The study showed several changes, including noticeable impacts on the soil salt content. In addition, changes in vegetation were attributed to changes in soil content. The study revealed that rice production has increased 65 per cent since 2000, while salt exploitation has been completely discontinued. It was concluded that the hydraulic management of the dam can have a significant impact on the region's ecosystem which can in turn influence ecological and social economic functions. It was concluded that the vulnerability of the ecosystem can be worsened in the context of climate change. 25 refs., 9 figs

Full Text Available The current drought over the Colorado River Basin has raised concerns that the US Department of the Interior, Bureau of Reclamation (Reclamation may impose water shortages over the lower portion of the basin for the first time in history. The guidelines that determine levels of shortage are affected by relatively short-term (3 to 7 month forecasts determined by the Colorado Basin River Forecast Center (CBRFC using the National Weather Service (NWS River Forecasting System (RFS hydrologic model. While these forecasts by the CBRFC are useful, water managers within the basin are interested in long-term projections of streamflow, particularly under changing climate conditions. In this study, a bias-corrected, statistically downscaled dataset of projected climate is used to force the NWS RFS utilized by the CBRFC to derive projections of streamflow over the Green, Gunnison, and San Juan River headwater basins located within the Colorado River Basin. This study evaluates the impact of changing climate to evapotranspiration rates and contributes to a better understanding of how hydrologic processes change under varying climate conditions. The impact to evapotranspiration rates is taken into consideration and incorporated into the development of streamflow projections over Colorado River headwater basins in this study. Additionally, the NWS RFS is modified to account for impacts to evapotranspiration due to changing temperature over the basin. Adjusting evapotranspiration demands resulted in a 6 % to 13 % average decrease in runoff over the Gunnison River Basin when compared to static evapotranspiration rates. Streamflow projections derived using projections of future climate and the NWS RFS provided by the CBRFC resulted in decreased runoff in 2 of the 3 basins considered. Over the Gunnison and San Juan River basins, a 10 % to 15 % average decrease in basin runoff is projected through the year 2099. However, over the Green River basin, a 5 % to 8

Shaw, R. Todd
1993-04-01
The Umatilla Basin Anadromous Fish Habitat Enhancement Project is funded under the Northwest Power Planning Council's Columbia River Basin Fish and Wildlife Program Measure 704 (d) (1) 34.02 and targets the improvement of water quality and restoration of riparian areas, holding, spawning and rearing habitats of steelhead, spring and fall chinook and coho salmon. The project focused on implementing instream and riparian habitat improvements on private lands on the Umatilla Indian Reservation (hereafter referred to as Reservation) from April 1, 1988 to March 31, 1992. These efforts resulted in enhancement of the lower 1/4 mile of Boston Canyon Creek, the lower 4 river miles of Meacham Creek and 3.2 river miles of the Umatilla River (downstream of the Meacham Creek confluence upstream to the Reservation East Boundary). In 1993, the project shifted emphasis to a comprehensive watershed approach consistent with other basin efforts and began to identify upland and riparian watershed-wide causative factors impacting fisheries habitat and natural fisheries production capabilities throughout the Umatilla River Watershed. Maintenance of existing habitat improvement projects was included under this comprehensive approach. Maintenance of existing gravel traps, instream and bank stabilization structures was required within project areas during the reporting period due to spring flooding damage and high bedload movement. Maintenance activities were completed between river mile (RM) 0.0 and RM 0.25 Boston Canyon Creek, between RM 0.0 and RM 4 Meacham Creek and between RM 78.5 and RM 79 Umatilla River. Habitat enhancement areas were seeded with native grass, legume, shrub and wildflower mixes and planted with willow cuttings to assist in floodplain recovery, stream channel stability and filtering of sediments during high flow periods. Water quality monitoring continued for temperature and turbidity throughout the upper Umatilla River Watershed. Survey of cross sections and

Substantial amounts of organic matter (OM) from terrestrial ecosystems are buried as sediments in inland waters. It is still unclear to what extent this OM constitutes a sink of carbon, and how much of it is returned to the atmosphere upon mineralization to carbon dioxide (CO2). The construction of reservoirs affects the carbon cycle by increasing OM sedimentation at the regional scale. In this study we determine the OM mineralization in the sediment of three zones (river, transition, and dam) of a tropical hydroelectric reservoir in Brazil as well as identify the composition of the carbon pool available for mineralization. We measured sediment organic carbon mineralization rates and related them to the composition of the OM, bacterial abundance and pCO2 of the surface water of the reservoir. Terrestrial OM was an important substrate for the mineralization. In the river and transition zones most of the OM was allochthonous (56 and 48%, respectively) while the dam zone had the lowest allochthonous contribution (7%). The highest mineralization rates were found in the transition zone (154.80 ± 33.50 mg C m(-) (2) d(-) (1)) and the lowest in the dam (51.60 ± 26.80 mg C m(-) (2) d(-) (1)). Moreover, mineralization rates were significantly related to bacterial abundance (r (2) = 0.50, p hydroelectric reservoirs.

Fish vs. power: Remaking salmon, science and society on the Fraser River, 1900--1960
Evenden, Matthew Dominic
Overlapping resource demands made the Fraser River a contested site of development politics in twentieth century British Columbia. Since the turn of the century, power interests surveyed the river's flow, sited dams and promoted development schemes. Fisheries interests, on the other hand, sought to maintain the river as salmon spawning habitat. They questioned the necessity of dams, supported fisheries research and rehabilitation and organized anti-development coalitions. Before the mid-1950s a number of dam projects proceeded on Fraser tributaries and major landslides at Hells Gate modeled the dangers of main stem development. Because of the concerted political lobbying of fisheries groups, the skeptical appraisal of fisheries scientists to development proposals and the legal and political authority of the federal Department of Fisheries and the International Pacific Salmon Fisheries Commission, major dam projects were defeated on the Fraser in the late 1950s. Delayed development on the Fraser helped to spur hydroelectric projects on other rivers in the province; the fish-power problem on the Fraser altered the province's spatial economy of power. Once development began on the Columbia and Peace Rivers, the Fraser was protected by implication. The study combines approaches from environmental history, the history of science and political economy to demonstrate the intersections and interactions between nature, knowledge and society. Research was conducted at eleven archives in Canada and the United States in the papers of organizations, corporations, government departments, politicians, scientists and individuals.

For the past decade, most large-scale hydro development projects in northern Quebec have been put on hold due to land disputes with First Nations. Hydroelectric projects have recently been revived following an agreement signed with Aboriginal communities in the province who recognized the need to find new sources of revenue for future generations. Many Cree are working on the project to harness the waters of the Eastmain River located in the middle of their territory. The work involves building an 890 foot long dam, 30 dikes enclosing a 603 square-km reservoir, a spillway, and a power house with 3 generating units with a total capacity of 480 MW of power for start-up in 2007. The project will require the use of 2,400 workers in total. The Cree Construction and Development Company is working on relations between Quebec's 14,000 Crees and the James Bay Energy Corporation, the subsidiary of Hydro-Quebec which is developing the project. Approximately 10 per cent of the $735-million project has been designated for the environmental component. Inspectors ensure that the project complies fully with environmental protection guidelines. Total development costs for Eastmain-1 are in the order of $2 billion of which $735 million will cover work on site and the remainder will cover generating units, transportation and financial charges. Under the treaty known as the Peace of the Braves, signed in February 2002, the Quebec government and Hydro-Quebec will pay the Cree $70 million annually for 50 years for the right to exploit hydro, mining and forest resources within their territory. The project comes at a time when electricity export volumes to the New England states are down due to growth in Quebec's domestic demand. Hydropower is a renewable and non-polluting source of energy that is one of the most acceptable forms of energy where the Kyoto Protocol is concerned. It was emphasized that large-scale hydro-electric projects are needed to provide sufficient energy to meet both

IPCC AR5 (2014) reported that rainfall in the middle latitudes of the Northern Hemisphere has been increasing since 1901, and it is claimed that warmer climate will increase the risk of floods. In contrast, world water demand is forecasted to exceed a sustainable supply by 40 percent by 2030. In order to avoid this expectable water shortage, securing new water resources has become an utmost challenge. However, flood risk prevention and the secure of water resources are contradictory. To solve this problem, we can use existing hydroelectric dams not only as energy resources but also for flood control. However, in case of Japan, hydroelectric dams take no responsibility for it, and benefits have not been discussed accrued by controlling flood by hydroelectric dams, namely by using preliminary water release from them. Therefore, our paper proposes methodology for assessing those benefits. This methodology has three stages as shown in Fig. 1. First, RRI model is used to model flood events, taking account of the probability of rainfall. Second, flood damage is calculated using assets in inundation areas multiplied by the inundation depths generated by that RRI model. Third, the losses stemming from preliminary water release are calculated, and adding them to flood damage, overall losses are calculated. We can evaluate the benefits by changing the volume of preliminary release. As a result, shown in Fig. 2, the use of hydroelectric dams to control flooding creates 20 billion Yen benefits, in the probability of three-day-ahead rainfall prediction of the assumed maximum rainfall in Oi River, in the Shizuoka Pref. of Japan. As the third priority in the Sendai Framework for Disaster Risk Reduction 2015-2030, `investing in disaster risk reduction for resilience - public and private investment in disaster risk prevention and reduction through structural and non-structural measures' was adopted. The accuracy of rainfall prediction is the key factor in maximizing the benefits

Construction of a small hydroelectric power station provides additional amounts of electric energy, engages a private capital, revives investment activities and promotes the use of renewable energy sources. Transmission losses are reduced, a voltage of higher quality is achieved and idle power is compensated by the generation of electricity in the small hydroelectric power stations and at the place of consumption. Legislation and technical regulations, however, require a multidisciplinary approach, defining of complex spaces and environmental protection. Unfortunately, complete documents should be prepared for small,hydroelectric plants just as for big ones what is a long procedure and many of those papers are unnecessary or even superfluous.

The flood pulse of large Amazonian Rivers is characterized by predictable high- and low-water periods during the annual cycle, and is the main driving force in the floodplains regulating decomposition, nutrient cycles, productivity, life cycles and growth rhythms of floodplains' biota. Over at least 20 millions of years, tree species in these ecosystems developed complex adaptative mechanisms to tolerate flooding, such as the tree species Macrolobium acaciifolium (Fabaceae) and Eschweilera tenuifolia (Lecythidaceae) occupying the lower topographic positions in the floodplain forests along the oligothrophic black-water rivers. Tree growth occurs mainly during terrestrial phase, while during the aquatic phase the anoxic conditions result into a cambial dormancy and formation of annual tree rings. The hydroelectric dam Balbina which was installed in the Uatumã River (central Amazonia) during the 1980s altered significantly the flood pulse regime resulting into higher minimum and lower maximum annual water levels. The suppression of the terrestrial phase caused large-scale mortality of flood-adapted trees growing on the lower topographic positions, as evidenced by radiocarbon dating and cross-dating techniques (dendrochronology). In this study we estimated the extension of dead forests using high resolution ALOS/PALSAR radar images, for their detection along a fluvial distance of more than 280 km downstream of the power plant. Further we analyzed tree growth of 60 living individuals of E. tenuifolia by tree-ring analyses comparing the post- and pre-dam periods. We evaluated the impacts of the altered hydrological regime on tree growth considering ontogenetic effects and the fluvial distance of the trees to the dam. Since the Balbina power plant started operating the associated igapó forests lost about 11% of its cover. We found a significant reduction of tree growth of E. tenuifolia during the post-dam period as a consequence of the increasing aquatic phase duration

Two dams are operated on the Senegal river to prevent salt water from going upstream, to regularize the river flow and to make possible permanent navigation on the river, and to undertake irrigation and hydroelectric energy production projects. A few years after the filling of the last dam, the environmental and health consequences proved not to be as beneficial as expected. Problems emerged in four areas: (1) irrigated agriculture was not as popular as forecast, (2) tenure problems became widespread, (3) health problems related to various kinds of bilharziosis were noticed, and (4) environmental problems related to the lower salinity of the water, and water pollution due to the use of fertilizers occurred. Ecological changes along the river were also significant. Water management proposals and other corrective measures that should be taken to preserve the river as a source of life-sustaining water, and to avoid social and economic disaster for the riparian countries of Mauritania, Mali and Senegal, were described. 14 refs., 1 fig

Turbulence at Hydroelectric Power Plants and its Potential Effects on Fish.
Energy Technology Data Exchange (ETDEWEB)
Cada, Glenn F.; Odeh, Mufeed
2001-01-01
The fundamental influence of fluid dynamics on aquatic organisms is receiving increasing attention among aquatic ecologists. For example, the importance of turbulence to ocean plankton has long been a subject of investigation (Peters and Redondo 1997). More recently, studies have begun to emerge that explicitly consider the effects of shear and turbulence on freshwater invertebrates (Statzner et al. 1988; Hart et al. 1996) and fishes (Pavlov et al. 1994, 1995). Hydraulic shear stress and turbulence are interdependent natural fluid phenomena that are important to fish, and consequently it is important to develop an understanding of how fish sense, react to, and perhaps utilize these phenomena under normal river flows. The appropriate reaction to turbulence may promote movement of migratory fish or prevent displacement of resident fish. It has been suggested that one of the adverse effects of flow regulation by hydroelectric projects is the reduction of normal turbulence, particularly in the headwaters of reservoirs, which can lead to disorientation and slowing of migration (Williams et al. 1996; Coutant et al. 1997; Coutant 1998). On the other hand, greatly elevated levels of shear and turbulence may be injurious to fish; injuries can range from removal of the mucous layer on the body surface to descaling to torn opercula, popped eyes, and decapitation (Neitzel et al. 2000a,b). Damaging levels of fluid stress can occur in a variety of circumstances in both natural and man-made environments. This paper discusses the effects of shear stress and turbulence on fish, with an emphasis on potentially damaging levels in man-made environments. It defines these phenomena, describes studies that have been conducted to understand their effects, and identifies gaps in our knowledge. In particular, this report reviews the available information on the levels of turbulence that can occur within hydroelectric power plants, and the associated biological effects. The final section

Power market liberalisation: an opportunity for the hydroelectricity?
International Nuclear Information System (INIS)
Loth, P.
2001-01-01
This article discusses the future of hydroelectricity in the light of the ongoing liberalisation of the European power market. Compared to fossil electricity, hydroelectricity is a renewable energy source, has a limited impact on the environment, is able to meet strong variations of power demand, but is a little bit more costly. Hydroelectric companies expect the introduction of a quality label for their product as well as the increasing awareness of consumers for environmental aspects to become strong incentives for them to subscribe on green energy despite its higher cost. The cost difference will also be partly reduced by the introduction of a pollution tax on fossil energy sources. Figures on hydroelectricity capacity production, currently and in the near future, in the countries surrounding the Alps are presented. As an example, the business strategy of a Swiss electricity utility is shortly described

The hydrogen economy urgently needs environmentally sustainable hydroelectricity
International Nuclear Information System (INIS)
Goodland, R.
1995-01-01
Only two sources of energy were said to have the capacity to bridge the transition to fully sustainable and renewable energy, namely natural gas and hydro. The argument was made that because of this advantage, both forms will have to be promoted fast, since the transition to sustainable energy is urgent. In so far as natural gas supplies are concerned, it was estimated that they will last for perhaps the next 50 years, whereas hydroelectric potential is practically unlimited. Developing nations could vastly accelerate their development, reduce poverty and approach sustainability by exporting hydro to industrial countries. Similarly, industrial nations switching from fossil fuels to hydrogen could move up the environmental ranking, and significantly help alleviating global pollution and climate risks. Environmental ranking of new energy sources, world reservoirs of hydroelectric power, environmental and social ranking of hydro sites, the environmental impacts of hydro projects, and the concept of environmental sustainability in hydro reservoirs, were summarized. Greater acceptance of the need for sustainable development by the hydro industry was urged, along with more care in selecting hydro development sites with sustainability as a prime objective. 23 refs., 6 figs

The Hood River subbasin is home to four species of anadromous salmonids: chinook salmon (Oncorhynchus tshawytscha), coho salmon (Oncorhynchus kisutch), steelhead (Oncorhynchus mykiss), and sea run cutthroat trout (Salmo clarki). Indigenous spring chinook salmon were extirpated during the late 1960's. The naturally spawning spring chinook salmon currently present in the subbasin are progeny of Deschutes stock. Historically, the Hood River subbasin hatchery steelhead program utilized out-of-basin stocks for many years. Indigenous stocks of summer and winter steelhead were listed in March 1998 by National Marine Fisheries Service (NMFS) under the Endangered Species Act (ESA) as a ''Threatened'' Species along with similar genetically similar steelhead in the Lower Columbia Basin. This annual report summarizes work for two consecutive contract periods: the fiscal year (FY) 1999 contract period was 1 October, 1998 through 30 September, 1999 and 1 October, 1999 through 30 September, 2000 for FY 2000. Work implemented during FY 1999 and FY 2000 included (1) acclimation of hatchery spring chinook salmon and hatchery summer and winter steelhead smolts, (2) spring chinook salmon spawning ground surveys on the West Fork Hood River (3) genetic analysis of steelhead and cutthroat[contractual service with the ODFW], (4) Hood River water temperature studies, (5) Oak Springs Hatchery (OSH) and Round Butte Hatchery (RBH) coded-wire tagging and clipping evaluation, (6) preparation of the Hood River Watershed Assessment (Coccoli et al., December 1999) and the Fish Habitat Protection, Restoration, and Monitoring Plan (Coccoli et al., February 2000), (7) project implementation of early action habitat protection and restoration projects, (8) Pelton Ladder evaluation studies, (9) management oversight and guidance to BPA and ODFW engineering on HRPP facilities, and (10) preparation of an annual report summarizing project objectives for FY 1999 and FY 2000

2002-01-01
The goal of the U.S. Department of Energy (DOE) Clean Coal Technology Program (CCT) is to furnish the energy marketplace with a number of advanced, more efficient, and environmentally responsible coal utilization technologies through demonstration projects. These projects seek to establish the commercial feasibility of the most promising advanced coal technologies that have developed beyond the proof-of-concept stage. This document serves as a DOE post-project assessment (PPA) of a project selected in CCT Round IV, the Wabash River Coal Gasification Repowering (WRCGR) Project, as described in a Report to Congress (U.S. Department of Energy 1992). Repowering consists of replacing an existing coal-fired boiler with one or more clean coal technologies to achieve significantly improved environmental performance. The desire to demonstrate utility repowering with a two-stage, pressurized, oxygen-blown, entrained-flow, integrated gasification combined-cycle (IGCC) system prompted Destec Energy, Inc., and PSI Energy, Inc., to form a joint venture and submit a proposal for this project. In July 1992, the Wabash River Coal Gasification Repowering Project Joint Venture (WRCGRPJV, the Participant) entered into a cooperative agreement with DOE to conduct this project. The project was sited at PSI Energy's Wabash River Generating Station, located in West Terre Haute, Indiana. The purpose of this CCT project was to demonstrate IGCC repowering using a Destec gasifier and to assess long-term reliability, availability, and maintainability of the system at a fully commercial scale. DOE provided 50 percent of the total project funding (for capital and operating costs during the demonstration period) of$438 million

This paper discusses the application of marginal cost concepts to the expansion planning of hydroelectric systems. It is shown that the renumeration of hydroelectric plants should not be based on their energy production, as this leads to excessive revenues for the plant owner, and distorts the dimensioning of upstream reservoirs. In order to produce the adequate economic signals, it is necessary to separate the contributions of turbines and reservoirs. Examples from the Brazilian power system are presented and discussed

The life of the World Commission on Dams (WCD) is due to end in mid-2000. In order to achieve its objective of making recommendations on the environmental, social, economic and institutional questions on dams, it will conduct up to ten case studies where the dams and river basins have been selected according to their age, function, regional representation and the lessons to be learned. The Orange River project in South Africa is being used as a pilot study for the other case studies and the reactions to the study are discussed. The case studies will focus on planning, implementation and operation of the dams with respect to their river basins. Six questions are listed and these will need to be answered to form a basis for a structured approach. To date, stakeholder meetings and fieldwork have highlighted four common generic difficulties and these are listed. A form for completion by interested parties was included with the article. (UK)

2008-07-01
Hydroelectricity is a clean and renewable energy source for many countries, and is expected to play an important role in future energy supplies. However, the impact of climatic change on hydroelectricity resources is not yet understood. This study provided a critical review of current methods used to determine the potential impacts of climatic change on hydroelectric power production. General circulation models (GCMs) are used to predict future climate conditions under various greenhouse gas (GHG) emissions scenarios. Statistical techniques are then used to down-scale GCM outputs to the appropriate scales needed for hydrological models, which are then used to simulate the effects of climatic change at regional and local scales. Outputs from the models are then used to develop water management models for hydroelectric power production. Observed linear trends in annual precipitation during the twentieth century were provided. The theoretical advantages and disadvantages of various modelling techniques were reviewed. Risk assessment strategies for Hydro-Quebec were also outlined and results of the study will be used to guide research programs for the hydroelectric power industry. refs., tabs., figs.

Bonneville Power Administration (BPA) proposes to mitigate for loss of wildlife habitat caused by the development of Columbia River Basin hydroelectric projects, including McNary dam. The proposed wildlife mitigation project involves wildlife conservation on 1140 hectares (ha)(2817 acres) of land (including water rights) in Umatilla County, Oregon. BPA has prepared an Environmental Assessment (EA)(DOE/EA- 1016) evaluating the proposed project. Based on the analysis in the EA, BPA has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an Environmental Impact Statement (EIS) is not required, and BPA is issuing this Finding of No Significant Impact (FONSI)

Full Text Available Substantial amounts of organic matter (OM from terrestrial ecosystems are buried as sediments in inland waters. It is still unclear to what extent this OM constitutes a sink of carbon, and how much of it is returned to the atmosphere upon mineralization to carbon dioxide (CO2. The construction of reservoirs affects the carbon cycle by increasing OM sedimentation at the regional scale. In this study we determine the OM mineralization in the sediment of three zones (river, transition and dam of a tropical hydroelectric reservoir in Brazil as well as identify the composition of the carbon pool available for mineralization. We measured sediment OC mineralization rates and related them to the composition of the OM, bacterial abundance and pCO2 of the surface water of the reservoir. Terrestrial OM was an important substrate for the mineralization. In the river and transition zones most of the OM was allochthonous (56 % and 48 %, respectively while the dam zone had the lowest allochthonous contribution (7 %. The highest mineralization rates were found in the transition zone (154.80 ± 33.50 mg C m-2 d-1 and the lowest in the dam (51.60 ± 26.80 mg C m-2 d-1. Moreover, mineralization rates were significantly related to bacterial abundance (r2 = 0.50, p < 0.001 and pCO2 in the surface water of the reservoir (r2 = 0.73, p < 0.001. The results indicate that allochthonous OM has different contributions to sediment mineralization in the three zones of the reservoir. Further, the sediment mineralization, mediated by heterotrophic bacteria metabolism, significantly contributes to CO2 supersaturation in the water column, resulting in higher pCO2 in the river and transition zones in comparison with the dam zone, affecting greenhouse gas emission estimations from hydroelectric reservoirs.

Hydroelectric power contributes about 10 percent of the electrical energy generated in the United States, and nearly 20 percent of the worlds electrical energy. The contribution of hydroelectric generation has declined in recent years, often as a consequence of environmental concerns centering around (1) restriction of upstream and downstream fish passage by the dam, and (2) alteration of water quality and river flows by the impoundment. The Advanced Hydropower Turbine System (AHTS) Program of the U.S. Department of Energy is developing turbine technology which would help to maximize global hydropower resources while minimizing adverse environmental effects. Major technical goals for the Program are (1) the reduction of mortality among turbine-passed fish to 2 percent or less, compared to current levels ranging up to 30 percent or greater; and (2) development of aerating turbines that would ensure that water discharged from reservoirs has a dissolved oxygen concentration of at least 6 mg/L. These advanced, environmentally friendly turbines would be suitable both for new hydropower installations and for retrofitting at existing dams. Several new turbine designs that have been he AHTS program are described

Shaw, R.Todd
1996-05-01
During the 1995 - 96 project period, four new habitat enhancement projects were implemented under the Umatilla River Basin Anadromous Fish Habitat Enhancement Project by the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) in the upper Umatilla River Basin. A total of 38,644 feet of high tensile smooth wire fencing was constructed along 3.6 miles of riparian corridor in the Meacham Creek, Wildhorse Creek, Greasewood Creek, West Fork of Greasewood Creek and Mission Creek watersheds. Additional enhancements on Wildhorse Creek and the lower Greasewood Creek System included: (1) installation of 0.43 miles of smooth wire between river mile (RM) 10.25 and RM 10.5 Wildhorse Creek (fence posts and structures had been previously placed on this property during the 1994 - 95 project period), (2) construction of 46 sediment retention structures in stream channels and maintenance to 18 existing sediment retention structures between RM 9.5 and RM 10.25 Wildhorse Creek, and (3) revegetation of stream corridor areas and adjacent terraces with 500 pounds of native grass seed or close species equivalents and 5,000 native riparian shrub/tree species to assist in floodplain recovery, stream channel stability and filtering of sediments during high flow periods. U.S. Fish and Wildlife Service (USFWS), Bureau of Indian Affairs (BIA) and Environmental Protection Agency (EPA) funds were cost shared with Bonneville Power Administration (BPA) funds, provided under this project, to accomplish habitat enhancements. Water quality monitoring continued and was expanded for temperature and turbidity throughout the upper Umatilla River Watershed. Physical habitat surveys were conducted on the lower 13 river miles of Wildhorse Creek and within the Greasewood Creek Project Area to characterize habitat quality and to quantify various habitat types by area.

Climate Projections and Drought: Verification for the Colorado River Basin
Santos, N. I.; Piechota, T. C.; Miller, W. P.; Ahmad, S.
2017-12-01
The Colorado River Basin has experienced the driest 17 year period (2000-2016) in over 100 years of historical record keeping. While the Colorado River reservoir system began the current drought at near 100% capacity, reservoir storage has fallen to just above 50% during the drought. Even though federal and state water agencies have worked together to mitigate the impact of the drought and have collaboratively sponsored conservation programs and drought contingency plans, the 17-years of observed data beg the question as to whether the most recent climate projections would have been able to project the current drought's severity. The objective of this study is to analyze observations and ensemble projections (e.g. temperature, precipitation, streamflow) from the CMIP3 and CMIP5 archive in the Colorado River Basin and compare metrics related to skill scores, the Palmer Drought Severity Index, and water supply sustainability index. Furthermore, a sub-ensemble of CMIP3/CMIP5 projections, developed using a teleconnection replication verification technique developed by the author, will also be compared to the observed record to assist in further validating the technique as a usable process to increase skill in climatological projections. In the end, this study will assist to better inform water resource managers about the ability of climate ensembles to project hydroclimatic variability and the appearance of decadal drought periods.

South Asia river-flow projections and their implications for water resources
Mathison, C.; Wiltshire, A. J.; Falloon, P.; Challinor, A. J.
2015-12-01
South Asia is a region with a large and rising population, a high dependence on water intense industries, such as agriculture and a highly variable climate. In recent years, fears over the changing Asian summer monsoon (ASM) and rapidly retreating glaciers together with increasing demands for water resources have caused concern over the reliability of water resources and the potential impact on intensely irrigated crops in this region. Despite these concerns, there is a lack of climate simulations with a high enough resolution to capture the complex orography, and water resource analysis is limited by a lack of observations of the water cycle for the region. In this paper we present the first 25 km resolution regional climate projections of river flow for the South Asia region. Two global climate models (GCMs), which represent the ASM reasonably well are downscaled (1960-2100) using a regional climate model (RCM). In the absence of robust observations, ERA-Interim reanalysis is also downscaled providing a constrained estimate of the water balance for the region for comparison against the GCMs (1990-2006). The RCM river flow is routed using a river-routing model to allow analysis of present-day and future river flows through comparison with available river gauge observations. We examine how useful these simulations are for understanding potential changes in water resources for the South Asia region. In general the downscaled GCMs capture the seasonality of the river flows but overestimate the maximum river flows compared to the observations probably due to a positive rainfall bias and a lack of abstraction in the model. The simulations suggest an increasing trend in annual mean river flows for some of the river gauges in this analysis, in some cases almost doubling by the end of the century. The future maximum river-flow rates still occur during the ASM period, with a magnitude in some cases, greater than the present-day natural variability. Increases in river flow

Hydroelectric power is the most mature and widely implemented of the renewable energy technologies. The energy of flowing water has been used to perform work directly since ancient times, and the use of hydropower turbines to generate electricity traces back to the 19th century. Two commonly used turbine types, the Francis and Kaplan turbines, are essentially refinements of the simple reaction turbine of Hero of Alexandria, dating from about 100 B.C. (NAS 1976). Hydroelectric power production provides over 10% of the net electrical generation in the US, more than petroleum or natural gas and far more than the other renewable energy technologies combined. On a regional basis, hydroelectric power represents 14% of the net electrical power generation in the Rocky Mountain states and nearly 63% along the Pacific Coast. Those states that have the largest percentages of their electricity generated by hydropower (e.g., Idaho, Oregon, Montana, and Washington) also tend to have the lowest average cost of electricity per kilowatt-hour

Corrective, preventive and enhancement measures undertaken as part of the development of the Laforge-2 Hydroelectric Power Plant, were described. The environment into which the project has been integrated was also described. General background information and technical characteristics of the Laforge-2 and Caniapiscau-Laforge diversion were provided. The Laforge-2 Mitigative Master Plan's measures for improving wildlife potential, cleaning-up of tributaries, protecting wildlife habitats, seeding around ponds and humid zones, installing platforms to encourage and facilitate the nesting of ospreys, and promoting proper harvesting of the territory, were described as corrective measures that will promote sustainable development. Contractual obligations to protect the environment were outlined. Enhancement measures described included reclamation of areas disturbed during construction, landscaping around main structures and construction of scenic lookouts. It was fully expected that the mitigative measures described for the Laforge-2 project will minimize negative impacts of the project and will maximize positive ones by improving wildlife potential in areas near the reservoir. 5 figs

Recent trends in federal legislation related to the environmental impacts of hydroelectric power projects were reviewed. The study focused on a discussion of recent and proposed amendments to the Species at Risk Act, the Fisheries Act, and the Navigable Waters Protection Act. Challenges associated with risk management, the public perception of risk, and the communication of decisions related to the management and protection of aquatic ecosystems were discussed. The Brilliant Expansion Power Project (BRX) examined the interactions with white sturgeon on the Kootenay River in British Columbia (BC). A monitoring program was conducted during the project's construction in order to reduce the risk to sturgeon from blasting. A habitat enhancement feature was also constructed. It was concluded that the mitigation strategies used during the BRX project provide a useful example of innovation and adaptive management. 19 refs.

2013-12-01
Full Text Available The brown trout (Salmo trutta L. in the Mislinja River has been endangered for years because of small hydroelectric power plants. To find out how they are affecting the population of the brown trout in the Mislinja River, we conducted a sampling of the brown trout, using a generating set. We measured the length and weight of all caught specimens and analysed the obtained data. The results are presented in this paper, e.g., biomass, estimations of abundance, average weight, average length and number of captured brown trout. We discovered that the population of the brown trout has decreased in all the sections where water has been taken away for small hydroelectric power plants.

Reflections on hydroelectric dams in the Amazon: water, energy and development
Directory of Open Access Journals (Sweden)
Bertha Koiffmann Becker
2012-12-01
Full Text Available The essay discusses the deployment of hydroelectric dams in the Amazon having as a starting point the relations between water and hydropower consumption at different scales of analyses. So, if all parts of the world are affected by global processes, they are not in the same way. The global scale is dominated by the apocalyptic discourse of increasing water scarcity and global warming, requiring the reduction of emissions of greenhouse gases through the use of renewable energy and new technologies. On a Brazilian national scale, the problems are, rather, how to manage the abundance of water with social and territorial justice, and how to stop the loss of 20% of the electricity produced. Finally, it is at the regional scale - in the Amazon - that major problems arise: i the biggest paradox between the abundance of water and social inaccessibility to this resource; ii most of the dams planned for the country will be built there, with the risk of negative impacts already known; iii the obligation of building sluices at all the proposed dams, suggested by the industrial sector in name of the rivers navigation, will serve, in fact, to export commodities produced in the Brazilian central region. An ethical question is, therefore, posed to society and to Brazilian government: are really needed so many hydroelectric dams in the Amazon?

We are using a large-scale, high-resolution, fully integrated hydrological/reservoir/hydroelectricity model to investigate the impact of climate change on the operation of 11037 dams and generation of electricity from 375 hydroelectric power plants in the Northeastern United States. Moreover, we estimate the hydropower potential of the region by energizing the existing non-powered dams and then studying the impact of climate change on the hydropower potential. We show that climate change increases the impact of dams on the hydrology of the region. Warmer temperatures produce shorter frozen periods, earlier snowmelt and elevated evapotranspiration rates, which when combined with changes in precipitation, are projected to increase water availability in winter but reduce it during summer. As a result, the water that is stored by dams will be more than ever a necessary part of the routine water systems operations to compensate for these seasonal imbalances. The function of dams as emergency water storage for creating drought resiliency will mostly diminish in the future. Building more dams to cope with the local impacts of climate change on water resources and to offset the increased drought vulnerability may thus be inevitable. Annual hydroelectricity generation in the region is 41 Twh. Our estimate of the annual hydropower potential of non-powered dams adds up to 350 Twh. Climate change may reduce hydropower potential from non-powered dams by up to 13% and reduce current hydroelectricity generation by up to 8% annually. Hydroelectricity generation and hydropower potential may increase in winter months and decline in months of summer and fall. These changes call for recalibration of dam operations and may raise conflict of interests in multipurpose dams.

to protect, enhance, and mitigate fish and wildlife resources impacted by Columbia River Basin hydroelectric development. The effort is one of several wildlife mitigation projects in the region developed to compensate for terrestrial habitat losses resulting from the construction of McNary and John Day Hydroelectric facilities located on the mainstem Columbia River. While this project is driven primarily by the purpose and need to mitigate for wildlife habitat losses, it is also recognized that management strategies will also benefit many other non-target fish and wildlife species and associated natural resources. The Rainwater project is much more than a wildlife project--it is a watershed project with potential to benefit resources at the watershed scale. Goals and objectives presented in the following sections include both mitigation and non-mitigation related goals and objectives.

The main features of 46 hydroelectric dams and diversions in British Columbia are reviewed, and available information on the inland sport fish resources within and below the impoundments are summarized. The projects are collectively responsible for ca 95% of the electrical power used in the province. The characteristics detailed include water license and operational constraints, electrical generation, enhancement facilities, operational regime, physical and chemical environment, downstream system, sportfish populations, and recreational fishery. All the hydroelectric impoundments reviewed, with the possible exceptions of some small headponds, support sport fish populations. Recreational angling quality is considered good for about one quarter of impoundments for which information is available. Low population density is the dominant reason for poor angling quality. Drawdowns exceeding 10 m annually and/or low water retention times are significant impediments to sport fish stock densities. Recommended measures to improve sport fishery resources in and below hydroelectric impoundments include evaluation of the efficiency of ongoing compensation programs, improvement to impact assessment procedures to ensure adequate documentation of pre- and post-impoundment conditions, and enhancement of several systems through stock or nutritional supplementation. 161 refs., 95 figs., 9 tabs

Benefits and applications of modular hydroelectric pumped storage
International Nuclear Information System (INIS)
Koebbe, R.S.
1991-01-01
This paper reports on hydroelectric pumped storage which is the only proven and most efficient technology available for energy storage. It is used by utilities to provide peak and intermediate power and to optimize overall system performance. Because of increased environmental and regulatory constraints, few acceptable sites, long schedules, and huge financial commitments, large conventional pumped storage plants, are now virtually impossible to build. As an alternative, small modular pumped storage, with project sizes ranging from 25 MW to 200 MW, was created to overcome the difficulties of conventional projects. The modular approach involves standardizing the elements of a pumped storage plant by utilizing specialized siting techniques and optimizing design, equipment, and construction. Compared with conventional pumped storage, the modular design can reduce cost and expedite schedule; reduce environmental concerns and permitting obstacles; and expand applications of energy storage on a utility's system

The data review method and field investigation were used to evaluate the effect of the water conservancy schistosomiasis control projects combined with molluscicide to control O. hupensis snails. After the projects of the water level control and concrete slope protection and mollusciciding were implemented, the snails in the project river sections were completely eliminated. The snail diffusion did not happen in the inland irrigation area too. In the outside of the river beach, though the snails still existed, the snail densities plunged below 1.0 snail per 1.0 m 2 . The comprehensive measures of the combination of water level control, concrete slope protection and mollusciciding can effectively control and eliminate the snails, and prevent the snails from spreading.

Widespread Forest Vertebrate Extinctions Induced by a Mega Hydroelectric Dam in Lowland Amazonia.
Directory of Open Access Journals (Sweden)

Full Text Available Mega hydropower projects in tropical forests pose a major emergent threat to terrestrial and freshwater biodiversity worldwide. Despite the unprecedented number of existing, under-construction and planned hydroelectric dams in lowland tropical forests, long-term effects on biodiversity have yet to be evaluated. We examine how medium and large-bodied assemblages of terrestrial and arboreal vertebrates (including 35 mammal, bird and tortoise species responded to the drastic 26-year post-isolation history of archipelagic alteration in landscape structure and habitat quality in a major hydroelectric reservoir of Central Amazonia. The Balbina Hydroelectric Dam inundated 3,129 km2 of primary forests, simultaneously isolating 3,546 land-bridge islands. We conducted intensive biodiversity surveys at 37 of those islands and three adjacent continuous forests using a combination of four survey techniques, and detected strong forest habitat area effects in explaining patterns of vertebrate extinction. Beyond clear area effects, edge-mediated surface fire disturbance was the most important additional driver of species loss, particularly in islands smaller than 10 ha. Based on species-area models, we predict that only 0.7% of all islands now harbor a species-rich vertebrate assemblage consisting of ≥80% of all species. We highlight the colossal erosion in vertebrate diversity driven by a man-made dam and show that the biodiversity impacts of mega dams in lowland tropical forest regions have been severely overlooked. The geopolitical strategy to deploy many more large hydropower infrastructure projects in regions like lowland Amazonia should be urgently reassessed, and we strongly advise that long-term biodiversity impacts should be explicitly included in pre-approval environmental impact assessments.

In the Northeast region, the physical potential for all sites exceeds 33,000 MW of capacity with an estimated average annual energy of some 153,000 GWH. By comparison, the available data represent about 6% of the total capacity and 11% of the hydroelectric energy potential estimated for the entire US. Of the total capacity estimated for the region, 6100 MW has been installed. The remainder (27,200 MW, excluding the undeveloped capacity in the New England States) is the maximum which could be developed by upgrading and expanding existing projects (18,700 MW), and by installing new hydroelectric power capacity at all potentially feasible, undeveloped sites (8500 MW). Small-scale facilities account for about 15% of the region's total installed capacity, but another 1800 MW could be added to these and other small water-resource projects. In addition, 500 MW could be installed at potentially feasible, undeveloped small-scale sites. The small-scale resource varies considerably, with the states of New York, Maine, and New Hampshire having the largest potential for incremental development at existing projects in the Northeast region. West Virginia, Maryland, Delaware, New Jersey, Pennsylvania, New York, Connecticut, Massachusetts, Rhode Island, New Hampshire, Vermont, and Maine comprise the Northeast region.

Since the 1970’s, an increasing amount of specialized research has focused on the problems created by instability of internal flow in hydroelectric power plants. However, progress in this field is hampered by the interdisciplinary nature of the subject, between fluid mechanics, structural mechanics and hydraulic transients. Flow-induced Pulsation and Vibration in Hydroelectric Machinery provides a compact guidebook explaining the many different underlying physical mechanisms and their possible effects. Typical phenomena are described to assist in the proper diagnosis of problems and various key strategies for solution are compared and considered with support from practical experience and real-life examples. The link between state-of the-art CFD computation and notorious practical problems is discussed and quantitative data is provided on normal levels of vibration and pulsation so realistic limits can be set for future projects. Current projects are also addressed as the possibilities and limitatio...

Small-scale hydroelectric power in the Pacific Northwest: new impetus for an old energy source
Energy Technology Data Exchange (ETDEWEB)
1980-07-01
Energy supply is one of the most important issues facing Northwestern legislators today. To meet the challenge, state legislatures must address the development of alternative energy sources. The Small-Scale Hydroelectric Power Policy Project of the National Conference of State Legislators (NCSL) was designed to assist state legislators in looking at the benefits of one alternative, small-scale hydro. Because of the need for state legislative support in the development of small-scale hydroelectric, NCSL, as part of its contract with the Department of Energy, conducted the following conference on small-scale hydro in the Pacific Northwest. The conference was designed to identify state obstacles to development and to explore options for change available to policymakers. A summary of the conference proceedings is presented.

If small hydroelectric power plants are defined to be hydroelectric power plants of up to a few 1000 kW, they should be shelf goods because of cost considerations. Design of small hydroelectric power plants is a many-sided optimization task, on a level with constructing larger hydro power plants. But the budget for a small hydro power plant does not permit any comprehensive evaluations. The most important costs are the one-time costs in the form of investments and the following annual costs in the form of operation and maintenance, and losses. Financing costs are not considered in this article

Wabash River Coal Gasification Repowering Project: A DOE Assessment; FINAL
International Nuclear Information System (INIS)
National Energy Technology Laboratory
2002-01-01
The goal of the U.S. Department of Energy (DOE) Clean Coal Technology Program (CCT) is to furnish the energy marketplace with a number of advanced, more efficient, and environmentally responsible coal utilization technologies through demonstration projects. These projects seek to establish the commercial feasibility of the most promising advanced coal technologies that have developed beyond the proof-of-concept stage. This document serves as a DOE post-project assessment (PPA) of a project selected in CCT Round IV, the Wabash River Coal Gasification Repowering (WRCGR) Project, as described in a Report to Congress (U.S. Department of Energy 1992). Repowering consists of replacing an existing coal-fired boiler with one or more clean coal technologies to achieve significantly improved environmental performance. The desire to demonstrate utility repowering with a two-stage, pressurized, oxygen-blown, entrained-flow, integrated gasification combined-cycle (IGCC) system prompted Destec Energy, Inc., and PSI Energy, Inc., to form a joint venture and submit a proposal for this project. In July 1992, the Wabash River Coal Gasification Repowering Project Joint Venture (WRCGRPJV, the Participant) entered into a cooperative agreement with DOE to conduct this project. The project was sited at PSI Energy's Wabash River Generating Station, located in West Terre Haute, Indiana. The purpose of this CCT project was to demonstrate IGCC repowering using a Destec gasifier and to assess long-term reliability, availability, and maintainability of the system at a fully commercial scale. DOE provided 50 percent of the total project funding (for capital and operating costs during the demonstration period) of$438 million. Construction for the demonstration project was started in July 1993. Pre-operational tests were initiated in August 1995, and construction was completed in November 1995. Commercial operation began in November 1995, and the demonstration period was completed in December

The Hood River Production Program Monitoring and Evaluation Project is co-managed by the Confederated Tribes of Warm Springs (CTWSRO) and the Oregon Department of Fish and Wildlife. The program is divided up to share responsibilities, provide efficiency, and avoid duplication. From October 2002 to September 2003 (FY 03) project strategies were implemented to monitor, protect, and restore anadromous fish and fish habitat in the Hood River subbasin. A description of the progress during FY 03 is reported here. Additionally an independent review of the entire program was completed in 2003. The purpose of the review was to determine if project goals and actions were achieved, look at critical uncertainties for present and future actions, determine cost effectiveness, and choose remedies that would increase program success. There were some immediate changes to the implementation of the project, but the bulk of the recommendations will be realized in coming years.

The Baspa River is one of the most important tributaries to the Sutlej River in the NW Himalaya (India). Its catchment is 1116 km2 in size, ranges from c. 6400 m asl to 1770 m asl and contains India's largest private hydroelectric facility, the 300 MW Baspa II. Geologically, the hydroelectric installation is located in the Higher Himalayan Crystalline, just above the active Karcham Normal Fault, which is reactivating the Early Miocene Main Central Thrust, one of the principal Himalayan faults. The area is seismically active and mass-movements are common. Around 8200 yrs BP the Baspa was dammed by a rock-avalanche dam, leading to the formation of the originally c. 260 m deep palaeo-lake Sangla palaeo-lake. Detailed sedimentological investigations and radiocarbon dating indicate that the palaeo-lake was completely filled with sediments until c. 5100 yrs BP. This makes the Sangla palaeo-lake to a very rare example of a mass-movement dam with very long duration and its lacustrine sediments represent a valuable archive for geological processes and environmental proxies within the Baspa catchment during the c. 3100 years of its existence - which are the aim of our study. At least 5 levels of soft-sediment deformation have been recorded in the exposed part of the lacustrine sediments of Sangla palaeo-lake, including brecciated laminae, overturned laminae, folds, faults and deformation bands, separated by undeformed deposits. They are interpreted as seismites, indicating at least 5 earthquakes within 2500 years strong enough to cause liquefaction. The 300 MW Baspa II hydro-electric power plant has been built exactly on top of this palaeo-lake. This special location represents a very rare possibility to evaluate the short-term, river load and hydrological parameters measured during the planning and operational stages of Baspa II with the long-term parameters gained from the palaeo-lake sediments from the catchment. This data show that the Mid-Holocene erosion rates of the

THE DYNAMIC OF USING THE RIVERS ENERGY FROM REPUBLIC OF MOLDOVA TERRITORY
Directory of Open Access Journals (Sweden)
DIANA BRAGA

Full Text Available The dynamic of using the rivers energy from Republic of Moldova territory. One of the least explored and tapped energy sources in Moldova are the inland rivers. Considering the critical condition of the country regarding energy sources, it would be highly necessary to study the feasibility of hydraulic energy reserves. Although Moldova has no major rivers with a large flow of water, the network of small tributaries of its two large rivers, Dniester and Prut, could be used to a certain extent for partial power supply to villages situated along inland watercourses.The first scientific developments concerning the hydropower potential of the rivers in Bessarabia belong to professor D. Pavel. Around 1933 he was suggesting a series of hydro-technical facilities on Prut and Dniester rivers and their tributaries. Subsequently, in the ‘40s of the 20th century the first power plants were built on small rivers. After World War II some small hydropower plants, built during the interwar period, had been restored and some other put into operation. These include the plant at Dubăsari with a capacity of 48 MW that started operating in 1954 on Dniester River, and the hydroelectric complex at Costeşti -Stânca with a capacity of 16 MW, in 1978 on the River Prut. Nevertheless, the leverage of hydroelectric resources is not significant, only 23 being used nowadays, which is 7% of the hydropower potential - a rather modest number compared to other states.

Project NOAH: Regulating modern sea-level rise. Phase II: Jerusalem Underground
Newman, Walter S.; Fairbridge, Rhodes W.
This proposal builds a high-speed inter-urban express between Jerusalem and Tel Aviv, generates 1500 megawatts of hydroelectric energy, curtails littoral erosion, builds a port along the Israeli Mediterranean coast and demands peaceful cooperation on both sides of the Jordan River. Phase II represents a pilot project demonstrating the feasibility of continuing to regulate world sea-level by a new series of water regulation schemes. Phase I previously described all those projects already completed or underway which have inadvertently and/or unintentionally served the purpose of sea-level regulation. These forms of Phase I sea-level regulation include large and small reservoirs, irrigation projects, water infiltration schemes, farm ponds, and swimming and reflecting pools. All these water storage projects have already exercised a very appreciable brake on 20th century sea-level rise. Phase II outlines a high-visibility proposal which will serve to illustrate the viability of “Project NOAH”.

The Umatilla Anadromous Fisheries Habitat Project (UAFHP) is an ongoing effort to protect, enhance, and restore riparian and instream habitat for the natural production of anadromous salmonids in the Umatilla River Basin, Northeast Oregon. Flow quantity, water temperature, passage, and lack of in-stream channel complexity have been identified as the key limiting factors in the basin. During the 2008 Fiscal Year (FY) reporting period (February 1, 2008-January 31, 2009) primary project activities focused on improving instream and riparian habitat complexity, migrational passage, and restoring natural channel morphology and floodplain function. Eight primary fisheries habitat enhancement projects were implemented on Meacham Creek, Birch Creek, West Birch Creek, McKay Creek, West Fork Spring Hollow, and the Umatilla River. Specific restoration actions included: (1) rectifying one fish passage barrier on West Birch Creek; (2) participating in six projects planting 10,000 trees and seeding 3225 pounds of native grasses; (3) donating 1000 ft of fencing and 1208 fence posts and associated hardware for 3.6 miles of livestock exclusion fencing projects in riparian areas of West Birch and Meacham Creek, and for tree screens to protect against beaver damage on West Fork Spring Hollow Creek; (4) using biological control (insects) to reduce noxious weeds on three treatment areas covering five acres on Meacham Creek; (5) planning activities for a levee setback project on Meacham Creek. We participated in additional secondary projects as opportunities arose. Baseline and ongoing monitoring and evaluation activities were also completed on major project areas such as conducting photo point monitoring strategies activities at the Meacham Creek Large Wood Implementation Project site (FY2006) and at additional easements and planned project sites. Fish surveys and aquatic habitat inventories were conducted at project sites prior to implementation. Proper selection and implementation of

Small hydroelectric power development in India: a profile

Bhattacharya, Partha

Small hydroelectric power plants (SHPs) have a definite role to play in the contemporary energy scenario generally as a source for supplementing the electrical energy production and particularly in remote rural areas in meeting the energy requirements of isolated communities. SHPs practically do not produce any adverse impact.However, their success depends on the ingenuity of the planners and the designers, and more importantly the convection. Another dimension to the success is the participation and involvement of the beneficiaries of the project which are more relevant for the microhydro electric schemes in the remote areas. The major factor that influences the commercial success of the SHP is marketing. It should be given due emphasis. This necessitates the SHP development activities to be more pragmatic and relevant to the society needs; an approach which is programme-based, rather than a project-oriented, is needed.

The Pasvik River is one of the largest rivers in the Northern Fennoscandia and constitutes the border between Norway and Russia, with catchment area in Finland, Norway and Russia. Besides being strongly regulated for hydroelectric power production, the river is polluted by the smelter in Nikel and other industrial activities and by domestic sewage from the settlements on both sides of the border. This document discusses the pollution of the river and the ecological responses. The two main areas of concern are heavy metals and eutrophication. Very high content of heavy metals in water, lake sediments, macrophytes and fish was found in Kuetsyarvi. Extensive toxic effects were documented on the fish population in the lake. The toxic effects are less than expected from the concentration of heavy metals, which is due to high calcium content, organic matter and eutrophication. Eutrophication is due to the domestic sewage from settlements within the water catchment. Kuetsyarvi has eutrophic status, the lower parts of the Pasvik River have oligo-mesotrophic status according to phosphorus concentrations, and the composition of the planktonic and benthic communities. Because of increased and stabilized water level from hydroelectric power regulations, increased abundance of macrophytes and zoobenthos in shallow areas also have occurred. 77 refs., 32 figs., 28 tabs.

Methane emissions from the hydroelectric dam of Petit-Saut, in French Guyana, were measured over a 20-months period. Since the beginning of the reservoir filling (January 1994), 300 km 2 of tropical forest have been submerged. Biological CH 4 oxidation, in the surface water of the lake and in the river downstream of the dam, lead to an intense 0 2 consumption. Emissions of CH 4 by diffusion into the atmosphere or by degassing of the water released into the river as well as the stock of dissolved gas in the lake, and their temporal dynamics, were studied. Maximum emissions of 700 t (CH 4 ) per day were attained in February 1994, corresponding to maximum dissolved CH 4 concentrations of 14 mg l -1 in the water column. Total emissions since January 1994, were calculated from the whole data set. (authors). 7 refs., 2 figs., 1 tab

Hydroelectricity: an asset for a successful energy transition in France
International Nuclear Information System (INIS)
Galland, J.C.; Vincent, E.
2013-01-01
France's national debate on energy transition has served as a reminder that hydroelectric power plays a significant role in French electricity production. With installed power totalling 25400 MW at end 2012 (the second largest in Europe), France's hydroelectric plants produced 63.8 TWh last year (the third largest in Europe), almost 12% of total output. It is France's second largest means of producing electricity and it represents more than 80% of production of renewable energy. A source of energy developed a long time ago, thus benefiting from technological maturity, hydroelectricity can be produced in large quantity at the heart of France's regions, while also rendering indispensable service for the equilibrium of the French electricity system by compensating the intermittency of other renewable energy sources. The production costs of hydroelectric power are the lowest among all power generation technologies. (authors)

The use of water wasted in hydroelectric plants as normalization dam excess, which constitute a hydrodynamic potential useful to generate electric energy which can be subsequently used to produce hydrogen and its subsequent consumption in fuel cells has been considered as an alternative for hydraulic energy-rich countries like Brazil. The case is examined in which all the water wasted in the hydroelectric plants, spilled by dam gates to maintain acceptable water levels, from the 3 largest Brazilian hydroelectric plants was used to produce hydrogen. During the year of 2008, the electric energy produced from this utilization would have been equivalent to 52.8 TWh, an amount that corresponds to an increase of ca. 15% of the total electric energy produced in the country. Furthermore, if this amount of hydrogen was used in the replacement of internal combustion vehicles by fuel cells, this would have prevented the production of 2.26 x 10{sup 7} ton of Co{sub 2} per year. This plan would also significantly decrease production and release of greenhouse gases. (author)

The estimates of existing, incremental, and the undeveloped hydropower potential for all states in the various regions of the country are presented. In the Pacific Southwest region, the maximum physical potential for all sites exceeds 33,000 MW of capacity with an estimated average annual energy greater than 85,000 GWH. By comparison, these values represent about 6% of the total potential capacity and hydroelectric energy generation estimated for the entire US. Of the total capacity estimated for the region, 9900 MW has been installed. The remainder (23,200 MW) is the maximum which could be developed by upgrading and expanding existing projects (6000 MW) and by installing new hydroelectric power capacity at all potentially feasible, undeveloped sites (17,200 MW). Small-scale facilities account for less than 4% of the region's total installed capacity, but another 600 MW could be added to these and other small water resource projects. In addition, 600 MW could be installed at potentially feasible, undeveloped small-scale sites. The small-scale resource varies considerably, with the states of California and Utah having the largest potential for incremental development at existing projects in the Pacific Southwest region. States comprising the Southwest are Arizona, California, Hawaii, Nevada, and Utah.

Full Text Available The Atmospheric River Tracking Method Intercomparison Project (ARTMIP is an international collaborative effort to understand and quantify the uncertainties in atmospheric river (AR science based on detection algorithm alone. Currently, there are many AR identification and tracking algorithms in the literature with a wide range of techniques and conclusions. ARTMIP strives to provide the community with information on different methodologies and provide guidance on the most appropriate algorithm for a given science question or region of interest. All ARTMIP participants will implement their detection algorithms on a specified common dataset for a defined period of time. The project is divided into two phases: Tier 1 will utilize the Modern-Era Retrospective analysis for Research and Applications, version 2 (MERRA-2 reanalysis from January 1980 to June 2017 and will be used as a baseline for all subsequent comparisons. Participation in Tier 1 is required. Tier 2 will be optional and include sensitivity studies designed around specific science questions, such as reanalysis uncertainty and climate change. High-resolution reanalysis and/or model output will be used wherever possible. Proposed metrics include AR frequency, duration, intensity, and precipitation attributable to ARs. Here, we present the ARTMIP experimental design, timeline, project requirements, and a brief description of the variety of methodologies in the current literature.

Long-term changes to flood conditions due to varying management strategies, Rock River, WI
Fredrick, K. C.
2015-12-01
The Rock River is a 300-mile tributary of the Mississippi River in southern Wisconsin. Its source is a protected migratory bird habitat called the Horicon National Wildlife Refuge. Below the refuge, the Rock River flows through mostly rural, agricultural areas, with wide floodplain of mixed land use. Between the dam at Horicon and a hydroelectric dam in Watertown, WI, lie the townships of Lebanon, Ashippun, and Ixonia. These rural townships boast productive agricultural lands of mostly corn, soybeans, and alfalfa. Large portions of their land are within the floodplain, underlain by vast expanses of outwash sands and gravels, glaciolacustrine deposits, and tills. Throughout the region, spring floods are common from snowmelt and spring rain. These annual floods may be exacerbated by frozen ground and slow infiltration, making it an accepted part of life for residents. Over the last 8 years, and possibly as many as 20, this segment of the Rock River has seen an increase in flooding both in periodicity and retention of flood waters. Due to the delicate habitat of the wildlife refuge and the commissioned hydroelectric installation at the upper dam in Watertown, the residents and local governments of the Lebanon/Ashippun/Ixonia segment of the river have mostly been left to their own devices to monitor and manage flood events. Lebanon Township has been recording water levels for several years. Recent events at the hydroelectric plant seem to indicate that it may be playing a more important role in the flooding. High water events and flood retention do not correlate well with precipitation for the region. It appears that releases at the dam, or periods of water retention, are driving the long flooding periods upstream. Negative impacts to the region from the flooding include property damage, loss of arable land, and environmental effects.

Hydroelectric developments in Nunavik : update on impact benefit agreements
Energy Technology Data Exchange (ETDEWEB)
Aatami, P. [Makivik Corp., Makivik, NF (Canada)
2004-07-01
The Partnership Agreement on Economic and Community Development in Nunavik is intended to accelerate development of natural resources in Nunavik and promote autonomy of the Inuit regional organizations. This can be accomplished through hydroelectric projects, mining, sport hunting, outfitting and tourism. In recent years, activities in these domains have raised fundamental questions pertaining to the advantages and disadvantages of resource development. The role that the Impact Benefit Agreement has on business opportunities has been examined more closely. The results of the Impact Benefit Agreement and its implication for the Cree Nation and hydro development in untapped regions of northern Quebec were described along with the role of the parties in financing future projects. An overview of the costs, benefits and considerations for hydro opportunities in northern Quebec was presented with reference to the electricity grid and the incentives for large investment. 1 fig.

Influence of the Three Gorges Project on saltwater intrusion in the Yangtze River Estuary
An, Qiang; Wu, Yanqing; Taylor, Shauna; Zhao, Bin
2009-02-01
The Three Gorges Project (TGP) is a transcentury project that has aroused world attention. It is expected that the flow velocity and runoff of the Yangtze River will be changed after the project has been accomplished. Consequently, however, the ecological environment in the Yangtze River Basin, particularly in the estuary region, will be affected. Salinity intrusion into the Yangtze River estuary, in general, is mostly affected by the Yangtze River discharge and its external tidal level. This paper focuses on examining the influence of changes in runoff on salinity value. The question, to which should be paid attention is: how is the interaction between changes in runoff of the Yangtze River and salinity distribution in the Yangtze River estuary, China? In this research, a three-dimensional model has been used to identify the effects of runoff change on salinity distribution. The drawn conclusion is that the change of salinity is influenced by discharge variation. Positive and negative impacts of TGP would both turn up but in different period. In sum, TGP is in favor of restraining saltwater intrusion. Nevertheless a suitable method should be found to resolve its negative influences.

Impact on the aquatic environment of hydro-peaking in hydroelectric plants
International Nuclear Information System (INIS)
Sabaton, C.; Lauters, F.; Valentin, S.
1996-01-01
There are a number of types of hydroelectric installations on French rivers. Some of these intermittently turbine water stored in dammed reservoirs, in order to use available reserves at the most opportune moment for power generation. These plants, run under 'hydro-peaking' management procedures, cause variations in discharge in river sections downstream of the restitution, on a daily or weekly scale. To answer questions concerning the impact of such variations in discharge on the aquatic environment, EDF launched a research program aimed at describing and better understanding the physical and biological phenomena related to hydro-peaking and assessing the possible impact of this type of plant management on French streams. Seven sites subjects to hydro-peaking were studied on rivers with mean flow rates lower than 20 m 3 /s (which corresponds to over 65 % of EDF hydro-peaking sites). Four themes in particular were examined: hydraulic characterization of hydro-peaking, modifications in thermal regime and water quality, response of benthic invertebrates and response of fish populations to hydro-peaking. For fish as well as for invertebrates, the role of the base discharge - in the absence of peaking flow - and that of the morphology of the river bed (and, in particular, the presence of shelter for fish) during periods of strong discharge were clearly highlighted. Impact assessment requires a precise diagnosis of the state of biocenoses. To carry out such a diagnosis, one must reason in terms of species, life phase (particularly the most sensitive phases) and population structure as well as the type of stream and the faunizone involved. A risk assessment is possible by means of simultaneous study of the morphology of the river bed and the response of the signal generated by hydro-peaking in terms of hydrology and physical characteristics downstream of the restitution.

Joint Venture Modes of Water Conservancy and Hydroelectric Engineering
Directory of Open Access Journals (Sweden)
Zhiding Chen
2013-07-01
Full Text Available With the long construction period, the giant scope and complex technology, water conservancy and hydroelectric engineering construction has large investment. In the fully competitive water conservancy and hydropower project construction contracting market, it is almost impossible for a company to contract with a water conservancy and hydropower project independently. Therefore, water conservancy and hydropower project construction can be contracted by several construction companies together, to play each company's strengths, lower offer, improve project quality, shorten the construction period and win the competition. In this paper, we started from the definition of Joint Venture, summed up the forms of Joint Venture in water conservancy and hydropower engineering, proposed that the JV modes can be divided into domestic and international union, tight mode, half-tight mode, loose mode, incorporation and consortium. Furthermore, we analyzed the advantages and disadvantages of Joint Venture. Put forward that the JV can relieve the owner from interfacial administrative work, reduce risk of engineering, and raise the success rate of engineering contract, improve the correctness of price and increase the opportunity of project contracting, Learn from other members, enhance technology and management and make full use of idle resources

Seyler, J.; Evers, J.; McKinley, S.; Evans, R.R.; Prevost, G.; Carson, R.; Phoenix, D.
1996-01-01
This project and publication is the result of a collaborative effort by other Large River Ecosystem Unit of Northeast Science (NEST), Ontario Hydro in Kapuskasing, and the New Post First Nation in Cochrane, Ontario, designed to investigate potential solutions to minimize or eliminate the problem of trapped lake sturgeon in the Adam Creek Diversion. The Adam Creek Dam is used to divert excess water from the Mattagami River hydroelectric complex which consists of the Little Long, Smoky Falls, Harmon and Kipling generating stations. The lake sturgeon entrainment problem in the area was discovered in 1990. Potential solutions to the problem include the redirection of flows to mainstream, the placement of a rope barrier, electrical deterrents, physical/electrical guidance systems, sound deterrents, gate modifications, and the continued relocation of fish. The advantages and disadvantages of each of these potential solutions are discussed. Results of the analysis indicated that perceptual and physical barriers have the greatest potential to minimize lake sturgeon entrainment in Adam Creek. 25 refs., 2 tabs., 3 figs., 6 appendices

Urban Panorama Tourism Planning A View From River Tour Course In Post-Three Gorges Era
Directory of Open Access Journals (Sweden)
Wei Jia Tian
2012-12-01
Full Text Available The upstream cities of Yangtze River have been witnessing significant transforming since the beginning of the construction of the Three Gorges hydroelectric dam project. Chongqing Port Authority had its opportunity to alternate the river tourism strategy from being the upstream terminal of the golden route into creating a particular cruise course towards perceiving the panorama of continuous elevation of mountainous city, at the same time, promoting the renovation of the urban design so as to revival the typical mountain-river vista. This paper bases on the panoramic research of Chongqing peninsula; discusses the characteristic aspects of the three-dimension sightseeing of the mountainous city on the cruise route, which widely exists in the Three Gorges region as well. And this method is different from the two dimensional approach of skyline analysis which is more suitable for the topographic area. The achieved work can offer the tourism-related sectors a sustainable assistance to deal with “tourbanism” topics in the urban regeneration process in the Three Gorges regions.

Full Text Available The ever-growing diffusion of renewables as electrical generation sources is forcing the electrical power system to face new and challenging regulation problems to preserve grid stability. Among these, the primary control reserve is reckoned to be one of the most important issues, since the introduction of generators based on renewable energies and interconnected through static converters, if relieved from the primary reserve contribution, reduces both the system inertia and the available power reserve in case of network events involving frequency perturbations. In this scenario, renewable plants such as hydroelectric run-of-river generators could be required to provide the primary control reserve ancillary service. In this paper, the integration between a multi-unit run-of-river power plant and a lithium-ion based battery storage system is investigated, suitably accounting for the ancillary service characteristics as required by present grid codes. The storage system is studied in terms of maximum economic profitability, taking into account its operating constraints. Dynamic simulations are carried out within the DIgSILENT PowerFactory 2016 software environment in order to analyse the plant response in case of network frequency contingencies, comparing the pure hydroelectric plant with the hybrid one, in which the primary reserve is partially or completely supplied by the storage system. Results confirm that the battery storage system response to frequency perturbations is clearly faster and more accurate during the transient phase compared to a traditional plant, since time delays due to hydraulic and mechanical regulations are overpassed. A case study, based on data from an existing hydropower plant and referring to the Italian context in terms of operational constraints and ancillary service remuneration, is presented.

Numerical Simulation of Missouri River Bed Evolution Downstream of Gavins Point Dam
Sulaiman, Z. A.; Blum, M. D.; Lephart, G.; Viparelli, E.
2016-12-01
The Missouri River originates in the Rocky Mountains in western Montana and joins the Mississippi River near Saint Louis, Missouri. In the 1900s dam construction and river engineering works, such as river alignment, narrowing and bank protections were performed in the Missouri River basin to control the flood flows, ensure navigation and use the water for agricultural, industrial and municipal needs, for the production of hydroelectric power generation and for recreation. These projects altered the flow and the sediment transport regimes in the river and the exchange of sediment between the river and the adjoining floodplain. Here we focus on the long term effect of dam construction and channel narrowing on the 1200 km long reach of the Missouri River between Gavins Point Dam, Nebraska and South Dakota, and the confluence with the Mississippi River. Field observations show that two downstream migrating waves of channel bed degradation formed in this reach in response to the changes in flow regime, sediment load and channel geometry. We implemented a one dimensional morphodynamic model for large, low slope sand bed rivers, we validated the model at field scale by comparing the numerical results with the available field data and we use the model to 1) predict the magnitude and the migration rate of the waves of degradation at engineering time scales ( 150 years into the future), 2) quantify the changes in the sand load delivered to the Mississippi River, where field observations at Thebes, i.e. downstream of Saint Louis, suggest a decline in the mean annual sand load in the past 50 years, and 3) identify the role of the main tributaries - Little Sioux River, Platte River and Kansas River - on the wave migration speed and the annual sand load in the Missouri River main channel.

Ultra-low-head hydroelectric technology: A review
Energy Technology Data Exchange (ETDEWEB)
Zhou, Daqing; Deng, Zhiqun (Daniel)
2017-10-01
In recent years, distributed renewable energy-generation technologies, such as wind and solar, have developed rapidly. Nevertheless, the utilization of ultra-low-head (ULH) water energy (i.e., situations where the hydraulic head is less than 3 m or the water flow is more than 0.5 m/s with zero head) has received little attention. We believe that, through technological innovations and cost reductions, ULH hydropower has the potential to become an attractive, renewable, and sustainable resource. This paper investigates potential sites for ULH energy resources, the selection of relevant turbines and generators, simplification of civil works, and project costs. This review introduces the current achievements on ULH hydroelectric technology to stimulate discussions and participation of stakeholders to develop related technologies for further expanding its utilization as an important form of renewable energy.

Small hydro-electric potential: west Poverty Bay region
Energy Technology Data Exchange (ETDEWEB)
1981-07-01
This study has identified six schemes in the Bay of Plenty Electric Power Board area and two in the Poverty Bay Electric Power Board area, of which five and one, respectively, are below the economic limit of $2400/kW suggested by the Ministry of Works and Development as of December 1979. Of these, only three appear both economically and environmentally acceptable. The Takaputahi and Torere schemes are not likely to proceed if the Ministry of Works and Development continue with their plans to develop the Motu River. Furthermore, the Motu Falls scheme is unlikely to proceed for environmental reasons. The schemes identified are not very attractive on the national scale and could not be justified on local terms. However, a detailed feasibility study of the Takaputahi/Torere diversion should be undertaken prior to a decision being made to proceed with the Motu development, or if the proposals are dropped. The present low load and slow growth of the area is such that prior to a small hydro-electric scheme being built, there would need to be an established demand for power.

West Kootenay Power Ltd. : Application to sell its hydroelectric generation assets : Decision
International Nuclear Information System (INIS)
Ostergaard, P.; Bradley, P.G.; Clemenhagen, B.L.
2001-01-01
An investor-owned electric utility providing wholesale and retail service in the West Kootenay and South Okanagan regions of British Columbia, West Kootenay Power Ltd. (WKP) sought the approval from the British Columbia Utilities Commission to sell the four hydroelectric power plants and related facilities to Kootenay River Power Corporation (KRP), and for the purchase by WKP of the output of these plants under a 60-year power purchase agreement. The four hydroelectric plants have a combined rated capacity of approximately 214 MW. Most of the energy and capacity needs of WKP are met via power purchase contracts and agreements, as winter peak loads approach 700 MW. As a result of share purchases, KRP would be 50 per cent owned by each of a provincial Crown Corporation, Columbia Power Corporation (CPC) and a wholly-owned subsidiary of the Columbia Basin Trust (CBT), CBT Energy Inc., if the transactions are allowed to proceed. Three principal agreements are of interest: the Asset Transfer Agreement (ATA), the Share Purchase Agreement (SPA), and the Power Purchase Agreement (PPA). During the review process, two main issues warranted special consideration: the treatment of the proceeds of the sale of assets, and the statutory parameters used by the Commission for the adjudication of the Application. The Application was submitted March 22, 2001, and the public hearing process began May 29, 2001. This Application is unique, in that it contains three agreements that would each require a separate review, but WKP requested that the agreements be considered in their aggregate. The Commission complied, and decided to deny the Application. Unless the terms of the sale are restructured, the transfer of assets to Kootenay River Power Corporation will not be approved by the Commission. Within one month of the date of this decision, WKP is to notify the Commission of its intentions, since it had signified that it would not proceed with the sale unless WKP shareholder receives 100

Hood River Conservation Project load analysis
Energy Technology Data Exchange (ETDEWEB)
Stovall, T.K.
1987-11-01
As a part of the Hood River Conservation Project (HRCP), 314 homes were monitored to measure electrical energy use. The total electrical load, space heating load, water heating load (in about 200 homes), wood-stove heat output (in about 100 homes), and indoor temperature were monitored. Data were collected for one full year before and one full year after these homes were retrofit with conservation measures. Local weather information was also collected on a 15-min basis. This data base was used to evaluate the load savings attributable to HRCP. Two methods of weather normalization were used and showed close agreement. The weather-normalized diversified residential load savings on the Pacific Power and Light system and Hood River area peak days were >0.5 kW/household. The average spring, summer, and fall savings were much smaller, <0.1 kW/household. The load factor for the diversified residential load decreased following the conservation retrofit actions. 11 refs., 40 figs., 13 tabs.

SHIKASHIO, L.A.
2000-01-01
The Office of River Protection (ORP) is implementing the River Protection Project (RPP) using two prime contractors. CH2M Hill Hanford Group, Inc. (CHG) is responsible for operating the existing tank system, delivering the waste feed to the waste treatment plant, and managing the resulting low- and high-level glass waste ''product'' through a performance-based fee type contract. A separate prime contractor will be responsible for designing, constructing and commissioning of a new Waste Treatment and Immobilization Plant (WTP), and preparing the waste for ultimate disposal. In addition to the prime contractors and their interfaces, the River Protection Project is being conducted on the Hanford Site, which is under the management of another DOE organization, DOE Richland Field Office (DOE-RL). The infrastructure and utilities are provided by DOE-RL, for example. In addition, there are multiple other technical interfaces with federal, state and other regulatory agencies that influence the management of the activities. This paper provides an overview of the approach employed by ORP to identify, coordinate, and manage the technical interfaces of RPP. In addition, this paper describes the approach and methodologies used to: Establish an overall framework for interface management. Establish the requirements for defining and managing interfaces for the prime contractors and DOE. Contractually requiring the prime contractors to control and manage the interfaces

Changes in groundwater recharge under projected climate in the upper Colorado River basin
Tillman, Fred; Gangopadhyay, Subhrendu; Pruitt, Tom
2016-01-01
Understanding groundwater-budget components, particularly groundwater recharge, is important to sustainably manage both groundwater and surface water supplies in the Colorado River basin now and in the future. This study quantifies projected changes in upper Colorado River basin (UCRB) groundwater recharge from recent historical (1950–2015) through future (2016–2099) time periods, using a distributed-parameter groundwater recharge model with downscaled climate data from 97 Coupled Model Intercomparison Project Phase 5 climate projections. Simulated future groundwater recharge in the UCRB is generally expected to be greater than the historical average in most decades. Increases in groundwater recharge in the UCRB are a consequence of projected increases in precipitation, offsetting reductions in recharge that would result from projected increased temperatures.

The Use of Advanced Hydroelectric Turbines to Improve Water Quality and Fish Populations
International Nuclear Information System (INIS)
Brookshier, P.A.; Cada, G.F.; Flynn, J.V.; Rinehart, B.N.; Sale, M.J.; Sommers, G.L.
1999-01-01
Hydroelectric power contributes about 10 percent of the electrical energy generated in the United States, and nearly 20 percent of the worlds electrical energy. It is a renewable energy source that can contribute significantly to reduction of greenhouse gases by offsetting conventional carbon-based electricity generation. However, rather than growing in importance, hydroelectric generation has actually declined in recent years, often as a consequence of environmental concerns centering around (1) restriction of upstream and downstream fish passage by the dam, and (2) alteration of water quality and river flows by the impoundment. The Advanced Hydropower Turbine System (AHTS) Program of the U.S. Department of Energy is developing turbine technology which would help to maximize global hydropower resources while minimizing adverse environmental effects. Major technical goals for the Program are (1) the reduction of mortality among turbine-passed fish to 2 percent or less, compared to current levels ranging up to 30 percent or greater; and (2) development of aerating turbines that would ensure that water discharged from reservoirs has a dissolved oxygen concentration of at least 6 mg/L. These advanced, environmentally friendly turbines would be suitable both for new hydropower installations and for retrofitting at existing dams. Several new turbine designs that have been developed in the initial phases of the AHTS program are described

1987-01-01
The Cat Arm Dam hydroelectric development in Newfoundland comprises 10 dams, three tunnels, two canals and a 127 MW powerhouse. The scheme develops 127 MW from 380.5 m of head and comprises: ten dams of varying heights up to 53 m; a bathtub type overflow spillway 330 m in length; a 230 m long inverted U-shaped diversion tunnel; an 800 m long, inverted U-shaped low pressure forebay tunnel; two bog and rock cut tunnels leading to and from the forebay tunnels; a surface powerhouse containing two Pelton turbines; and a 178 km long, 230 kV transmission line. An overview is provided of the environmental assessment, project impacts, and cost of environmental protection associated with the project. Impacts were centered around fish and aquatic life in the created reservoir and downstream of the powerhouse, loss of ungulate (moose and caribou) habitat due to flooding, loss of forestry resources due to flooding, and the disturbance of land during construction. The overall cost of environmental protection was $7,977,000, only 2% of the total project cost. 17 refs., 1 tab

Full Text Available On the basis of studying of water funds, of the regimes and characteristics of flow of the Prut, of those internal larger and smaller ones, taking into consideration what basins exist and the ones with perspective can demonstrate the hydroenergetical potential values of Republic of Moldova for the current time and on long-time period. The basic variant of the scheme of arrangement on the Prut on the basis of the requirements of today’s impact with the environment, the ecologic flows, hydroenergetical equipments chosen for the parameters of sufficient operation, and the hidrotehnical unit must have an appearance of a complex utilization. The assurances of the flows and head of the hydro-electric plants with operation in cascade on rivers is caused by the strength of the given data and the hydrologic calculations after interstate normatives applied now. Suggested scheme foresees to build dozens of hydro-electric plants with small head on the Prut from which an unit functions as the minimum on the ecologic flow. The potential of the basins of existing accumulation on little rivers must be capitalized first because it requires only the power equipment. Prof. D.

Sediment cores were sampled in the estuary of the Nelson and Churchill Rivers in western Hudson Bay, as well as in the estuary of the Moisie and Sainte-Marguerite Rivers in Gulf of St. Lawrence in order to evaluate the impact of hydroelectric dams on the sedimentary regime of these estuaries. The gravity cores at the mouth of the Nelson River recorded several cm-thick rapidly deposited layers with a reverse to normal grading sequence, indicating the occurrence of hyperpycnal flows generated by major floods during the last few centuries. These hyperpycnal flows were probably caused by ice-jam formation, which can increase both the flow and the sediment concentration following the breaching of such natural dams. Following the construction of hydroelectric dams since the 1960s, the regulation of river discharge prevented the formation of hyperpycnal flows, and hence the deposition of hyperpycnites in the upper part of the cores. In the core sampled in the estuary of the Churchill River, only one hyperpycnite was recorded. This lower frequency may be due to the enclosed estuary of the Churchill River, its weaker discharge and the more distal location of the coring site.In the Gulf of St. Lawrence, grain size measurements allowed the identification of a major flood around AD 1844±4 years in box cores from both the Sainte-Marguerite and Moisie Rivers, whereas a drastic decrease in variations in the median grain size occurred around AD ~1900 in the estuary of the Sainte-Marguerite River, highlighting the offshore impact of the SM1 dam construction in the early 1900s. Furthermore, sedimentological variations in the box cores from both estuaries have been investigated by wavelet analysis and the sharp disappearance of high frequencies around AD 1900 in the estuary of the dammed river (Sainte-Marguerite River), but not in the estuary of the natural river (Moisie River), also provides evidence of the influence of dams on the sedimentary regime of estuaries.

Such potential transformative information motivates the investigation of our ability to ingest the associated data into continental-scale models of terrestrial hydrology. In preparation for the expected SWOT observations, an inter-comparison of continental-scale river models is being performed. This comparison experiment focuses on four of the world's largest river basins: the Amazon, the Mississippi, the Niger, and the Saint-Lawrence. This ongoing project focuses on two main research questions: 1) How can we best prepare for the expected SWOT continental to global measurements before SWOT even flies?, and 2) What is the added value of including SWOT terrestrial measurements into global hydro models for enhancing our understanding of the terrestrial water cycle and the climate system? We present here the results of the second year of this project which now includes simulations from six numerical models of rivers over the Mississippi and sheds light on the implications of various modeling choices on simulation quality as well as on the potential impact of SWOT observations.

Reaching for 100% participation in a utility conservation programme: the Hood River project
Energy Technology Data Exchange (ETDEWEB)
Hirst, Eric
1989-04-01
The Hood River Conservation Project (HRCP) was a major residential retrofit demonstration project. The project was intended to install as many cost-effective retrofit measures in all electrically heated homes in Hood River, OR, USA. To achieve 100% participation, HRCP offered a package of 'super' retrofit measures and paid for installation of these measures. Almost all (91%) of the eligible households participated, in stark contrast to the much lower participation levels achieved in other residential conservation programmes. Also, unlike other programmes, HRCP attracted larger fractions of traditionally hard-to-reach groups: low-income households; occupants of multifamily units; and renters. The key factors leading to this phenomenal success include: the offer of free retrofits; determination on the part of staff to enlist every eligible household; the use of community-based marketing approaches; and reliance on extensive word-of-mouth among Hood River residents.

James Bay II, the projected Canadian hydroelectric power plant of gigantic dimensions, is to deliver its electricity to Europe: in the USA, opposition to power imports from James Bay is growing. Its realization means the flooding of an area as big as the Federal Republic of Germany; the native territory and hunting grounds of the Cree indians would be inundated. The interests of the European power industry in the James Bay project and the consequences for Europe are described in an appendix (EQHHPP project, project management Hydro-Quebec and Ludwig Boelkow Foundation, hydrogen production through electrolysis, methods for transporting hydrogen to Hamburg).

Chamera Hydroelectric Project was selected by National Hydroelectric Power Corporation (NHPC) as a pilot project for accelerated development of hydro-power in the country. This project was considered to have certain distinct specialties from different aspects in comparison with other projects. In the first place, the field investigation for the project was completed in a record time of only eight months by deploying the most modern techniques. Secondly, Chamera was the first NHPC project with external aid both technically and financially. The third and most important of all the specialties was in the planned reduction of construction period to 6 years from the original estimate of 8 years. Such reduction of gestation period was considered to be the direct outcome of modern method of management, monitoring and improved imported technology. The investment decision in the project was taken in April '84 with an estimated cost of energy at busbar 44.12 paise/unit exclusive of return on equity capital and royalty payable to the home state. The all inclusive rate of power was estimated 75.86 paise/unit. (author). 4 tabs

Situated in the central part of China, the Han River Basin is undergoing rapid social and economic development with some human interventions to be made soon which will profoundly influence the water environment of the basin. The integrated MIKE 11 model system comprising of a rainfall-runoff model (NAM), a non-point load evaluation model (LOAD), a hydrodynamic model (MIKE 11 HD) and a water quality model (ECOLab) was applied to investigate the impact of the Middle Route of the South-North Water Diversion Project on the Han River and the effectiveness of the 2 proposed mitigation projects, the 22 wastewater treatment plants (WWTPs) and the Yangtze-Han Water Diversion Project. The study concludes that business as usual will lead to a continuing rapid deterioration of the water quality of the Han River. Implementation of the Middle Route of the South-North Water Diversion Project in 2010 will bring disastrous consequence in the form of the remarkably elevated pollution level and high risk of algae bloom in the middle and lower reaches. The proposed WWTPs will merely lower the pollution level in the reach by around 10%, while the Yangtze-Han Water Diversion Project can significantly improve the water quality in the downstream 200-km reach. The results reveal that serious water quality problem will emerge in the middle reach between Xiangfan and Qianjiang in the future. Implementation of the South-North Water Diversion Project (phase II) in 2030 will further exacerbate the problem. In order to effectively improve the water quality of the Han River, it is suggested that nutrient removal processes should be adopted in the proposed WWTPs, and the pollution load from the non-point sources, especially the load from the upstream Henan Province, should be effectively controlled.

Risk assessment of hydro projects in the face of climate change - a case study
International Nuclear Information System (INIS)
Cheng, W.; Kilduff, T.
2008-01-01
As the IPCC's Climate Change 2007 report made clear, warming of the Climate System is unequivocal. It is also clear that warming of the land surface can significantly affect the hydrological systems of snow-fed rivers. Thus, it is prudent to consider the potential impacts of climate change when conducting cost-benefit analysis of hydro-electric system capital improvements. This paper evaluates the benefits to Seattle City Light, Seattle's municipal utility, of an upgrade to one of its hydro-electric projects, not on the basis, as is common, of historical flow data, but on the basis of modeled flows under a specific climate change scenario. Another novelty of the paper is that the analysis relies not on one 'normal' or average flow, but on an ensemble of flows that reflect the range of hydro conditions that might be anticipated under the climate scenario. Although the nature of the anticipated impacts of climate in the Northwest are such that the results are not markedly different from ignoring them, the paper raises a number of interesting issues that such analysis should typically address.

Senecal, P.; Egre, D.
1993-01-01
The LaGrande hydroelectric project in northwest Quebec, originally begun in 1972, was blocked by the Cree Indians and a negotiated settlement was reached in 1975 to continue it in exchange for compensation, land rights, and other matters. The James Bay and Northern Quebec Agreement contained provisions regulating the use of land and aimed at preserving the traditional Cree way of life. Other complementary agreements were signed in the 1980s. The impact of river-system modifications on wildlife harvesting and the effect of access roads on Cree communities are discussed. Flooding of hunting lands affected some traplines, and the low productivity of shore habitats and the high levels of mercury in some fish have greatly limited use of the LaGrande reservoirs for other purposes. Stream navigation at some communities was made more difficult because of changed river flows. The impact of the roads has been more positive, since the roads have facilitated trade and reduced local prices of many goods, and made wildlife harvesting easier and more evenly distributed. An income security program for hunters, fishers, and trappers has helped preserve a traditional lifestyle. A sharp increase in salary income, indicating consolidation of the employment market in the region, is the most significant economic impact of the LaGrande project agreement. 6 refs

River damming and building of hydroelectric power plants interrupt the reproductive migration routes and change the major physicochemical parameters of water quality, with drastic consequences for populations of migratory fishes. The goal of this study was to evaluate proliferation and cell death during spermatogenesis and serum profiles of sex steroids in Prochilodus argenteus, from the São Francisco River, downstream from the Três Marias Dam. A total of 257 adult males were caught quarterly during a reproductive cycle in two sites: the first 34 km of the river after the dam (site 1) and the second 34-54 km after the dam (site 2), after the confluence with a tributary, the Abaeté River. Seasonal changes in the testicular activity associated with morphometric analyses of germ cells as well as proliferation and testicular apoptosis support a more active spermatogenesis in fish from site 2, where higher levels of sex steroids and gonadosomatic index (GSI) were also found. In site 1, fish presented low serum levels of testosterone, 17β-estradiol and 17α-hydroxyprogesterone and a low GSI during gonadal maturation. Spermatogonial proliferation (PCNA) and apoptosis (TUNEL) were more elevated in fish from site 1, but spermatocytes were mainly labelled in fish from site 2. Overall, these data demonstrate changes in testicular activity and plasma sex steroids in a neotropical teleost fish living downstream from a hydroelectric dam, supplying new data on fish reproduction in regulated rivers. Moreover, morphometric analyses associated with sex steroids profiles provide reliable tools to assess fish spermatogenesis under environmental stress conditions.

Africa's hydroelectric power plants are not able to perform at greater than 30 per cent of their installed capacity, despite the fact that Africa has abundant hydroelectric resources. Droughts and floods attributed to climate change are presenting challenges to the effective management and distribution of hydroelectric power supplies. This paper identified climate change-related barriers against hydroelectric power development in Africa. Case studies of 3 hydroelectric power projects in Nigeria were considered. Rainfall intensity data for a 25-year period were analyzed. The study showed that while the hydroelectric power plants are capable of supplying more power, most dams in Africa are prone to erosion and flash flooding. The sedimentation of reservoirs and natural lakes are also posing significant water management problems. Redesigns are needed in order to reduce risk. The new hydroelectric projects should be designed to ensure that environmental impacts are minimized. A river basin management approach was recommended in order to improve industrial water supplies, power generation, and recreational aspects of waterways. 11 refs., 2 tabs.

Countries growing rates are directly related to energy production. Therefore, developed and developing nations are focused on hydropower and dam construction; on the contrary dam removal practices are significantly different among nations, demonstrating the former group a lesser interest on removing structures. Chiles hydropower generation corresponds to 50% of the current grid, having a potential capacity to double the current situation. Thus: ¿What tools can we apply to assess the potential impacts on our rivers? The goal of this project is to study two different reaches located in two separates streams in Central Chile. The Aconcagua River represents a mountain stream (i.e. steep, narrow, and confined) subject to the operation of a hydroelectric system composed by five diversion hydropower plants built during the 90`s. The Rapel River reach corresponds to the last 10km upstream to the outlet; it is a mild and wide stream that includes the gravel-sand transition. The Rapel dam operates about 25km upstream this second reach that is characterized by an 112m wall built in 1968. The Aconcagua hydropower system was characterized within a GIS environment and a morphological response conceptual model applied. The model uses two indexes to evaluate changes in i) channel forming discharge and ii) sediment supply. The provided response shows the trends and magnitudes of the changes, based in eighth possible directions for ten morphological responsible variables. The Rapel river system was evaluated differently and sampling of sediments characteristics (D50 and armour index), discharge index for both before and after the dam operation, Morphological Quality Index (IQM) and an analysis of aerial photography time series were performed. Results showed that the hydrology indicator impacts for the Aconcagua system were more severe than the impacts on sediments transport (typically the case for diversion type hydropower). A fine armour layer was found within the Rapel river site

Full Text Available This study evaluated the life cycle greenhouse gas (GHG emissions from different hydroelectricity generation systems by first performing a comprehensive review of the hydroelectricity generation system life cycle assessment (LCA studies and then subsequent computation of statistical metrics to quantify the life cycle GHG emissions (expressed in grams of carbon dioxide equivalent per kilowatt hour, gCO2e/kWh. A categorization index (with unique category codes, formatted as “facility type-electric power generation capacity” was developed and used in this study to evaluate the life cycle GHG emissions from the reviewed hydroelectricity generation systems. The unique category codes were labeled by integrating the names of the two hydro power sub-classifications, i.e., the facility type (impoundment (I, diversion (D, pumped storage (PS, miscellaneous hydropower works (MHPW and the electric power generation capacity (micro (µ, small (S, large (L. The characterized hydroelectricity generation systems were statistically evaluated to determine the reduction in corresponding life cycle GHG emissions. A total of eight unique categorization codes (I-S, I-L, D-µ, D-S, D-L, PS-L, MHPW-µ, MHPW-S were designated to the 19 hydroelectricity generation LCA studies (representing 178 hydropower cases using the proposed categorization index. The mean life cycle GHG emissions resulting from the use of I-S (N = 24, I-L (N = 8, D-µ (N = 3, D-S (N = 133, D-L (N = 3, PS-L (N = 3, MHPW-µ (N = 3, and MHPW-S (N = 1 hydroelectricity generation systems are 21.05 gCO2e/kWh, 40.63 gCO2e/kWh, 47.82 gCO2e/kWh, 27.18 gCO2e/kWh, 3.45 gCO2e/kWh, 256.63 gCO2e/kWh, 19.73 gCO2e/kWh, and 2.78 gCO2e/kWh, respectively.

Full Text Available Hydroelectric power plants are considered strategic for the country when considering their relevance and impact on other sectors of the economy. However, the dynamics of the operation of a plant, its support structure and power generation activities can cause impacts on the environment, which must be constantly monitored in order to mitigate any environmental risks. The purpose of this study is to examine the partnership relations between a plant by menas of the creation of a department within the environmental management and universities and research institutes to identify specific partnerships in environmental management and hydroelectric plants. Six projects have been selected for analysis, four of them related to projects with universities and two related to cooperation with research institutes. The focus of the analysis was restricted to the main points observed in the management of these partnerships, which are: (a motivation for establishing partnerships, (b the composition of the estimated costs for implementing these partnerships, (c the difficulties of reconciling technical management and financial management, and (d the measurement of results and contributions from these interactions. Administrative practices of management of partnerships were also analyzed in the stages preceding cooperation for cooperation and further cooperation. Although other such studies are needed to strengthen the findings presented, one can conclude that the purposes of the establishment of cooperation in environmental management differ from those observed in other fields of knowledge such as engineering and biotechnology, for example.

2004-02-01
The goal of the Wind River project is to preserve, protect and restore Wind River steelhead. In March, 1998, the National Marine Fisheries Service listed the steelhead of the lower Columbia as 'threatened' under the Endangered Species Act. In 1997, the Washington Department of Fish and Wildlife rated the status of the Wind River summer run steelhead as critical. Due to the status of this stock, the Wind River summer steelhead have the highest priority for recovery and restoration in the state of Washington's Lower Columbia Steelhead Conservation Initiative. The Wind River Project includes four cooperating agencies. Those are the Underwood Conservation District (UCD), United States Geological Service (USGS), US Forest Service (USFS), and Washington State Department of Fish & Wildlife (WDFW). Tasks include monitoring steelhead populations (USGS and WDFW), Coordinating a Watershed Committee and Technical Advisory Group (UCD), evaluating physical habitat conditions (USFS and UCD), assessing watershed health (all), reducing road sediments sources (USFS), rehabilitating riparian corridors, floodplains, and channel geometry (UCD, USFS), evaluate removal of Hemlock Dam (USFS), and promote local watershed stewardship (UCD, USFS). UCD's major efforts have included coordination of the Wind River Watershed Committee and Technical Advisory Committee (TAC), water temperature and water chemistry monitoring, riparian habitat improvement projects, and educational activities. Our coordination work enables the local Watershed Committee and TAC to function and provide essential input to Agencies, and our habitat improvement work focuses on riparian revegetation. Water chemistry and temperature data collection provide information for monitoring watershed conditions and fish habitat, and are comparable with data gathered in previous years. Water chemistry information collected on Trout Creek should, with 2 years data, determine whether pH levels make conditions

This dissertation analyses the rapid industrialisation of the rural Comte de Beauharnois and the adjacent stretch of the Fleuve Saint-Laurent owing to the construction, between 1929 and 1948, of a gigantic canal for hydroelectricity production and navigation by an electricity corporation called the Beauharnois Light Heat and Power (BLH&P). Using principally the archives of the BLH&P---especially its complaints files and its rich photographic record---this thesis argues that this process exemplifies the finance capitalist reorganisation of the society and ecosystems of the Canadian province of Quebec from the 19th century to the Great Depression. In keeping with recent work in environmental history, the transformation of rural landscapes and a river for heavy industry is described as an important dimension of a revolution in modes of production. More specifically, I argue that, in the case under study, the finance-capitalist reorganisation of Quebec revolved around two central and explicit projects, one social and the other environmental: the grouping of most individuals in an industrial working class without control over the means of production and the reorganisation of rural landscapes into reservoirs of modern energy and industrial natural resources.

300 MW Baspa II is India's largest private hydroelectric facility, located at the Baspa River which is an important left-hand tributary to the Sutlej River in the NW Himalaya (India). In this valley the Sangla palaeo-lake has been dammed around 8200 yr BP behind a rock-avalanche dam and Baspa II is located exactly on top of this palaeo-lake. This special location represents a very rare possibility to evaluate the short-term, river load and hydrological parameters measured during the planning and operational stages of Baspa II with the long-term parameters gained from the palaeo-lake sediments from the catchment. Sedimentological and geomorphological investigations of the lacustrine sediments have been used to reconstruct environmental changes during >2500 years of its existence. The Mid-Holocene erosion rates of the Baspa catchment estimated from the volume and duration of deposition of the exposed lake sediments are at 0.7-1.0 mm yr-1, almost identical with the modern erosion rates calculated from river gauge data from Baspa II. Several charcoal layers and charcoal pieces from the uppermost palaeo-lake levels around 5000 cal yr BP might be related to woodland clearance and they possibly represent one of the oldest evidences for human presence in the Baspa Valley during Neolithic time.

Tropical hydroelectric reservoirs generally constitute an appreciable source of methane to the atmosphere. This paper proposes simple mitigation and recovery procedures to substantially reduce atmospheric methane emissions from hydroelectric reservoirs. We aim at transforming existing methane stocks of tropical reservoirs into a clean, renewable energy source. The recovered gas methane may be pumped to large consuming centers, stocked locally and burned in gas turbines to generate electricity during high demand periods, or even purified for transport applications. Our simulations show that the use of biogenic methane may increase considerably the energy supply in countries like Brazil. As a result, it would be possible to reduce the need of additional hydroelectric dams, protecting important pristine biomes, and avoiding the resettlement of villages and indigenous reserves.

Entomological studies conducted in large hydroelectric infrastructure projects are a tool for the prevention and control of vector-borne diseases. These diseases emerge as a consequence of changes made to the terrain that often increase the natural and artificial mosquito larval habitats. Many of these insects are of public health importance and population increases result in an increased risk of disease transmission. The culicine (mosquito) and phlebotomine (sand fly) populations were characterized in the area of the Porce II and Porce III hydroelectric projects of Antioquia between 1990 to 2009. Periodical entomological samplings were made in the area of impact, in the workers camps, and construction sites. Adult specimens were captured with nets, Shannon light traps, CDC light traps, and protected human bait. Mosquito larvae of the following species were identified: Culex coronator, Culex nigripalpus, Culex corniger, Culex quinquefasciatus and Limatus durhami. The most frequently identifiers of larval habitats were low tanks, waste cans, tires, and aquatic plants. Aedes aegypti specimens were captured in only two rural locations from two municipalities within the area of influence. Specimens from the following mosquito genera were captured in forest areas: Aedes, Mansonia, Culex, Psorophora, Wyeomyia, Phonyomyia, Uranotaenia, Haemagogus and Sabethes. The most important mosquito found was Haemogogus janthinomis, an efficient yellow fever vector in Colombia. The area has been endemic for leishmaniasis and in the current study, 20 species of Lutzomyia sand flies, potential vectors, were identified. Among malaria vectors, the most important species found in the area were Anopheles nuneztovari and Anopheles pseudopunctipennis. A wide variety of vectors were discovered in the area of the Porce II and Porce III hydroelectric projects, and many of these were relevant for public health. Further monitoring will be necessary to minimize disease transmission risks among the

Full text: The scientific community of six countries (USA, Kazakhstan, Russia, Georgia, Armenia, and Azerbaijan) has developed the ecological project 'Joint International Researches and Creation of the General System of Radiation and Hydro-chemical Monitoring of Rivers of the Caspian Sea Basin.' The purpose of this project is to investigate and characterized contamination by radionuclides and toxic and chemically hazardous elements and create a valid system of radiation and hydro-chemical monitoring of the main river basins of the Caspian region: the Volga, Ural, Emba and Kura. The basins of these rivers cover large parts of Europe and Asia, including parts of Russia, West Kazakhstan and the South Caucasus and including territories of Georgia, Armenia and Azerbaijan. The total area of the basins of these rivers exceeds combined area of such large European states as France, Spain and Germany, and comprises 1631 sq. km. All these rivers are the main life-supporting water arteries for the region's inhabitants, a population that comprises tens of millions of people Also, the outlets of these rivers determine the condition of the aquatic environment of the Caspian Sea. The ecological condition of the aquatic environment of all the rivers of the Caspian Sea is to a great extent due to contamination, the main components of which are anthropogenic radioactive elements, heavy metals and oil products. At present, information about contamination levels of these rivers is not known and is occasionally contradictory. In this connection there is an obvious need of qualified investigation of contamination levels and its character in the basins of these rivers and in creating a common monitoring system to assess the quality of the aquatic environment. The present project is devoted to this matter. 1. The project provides for the following main tasks: 1. Wide-ranging investigation of the level and character of contamination by radionuclides and toxic elements of the river basins

Damming rivers to construct hydroelectric reservoirs results in a series of impacts on the biogeochemical Hg cycle. For example, modifying the hydrodynamics of a natural watercourse can result in the suspension and transport of Hg deposits in the water column, which represents an exposure risk for biota. The objective of this study was to evaluate the influences of seasonality on the dispersion of total Hg in the Hydroelectric Power Plant (HPP)-Samuel Reservoir (Porto Velho/Brazil). Sampling campaigns were performed during the three following hydrological periods characteristic of the region: low (Oct/2011), ebbing (May/2012), and high (Feb/2013) water. Sediment profiles, suspended particulate matter (SPM), and aquatic macrophytes (Eicchornia crassipes and Oryza spp.) were collected, and their Hg concentrations and isotopic and elemental C and N signatures were determined. The drainage basin significantly influenced the SPM compositions during all the periods, with a small autochthonous influence from the reservoir during the low water. The highest SPM Hg concentrations inside the reservoir were observed during the high water period, suggesting that the hydrodynamics of this environment favor the suspension of fine SPM, which has a higher Hg adsorption capacity. The Hg concentrations in the sediment profiles were ten times lower than those in the SPM, indicating that large particles with low Hg concentrations were deposited to form the bottom sediment. Hg concentrations were higher in aquatic macrophyte roots than in their leaves and appeared to contribute to the formation of SPM during the low water period. In this environment, Hg transport mainly occurs in SPM from the Jamari River drainage basin, which is the primary source of Hg in this environment.

2001-01-01
In 2000, the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) Fisheries Habitat Program implemented stream habitat restoration and protection efforts in the Walla Walla River Basin with funding from Bonneville Power Administration (BPA). The objective of these efforts is to protect and restore habitat critical to the recovery of weak or reintroduced populations of salmonid fish. Six projects, two on Couse Creek, two adjacent properties on Blue Creek, one on Patit Creek, and one property on the mainstem Walla Walla River were part of the exercise. Several thousand native plants as bare-root stock and cuttings were reintroduced to the sites and 18 acres of floodplain corridor was seeded with native grass seed. Pre and post-project monitoring efforts were included for all projects, incorporating methodologies from CTUIR's Draft Monitoring Plan.

One of the great environmental advantage offered by hydro-electricity in northern or temperate climates includes reduced atmospheric emissions. While natural gas plants, from an environmental viewpoint, are thought to be the best fossil fuel option, they emit 18 times more greenhouse gases, at least 60 times more sulfur dioxide and hundreds of times more nitrogen oxides than do hydro-electric systems. The relative SO 2 and greenhouse gas emissions from energy systems in Canada were outlined, and their environmental impacts were described. At the same time, mention was made of other environmental pollutants, such as acid rain, photochemical smog, and particulates that continue to have major impacts on the environment, but were displaced as the focus of attention by greenhouse gases. A study was conducted to determine the effects of extreme biomass decomposition and greenhouse gas emissions from reservoirs. The study showed that at depths of more than 10 centimeters below water surface, organic matter does not contribute to greenhouse gas production, even at 20 degrees C. It was demonstrated that even when maximum biomass decomposition is assumed, a modern natural gas plant would emit 14 times more green house gases than a hydroelectric plant of comparable capacity. 13 refs., 4 tabs., 3 figs

Load rejection test is one of the essential tests that carried out before the hydroelectric generating set is put into operation formally. The test aims at inspecting the rationality of the design of the water diversion and power generation system of hydropower station, reliability of the equipment of generating set and the dynamic characteristics of hydroturbine governing system. Proceeding from different accident conditions of hydroelectric generating set, this paper presents the transient processes of load rejection corresponding to different accident conditions, and elaborates the characteristics of different types of load rejection. Then the numerical simulation method of different types of load rejection is established. An engineering project is calculated to verify the validity of the method. Finally, based on the numerical simulation results, the relationship among the different types of load rejection and their functions on the design of hydropower station and the operation of load rejection test are pointed out. The results indicate that: The load rejection caused by the accident within the hydroelectric generating set is realized by emergency distributing valve, and it is the basis of the optimization for the closing law of guide vane and the calculation of regulation and guarantee. The load rejection caused by the accident outside the hydroelectric generating set is realized by the governor. It is the most efficient measure to inspect the dynamic characteristics of hydro-turbine governing system, and its closure rate of guide vane set in the governor depends on the optimization result in the former type load rejection.

The 500-mile long Green River is the largest tributary of the Colorado River. From its origin in the Wind River Range mountains of western Wyoming to its confluence with the Colorado River in southeastern Utah, the Green River is vital to the arid region through which it flows. Large portions of the area remain near-wilderness with the river providing a source of recreation in the form of fishing and rafting, irrigation for farming and ranching, and hydroelectric power. In the late 1950's and early 1960's hydroelectric facilities were built on the river. One of these, Flaming Gorge Dam, is located just south of the Utah-Wyoming border near the town of Dutch John, Utah. Hydropower operations result in hourly and daily fluctuations in the releases of water from the dam that alter the natural stream flow below the dam and affect natural resources in and along the river corridor. In the present study, the authors were interested in evaluating the potential impacts of hydropower operations at Flaming Gorge Dam on the downstream natural resources. Considering the size of the area affected by the daily pattern of water release at the dam as well as the difficult terrain and limited accessibility of many reaches of the river, evaluating these impacts using standard field study methods was virtually impossible. Instead an approach was developed that used multispectral aerial videography to determine changes in the affected parameters at different flows, hydrologic modeling to predict flow conditions for various hydropower operating scenarios, and ecological information on the biological resources of concern to assign impacts

Full Text Available In the world, river basins often interwoven into two or more states or prefectures and because of that, disputes over water are common. Nevertheless, not all shared river basins are associated with water conflicts. Rivers in Japan and Malaysia play a significant role in regional economic development. They also play a significant role as water sources for industrial, domestic, agricultural, aquaculture, hydroelectric power generation, and the environment. The research aim is to determine the similarities and differences between the Sagami and Muda River Basins in order to have a better understanding of the governance needed for effectively implementing the lessons drawn from the Sagami River Basin for improving the management of the Muda River Basin in Malaysia. This research adopts qualitative and quantitative approaches. Semi-structured interviews were held with the key stakeholders from both basins and show that Japan has endeavored to present policy efforts to accommodate the innovative approaches in the management of their water resources, including the establishment of a river basin council. In Malaysia, there is little or no stakeholder involvement in the Muda River Basin, and the water resource management is not holistic and is not integrated as it should be. Besides that, there is little or no Integrated Resources Water Management, a pre-requisite for sustainable water resources. The results from this comparative study concluded that full support and participation from public stakeholders (meaning the non-government and non-private sector stakeholders is vital for achieving sustainable water use in the Muda River Basin. Integrated Water Resources Management (IWRM approaches such as the introduction of payments for ecosystems services and the development of river basin organization in the Muda River Basin should take place in the spirit of political willingness.

Proposed modifications to the Lower Mokelumne River Project, California: FERC Project No. 2916-004
International Nuclear Information System (INIS)
1993-11-01
This final environmental impact statement (FEIS) has been prepared for the Federal Energy Regulatory Commission (Commission) to consider modifications to the existing Lower Mokelumne River Project (LMRP) (FERC Project No. 2916-004) in California. Chinook salmon and steelhead trout populations in the lower Mokelumne River have experienced recent declines and fish kills associated, in part, with discharges from Camanche Dam. The California Department of Fish and Game and the California Sportfishing Protection Alliance have asked the Commission to investigate and correct these problems. A wide range of different mitigation actions has been proposed by parties participating in the scoping of this proceeding, and staff has evaluated these proposed actions in this assessment. The staff is recommending a combination of flow and non-flow modifications to the existing license, including new minimum flow and minimum pool elevation requirements at Camanche Reservoir, ramping rates on dam releases, interim attraction and out-migrant spike flows, instream habitat improvements, and a series of studies and monitoring to determine feasible means for solving off-site fish passage problems

The closure of two phases of the dam at the Porto Primavera Hydroelectric Plant on the Paraná River flooded a flawed system located in the Municipality of Presidente Epitácio, São Paulo state, favoring the proliferation of aquatic weeds. This study aimed to observe the population of Mansonia humeralis in the area, monitoring the richness, diversity, and dominance of this species both before and during different phases of reservoir flooding as well as evaluate its possible consequences concerning human and animal contact. Adult mosquitoes were collected monthly in the following periods: at the original level, after the first flood, and after the maximum level had been reached between 1997 and 2002. Collection methods used were an aspirator, a Shannon trap, and the Human Attractive Technique. A total of 30,723 mosquitoes were collected, Ma. humeralis accounting for 3.1% in the preflood phase, 59.6% in the intermediate, and 53.8% at maximum level. This species is relevant to public health, since the prospect of continued contact between Ma. humeralis and the human population enhances the dam's importance in the production of nuisance mosquitoes, possibly facilitating the transmission of arboviruses. Local authorities should continue to monitor culicid activity through sustainable entomological surveillance.

Columbia River pathway report: phase I of the Hanford Environmental Dose Reconstruction Project
Energy Technology Data Exchange (ETDEWEB)
1991-07-01
This report summarizes the river-pathway portion of the first phase of the Hanford Environmental Dose Reconstruction (HEDR) Project. The HEDR Project is estimating radiation doses that could have been received by the public from the Department of Energy's Hanford Site, in southeastern Washington State. Phase 1 of the river-pathway dose reconstruction effort sought to determine whether dose estimates could be calculated for populations in the area from above the Hanford Site at Priest Rapids Dam to below the site at McNary Dam from January 1964 to December 1966. Of the potential sources of radionuclides from the river, fish consumption was the most important. Doses from drinking water were lower at Pasco than at Richland and lower at Kennewick than at Pasco. The median values of preliminary dose estimates calculated by HEDR are similar to independent, previously published estimates of average doses to Richland residents. Later phases of the HEDR Project will address dose estimates for periods other than 1964--1966 and for populations downstream of McNary Dam. 17 refs., 19 figs., 1 tab.

The Hood River Conservation Project (HRCP) is a major residential retrofit demonstration project. HRCP is funded by the Bonneville Power Administration (BPA) and run by Pacific Power and Light Company. The project was conducted in the community of Hood River, Oregon, will cost $21 million, and will last for three years (mid-1983 through 1986). Installation of applicable retrofit measures was completed by the end of 1985; data collection, analysis, and report writing will continue through 1986. This report documents the extent to which households participated in HRCP. Differences between participants and eligible nonparticipants are examined. Similarly, differences among participants as a function of when they signed up for HRCP are analyzed. The report also examines the dynamics of program services (i.e., times between audit requests and audit, and between audit and installation of measures). These analyses are based on data from the roughly 3500 Hood River homes eligible for HRCP, 3189 of which received free home energy audits and 2988 of which received HRCP-financed retrofit measures.

Full Text Available The river Tibagi from the city of Londrina, in the years 1970 and 1980 was a subject of much discussion and controversy due to the project of raising its waters to supply the population of the cities of Londrina and region. In articles published in newspapers, especially in the Folha de Londrina, in the 1970s and 1980s, it was identified that, this time, the perception emerged that the river was polluted. Thus, our primary goal in the first part of this research is to investigate how it came to creating this image. Therefore, we used a collection of newspaper clippings about the controversy raised from the waters Tibagi and interviews with Nelson Amanthea civil engineer and agronomist Marcos Antonio Castanheira, both participated in discussions on the project. It was in this period that the ideas of ecology was entered and began to circulate in the city in the late 1970s. In this context, the emergence of the "age of ecology”, allegations and actions to combat pollution started to become more effective and broad, as well as, arose environmental associations, specialized government agencies and specific legislation. Thus, the objective of this research is also investigating the involvement of scientists and institutions in environmental issues through research of river Tibagi that became evident in the late 1980 and early next decade when the University State of Londrina initiated research in Tibagi river basin. Is emphasized the participation of members of the Department of Animal Biology and Plant - UEL, the company Klabin Pulp and Paper, Telêmaco Borba - PR and COPATI - Intermunicipal Consortium of Tibagi Basin, projects and actions in order to promote their recovery.

The Brazilian relief, predominantly composed by small mountains and plateaus, contributed to formation of rivers with high amount of falls. With exception to North-eastern Brazil, the climate of this country are rainy, which contributes to maintain water flows high. These elements are essential to a high hydroelectric potential, contributing to the choice of hydroelectric power plants as the main technology of electricity generation in Brazil. Though this is a renewable source, whose utilized resource is free, dams must to be established which generates a high environmental and social impact. The objective of this study is to evaluate the impact caused by these dams through the use of environmental indexes. These indexes are ratio formed by installed power with dam area of a hydro power plant, and ratio formed by firm power with this dam area. In this study, the greatest media values were found in South, Southeast, and Northeast regions respectively, and the smallest media values were found in North and Mid-West regions, respectively. The greatest encountered media indexes were also found in dams established in the 1950s. In the last six decades, the smallest indexes were registered by dams established in the 1980s. These indexes could be utilized as important instruments for environmental impact assessments, and could enable a dam to be established that depletes an ecosystem as less as possible. (author)

Climate change impacts on high-elevation hydroelectricity in California
Madani, Kaveh; Guégan, Marion; Uvo, Cintia B.
2014-03-01
While only about 30% of California's usable water storage capacity lies at higher elevations, high-elevation (above 300 m) hydropower units generate, on average, 74% of California's in-state hydroelectricity. In general, high-elevation plants have small man-made reservoirs and rely mainly on snowpack. Their low built-in storage capacity is a concern with regard to climate warming. Snowmelt is expected to shift to earlier in the year, and the system may not be able to store sufficient water for release in high-demand periods. Previous studies have explored the climate warming effects on California's high-elevation hydropower by focusing on the supply side (exploring the effects of hydrological changes on generation and revenues) ignoring the warming effects on hydroelectricity demand and pricing. This study extends the previous work by simultaneous consideration of climate change effects on high-elevation hydropower supply and pricing in California. The California's Energy-Based Hydropower Optimization Model (EBHOM 2.0) is applied to evaluate the adaptability of California's high-elevation hydropower system to climate warming, considering the warming effects on hydroelectricity supply and pricing. The model's results relative to energy generation, energy spills, reservoir energy storage, and average shadow prices of energy generation and storage capacity expansion are examined and discussed. These results are compared with previous studies to emphasize the need to consider climate change effects on hydroelectricity demand and pricing when exploring the effects of climate change on hydropower operations.

One of the most important environmental issues facing the hydropower industry is the adverse impact of hydroelectric projects on downstream fish passage. Fish that migrate long distances as part of their life cycle include not only important diadromous species (such as salmon, shads, and eels) but also strictly freshwater species. The hydropower reservoirs that downstream-moving fish encounter differ greatly from free-flowing rivers. Many of the environmental changes that occur in a reservoir (altered water temperature and transparency, decreased flow velocities, increased predation) can reduce survival. Upon reaching the dam, downstream-migrating fish may suffer increased mortality as they pass through the turbines, spillways and other bypasses, or turbulent tailraces. Downstream from the dam, insufficient environmental flow releases may slow downstream fish passage rates or decrease survival. There is a need to refine our understanding of the relative importance of causative factors that contribute to turbine passage mortality (e.g., strike, pressure changes, turbulence) so that turbine design efforts can focus on mitigating the most damaging components. Further, present knowledge of the effectiveness of turbine improvements is based on studies of only a few species (mainly salmon and American shad). These data may not be representative of turbine passage effects for the hundreds of other fish species that are susceptible to downstream passage at hydroelectric projects. For example, there are over 900 species of fish in the United States. In Brazil there are an estimated 3,000 freshwater fish species, of which 30% are believed to be migratory (Viana et al. 2011). Worldwide, there are some 14,000 freshwater fish species (Magurran 2009), of which significant numbers are susceptible to hydropower impacts. By comparison, in a compilation of fish entrainment and turbine survival studies from over 100 hydroelectric projects in the United States, Winchell et al. (2000

The Role of Anthropogenic Stratigraphy in River Restoration Projects
Evans, J. E.; Webb, L. D.
2012-12-01
As part of a river restoration project and removal of a low-head dam on the Ottawa River (northwestern Ohio and southeastern Michigan) in 2007, a longer-term project was initiated to assess anthropogenic changes of the Ottawa River fluvial system. A composite stratigraphic section 4.5 m in length was constructed by stratigraphic correlation from three trenches up to 2.5 m in depth and 14 vibracores up to 2.5 m in length, all within a small region (tires, intact or pieces of glass bottles, and one horizon of displaced railroad ties. Age control for the composite section is provided by 4 14C dates, 6 OSL dates, and one bottle with a date stamp. Two prominent flood horizons are indicated in multiple trenches or cores, and identified as the historic floods of 1913 and 1959. The data show the following major changes in the fluvial system over time: (1) prior to approximately 5 Ka, the river system was transporting mineral-rich sediment and formed meandering point-bar sequences approximately 1.5 m thick; (2) between approximately 5 Ka and 200 YBP, the river system was transporting organic-rich sediment (i.e., blackwater stream) bordered by riparian wetlands accumulating peat (part of the regional "Great Black Swamp" discovered by settlers from eastern North America); (3) between approximately 200 YBP and the early 1960s the river system was transporting mineral-rich sediment (i.e., brownwater stream), probably sourced from extensive land clearance for agriculture, which backfilled and overtopped the previous riparian wetlands and produced an series of thin channel fills interpreted as rapidly shifting avulsional channels; (4) since the early 1960s, sediment supply has exceeded sediment conveyance capacity, leading to vertical aggradation of approximately 1.7 m, creating the fill-terrace morphology evident today; and (5) overlapping with the previous stage, channel incision and lateral channel migration has produced a fluvial system dominated by bank erosion, logjams due

The Kootenai Tribe of Idaho, in cooperation with local, State, Federal, and Canadian agency co-managers and scientists, is assessing the feasibility of a Kootenai River habitat restoration project in Boundary County, Idaho. This project is oriented toward recovery of the endangered Kootenai River white sturgeon (Acipenser transmontanus) population, and simultaneously targets habitat-based recovery of other native river biota. Projects currently (2010) under consideration include modifying the channel and flood plain, installing in-stream structures, and creating wetlands to improve the physical and biological functions of the ecosystem. River restoration is a complex undertaking that requires a thorough understanding of the river. To assist in evaluating the feasibility of this endeavor, the U.S. Geological Survey collected and analyzed the physical and chemical nature of sediment cores collected at 24 locations in the river. Core depths ranged from 4.6 to 15.2 meters; 21 cores reached a depth of 15.2 meters. The sediment was screened for the presence of chemical constituents that could have harmful effects if released during restoration activities. The analysis shows that concentrations of harmful chemical constituents do not exceed guideline limits that were published by the U.S. Army Corps of Engineers in 2006.

On considering only the economical and radiological criteria, and on the base of available information and adopted hypothesis, the benefits expected from the building project of an embankment on the Pripyat river lead to just compensate the building and maintenance costs estimated for this project. Nevertheless, taking into account the expected positive effects on different sectors of economy, the project of an embankment of Chernobyl, initiated more than twelve years after the accident, will be, in a long term perspective, an efficient mean to improve the radiations situation and the life conditions for the Ukraine populations.
