Full Text Available The paper contributes to the exploration and understanding of the social geographies of public space in the Victoria & Alfred Waterfront (V&AW in Cape Town. The aim is to understand Capetonians’ (visitors and employees perceptions of the V&AW as public, leisure, shopping and working spaces. The appropriate literature on waterfront developments in providing public, working and leisure space is reviewed. Two questionnaire surveys (visitors and employees as well as eight unstructured interviews with important role players in the tourism industry of Cape Town were conducted. Findings revealed the most important reasons for Capetonians to visit or use certain spaces in the V&AW, the public open spaces they liked and how they perceived the V&AW as an inclusive space. The research also sought the respondents’ views on how the certain public spaces can be improved; what new activities and retail shops can be introduced; their opinions about the affordability of restaurants and parking; and how the V&AW can improve to cater for the needs of the Waterfront’s employees. Recommendations are made for making the V&AW more functional and accessible to Capetonians.

Plans have been developed for building two wind turbines on Toronto's waterfront, on the grounds of the exhibition for the project called Waterfront Windmill Project. The electricity generated by each individual turbine, 1,400,000 kilowatt hours per year, could meet the needs of 250 four-person homes. This project represents an emissions-free power generation, and the energy will be distributed to the hydropower grid of the City of Toronto. The requirement for nuclear and coal-generated energy will therefore be reduced while reducing the emissions of carbon dioxide and other greenhouse gases into the atmosphere. The creation of an urban-based community-owned turbine fits well with the policy of the Toronto Renewable Energy Coop, which is committed to working with the marketplace. The lower cost to the consumer of the market deregulation coal generated energy is a concern. figs

Full Text Available Water resources development at this time led to the front view policy known as waterfront term. This policy is to make water resources as the main area for regional development. The concept of ‘front view’ was developed originally to give understanding to people of the water resources as not only functional but also interesting to look at. On the other side, front view-based development has become the means of developing active interaction among people aroung the site. With regard to the construction of waterfront along the river, the social interaction of community members has become more meaningful, because apparently this is the cause of the unity of the community in the development of their area. As the most communities along the river are lower middle class people who are prone to conflict, this idea of front view-based river bank construction has united the people on one side of the river with another.

This work focuses on the analysis of the capability of Ground-Penetrating radar (GPR) technique for evaluating how the water penetrates into concrete samples by means of the assessment of the waterfront advance. Research activities have been carried out during a Short-Term Scientific Missions (STSMs) funded by the COST (European Cooperation in Science and Technology) Action TU1208 "Civil Engineering Applications of Ground Penetrating Radar" in November 2015. The evaluation of water penetrability is crucial in most building materials, such us concrete, since, water and aggressive chemical agents dissolved therein contribute to the deterioration of the material. A number of techniques have been developed to measure their advance in concrete. Although the most common method for measuring water content is the gravimetric method by observing the change in mass, this method has a large number of disadvantages. In this context, non-destructive techniques as GPR play an interesting role. In particular, the application of GPR in the building materials area is providing very promising and interesting results regarding the building materials characterization and especially concrete deterioration evaluation [1-3]. In addition, recent experimental studies highlight the strong relation between wave propagation parameters (velocity and energy level) and water content advance [4-5]. Water content has a decisive influence on dielectric properties and those might be assessed by the study of the wave properties that are derived by using GPR. Therefore, the waterfront advance will result in a change on wave parameters. In line with this, this research is focused on the development of specific processing algorithms necessary to understand how the water penetrates and how the wave parameters will be affected regarding the location of the antenna in reference to the water absorption direction. For this purpose, concrete samples were manufactured, which after curing (90 days) and oven

Urban waterfront rehabilitation: can it contribute to environmental improvements in the developing world?

Vollmer, Derek

2009-01-01

This paper examines urban waterfront rehabilitation as a sustainable development strategy in Chinese cities. Though waterfront rehabilitation is increasingly being employed in developed world cities, the environmental benefits are not always clear. Nonetheless, China, like other developing countries, has shown interest in this strategy, for improving its local water quality, upgrading environmental management, and improving quality of life for urban residents. As developing world cities struggle to break from the traditional model of 'pollute first, clean up later', it is critical that they employ strategies which minimize or remediate environmental impacts while still promoting economic development. This paper analyzes three such projects: the Qinhuai River Environmental Improvement Project in Nanjing, the Suzhou Creek Rehabilitation in Shanghai, and the Wuli Lake Rehabilitation in Wuxi. A critical analysis indicates that these projects have served numerous purposes which contribute to the cities' sustainable development. Though waterways may not be restored to pristine conditions, the incremental improvements appear to be a necessary catalyst for sustainable urban development.

Pacific Gateway: State Surveillance and Interdiction of Criminal Activity on Vancouver’s Waterfront

Chris Madsen

2018-03-01

Full Text Available Unionised work environments within large seaports attract transnational organised crime, and this presents a challenge for law enforcement agencies. If media stories are true, a motorcycle club called the Hells Angels has established a presence on Vancouver area waterfronts since coming to the province of British Columbia. Associations between longshore union locals, club members, and known contacts are implied and presented as evidence of participation in criminality. This paper revisits the perception that criminal activity is endemic in the Port of Vancouver because of a lack of policing, adequate resources, and indifference from port authorities, employer bodies, as well as union leadership. In an era of heightened concerns about public safety and national security, federal and provincial governments understand the importance of seaports, especially in Vancouver and up the Fraser River. These port facilities are important to international trade that flows through them as part of Asia-Pacific Gateway and Corridor initiatives. Therefore, targeted investments, close coordination amongst government departments and agencies, and engagement with waterfront stakeholders promote secure places hard for organised criminals to operate freely.

The Evolution of the Coastal Economy: The Role of Working Waterfronts in the Alabama Gulf Coast

Full Text Available This article describes the evolution of the coastal economy in Alabama and examines the driving forces of the sustainable economy in a historical context. The input-output model was applied to assess the direct and secondary effects of output and employment in the coastal region. Results suggest that state industries are heavily dependent on waterfront-related activities in this area, which have fueled much of their rapid development in the past few decades. Tourism, ship building and repairing and transportation are the three dominating sources contributing to the coastal economy. There are a few general problems of working waterfronts in the coastal Alabama area, but there are also some unique problems (e.g., Hurricane Katrina, Deepwater Horizon oil spill. Policies for future sustainable development are proposed.

Placement of Public Art. Two Examples from Lisbon’s Waterfront

Science.gov (United States)

Ochoa, Rita

2017-10-01

In our contemporary cities, some public spaces seem to have greater ability to host art interventions, like historical centers, urban sprawl areas, gardens and parks, new residential districts, among others. Also in port cities, its waterfronts constitute privileged spaces for the placement of public art. On Lisbon’s riverfront, we can see a relevant number of works and of monuments of strong symbolic nature. In turn, the placement of public art is a way to value the inherently symbolic nature of the waterfronts and to emphasize its monumentality. However, the criteria for the placement of public art on those spaces are not always clear. In some cases, there are some thematic correspondences between the works and the places, namely with the theme of the water, the Discoveries and others like that. Nevertheless, we cannot observe a profound spatial integration, or a design with the context. In some cases, the artistic elements are produced with a logic of isolated work of art and later they are acquired and placed in some public space. In other cases, we assist to an unusual situation: a work is conceived in a strict relation with a place, but then, without any evident justification, it is dislocated to a completely different context. Or simply it is removed, disappearing from the public space. Although it seems a strange situation, such kind of dislocations often occurs in Lisbon. On this framework, this research proposes a discussion about the processes of implementation of public art. We will analyze two cases of public art replacement:1) The monument Primeira Travessia Aérea do Atlântico Sul (First Aerial Crossing of the South Atlantic), by Laranjeira Santos and Rodrigues Fernandes, 1972; and 2) The public sculpture Ribeira das Naus, by Charters de Almeida, 1995. Both works were designed to very specific and important places on Lisbon’s waterfront and both were later replaced to other locations on the inner city, quite far from the river. This kind of �

City/Sea Searching for a New Connection. Regeneration Proposal for Naples Waterfront Like an Harbourscape: Comparing Three Case Studies

Full Text Available The port is a strategic area of transition, where it is possible to perceive the territory-landscape and the urban front. However it lost its urban character, gradually becoming an high specialized independent machines, a sectorial infrastructure divided from the city: this phenomenon has created increasingly socio-economical marginalization.  Within a double view, lengthwise and transverse, we can describe the port as a space closed to the city and as an unfathomable barrier for the transverse flows that previously connected the waterfront to the city. The paper examines the case study of Naples, where the port expansion continues to grow without any integration with other parts of the city, distorting its “urban area” role, establishing its independence and making urban system compatibility conditions even weaker. The functional and physical division increases the perception of the port as a barrier rather than a filter. Turning the sense of these conditions aims at rethinking waterfront as a public space, a place where integration and specialization spaces become new open and accessible spatial devices. In some contemporary European and American cities (Aalborg, Oslo and Toronto we could see the port as multifunctional system, an interdisciplinary project that creates urban spaces integrated to the city and that allows the coexistence of different uses. The project of a new public space between the sea and the hinterland could involve all these conflicting functions creating, with different strategies, a potential multifunctional landscape. In Naples as well, where the waterfront is still waiting to be re-connected with the story of the city itself.

A Design competition as regeneration opportunity: the Fregene’s waterfront

Full Text Available The article aims to present a reflection on  the ability which has a local government to be able to regenerate a part of the city through a design competition. To do this we take as a case study of Fregene (formerly elected as a case study during a research on the development of new urban coastal centers, for which it was organized in 2006  a design competition with object the redevelopment of the waterfront. What it was considered important to carry out in this study is an attempt to update the new instances of urban regeneration that occurred: in fact, due to the recent urban transformations and the pressing economic crisis (combined with reduced physical of  a large part of  the beach the framework to meet the needs of today is more complex.Therefore, we addressed to a study of the state of the town, arriving at the objectives related to the transformation hypothesis, desirable, starting from the promenade, center for the function  and important for the relationship that allows us to establish the natural character of the coastal environment. We did, therefore, a comparison between the objectives spelled out in the notice of the administration in 2006 and those that currently appear focal for an integrated development of Fregene, to try to understand how we could rework the announcement today, in the light of the new order came to take shape.The rethinking of the waterfront, in addition to being the topic still actual, could be integrated with new instances identified, useful to a designer who is faced with the complexity of the topic. In addition, the reflection wants to focus on how the instrument of competition may be useful to carry out a survey of the possible hypotheses of transformation, and how it can be supported by other procedural elements, needed to achieve  the objectives of  urban  regeneration.

Full Text Available Culturalism and ethnicity form integral parts of destination attractions in tourism and hospitality. The article explores the degree of African authenticity expected by international travelers from a dining experiences in restaurants located in a popular tourist hub, the Victoria and Alfred Waterfront in Cape Town. The research reveals that integrating traditional African values and standards to five star dining international standards is difficult and problematic. Consequently international diners seeking authentic African dining experience in popular tourists’ hubs have been disappointed. The paper revealed that the majority 75.3% perceived the dining experience in the V&A Waterfront as just a copy of the Western countries, 19, 2% percent noted some African traits largely diluted by foreign standards and 6, 5% believed it was truly an African dining experience. The article recommends that, for commercial purposes a staged African experience be created using such strategies as manipulating the architecture, the music, interior décor, staff uniforms and anything that immediately identifies with Africa or South Africa on a more local level.

Culturable bioaerosols along an urban waterfront are primarily associated with coarse particles

Full Text Available The source, characteristics and transport of viable microbial aerosols in urban centers are topics of significant environmental and public health concern. Recent studies have identified adjacent waterways, and especially polluted waterways, as an important source of microbial aerosols to urban air. The size of these aerosols influences how far they travel, their resistance to environmental stress, and their inhalation potential. In this study, we utilize a cascade impactor and aerosol particle monitor to characterize the size distribution of particles and culturable bacterial and fungal aerosols along the waterfront of a New York City embayment. We seek to address the potential contribution of bacterial aerosols from local sources and to determine how their number, size distribution, and taxonomic identity are affected by wind speed and wind direction (onshore vs. offshore. Total culturable microbial counts were higher under offshore winds (average of 778 CFU/m3 ± 67, with bacteria comprising the majority of colonies (58.5%, as compared to onshore winds (580 CFU/m3 ± 110 where fungi were dominant (87.7%. The majority of cultured bacteria and fungi sampled during both offshore winds (88% and onshore winds (72% were associated with coarse aerosols (>2.1 µm, indicative of production from local sources. There was a significant correlation (p < 0.05 of wind speed with both total and coarse culturable microbial aerosol concentrations. Taxonomic analysis, based on DNA sequencing, showed that Actinobacteria was the dominant phylum among aerosol isolates. In particular, Streptomyces and Bacillus, both spore forming genera that are often soil-associated, were abundant under both offshore and onshore wind conditions. Comparisons of bacterial communities present in the bioaerosol sequence libraries revealed that particle size played an important role in microbial aerosol taxonomy. Onshore and offshore coarse libraries were found to be most similar

Rio de Janeiro's Waterfront: Urbanism and social representation of reality

Nara Iwata

2002-09-01

Full Text Available Post-modernity and economic globalization is inciting the competition among countries, regions and cities, in search of investments, consumers and resources. To pursue a new position in this global market, cities use new urban practices to re-discover and re-invent their identities and traditions, taken as attributes to attract consumers. In the city of Rio de Janeiro, the mythical dimension of the South Zone is inseparable and incorporated to its identity. In evaluating the history of Rio de Janeiro’s seaside, the social construction of its imagery and the projects that redesigned its urban signs, we can identify an intermittence of urban interventions, marked by the lack of a continuous management of the waterfront. We verify that, even though tourist marketing appraises the seaside as the main image of the city, it does not receive proportional attention from urban interventions, may be in account of not being understood as a social construction. We conclude that the importance of caring for the seaside must not be understood only as an esthetical question, but also as the valorization of Rio de Janeiro’s image, its inhabitants’ self-esteem and citizenship itself.

Principles of Waterfront Renovation to Decisive Spaces for Local Identity: A Study Case of Port Adelaide, South Australia

Taher, S.; Haqi, F. I.

2017-07-01

If governments have an objective to participate in a globalized economy, they should address the challenges of blighted inner city and particularly older water front areas. In doing the latter there is often a degree of consistency in place making. While the processes and principles behind urban design and planning need to have an internal logic across different scales to create quality public realms, the outcome of these interventions are frequently unresponsive to regional diversities in culture and identity. This indifference can lead to changes in the built form through urban regeneration activities that do not respect, celebrate or represent the history and traditions of the local community associated with an inner harbour or other forms of urban waterfronts. This research was undertaken to develop a set of design principles for the Inner Harbour renewal project in Port Adelaide, South Australia that would be sensitive to the historical role of the water front and in particular to incorporate the sentiments and needs of long term residents for whom the character of the area and their attachment to it shapes their sense of identity. The research established a theoretical framework for the development of design principles such as functionality, accessibility, natural environment and culture, history and memory. The findings showed that the redevelopment did not significantly disrupt residents’ sense of place or sense of local identity however some more additional design attributes would nevertheless strengthen the capacity of the project to preserve local identity. This paper concludes with recommendations for preserving local identity for residents adjacent to waterfront renewal projects.

Urban Blue Space and “The Project of the Century”: Doing Justice on the Seattle Waterfront and for Local Residents

Directory of Open Access Journals (Sweden)

Anne Taufen Wessells

2014-10-01

Full Text Available Urban blue space is increasingly embraced by cities as a specific and valuable genre of public space, valued for its economic, symbolic and experiential place attributes and essential to sustainable urban development. This article takes up the concept of urban blue space from a design perspective, extending and exploring it through a critical social science lens. Using the reconfiguration and redesign of the central Seattle waterfront as a case example, the idea of “doing justice” is enlisted to examine not just the design opportunities and formal characteristics of the site, but also the patterns of privilege, access and regional socio-ecological equity that are raised through its redesign. After situating the extraordinary design opportunity presented by this iconic urban blue space, and the imperative to do justice to the waterfront’s physical situation, the article presents the site from four additional and discrete perspectives: economic justice, environmental justice, social justice and tribal justice. By thus foregrounding the urban political ecology of the waterfront, the article demonstrates that the most important challenge of the site’s redevelopment is not technological, financial or administrative, although these are real, and significant challenges, but rather, the need to construct a place that works to counter established patterns of local and regional injustice. In Seattle as in other coastal port cities, urban blue space is a shared public and environmental good, with unique and demanding governance responsibilities for its conceptualization and sustainable development.

Onshore Wind Speed Modulates Microbial Aerosols along an Urban Waterfront

Full Text Available Wind blowing over aquatic and terrestrial surfaces produces aerosols, which include microbial aerosols. We studied the effect of onshore wind speeds on aerosol concentrations as well as total and culturable microbial aerosols (bacterial and viral at an urban waterfront (New York, NY, United States of America. We used two distinct methods to characterize microbial aerosol responses to wind speed: A culture-based exposure-plate method measuring viable bacterial deposition near-shore (CFU accumulation rate; and a culture-independent aerosol sampler-based method measuring total bacterial and viral aerosols (cells m−3 air. While ambient coarse (>2 µm and fine (0.3–2 µm aerosol particle number concentrations (regulated indicators of air quality decreased with increasing onshore wind speeds, total and depositing culturable bacterial aerosols and total viral aerosols increased. Taxonomic identification of the 16S rDNA of bacterial aerosol isolates suggested both terrestrial and aquatic sources. Wind appears to increase microbial aerosol number concentrations in the near-shore environment by onshore transport at low wind speeds (<4 m s−1, and increased local production and transport of new microbial aerosols from adjacent water surfaces at higher wind speeds (>4 m s−1. This study demonstrates a wind-modulated microbial connection between water and air in the coastal urban environment, with implications for public health management and urban microbial ecology.

Leus, M.; Winkels, P.; Hannes, E.

2018-04-01

In Kunduchi, located in the Kinondoni district of the Dar es Salaam Region, it is of vital importance for the lives and livelihoods of the indigenous people to preserve the typical ecosystems and ensure the identity and economic resilience of these areas. The problem statement is as follows: In what way can sustainable tourism in Kunduchi serve as an engine for economic and social empowerment? How can Kunduchi be an inspiring example for the development of the coast of Dar Es Salaam in Tanzania that is threatened by large-scale tourist infrastructure? How to design sustainable solutions with respect for the local community and the local traditions? Firstly, a theoretical framework that connects sustainable tourism with the sustainable development of coastal areas is defined. Assumptions made on the basis of the literature review provide parameters that play an important role in the architectural concepts. Secondly, a research by design is presented in order to analyze and evaluate different scenarios to outline the opportunities of sustainable tourism on site of Kunduchi. Sustainable waterfront development is an obvious subtitle since the subtle spatial integration of these projects in the urban and water related context of Dares Salaam is of major importance.

A View From The Sea The Regeneration of Marseille Waterfront: Iconic Buildings And Mediterranean Sea

Maria Elena Buslacchi

2014-01-01

Full Text Available In this paper I will discuss how the isomorphic trend of urban regeneration of waterfronts implies a modeling which is not free from critical points. If we focus on the growing use of art and culture as a tool, both in stable museum form both in ephemeral festival form, we must pair this tool with a local contextualization which requires a deep and multi-prospectic knowledge of the territory. In this context a view “from the sea” becomes fundamental when we think to renovate the identity of the port cities materially and, at the same time, symbolically. First a general introduction about the actual evolution of strategies for regeneration of coastal areas will be given. Then two fundamental specific case-studies in the regeneration of the city of Marseille  will be discussed: Vieux Port and the Esplanade - Fort St-Jean. These areas, studied during my Ph. D. thesis, are meaningful for the connection generated between the local reality and the original project, based on a general purpose model. This paper will try to employ ethnographic methodology to examine which functions have been associated to renewed areas and how these acquired functions can be connected with project steps and with already observed results in other cities. A descriptive approach is predominant in this work; anyway a critical judgment cannot be avoided. This sort of judgment is not to be extended to all the other effects which cannot be directly observed within the case-study.

Conde, Daniel; Telhado, Maria J.; Viana Baptista, Maria A.; Antunes, Carlos M.; Ferreira, Rui M. L.

2014-05-01

The Tagus estuary is recognized as an exposed location to tsunami occurrences, given its proximity to tsunamigenic faults such as the Marquês de Pombal and the Horseshoe fault system. Lisbon, bordered by the Tagus estuary, is a critical point of Portugal's tsunami hazard map, having been affected by several tsunamis (Baptista and Miranda, 2009) including the notorious event of November 1st 1755, the last major natural disaster known to have inflicted massive destruction in Portugal. The main objective of this work, a joint initiative of CEHIDRO (IST - Universidade de Lisboa) and the Municipal Civil Protection Services of Lisbon, is to contribute to the quantification of severity and exposure of Lisbon waterfront to tsunami events. For that purpose, the propagation of a tsunami similar to that of the 1st November of 1755 in the Tagus estuary was numerically simulated. Several scenarios were considered, articulating the influence of tidal (low and high tides), atmospheric (increase in water level due to storm surges) and hydrological (flow discharge in Tagus river) conditions. Different initial and boundary conditions were defined for each modelling scenario but the magnitude of the tsunami remained what is believed to be an exceptional event. The extent of the inundation and relevant hydrodynamic quantities were registered for all scenarios. The employed simulation tool - STAV-2D - was developed at CEHIDRO (IST) and is based on a 2DH spatial (Eulerian) shallow-flow approach suited to complex and dynamic bottom boundaries. The discretization technique relies on a finite-volume scheme, based on a flux-splitting technique incorporating a reviewed version of the Roe Riemann solver (Canelas et al. 2013, Conde et al. 2013). STAV-2D features conservation equations for the finer solid phase of the flow and also a Lagrangian model for the advection of larger debris elements. The urban meshwork was thoroughly discretized with a mesh finer than average street width. This fine

Acoustic, Visual and Spatial Indicators for the Description of the Soundscape of Waterfront Areas with and without Road Traffic Flow

Full Text Available High flows of road traffic noise in urban agglomerations can negatively affect the livability of squares and parks located at the neighborhood, district and city levels, therefore pushing anyone who wants to enjoy calmer, quieter areas to move to non-urban parks. Due to the distances between these areas, it is not possible to go as regularly as would be necessary to satisfy any needs. Even if cities are densely populated, the presence of a sea or riverfront offers the possibility of large restorative places, or at least with potential features for being the natural core of an urban nucleus after a renewal intervention. This study evaluates the soundscape of the Naples waterfront, presenting an overview of the most significant visual, acoustic and spatial factors related to the pedestrian areas, as well as areas open to road traffic and others where the road traffic is limited. The factors were chosen with feature selection methods and artificial neural networks. The results show how certain factors, such as the perimeter between the water and promenade, the visibility of the sea or the density of green areas, can affect the perception of the soundscape quality in the areas with road traffic. In the pedestrian areas, acoustic factors, such as loudness or the A-weighted sound level exceeded for 10% of the measurement duration (LA10, influence the perceived quality of the soundscape.

Contests over social memory in waterfront Vancouver: Historical editing & obfuscation through public art

Directory of Open Access Journals (Sweden)

Gordon Brent Ingram

2000-02-01

Full Text Available Every public art site has a relationship to the history of surrounding areas whether in obscuring social memory or in highlighting certain relationships and events over others. Over the last decade, much of central Vancouver's waterfront, particularly around False Creek (a marine inlet, has been redeveloped with international capital - much of which has been linked to Hong Kong. Several large redevelopment areas have involved close cooperation in urban design processes between `the city' and `the developer'. In these megaprojects, public art has emerged as a more substantial and stable urban amenity while becoming less overtly ideological and associated with democratic public space. In this part of North America, such relatively public art projects have become almost iconographic for economic and social changes associated with globalization. Contentious historical information has tended to be censored - particularly around a range of non-European communities and events over the last century involving social conflict. In the same period, outdoor art has been increasingly used as a part of strategies to reclaim public space and attempts to democratize it. These two kinds and functions of public art have tended to be used for divergent experiences of the relationships of history to the present, of public space and the existence of and responses to social conflict, and of `sense of place'. Six public art sites, with four built, along the north shore of False Creek, in central Vancouver, are analyzed in terms of their cultural, urban and spatial politics and, in particular, in terms of contemporary tensions around the extent of aboriginal presence before and after the arrival of Europeans, the multiracial and multicultural origins and character of the city, contamination with toxic chemicals, violence against women, and the AIDS pandemic. A method for better analyzing the cultural politics of public art sites (and the design processes that were

Converging social classes through humanized urban edges

Abuan, M. V.; Galingan, Z. D.

2017-10-01

Urban open spaces are created to be used by people. It is a place of convergence and social activity. However, these places have transformed into places of divergence. When spaces become dehumanized, it separates social classes. As a result, underused spaces contribute to urban decay. Particularly an urban edge, the JP Rizal Makati Waterfront Area is the center of this paper. The JP Rizal Makati Waterfront Area is a waterfront development situated along the banks of one of Metro Manila’s major water thoroughfare --- Pasig River. The park and its physical form, urban design and landscape tend to deteriorate over time --- creating a further division of social convergence. Social hostility, crime, negligent maintenance and poor urban design are contributing factors to this sprawling decay in what used to be spaces of bringing people together. Amidst attempts to beautify and renew this portion of Makati City’s edge, the urban area still remains misspent.This paper attempts to re-humanize the waterfront development. It uses the responsive environment design principles to be able to achieve this goal.

Development of Urban Inundation Warning Model at Cyclic Artificial Water Way in Song-do International City, Republic of Korea

Science.gov (United States)

Lee, T.; Lee, C.; Kim, H.

2016-12-01

Abstract Song-do international city was constructed by reclaiming land from the coastal waters of Yeonsu-gu, Incheon Metropolitan City, Republic of Korea. The □-shaped cyclic artificial water way has been considered for improving water quality, waterfront and internal drainage in Song-do international city. By improving water quality, various marine facilities, such as marina, artificial beach, marine terminal, and so on, will be set up around the artificial water way for the waterfront. Since the water stage of the artificial water way changes depending on water gates operations, it is necessary to develop an urban inundation warning model to evaluate safeties of the waterfront facilities and its passengers. By considering characteristics of urban watershed, we calculate discharge flowing into the water way using XP-SWMM model. As a result of estimating 100-year flood frequency, although there are slight differences in drainage sections, the maximum flood discharge occurs in 90-min rainfall duration. In order to consider impacts of tide and hydraulic structure, we establish Inland drainage plans through the analysis of unsteady flow using HEC-RAS. The urban inundation warning model is configured to issue a warning when the water plain elevation exceeds EL. 1.5m which is usually managed at EL. 1.0m. In this study, the design flood stage of artificial water way and urban inundation warning model are developed for Song-do international city, and therefore it is expected that a reliability of management and operation of the waterfront facilities is improved. Keywords : Artificial Water Way; Waterfront; Urban Inundation Warning Model. Acknowlegement This research was supported by a grant [MPSS-NH-2015-79] through the Disaster and Safety Management Institute funded by Ministry of Public Safety and Security of Korean government.

Full Text Available The global transport systems were much improved from the endof the 1960s, through density and network development. In thecontemporary post-Fordist production system the productionfragmentation and the strict following of the just in time principle led to the rapid growth of transports at international level.

With this change, the urban waterfront no longer realize the interface with the port-city in a direct way, but in a symbolic one.

Book Review: Radiation protection and measurement issues related to cargo scanning with accelerator-produced high-energy X rays, NCRP Commentary No. 20

International Nuclear Information System (INIS)

May, Robert

2008-01-01

Having spent roughly the first third of his health physics career on the Norfolk, VA waterfront area, the reviewer was excited to see the NCRP Commentary 20, 'Radiation Protection and Measurements Issues Related to Cargo Scanning with Accelerator Technology'. It signals the advent of the Cargo Advanced Automated Radiography System (CAARS). The waterfront is a border that challenges physical security programs and technology. As Commentary 20 provides in the introduction, waterfront cargo terminals and land border crossings together represent over 300 ports of entry in the USA. Every year, the USA receives over 10 million cargo containers from commercial shipping and a roughly equal amount from land border crossings. While rapidly processing containerized cargo, CAARS will be able to detect small quantities of high atomic number radioactive materials and dense shielding materials used for radioactive gamma ray sources and even illicit human cargo - important concerns for homeland security. It will also be able to detect other contraband such as explosives, weapons and drugs. Section 1 of the Commentary presents an executive summary with NCRP's radiation dose management recommendations and related operational recommendations for effective implementation of CAARS technology in the current regulatory environment.

Zhang Yuanhang; Yang Chunlin; Wen Shenglin; Shi Qikai; Wang Jian

2013-01-01

In inertial confinement fusion (ICF) research process, the form of focal spot is extremely crucial. Especially in the indirect driven implosion, energy circled fraction is higher than 95% in focal spot. Based on the offline test platform, the focusing spot of continuous phase plates with different application error is clearly imaged on CCD. By experimental analysis, it is found that the beam rotation error, caliber error, translational error and inclination error have a high tolerance in affecting focal plane of CPP. Energy circled fraction is higher than 95%, the range is less than 0.5%. Nevertheless, the waterfront aberration seriously affects the shaping ability of the CPP. Clearly, the main factor of reducing energy circled fraction to less than 90% is waterfront aberration. (authors)

Island Megalopolises: Tunnel Systems as a Critical Alternative in Solving Transport Problems

Directory of Open Access Journals (Sweden)

Vladimir V. Makarov

2018-02-01

Full Text Available A principal difficulty with island megalopolises is the transport problem, which results from limited surface land on an already developed island, on which roads and car parking can be placed. This limitation leads to traffic jams on the small number of roads and to intrusive car parking in any available surface location, resulting in safety issues. The city of Vladivostok is located on the Muravyov-Amursky Peninsula in the Russia Far East region (the Primorsky Krai. This city is essentially the third capital of Russia because of its important geopolitical location. To address the car traffic problems in Vladivostok, and because of the absence of places to build new roads, the city administration has proposed the usage of the beaches and waterfronts along the sea coast in this regard. This decision is in sharp conflict with Vladivostok’s ecological and social aspirations to be recognized as a world-class city. It also neglects the lessons that have been learned in many other waterfront cities around the world, as such cities have first built aboveground waterfront highways and later decided to remove them at great expense, in order to allow their citizens to properly enjoy the environmental and historical assets of their waterfronts. A key alternative would be to create an independent tunneled transport system along with added underground parking so that the transport problems can be addressed in a manner that enhances the ecology and livability of the city. A comparison of the two alternatives for solving the transport problem, that is, underground versus aboveground, shows the significant advantages of the independent tunnel system. Complex efficiency criteria have been developed in order to quantify the estimation of the alternative variants of the Vladivostok transport system. It was determined that the underground project is almost 1.8 times more advantageous than the aboveground alternative. Keywords: Megalopolises, Transport, Tunnels

A partir de cuatro casos seleccionados (Baltimore, Sidney, Barcelona y Buenos Aires, el artículo subraya la estandarización del diseño y de los programas ejecutados en importantes renovaciones de waterfronts. Se propone una analogía con la cadena norteamericana de café Starbucks, con la cadena de restoranes de fast food McDonald’s y con los parques de entretención Disney. De escalas diferentes, los emprendimientos mencionados se caracterizan por presentarse desligados de los lugares físicos donde se localizan y por construir una nueva experiencia. Se sostiene que en la mayoría de los casos escogidos, el frente de agua renovado es ajeno a su medio y parece tener más que ver con un centro comercial que con un nuevo espacio público en la ciudad. Sin embargo, con el tiempo, gran parte de los ejemplos han fundado una nueva categoría de espacio público, se han convertido en hitos dentro de las ciudades y responden a la necesidad del ciudadano de tener nuevos lugares de recreación y encuentroCountless cities throughout the world have renewed their old port areas turning them into new waterfronts.

Full Text Available The Revitalization of Badung River has provided a significant waterfront for Denpasar. Havingbeen used for irresponsibly disposed waste, this river has now emerged as a significant publicspace. It has promoted diverse recreational activities engaged by urban dwellers of both Denpasarand its surrounding areas. This paper analyses the relationship between numerous spatial settingsalong the river and their contained recreational activities. The potential attraction of each spatialsetting is evaluated by the presence of one or more of the following elements, visible sceneries;aesthetic plants; shade trees; fish; planned space; abandoned or/and vacant land. Meanwhile, typeof activities pertained to recreational function of this waterfront include relaxing; sitting around;fishing; chatting; snacking; resting after work; ceremonial activities; and food vendoring(permanent and non-permanent. The research then makes a connection between each spatialelement and activities to draw certain relationships between space and its use.

Alternative energy facility siting policies for urban coastal areas: executive summary of findings and policy recommendations

Energy Technology Data Exchange (ETDEWEB)

Morell, D; Singer, G

1980-11-01

An analysis was made of siting issues in the coastal zone, one of the nation's most critical natural resource areas and one which is often the target for energy development proposals. The analysis addressed the changing perceptions of citizens toward energy development in the coastal zone, emphasizing urban communities where access to the waterfront and revitalization of waterfront property are of interest to the citizen. The findings of this analysis are based on an examination of energy development along New Jersey's urban waterfront and along the Texas-Louisiana Gulf Coast, and on redevelopment efforts in Seattle, San Francisco, Boston, and elsewhere. The case studies demonstrate the significance of local attitudes and regional cooperation in the siting process. In highly urbanized areas, air quality has become a predominant concern among citizen groups and an influential factor in development of alternative energy facility siting strategies, such as consideration of inland siting connected by pipeline to a smaller coastal facility. The study addresses the economic impact of the permitting process on the desirability of energy facility investments, and the possible effects of the location selected for the facility on the permitting process and investment economics. The economic analysis demonstrates the importance of viewing energy facility investments in a broad perspective that includes the positive or negative impacts of various alternative siting patterns on the permitting process. Conclusions drawn from the studies regarding Federal, state, local, and corporate politics; regulatory, permitting, licensing, environmental assessment, and site selection are summarized. (MCW)

Metrics of Urban Sustainability: A Case Study of Changing Downtowns in Thunder Bay, Canada

Directory of Open Access Journals (Sweden)

Todd Randall

2017-07-01

Full Text Available Thunder Bay, a medium-sized city in Northern Ontario, has a twin downtown core model, arising from the merging of two former cities in 1970. Its north core, designated as the City’s Entertainment District has received considerable investment, notably a major waterfront renewal project undertaken in 2009 as part of an overall strategy towards downtown revitalization. Greater diversity of commercial functions and increasing residential capacity in downtowns are considered positive steps towards sustainable urban development. It is hoped the leadership taken by the City in its downtown capital investments can stimulate others (corporations and individuals to re-invest in both living and working in more central locations to the benefit of environmental sustainability indicators like journey-to-work (distance and mode selected and residential density. This article tracks changes in business composition and residential capacity during a five year period via the development of an intensive database of business and institutional activities. Urban sustainability metrics developed include residential capacity and density, business vacancy rates and business composition and turnover, which complement an existing measure of land-use diversity developed in earlier research. While major capital investments in downtown revitalization (such as the waterfront project have fairly long-term impact horizons, data suggest some positive trends in the developed metrics in the downtown north core since 2009. In particular, there have been notable investments in waterfront condos and downtown lofts and some diversification in the food retailing and restaurant sectors. However, overall trends in downtown commerce are currently flat, indicative of a struggling local economy and a continued suburbanization of key commercial sectors.

“Economic heritage impact assessment” come strumento per valutare gli impatti dei grandi progetti di riqualificazione delle città costiere siti Unesco. Il caso studio di Torre Annunziata nel golfo di Napoli

Directory of Open Access Journals (Sweden)

Mariarosaria Angrisano

2015-12-01

Full Text Available Quest’articolo parte dallo studio delle città portuali storiche, siti UNESCO, che oggi affrontano la sfida della riqualificazione dei waterfront urbani attraverso la conservazione del patrimonio culturale e paesaggistico. Le raccomandazioni sull’ “Historic Urban Landscape”, e gli strumenti operativi promossi dall’ICOMOS “Guidance on Heritage Impact Assessments for Cultural World Heritage Properties” del 2011, si configurano come le più recenti disposizioni concernenti la conservazione, protezione e valorizzazione del patrimonio culturale (Fusco Girard, 2010. La Guida ICOMOS è stata considerata lo strumento più adatto per valutare gli impatti dei grandi progetti di riqualificazione dei waterfront urbani sul patrimonio culturale. Per comprendere al meglio tale strumento è stata fatta un’applicazione per valutare gli impatti del Grande Progetto Pompei sul waterfront di Torre Annunziata, città costiera nel Golfo di Napoli sito UNESCO. A questa fase di analisi segue una riflessione su come migliorare l’Heritage Impact Assessment, come strumento capace di valutare non soltanto gli impatti culturali ma anche quelli economici, per parlare di “economia del patrimonio culturale”. La proposta ultima è quella di affiancare al processo di “Heritage Impact Assessment” una valutazione degli impatti economici, attraverso un’analisi costi-benefici, per quantificare in termini monetari la convenienza degli investimenti nella conservazione del patrimonio storico urbano delle città costiere, proponendo una “Economic Heritage Impact Assessment” (EHIA. Tale metodo, elaborato dall’autrice all’interno della tesi di dottorato “Il paesaggio storico urbano delle città costiere: sfide e opportunità. Il caso Torre Annunziata”, offre la possibilità di superare la sola valutazione degli impatti culturali proposta dall’ICOMOS.

2011-08-01

Personal exposures and ambient concentrations of air toxics were characterized in a pollution "hot spot" and an urban reference site, both in Camden, New Jersey. The hot spot was the city's Waterfront South neighborhood; the reference site was a neighborhood, about 1 km to the east, around the intersection of Copewood and Davis streets. Using personal exposure measurements, residential ambient air measurements, statistical analyses, and exposure modeling, we examined the impact of local industrial and mobile pollution sources, particularly diesel trucks, on personal exposures and ambient concentrations in the two neighborhoods. Presented in the report are details of our study design, sample and data collection methods, data- and model-analysis approaches, and results and key findings of the study. In summary, 107 participants were recruited from nonsmoking households, including 54 from Waterfront South and 53 from the Copewood-Davis area. Personal air samples were collected for 24 hr and measured for 32 target compounds--11 volatile organic compounds (VOCs*), four aldehydes, 16 polycyclic aromatic hydrocarbons (PAHs), and particulate matter (PM) with an aerodynamic diameter 0.6) was found between benzene and MTBE in both locations. These results suggest that automobile exhausts were the main contributors to benzene and MTBE air pollution in both neighborhoods. Formaldehyde and acetaldehyde concentrations were found to be high in both neighborhoods. Mean (+/- SD) concentrations of formaldehyde were 20.2 +/- 19.5 microg/m3 in Waterfront South and 24.8 +/- 20.8 microg/m3 in Copewood-Davis. A similar trend was observed for the two compounds during the saturation-sampling campaigns. The results indicate that mobile sources (i.e., diesel trucks) had a large impact on formaldehyde and acetaldehyde concentrations in both neighborhoods and that both are aldehyde hot spots. The study also showed that PM2.5, aldehydes, BTEX, and MTBE concentrations in both Waterfront South

An Examination of an Iconic Trap-Neuter-Return Program: The Newburyport, Massachusetts Case Study

Directory of Open Access Journals (Sweden)

Daniel D. Spehar

2017-10-01

Full Text Available The use of trap-neuter-return (TNR as a humane alternative to the lethal management of free-roaming cats has been on the rise for several decades in the United States; however a relative paucity of data from TNR programs exists. An iconic community-wide TNR effort; initiated in 1992 and renowned for having eliminated hundreds of free-roaming cats from the Newburyport; Massachusetts waterfront; is cited repeatedly; yet few details appear in the literature. Although the presence of feline population data was quite limited; a detailed narrative emerged from an examination of contemporaneous reports; extant TNR program documents; and stakeholder testimony. Available evidence indicates that an estimated 300 free-roaming cats were essentially unmanaged prior to the commencement of the TNR program; a quick reduction of up to one-third of the cats on the waterfront was attributed to the adoption of sociable cats and kittens; the elimination of the remaining population; over a 17-year period; was ascribed to attrition. These findings illuminate the potential effectiveness of TNR as a management practice; as well as call attention to the need for broad adoption of systematic data collection and assessment protocols.

Difficult balances and impossible partners. The implementation local plan for San Giovanni a Teduccio in Naples.

Directory of Open Access Journals (Sweden)

Enrico Formato

2014-02-01

Full Text Available This article is about the processes involved in preparing the preliminary draft of the implementation local plan (ILP of the San Giovanni a Teduccio district of Naples (2008. The plan, drawn up during the activities of the Innovative programme in the urban field (PIAU financed by the Ministry of Infrastructure in 2004, aims to integrate a series of initiatives, already in progress or planned in the district for the designing of public space, by giving special attention to the redevelopment of the waterfront and the strengthening of its relationships with the city. In the given conditions, the solutions proposed by the plan represent the most advanced point of balance between different visions which general urban planning and subsequent programme agreements can bring about. Finally, ILP’s work is subjected to a persistent contradiction, a structural incompatibility between the activities of the commercial port and the renovation of the waterfront: port and city generate a dialectic which, at present, is not conducive either to economic development based on the logistics or to urban renovation. Why don’t we look for other options rather than this unfruitful incompatibility?

Real-estate lakes

Rickert, David A.; Spieker, Andrew Maute

1971-01-01

Since the dawn of civilization waterfront land has been an irresistible attraction to man. Throughout history he has sought out locations fronting on oceans, rivers, and lakes. Originally sought for proximity .to water supply and transportation, such locations are now sought more for their esthetic qualities and for recreation. Usable natural waterfront property is limited, however, and the more desirable sites in many of our urban areas have already been taken. The lack of available waterfront sites has led to the creation of many artificial bodies of water. The rapid suburbanization that has characterized urban growth in America since the end of World War II, together with increasing affluence and le-isure time, has created a ready market for waterfront property. Accordingly, lake-centered subdivisions and developments dot the suburban landscape in many of our major urban areas. Literally thousands of lakes surrounded by homes have materialized during this period of rapid growth. Recently, several "new town" communities have been planned around this lake-centered concept. A lake can be either an asset or a liaoility to a community. A clean, clear, attractively landscaped lake is a definite asset, whereas a weed-choked, foul-smelling mudhole is a distinct liability. The urban environment poses both problems and imaginative opportunities in the development of lakes. Creation of a lake causes changes in all aspects of the environment. Hydrologic systems and ecological patterns are usually most severely altered. The developer should be aware of the potential changes; it is not sufficient merely to build a dam across a stream or to dig a hole in the ground. Development of Gl a successful lake requires careful planning for site selection and design, followed by thorough and cc ntinual management. The purpose of this report is to describe the characteristics of real-estate lakes, to pinpoint potential pmblems, and to suggest possible planning and management guidelines

The Canterbury earthquakes of 2011 caused widespread damage in the historic Lyttelton town centre. One of the many casualties was the former Lyttelton post office building. Constructed in 1875, the building as well as the parcel of land on which it was constructed was deemed archaeological and an emergency archaeological authority was obtained by the Canterbury Earthquake Recovery Agency prior to the building and its foundations being removed. During the removal of the foundations in August 2011 archaeological deposits associated with pre-contact Maori occupation were encountered. (author)

Prime waterfront real estate: Apple snails choose wild taro for oviposition sites

Directory of Open Access Journals (Sweden)

Colin H. KYLE, Alexis W. KROPF, Romi L. BURKS

2011-10-01

Full Text Available While difficult to prevent introductions, scientific research can help guide control efforts of exotic, invasive species. South American island apple snails Pomacea insularum have quickly spread across the United States Gulf Coast and few control measures exist to delay their spread. Usually occupying cryptic benthic habitats, female apple snails crawl out of the water to deposit large, bright pink egg clutches on emergent objects. To help identify the most likely place to find and remove clutches, we conducted four lab experiments to investigate what specific object qualities (i.e. material; shape and height; plant species; natural and artificial attracted P. insularum females to lay clutches. In our fourth experiment, we specifically examined the relationship between female size and reproductive output. To further understand reproductive output, we quantified experimental clutch chara- cteristics (height above water, dimensions, mass, approximate volume, number of eggs, hatching efficiency. Pomacea insularum females laid more clutches on plant material, chose round over flat surfaces and failed to differentiate between tall and short structures. In comparison to a common native plant in the eastern US, Pontederia cordata, snails clearly preferred to lay clutches on a widely distributed exotic, invasive plant (wild taro, Colocasia esculenta. Unexpectedly, smaller snails showed higher overall total fecundity as well as more eggs per clutch than larger snails. Therefore, hand removal efforts of large females may not be enough to slow down clutch production. Collectively, our results indicate that conservationists and managers should search emergent plants for P. insularum clutches carefully to guard against established populations [Current Zoology 57 (5: 630–641, 2011].

To determine the impact of a comprehensive medication synchronization program in an independent community pharmacy by (1) evaluating changes in Electronic Quality Improvement Platform for Plans and Pharmacies (EQuIPP) scores and (2) examining the change in monthly prescription volume. Independent community pharmacy in Morgantown, WV. Waterfront Family Pharmacy is a single-location independent community pharmacy located in Morgantown, WV. The pharmacy consists of four full-time pharmacists and is the primary practice site for one community pharmacy PGY-1 resident. The pharmacy provides a variety of clinical services, including vaccine administration, medication therapy management, and diabetes education services. In September 2014, Waterfront Family Pharmacy started a comprehensive medication synchronization program. Change in Electronic Quality Improvement Platform for Plans and Pharmacies (EQuIPP) scores and change in monthly prescription volume. At the end of 6 months there was improvement in all targeted EQuIPP scores. There was a 7% improvement in proportion of days covered (PDC) for cholesterol-reducing agents, a 9.5% improvement in PDC for oral glycemic agents, a 1.2% improvement in PDC for renin-angiotensin system antagonists, and a 1.8% reduction in the use of high-risk medications in the elderly. There was also an average increase in monthly prescription volume of 4.8% over the first 6 months after the implementation of the comprehensive medication synchronization program. The implementation of a comprehensive medication synchronization program in an independent community pharmacy may result in benefits including improved EQuIPP scores and increased prescription volume.

Giulia Gatti

2012-06-01

Full Text Available In the last ten years, European Directives stressed the necessity to assess the ecological status of marine habitats by means of ecosystem or landscape indicators, rather than just species or chemical ones. In this paper, the seascape approach to characterise and assess the ecological quality of coralligenous rocky shoals of Vado Ligure (Savona, Italy is introduced. This approach integrates biological, mesological and geomorphological information collected with a Rapid Visual Assessment technique (RVA. The RVA also optimised underwater operations in deep waters where coralligenous reefs usually develop and provided a sufficient amount of data collected by direct inspection. The seascape approach results are appropriate for the characterisation of the coralligenous shoals studied and for the assessment of their ecological quality. The quality of the assemblages was in general low, mainly due to high sedimentary stress; however, some exceptions showing a high ecological quality indicate that, with proper manage- ment tools, they would still have good potentialities of recovery.

Optimizing best management practices to control anthropogenic sources of atmospheric phosphorus deposition to inland lakes.

Science.gov (United States)

Weiss, Lee; Thé, Jesse; Winter, Jennifer; Gharabaghi, Bahram

2018-04-18

Excessive phosphorus loading to inland freshwater lakes around the globe has resulted in nuisance plant growth along the waterfronts, degraded habitat for cold water fisheries, and impaired beaches, marinas and waterfront property. The direct atmospheric deposition of phosphorus can be a significant contributing source to inland lakes. The atmospheric deposition monitoring program for Lake Simcoe, Ontario indicates roughly 20% of the annual total phosphorus load (2010-2014 period) is due to direct atmospheric deposition (both wet and dry deposition) on the lake. This novel study presents a first-time application of the Genetic Algorithm (GA) methodology to optimize the application of best management practices (BMPs) related to agriculture and mobile sources to achieve atmospheric phosphorus reduction targets and restore the ecological health of the lake. The novel methodology takes into account the spatial distribution of the emission sources in the airshed, the complex atmospheric long-range transport and deposition processes, cost and efficiency of the popular management practices and social constraints related to the adoption of BMPs. The optimization scenarios suggest that the optimal overall capital investment of approximately $2M, $4M, and $10M annually can achieve roughly 3, 4 and 5 tonnes reduction in atmospheric P load to the lake, respectively. The exponential trend indicates diminishing returns for the investment beyond roughly $3M per year and that focussing much of this investment in the upwind, nearshore area will significantly impact deposition to the lake. The optimization is based on a combination of the lowest-cost, most-beneficial and socially-acceptable management practices that develops a science-informed promotion of implementation/BMP adoption strategy. The geospatial aspect to the optimization (i.e. proximity and location with respect to the lake) will help land managers to encourage the use of these targeted best practices in areas that

Explanatory Factors of the Expansion of Recreation Function on the Bank of Danube River in Budapest

Pál Szabó

2015-10-01

Full Text Available In a city's development a river and riverbank played important role, however in recent decades the functions of them have changed, transformed, especially in major cities in the more developed countries, so the city administration was faced with a new phenomenon and geographical space: the changing riverbanks, and the utilization, development, revitalization of them has become a key issue. The various real processes showed the direction that these areas should be provided to the people, and the recreation service will be important for the local residents and tourists. Overall, the urban waterfront development is an increasingly important researched topic and policy. The question is: can we realize it in Budapest also nowadays? In recent years, those processes took place in Budapest, which resulted in an increasing utilization of the Danube and its banks for recreational functions. On the one hand, local social and economic processes have led to the waterfront sites released, on the other hand the needs of the residential population and tourists using the river and the riverside for recreational purposes have increased, and thirdly, the new city administration decided to renew the banks of the Danube, mainly to create new recreational areas. In this paper, we analyze these three factors, focusing on a past short period, because there is an exceptional cohesion between the processes, the needs and the new development goals. Two case studies are in the paper also: the Margaret Island as the oldest traditional recreational area in Budapest, and the Kopaszi-dam, as the newest and successful recreational area of Budapest. The analysis of the processes is based on data and literature, the analysis of the needs is based on a survey, and the analysis of the goals is based on the different development documents.

Full Text Available Islamic banking is relatively unknown to us. Although Islamic banking is only a segment or a 'niche' of the overall banking industry and banking market, its significance is rising steadily, and it will play an important role in the near future. Islamic banks, especially in light of the latest economic and political developments in Serbia (Etihad's acquisition of JAT, the project 'Belgrade Waterfront', etc. are not so far away from the Serbian banking system, so it is necessary to understand the basic forbidden categories in it, which is the main topic of this paper. Interest and gharar, which is a category in Islamic banking that is much broader, more comprehensive and more ambiguous than risk or speculation, are discussed in details.

Feeding Behavior of Subadult Sixgill Sharks (Hexanchus griseus at a Bait Station.

Directory of Open Access Journals (Sweden)

Bryan McNeil

Full Text Available This is the first in-situ study of feeding behaviors exhibited by bluntnose sixgill sharks. Bait was placed beneath the Seattle Aquarium pier situated on the waterfront in Elliott Bay, Puget Sound, Washington at 20m of water depth. Cameras and lights were placed around the bait box to record sixgill shark presence and behavior while feeding. Analysis of feeding behavior revealed that sixgills utilize a bite comparable to many other elasmobranchs and aquatic vertebrates, have the ability to protrude their upper jaw, change their feeding behavior based on the situation, and employ sawing and lateral tearing during manipulation. The versatility of their feeding mechanism and the ability of sixgills to change their capture and food manipulation behaviors may have contributed to the species' worldwide distribution and evolutionary success.

Sheet pile wall is a type of flexible earth retaining structure used in waterfront offshore structures, river protection work and temporary supports in foundations and excavations. Economy is an essential part of a good engineering design and needs to be considered explicitly in obtaining an optimum section. By considering appropriate embedment depth and sheet pile section it may be possible to achieve better economy. This paper describes optimum design of both cantilever and anchored sheet pile wall penetrating clay using a simple optimization tool Microsoft Excel ® Solver. The detail methodology and its application with examples are presented for cantilever and anchored sheet piles. The effects of soil properties, depth of penetration and variation of ground water table on the optimum design are also discussed. Such a study will help professional while designing the sheet pile wall penetrating clay.

A remote oil spill detection system for early warning of spills at waterfront or land-based facilities

International Nuclear Information System (INIS)

Parsons, M.J.; Stocky, W.D.; Westerlind, J.; Gram, H.R.; Jadamec, M.P.; Johnson, J.R.

1992-01-01

Early detection of spills during loading/unloading of crude oil or products at terminals or plants is essential for quickly stopping the spill and minimizing its impact. Such detection is particularly difficult at night or in remote areas. In order to provide a reliable and inexpensive spill detection system for such an application, a joint development process was undertaken to redesign an oil spill detection buoy system which had been successfully tested in the 1970s. The sensor's operation is based on the stimulated fluorescence of oil and selective wavelength detection of this fluorescence. The prototype system consists of a flotation buoy for remote deployment of the sensor, rechargeable battery supply, a land-based computer base station, and radio signal transmitter. The oil spill detection buoy was modified in 1991 and tested in the laboratory. Field trials are under way and tests to date have confirmed the unit's ability to detect oil and to differentiate between various types of oil and/or products, particularly if the software is alerted to the type of product being transferred. 2 figs

Florian Wiedmann

2015-08-01

Full Text Available This paper analyzes the different roots of current residential high-rise clusters emerging in new city districts along the coast of Bahrain’s capital city Manama, and the resulting urban planning and design challenges. Since the local real-estate markets were liberalized in Bahrain in 2003, the population grew rapidly to more than one million inhabitants. Consequently, the housing demand increased rapidly due to extensive immigration. Many residential developments were however constructed for the upper spectrum of the real-estate market, due to speculative tendencies causing a raise in land value. The emerging high-rise clusters are developed along the various waterfronts of Manama on newly reclaimed land. This paper explores the spatial consequences of the recent boom in construction boom and the various challenges for architects and urban planners to enhance urban qualities.

Time-Location Patterns of a Population Living in an Air Pollution Hotspot

International Nuclear Information System (INIS)

Wu, X.M.; Fan, Z.T.; Strickland, P.O.; Wu, X.M.; Fan, Z.T.; Strickland, P.O.

2010-01-01

This study characterized the time-location pattern of 107 residents living in air pollution hotspots, the Waterfront South and Cope wood/Davis Streets communities in Camden, NJ. Most residents in the two communities are minority and impoverished individuals. Results showed that employment status played the fundamental role in determining time-location patterns of this study population, and the variations of time-location pattern by season and by day-type were partially attributed to employment status. Compared to the National Human Activity Pattern Survey, the Camden cohort spent significantly more time outdoors (3.8 hours versus 1.8 hours) and less time indoors (19.4 hours versus 20.9 hours) than the general US population, indicating a higher risk of exposure to ambient air pollution for the Camden cohort. The findings of the study are important for understanding exposure routes and sources for the socio economically disadvantaged subgroup and ultimately help develop effective strategies to reduce community exposure to ambient air pollution in hotspots

Full Text Available The concept of prestige projects for cities is related to governments’ politics and visions.  Under the effects of globalization, central and local authorities have constructed   competitive cities. But these cities also have important historical qualities hence these processes have to be made by a holistic planning vision and conservation strategy. For instance, if a city waterfront skyline has a strong image; new constructions should be designed in harmony with the local topography and urban pattern. This paper is based on mathematical and computer based approaches for evaluating aesthetic qualities of city skylines. Therefore a case study on high rise buildings in the main prestige CBD of Istanbul is done. GIS models of Maslak-Zincirlikuyu axis is made and its past, present and future skylines are extracted by database querying and visual analysis. The skylines derived are finally measured by entropy analyses based on formal aesthetic  characteristics.

Full Text Available The city of Oslo, the Norwegian capital, is in the midst of executing a huge urban waterfront project in Bjørvika. This project has triggered several years of public debate. A key concept in the development project is “sustainable development”, but it is unclear what the concept implies. Several interests are involved which emphasise different goals and different values. In this article, a discourse analysis of the concept, in this particular context, is conducted. Five discourses are identified, which overlap as well as collide. Special attention is paid to how the respective discourses are related to a neoliberal form of government, and as part of the analysis, a discussion of how cultural heritage is used to increase the city’s attractiveness is undertaken. This article concludes that planning for a sustainable use of cultural heritage should imply establishing a reflective cultural policy not subsumed under economic sustainability.

of the coastline was carried out during the eighties, producing a number of marinas, theme parks and reconstruction of historical sites, which tend more to the standardization that the diversification of spaces for use of citizens. But this phenomenon does not belong exclusively to the last decades of the last century. Early interventions in the urban coastal fronts began with the discovery of the coast and leisure in the mid-nineteenth century. The discovery of the coast and leisure had been born since the late eighteenth century with the loss of fear of water, the new value given to science and currents of thought of the Enlightenment and the Romanticism of the time, which would Grand Tour of Europe. This assessment of costs is not reached the industrial cities until the last decades of the 1800s. Several European cities had previously coastal walks, but these were not from a planned urban spaces shared with the port and its aim was solely that of a contemplative walk. In Buenos Aires, as in other American cases, the start of the use of the coast and leisure was very early, compared with its parallel in Europe. While in New York and Chicago Fredrick Law Olmsted and Calvert Vaux were imposing a new use of public space and urban nature in contrast to the growth of cities, Domingo Faustino Sarmiento raised the first projects for the Tres de Febrero Park, the first coastal park the city of Buenos Aires. The authorities, architects and engineers who worked on the draft coastal parks saw these spaces as places of opportunity, as horizons for action, being edges of the city provided a special place for the development of public space. From an aesthetic professionals in charge saw the horizon as a scenic attraction, while from the practical side, the waterfront was the edge, so the city and an area of conflict between national and municipal authorities. In this article we will look at one of the most significant projects for the coast of Buenos Aires at the beginning of

Full Text Available The economy of Marzamemi, a small fishing village in the territory of Pachino, has always been linked to the sea. In the past the main activities were those connected with the tonnara, with the salting of fish and with the maritime commerce of the agricultural products. Later, the village became an important beach resort on a local scale. In the second half of the 1980s, the redevelopment of the waterfront, in the south of Marzamemi, stimulated a mainly local demand from young people attracted by some newly opened outlets connected, above all, with drink and food services. Then, in 1993 the cinema industry arrived in Marzamemi. Since then the old architectural heritage of the historic centre has been restored and used for tourism. Over the last few years, from the last ten days of July until the end of August, the tiny streets and the piazzas of the village have appeared overcrowded with tourists. A dynamism that the official statistical surveys are not able to describe.

Highlights: • FEA calculations of the stress distribution in SiC three-layer cladding. • Simulation of SiC mechanical performance under operation and accident conditions. • Failure probability analysis of SiC in steady-state and accident conditions. - Abstract: The silicon carbide cladding concept is currently under investigation with regard to increasing the accident tolerance and economic performance of light-water reactor fuels. In this work, the stress fields in the multi-layered silicon carbide cladding for LWR fuels are calculated using the commercial finite element analysis software ADINA. The material properties under irradiation are implemented as a function of temperature. The cladding is studied under operating and accident conditions, specifically for the loss-of-coolant accident (LOCA). During the LOCA, the blowdown and the reflood phases are modeled, including the quench waterfront. The calculated stresses along the cladding thickness show a high sensitivity to the assumptions regarding material properties. The resulting stresses are compared with experimental data and the probability of failure is calculated considering a Weibull model.

Full Text Available Abstract: Artificial Floating Islands (AFIs are human-made floating structures capable of supporting aquatic vegetation. Previous studies pointed out that most AFIs use aquatic plants to carry out improvement of water quality and ecological conservation. This study proposed a modified AFI system, named Green Water Farm (GWF, to increase the practical application value of traditional AFIs, and added a special design to create an environment that allows for terrestrial plants (including vegetables and flowers to grow and to carry out improvement of water quality and ecological conservation. The research site was located at the waterfront of Li-tze Lake in Pitou Township, Taiwan. A GWF was established to evaluate the improvement of water quality and ecological conservation. During one year, water quality and ecological conservation assessments were recorded to investigate the performance of GWF system. The research results showed that GWF could improve water quality and ecological conservation. In addition, the results of this study can provide useful information for more food sources for humans and animals, and increase biodiversity and ecological conservation.

According to the world traveller that have visited the old cities on the Java Island in the 15th century, the cities have a seaport. The sea port became a place for transit and stay until grown as a coastal city, Unfortunately, some of these cities have disappeared due to the process of secretions. Semarang in the 14th century also had a sea port as a landing area in Kampung Melayu. Recently the village no longer located in the coastal but in the middle of the city. How to prove that the area was a coastal area? By tracing some architectural remains, toponimy and comparing with the Javanese urban design pattern revealed the old phenomena in the past. Architectural sketches will make a clearly information about the old coastal line of Semarang. It is estimated that the seaport directly connected to the alun-alun / traditional square as central government. The city founders in Java puts the center of government using the same city spatial structure as waterfront city. The architecture remaining as a landmark of coastal city should be conserved.

Disaster caused by liquefaction is an important problem for the development of water-front because most of the places suffered from liquefaction disasters recently are located on sandy grounds. The damaged cases in the past due to liquefaction induced by earthquakes are grouped into: subsidence and inclination caused by the loss of supporting force of the ground, coming to the surface of buried structures due to excess pore hydrostatic pressure, destruction of lifeline accompanying the fluidization of ground, breakdown of bulkhead, retaining wall, etc. by increased earth pressure, sinking of soil structures, ground fissure, sliding, and immersion in floods and submergence of farms due to spouting of underground water. As regards prediction of liquefaction, description is made on the prediction of the occurrence of liquefaction and liquefaction prediction for which sedimentation environment is taken into consideration. Open-cut investigation can be said as the most effective means for accurate learning of the depth, thickness and sedimentation structure of liquefied layers. Liquefaction layers found in remains are also introduced. 16 refs., 6 figs.

Effects of the earthquake of March 27, 1964, at Seward, Alaska: Chapter E in The Alaska earthquake, March 27, 1964: effects on communities

Seward, in south-central Alaska, was one of the towns most devastated by the Alaska earthquake of March 27, 1964. The greater part of Seward is built on an alluvial fan-delta near the head of Resurrection Bay on the southeast coast of the Kenai Peninsula. It is one of the few ports in south-central Alaska that is ice free all year, and the town’s economy is almost entirely dependent upon its port facilities. The Alaska earthquake of March 27, 1964, magnitude approximately 8.3–8.4, began at 6:36 p.m. Its epicenter was in the northern part of the Prince William Sound area; focal depth was 20–50 km. Strong ground motion at Seward lasted 3–4 minutes. During the shaking, a strip of land 50–400 feet wide along the Seward waterfront, together with docks and other harbor facilities, slid into Resurrection Bay as a result of large-scale submarine landsliding. Fractures ruptured the ground for'severa1 hundred feet back from the landslide scarps. Additional ground was fractured in the Forest Acres subdivision and on the alluvial floor of the Resurrection River valley; fountaining and sand boils accompanied the ground fracturing. Slide-generated wares, possibly seiche waves, and seismic sea waves crashed onto shore; ware runup was as much as 30 feet above mean lower low water and caused tremendous damage; fire from burning oil tanks added to the destruction. Damage from strong ground motion itself was comparatively minor. Tectonic subsidence of about 3.6 feet resulted in low areas being inundated at high tide. Thirteen people were killed and five were injured as a result of the earthquake. Eighty-six houses were totally destroyed and 260 were heavily damaged. The harbor facilities were almost completely destroyed, and the entire economic base of the town was wiped out. The total cost to replace the destroyed public and private facilities was estimated at $22 million. Seward lies on the axis of the Chugach Mountains geosyncline.

The flank injection drive plays a dominant role in the exploitation of the BEB-oil fields. Therefore, 2-phase flow computer models were built up, adapted to a predominance of a single flow direction and combining a high accuracy of prediction with a low job time. Any case study starts with the partitioning of the reservoir into blocks. Then the statistics of the time-independent reservoir properties are analyzed by means of an IBM 360/25 unit. Using these results and the past production of oil, water and gas, a Fortran-program running on a CDC-3300 computer yields oil recoveries and the ratios of the relative permeabilities as a function of the local oil saturation for all blocks penetrated by mobile water. In order to assign kDwU/KDoU-functions to blocks not yet reached by the advancing water-front, correlation analysis is used to relate reservoir properties to kDwU/KDoU-functions. All these results are used as input into a CDC-660 Fortran program, allowing short-, medium-, and long-term forecasts as well as the handling of special problems.

Urbanization causes environmental impacts that threaten the health of aquatic communities and alter their recovery patterns. In this study, we evaluated the diversity of intertidal fish in six areas affected by urbanization (areas with native vegetation, deforested areas, and areas in process of restoration of vegetation) along an urban waterfront in the Amazon River. 20 species were identified, representing 17 genera, 14 families, and 8 orders. The different degrees of habitat degradation had a major effect on the composition of the fish fauna; the two least affected sectors were the only ones in that all 20 species were found. Eight species were recorded in the most degraded areas. The analysis revealed two well-defined groups, coinciding with the sectors in better ecological quality and degraded areas, respectively. The native vegetation has been identified as the crucial factor to the recovery and homeostasis of the studied ecosystem, justifying its legal protection and its use in the restoration and conservation of altered and threatened environments. These results reinforce the importance of maintaining the native vegetation as well as its restoration in order to benefit of the fish populations in intertidal zones impacted by alterations resulting from inadequate urbanization.

Tinti, S.; Armigliat, A.; Manucci, A.; Pagnoni, G.; Tonini, R.; Zaniboni, F.; Maramai, A.; Graziani, L.

The 2002 crisis of Stromboli culminated on December 30 in a series of mass failures detached from the Sciara del Fuoco, with two main landslides, one submarine followed about 7 min later by a second subaerial. These landslides caused two distinct tsunamis that were seen by most people in the island as a unique event. The double tsunami was strongly damaging, destroying several houses in the waterfront at Ficogrande, Punta Lena, and Scari localities in the northeastern coast of Stromboli. The waves affected also Panarea and were observed in the northern Sicily coast and even in Campania, but with minor effects. There are no direct instrumental records of these tsunamis. What we know resides on (1) observations and quantification of the impact of the waves on the coast, collected in a number of postevent field surveys; (2) interviews of eyewitnesses and a collection of tsunami images (photos and videos) taken by observers; and (3) on results of numerical simulations. In this paper, we propose a critical reconstruction of the events where all the available pieces of information are recomposed to form a coherent and consistent mosaic.

Powers of ten

Powers of Ten is a 1977 short documentary film written and directed by Charles Eames and his wife, Ray. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The idea for the film appears to have come from the 1957 book Cosmic View by Kees Boeke. The film begins with an aerial image of a man reclining on a blanket; the view is that of one meter across. The viewpoint, accompanied by expository voiceover, then slowly zooms out to a view ten meters across ( or 101 m in standard form), revealing that the man is picnicking in a park with a female companion. The zoom-out continues, to a view of 100 meters (102 m), then 1 kilometer (103 m), and so on, increasing the perspective—the picnic is revealed to be taking place near Soldier Field on Chicago's waterfront—and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe. The camera then zooms back in to the picnic, and then to views of negative pow...

The National Trust and the Heritage of Sydney Harbour

Full Text Available Campaigns to preserve the legacy of the past in Australian cities have been particularly focused on the protection of natural landscapes and public open space. From campaigns to protect Perth’s Kings Park and the Green Bans of the Builders Labourers Federation in New South Wales to contemporary controversies such as the Perth waterfront redevelopment, Melbourne’s East West Link, and new development at Middle Harbour in Sydney’s Mosman, heritage activists have viewed the protection and restoration of ‘natural’ vistas, open spaces and ‘scenic landscapes’ as a vital part of the effort to preserve the historic identity of urban places. The protection of such landscapes has been a vital aspect of establishing a positive conception of the environment as a source of both urban and national identity. Drawing predominantly on the records of the National Trust of Australia (NSW, this paper examines the formation and early history of the Australian National Trust, in particular its efforts to preserve and restore the landscapes of Sydney Harbour. It then uses that history as a basis for examining the debate surrounding the landscape reconstruction project that forms part of Sydney’s highly contested Barangaroo development.

Microbial sewage contamination associated with Superstorm Sandy flooding in New York City

O'Mullan, G.; Dueker, M.; Sahajpal, R.; Juhl, A. R.

2013-05-01

The lower Hudson River Estuary commonly experiences degraded water quality following precipitation events due to the influence of combined sewer overflows. During Super-storm Sandy large scale flooding occurred in many waterfront areas of New York City, including neighborhoods bordering the Gowanus Canal and Newtown Creek Superfund sites known to frequently contain high levels of sewage associated bacteria. Water, sediment, and surface swab samples were collected from Newtown Creek and Gowanus Canal flood impacted streets and basements in the days following the storm, along with samples from the local waterways. Samples were enumerated for the sewage indicating bacterium, Enterococcus, and DNA was extracted and amplified for 16S ribosomal rRNA gene sequence analysis. Waterways were found to have relatively low levels of sewage contamination in the days following the storm. In contrast, much higher levels of Enterococci were detected in basement and storm debris samples and these bacteria were found to persist for many weeks in laboratory incubations. These data suggest that substantial sewage contamination occurred in some flood impacted New York City neighborhoods and that the environmental persistence of flood water associated microbes requires additional study and management attention.

Environmentally sound disposal of wastes: Multipurpose offshore islands offer safekeeping, continuous monitoring of hazardous, nuclear wastes

International Nuclear Information System (INIS)

Tengelsen, W.E.

1995-01-01

Solid wastes have become a health threat to all municipalities and safe disposal costs are increasing for coastal cities. Onland dumps have become a continuing source of pollution, existing landfill sites should be eliminated. Ocean dumping is rules out because of the threat to aquatic resources but pollutants deep-sixed in the past should be isolated from the ocean environment before they further harm the aquatic food chain. And there are still no totally satisfactory solutions for nuclear waste disposal, especially for high-level wastes. A practical answer to our waste disposal problem is to build waterproof storage vault islands offshore to safely contain all past and futuer solid wastes so they would not mix with the ocean waters. Contaminated dredged spoil and construction materials can be safely included, in turn providing free shielding for nuclear waste stored in special vault chambers. Offshore islands can be built to ride out erthquakes and the ocean's waters provide a stable temperature environment. Building modular structures in large quantities reduces per-unit costs; implementing these islands creates quality jobs and an economic stimulus. The island's tops become valuable waterfront property for commercial, institutional, educational, infrastructural, and recreational uses; tenants and users provide the revenues that make this island concept self-supporting

Floating houses “lanting” in Sintang: Assessment on sustainable building materials

Science.gov (United States)

Susanto, D.; Lubis, M. S.

2018-03-01

One important element in the concept of sustainable building is the use of materials. The higher the use of sustainable material in building, the more sustained the building. Lanting is one type of floating construction, usually made from wood, that can be found in settlement along the river, such as in the city of Sintang, West Kalimantan. Lanting is still survive today because it is still used by community whose lives are tied to the river, and also because of its flexible nature that is able to function as a ‘water building’ as well as ‘land building’, and it is also movable, in addition for land limitation in some places. However, the existence of lanting settlements in the city of Sintang faces insistence because it is considered slum, polluting the environment, the scarcity of wooden materials, disturbing the beauty of the city, and threatened by the concretized river banks by local government. This paper discussed the sustainability of waterfront buildings in the city of Sintang in terms of material uses, through the assessment of ‘green-features’ of the main materials used. Assessment results show that wood is the most green building material and lanting is considered at the highest sustainability level for its use of wooden materials.

Reservoir shorelines : a methodology for evaluating operational impacts

Energy Technology Data Exchange (ETDEWEB)

Lawrence, M.; Braund-Read, J.; Musgrave, B. [BC Hydro, Burnaby, BC (Canada)

2009-07-01

BC Hydro has been operating hydroelectric facilities for over a century in British Columbia. The integrity and stability of the shorelines and slopes bordering hydroelectric reservoirs is affected by changing water levels in the reservoir, natural processes of flooding, wind and wave action and modification of groundwater levels. Establishing setbacks landward of the shoreline are needed in order to protect useable shoreline property that may be at risk of flooding, erosion or instability due to reservoir operations. Many of the reservoirs in British Columbia are situated in steep, glaciated valleys with diverse geological, geomorphological and climatic conditions and a variety of eroding shorelines. As such, geotechnical studies are needed to determine the operational impacts on reservoir shorelines. Since the 1960s BC Hydro has been developing a methodology for evaluating reservoir impacts and determining the land around the reservoir perimeter that should remain as a right of way for operations while safeguarding waterfront development. The methodology was modified in the 1990s to include geomorphological and geological processes. However, uncertainties in the methodology still exist due to limited understanding of key issues such as rates of erosion and shoreline regression, immaturity of present day reservoir shorelines and impacts of climate change. 11 refs., 1 tab., 7 figs.

2000-04-01

The environmental effects of the proposed construction and operation of up to three wind turbines on the Toronto waterfront are evaluated in accordance with the requirements of the Canadian Environmental Assessment Act (CEAA) and Regulations. The nine sections of the report provide background on the environmental assessment and the wind turbine project; provide justification for the project and describes alternative sites and wind turbine technologies; outlines the scope of the project; sketches the biophysical and socio-economic environment; presents an evaluation of the environmental impacts and proposed mitigating measures; describes the public consultation program that was carried out; summarizes the comments received from interested parties; presents the conclusion of the environmental impact assessment; and responds to the public comments received on the draft screening document. Most of the concerns raised involved avoidance reactions by birds, disruption or fragmentation of wildlife, the potential for high kill rate of small nocturnal migrants and young birds, and the effect of noise on breeding birds. The overall recommendation of the consultants is that the project is not likely to cause significant adverse environmental effects and its construction and operations should be authorized. 115 refs., 8 tabs., 2 figs.

Such nutrients as nitrogen and phosphorus discharged into lakes and rivers can cause organic contamination as a result of eutrophication in water areas if they are left as they are. However, they can be re-utilized as resources if they are utilized more effectively. This paper reports a hydroponic organism filtering method as a promising method of utilization thereof. It also explains transition in organism phase in rhizosphere and a water purification experiment. Such suspended matters as phytoplanktons in raw water are filtered and captured by roots of plants; such small animals as tendipedidae and physia live symbiotically in the rhizosphere; their excrements and nutrients are absorbed into and utilized by plants; and coexistence is made possible between diverse water-front environments including terrestrial systems and diverse living organisms. Cresson cultivation, observation on transition in the benthos composition, and a lake water purification experiment were carried out at the Kasumigaura Lake experimental facility. Various findings were acquired such that, in order to attain diverse coexistences including those with natural enemies and well-ventilated environments, a water channel of larger than a certain size is required. Results were also obtained that can be expected as an effective technique that may be used in public water areas. 3 refs., 4 figs.

Understanding the allure of big infrastructure: Jakarta’s Great Garuda Sea Wall Project

Directory of Open Access Journals (Sweden)

Emma Colven

2017-06-01

Full Text Available In response to severe flooding in Jakarta, a consortium of Dutch firms in collaboration with the Indonesian government has designed the 'Great Garuda Sea Wall' project. The master plan proposes to construct a sea wall to enclose Jakarta Bay. A new waterfront city will be built on over 1000 hectares (ha of reclaimed land in the shape of the Garuda, Indonesia’s national symbol. By redeveloping North Jakarta, the project promises to realise the world-class city aspirations of Indonesia’s political elites. Heavily reliant on hydrological engineering, hard infrastructure and private capital, the project has been presented by proponents as the optimum way to protect the city from flooding. The project retains its allure among political elites despite not directly addressing land subsidence, understood to be a primary cause of flooding. I demonstrate how this project is driven by a techno-political network that brings together political and economic interests, world-class city discourses, engineering expertise, colonial histories, and postcolonial relations between Jakarta and the Netherlands. Due in part to this network, big infrastructure has long constituted the preferred state response to flooding in Jakarta. I thus make a case for provincialising narratives that claim we are witnessing a return to big infrastructure in water management.

Odaiba seaside park is one of the most popular waterfronts in Tokyo Bay, but is easily affected by wet weather pollutant loads through combined sewer overflows (CSOs). The monitoring data of Escherichia coli clearly showed high faecal contamination after a rainfall event on 9-11 November 2007. We estimated the amounts of discharge volume and E. coli pollutant loads of urban rivers receiving CSO from rainfall chambers as well as pumping stations and primary effluent discharge. The result suggested that Sumida River and Meguro River were more influential to the Odaiba coastal area than other sources including the nearest wastewater treatment plant. Subsequently, we simulated the dynamic behaviour of E. coli by a three-dimensional (3D) hydro-dynamic and water quality model. The model simulation reproduced that E. coli concentration after the rainfall event increased rapidly at first and later gradually decreased. The simulations with and without inflow pollutant loads from urban rivers suggested that the E. coli concentration can be influenced by the Meguro River just after the rainfall event and Sumida River about 1 week later. From the spatial and temporal distribution of surface E. coli concentration, after at least 6 days from the rainfall event, high faecal contamination spread to the whole of the coastal area.

Ecological value of submerged breakwaters for habitat enhancement on a residential scale.

Scyphers, Steven B; Powers, Sean P; Heck, Kenneth L

2015-02-01

Estuarine shorelines have been degraded since humans arrived in the coastal zone. In recent history, a major cause of habitat degradation has been the armoring of shorelines with vertical walls to protect property from erosive wave energy; however, a lack of practical alternatives that maintain or enhance ecological function has limited the options of waterfront residents and coastal zone managers. We experimentally investigated the habitat value of two configurations of submerged breakwaters constructed along an eroding shoreline in northwest Mobile Bay, AL (USA). Breakwaters comprised of bagged oyster shell or Reef Ball™ concrete domes were built by a community-based restoration effort. Post-deployment monitoring found that: bagged oyster breakwaters supported much higher densities of live ribbed mussels than Reef Ball breakwaters; both breakwater configurations supported increased species richness of juvenile and smaller fishes compared to controls; and that larger fishes did not appear to be affected by breakwater presence. Our study demonstrates that ecologically degraded shorelines can be augmented with small-scale breakwaters at reasonable cost and that these complex structures can serve as habitat for filter-feeding bivalves, mobile invertebrates, and young fishes. Understanding the degree to which these structures mitigate erosive wave energy and protect uplands will require a longer time frame than our 2-year-long study.

Creative Spaces in China: The Case of PRD

Zielke, Philipp

2012-03-01

Full Text Available During the past decade, China experienced a fundamental shift in terms of its economic policy from a pure fo-cus on export-led growth to new development approaches towards a more knowledge- and innovation-based economy. In this context of the “Second Transition”, the urban planning authorities of Chinese metropoles have increasingly turned their attention towards the development of so-called creative spaces. This research note argues that creative spaces have become important urban symbols for the shift from “Made in China” to “Created in China”. It shows that the expansion of creative spaces has started comparatively late in the Pearl River Delta and analyses and compares the development of four distinct spatial clusters of creativity in Shenzhen and Guangzhou. These spaces are currently being developed on de-relict manufacturing or warehouse sites and boosted by the local government. At these sites – in some cases along water-front areas – media and design companies, fashionable restaurants and bars for the emerging urban middle class can be found. The paper demonstrates the powerful relationships between local administration and real estate developers and shows at the same time that the overall development of creative spaces in the Pearl River Delta Region is just beginning.

Nanning City, as one of the first batch of experimental sponge cities in China, has undertaken exploration and practice on sponge city planning, construction, and management. The sponge city master plan of Nanning City establishes an urban ecological spatial pattern in order to protect the security of the sponge base. The sponge city construction strategy has also proposed an overall construction strategy of a sponge city in line with urban development features. Through the systematic analysis and planning, a “23+10+202” pattern of sponge city construction has been formed. “23” represents 23 drainage basins, in which major sponge facilities such as storage facilities, waterfront buffer zones, wetland parks, ecological rainwater corridor and sponge parks are allocated. “10” represents 10 sponge functional zones, which provide important reference for the establishment of sponge city construction index system. “202” represents 202 management units, which decomposes the general objective and provides technical support not only for sponge city construction and management, but also for the implementation of general objectives in the regulatory plan as well.

The South Wilmington Area (SWA), which is comprised of 200 acres of multi-use urban lowlands adjacent to the Christina River, is a brownfields area that has been targeted for redevelopment/restoration as part of a major waterfront revitalization project for the City of Wilmington, Delaware. The vision for this riverfront development, which is being promoted by a state-funded development corporation, includes plans for a new harbor, convention and entertainment facilities, upscale residences, an urban wildlife refuge, and the restoration of the Christina River. However, the environmental quality of the SWA has been seriously impacted by an assortment of historic and current heavy industrial land-uses since the late 1800's, and extensive environmental cleanup of this area will be required as part of any redevelopment plan. Given that the environmental cleanup cost will be a major factor in determining the overall economic feasibility of brownfield development in the SWA, a reliable means of estimating potential preliminary remedial costs, without the expense of costly investigative and engineering studies, was needed to assist with this redevelopment initiative. The primary chemicals-of-concern (COCs) area-wide are lead and petroleum compounds, however, there are hot-spot occurrences of polynuclear aromatic hydrocarbons (PAHs), PCBs, and other heavy metals such as arsenic and mercury

Historical records of mercury contamination in dated sediment cores from Sinclair Inlet are coincidental with activities at the U.S. Navy Puget Sound Naval Shipyard; peak total mercury concentrations occurred around World War II. After World War II, better metallurgical management practices and environmental regulations reduced mercury contamination, but total mercury concentrations in surface sediment of Sinclair Inlet have decreased slowly because of the low rate of sedimentation relative to the vertical mixing within sediment. The slopes of linear regressions between the total mercury and total organic carbon concentrations of sediment offshore of Puget Sound urban areas was the best indicator of general mercury contamination above pre-industrial levels. Prior to the 2000-01 remediation, this indicator placed Sinclair Inlet in the tier of estuaries with the highest level of mercury contamination, along with Bellingham Bay in northern Puget Sound and Elliott Bay near Seattle. This indicator also suggests that the 2000/2001 remediation dredging had significant positive effect on Sinclair Inlet as a whole. In 2007, about 80 percent of the area of the Bremerton naval complex had sediment total mercury concentrations within about 0.5 milligrams per kilogram of the Sinclair Inlet regression. Three areas adjacent to the waterfront of the Bremerton naval complex have total mercury concentrations above this range and indicate a possible terrestrial source from waterfront areas of Bremerton naval complex. Total mercury concentrations in unfiltered Sinclair Inlet marine waters are about three times higher than those of central Puget Sound, but the small numbers of samples and complex physical and geochemical processes make it difficult to interpret the geographical distribution of mercury in marine waters from Sinclair Inlet. Total mercury concentrations in various biota species were compared among geographical locations and included data of composite samples, individual

Full Text Available This paper addresses an exploratory practice undertaken by the authors in a co-taught class to hybridize theory, research and practice. This experiment in critical transdisciplinary design education took the form of a “critical studio + practice-based seminar on public space”, two interlinked classes co-taught by landscape architect Elliott Maltby and environmental psychologist Gabrielle Bendiner-Viani at the Parsons, The New School for Design. This design process was grounded in the political and social context of the contested East River waterfront of New York City and valued both intensive study (using a range of social science and design methods and a partnership with a local community organization, engaging with the politics, issues and human needs of a complex site. The paper considers how we encouraged interdisciplinary collaboration and dialogue between teachers as well as between liberal arts and design students and developed strategies to overcome preconceived notions of traditional “studio” and “seminar” work. By exploring the challenges and adjustments made during the semester and the process of teaching this class, this paper addresses how we moved from a model of intertwining theory, research and practice, to a hybrid model of multiple ways of doing, a model particularly apt for teaching public space. Through examples developed for and during our course, the paper suggests practical ways of supporting this transdisciplinary hybrid model.

Assessment of the health risks resulting from exposure to ambient polycyclic aromatic hydrocarbons (PAH) is limited by a lack of environmental exposure data among the general population. This study characterized personal exposure and ambient concentrations of PAH in the Village of Waterfront South (WFS), an urban community with many mixed sources of air toxics in Camden, New Jersey, and CopeWood/Davis Streets (CDS), an urban reference area located ~1 mile east of WFS. A total of 54 and 53 participants were recruited from non-smoking households in WFS and CDS, respectively. In all, 24-h personal and ambient air samples were collected simultaneously in both areas on weekdays and weekends during summer and winter. The ambient PAH concentrations in WFS were either significantly higher than or comparable to those in CDS, indicating the significant impact of local sources on PAH pollution in WFS. Analysis of diagnostic ratios and correlation suggested that diesel truck traffic, municipal waste combustion and industrial combustion were the major sources in WFS. In such an area, ambient air pollution contributed significantly to personal PAH exposure, explaining 44–96% of variability in personal concentrations. This study provides valuable data for examining the impact of local ambient PAH pollution on personal exposure and therefore potential health risks associated with environmental PAH pollution.

This study looks at the interrelation of human-biometeorological conditions, physiological thermal stress and subjective thermal perception in the design and use of a new waterfront park in Tel-Aviv, Israel. Our initial assumption was that the park's design would embody a comprehensive response to the area's ever-increasing heat stress and water shortage. However, almost half of it is covered by grass lawns, irrigated with fresh water, while the remaining area is mainly covered with concrete paving, with minimal shading and sparse trees. We hypothesized that stressful thermal conditions would prevail in the park in the summer season and would be expressed in a high discomfort perception of its users. Thermo-physiological stress conditions in a typical summer month were compared with the subjective comfort perceptions of pedestrians surveyed in the park. It was found that even during mid-day hours, the level of thermal stress tends to be relatively mild, owing largely to the strong sea breeze and despite the high intensity of solar radiation. Moreover, it appears that the largely favorable perception of comfort among individuals may also result from socio-cultural aspects related to their satisfaction with the park's aesthetic attractiveness and in fact its very existence. Adaptive planning is proposed for such vulnerable regions, which are expected to experience further aggravation in thermal comfort due to global as well as localized warming trends.

Full Text Available This essay outlines and analyses contemporary image representations of Ndabeni (also called kwa-Ndabeni, a location near Cape Town where a group of people became confined between 1901 and 1936 following an outbreak of the bubonic plague in the city. This location was to shape Cape Town's landscape for a little less that thirty-five years, accommodating people who were forcibly removed from the Cape Town docklands and from District Six. Images representing this place have been produced, archived, recovered, modified, reproduced and circulated in different ways and contexts. Ndabeni has become public knowledge through public visual representations that have been produced across a range of sites in post-apartheid Cape Town. I focus on three sites: the Victoria and Alfred Waterfront, the District Six Museum, and the Eziko Restaurant and Catering School. In each case I analyse the processes through which the Ndabeni images in question have been used and reused over time in changing contexts. I analyse the 'modalities' in which these images have been composed, interpreted and employed and in which knowledge has been mediated. I explore the contents and contexts of the storyboards and exhibition panels that purport to represent Ndabeni. Finally, I discuss potential meanings that could be constructed if the images could be read independent of the texts.

On the Waterfront Italo Falcomatà of Reggio Calabria you can admire the most extensive tract of the walls of the Hellenistic period of ancient city of Rhegion. The so-called Greek Walls are one of the most significant and visible traces of the past linked to the culture of Ancient Greece in the site of Reggio Calabria territory. Over the years this stretch of wall has always been a part, to the reconstruction of Reggio after the earthquake of 1783, the outer walls at all times, restored countless times, to cope with the degradation of the time and the adjustments to the technical increasingly innovative and sophisticated siege. They were the subject of several studies on history, for the study of the construction techniques and the maintenance and restoration of the same. This note describes the methodology for the implementation of a three-dimensional model of the Greek Walls conducted by the Geomatics Laboratory, belonging to DICEAM Department of University “Mediterranea” of Reggio Calabria. 3D modeling we made is based on imaging techniques, such as Digital Photogrammetry and Computer Vision, by using a drone. The acquired digital images were then processed using commercial software Agisoft PhotoScan. The results denote the goodness of the technique used in the field of cultural heritage, attractive alternative to more expensive and demanding techniques such as laser scanning.

Full Text Available Coastal resources play a vital role in Maine’s cultural and economic wellbeing, contributing an estimated 168 billion dollars to the Maine economy. There are numerous risks to the sustainability of Maine’s shellfishing industry and working waterfront, including pathogenic bacterial pollution. In this study, we ask a broad fundamental question central to science and environmental journalism: how do newspapers cover localized environmental risks and what are the implications of those approaches? Utilizing the northeastern US state of Maine’s shellfishing industry as an exemplar environmental issue, this study examines how Maine’s two most read newspapers, the Bangor Daily News and the Portland Press Herald, report on bacterial contamination and shellfish. This study examines the themes that are present in the newspaper articles published about shellfish between 2003 and 2014 and analyses the types of sources journalists used within their coverage of these issues. Overall, we identified seven key themes: economic concerns, environmental impacts, political and regulatory issues, issues of public health and safety, reference to cultural values, technical and infrastructural issues, and aesthetic concerns. The most commonly cited individuals in the articles were government officials and scientists. The least cited groups were clammers and shellfishermen, general citizens, advocacy groups, and worm diggers. Implications for local coverage of environmental risks in Maine, science communication, and sustainability science are discussed.

Full Text Available Abu Dhabi is in the process of urbanizing a group of Islands that surround its northern and eastern coastlines. Al-Lulu, Al-Saadiyat, Al- Maryah, Al-Reem and Yas Islands are all new urban enclaves that were desert islands and marshlands yet, have been developed over the past decade to urban islands that include epic and entertainment centres such as the Abu Dhabi Louvre, Guggenheim Museum, Ferrari World, NYU Abu Dhabi, the Paris Sorbonne Abu Dhabi in addition to iconic and exclusive waterfront residential units. These new islands re-brand the image of the main archipelago of Abu Dhabi that for decades retained a grid street pattern and pragmatic concrete blocks created in the late 1970s. The new urban islands transform Abu Dhabi’s image into a multinational modern Arab city seeking to become part of the global city network. Abu Dhabi’s new urban islands also act as breakwaters that protect the main archipelago’s coastline from erosion resulting from tidal change, because they are designed to include concrete and stone breakwater barriers. This paper represents a cross-disciplinary research between Civil Engineering and Architecture Departments in an attempt to explore the emerging infrastructure and urban expansion of Abu Dhabi from a multi-disciplinary perspective. We also highlight through simulating the effect of breakwaters on wave heights two scenarios for Al-Lulu Island the importance of these new barrier Islands on the urban expansion of Abu Dhabi.

...The Coast Guard is disestablishing the permanent safety zone at Trunkline LNG in Lake Charles, LA and replacing it with a security zone with new boundaries. The Coast Guard is also establishing two additional permanent security zones on the waters of the Calcasieu River for the mooring basins at Cameron LNG in Hackberry, LA and PPG Industries in Lake Charles, LA. The Coast Guard is also disestablishing the Calcasieu River ship channel moving safety zone and replacing it with a moving security zone. The revised moving security zone extends channel edge to channel edge on the Calcasieu Channel and shoreline to shoreline on the Calcasieu River, 2 miles ahead and 1 mile astern of certain designated vessels while in transit on the Calcasieu Channel or Calcasieu River. Meeting, crossing or overtaking situations are not permitted within the security zone unless specifically authorized by the Captain of the Port. The moving security zone may commence at any point while certain vessels are transiting the Calcasieu Channel or Calcasieu River on U.S. territorial waters (12 nautical miles) in the Captain of the Port (COTP) Port Arthur zone. These security zones are needed to protect vessels, waterfront facilities, the public, and other surrounding areas from destruction, loss, or injury caused by sabotage, subversive acts, accidents, or other actions of a similar nature. Unless exempted under this rule, entry into or movement within these security zones is prohibited without permission from the Captain of the Port or a designated representative.

Source characteristics of volatile organic compounds during high ozone episodes in Hong Kong, Southern China

Full Text Available Measurements of Volatile Organic Compounds (VOC are analyzed to characterize the sources impacting the Hong Kong area. The ratios of different VOC species, m,p-xylenes-to-ethylbenzene, C₆H₁₄-to-toluene and p-xylene-to-total xylenes are used for diagnostic analyses. Photochemical age analysis shows that the sources of reactive aromatics, the most important contributor to the photochemical reactivity, do not appear to be preferentially located in downtown Hong Kong. In addition, they do not appear to be dominated by mobile emissions based on the analyses of speciated VOC data from an earlier study, but related to industrial, waterfront, and fuel-storage activities. The ratios, p-xylene-to-total xylenes and dSO₂/dNO_y, suggest that the anomalously high pollutant concentrations in western Hong Kong in the early morning hours of two episode days appear to have come from transport of urban-type emissions. Comparison of observed ambient ratios of selected VOC and their ratios in the speciated VOC emission inventories for Hong Kong and adjacent Pearl River Delta (PRD Region gives mixed results. The observed ratio C₆H₁₄-to-toluene is consistent with the speciated version of the VOC emission inventory. The ratios of selected alkanes are not. This may be caused by the inaccuracies in the inventory and/or the speciation method.

Genetic connectivity between land and sea: the case of the beachflea Orchestia montagui (Crustacea, Amphipoda, Talitridae) in the Mediterranean Sea.

We examined patterns of genetic divergence in 26 Mediterranean populations of the semi-terrestrial beachflea Orchestia montagui using mitochondrial (cytochrome oxidase subunit I), microsatellite (eight loci) and allozymic data. The species typically forms large populations within heaps of dead seagrass leaves stranded on beaches at the waterfront. We adopted a hierarchical geographic sampling to unravel population structure in a species living at the sea-land transition and, hence, likely subjected to dramatically contrasting forces. Mitochondrial DNA showed historical phylogeographic breaks among Adriatic, Ionian and the remaining basins (Tyrrhenian, Western and Eastern Mediterranean Sea) likely caused by the geological and climatic changes of the Pleistocene. Microsatellites (and to a lesser extent allozymes) detected a further subdivision between and within the Western Mediterranean and the Tyrrhenian Sea due to present-day processes. A pattern of isolation by distance was not detected in any of the analyzed data set. We conclude that the population structure of O. montagui is the result of the interplay of two contrasting forces that act on the species population genetic structure. On one hand, the species semi-terrestrial life style would tend to determine the onset of local differences. On the other hand, these differences are partially counter-balanced by passive movements of migrants via rafting on heaps of dead seagrass leaves across sites by sea surface currents. Approximate Bayesian Computations support dispersal at sea as prevalent over terrestrial regionalism.

Portland's experience with land use tools to promote green roofs

International Nuclear Information System (INIS)

Johnson, M.

2004-01-01

In the late 1990s, the City of Portland, Oregon faced environmental challenges that prompted the City to mandate environmentally sensitive development. Several programs were developed in response to these challenges, some of which resulted in the creation of land use policies and incentives that promote green roofs. Zoning code provisions were adopted in 2001 to promote eco-roofs in an effort to reduce stormwater runoff, mitigate urban heat island effects, provide habitat for birds, and improve air quality and energy efficiency. The Central City Fundamental Design Guidelines were also revised to encourage eco-roof development. In 2002, the South Waterfront Plan was created to integrate ecological design into an urban environment through sustainability principles and practices. Land use tools were developed to introduce developers to an approach that reduced energy costs and stormwater costs, while also contributing to a project's marketability. These tools were created with the support of programs and policies such as the CSO (Combined Sewer Overflow) Program; eco-roof research which began in 1995 to determine the stormwater management potential of eco-Green roofs; technical assistance to encourage and highlight sustainable development practices; the Stormwater Management Manual that set standards for the amount and quality of stormwater runoff leaving development sites; the G/Rated Program that offers resources for green building practices; the Green Investment Fund that supports the G/Rated Program; and, the Portland Development Commission Green Building Policy financing tool for earth-friendly designs and materials. 34 refs., 2 figs

National brownfield redevelopment strategy: Executive summary

NONE

2003-02-01

Brownfields refer to contaminated land which lies unused and unproductive. The potential for rejuvenation of such lands exist, which would bring health and economic benefits to local communities, as numerous sites are located in urban areas. The National Round Table on the Environment and the Economy (NRTEE) agreed, upon request from the government of Canada. to develop a redevelopment strategy designed specifically for brownfields. It is estimated that there are some 30,000 brownfield sites in Canada, such as former railway yards, decommissioned refineries, old waterfronts and riverbanks, crumbling warehouses, abandoned gas stations, former dry cleaners and other commercial properties where toxic substances were either used or stored. The rejuvenation of such sites results in economic, social, and environmental benefits through the creation of numerous jobs, millions of dollars in additional property taxes, as well as thousands of new housing units. There are several challenges in cleaning up those sites: lack of access to capital, regulatory liability risk, civil liability risk, limited access to insurance protection, regulatory delays, stigma and risk perception, and lack or awareness among many key public and private sector groups. This document presents the national strategy developed to address those issues. Three strategic directions have been identified for action: (1) applying strategic public investments to address up front costs, (2) establishing an effective public policy regime for environmental liability and risk management, and (3) building capacity for and community awareness of brownfield redevelopment. Recommendations and the rationale were presented under each proposal.

In molte città contemporanee, la ristrutturazione economica e la riqualificazione urbana posto gli eventi al centro delle strategie di cambiamento.Spesso, tuttavia, questi interventi richiedono un tempo molto breve e investimenti elevati, che non sempre hanno un effetto duraturo nel tempo, con edifici e spazi che, dopo l'evento, si trasformano in spazi pubblici inutilizzati o edifici che devono essere riqualificati.Le città costiere rappresentano un campo privilegiato di analisi per approfondire le dinamiche dei processi di sviluppo e di rigenerazione connessi ad eventi.Alcune città hanno potenziato la propria identità marittima sviluppando attività legate alla vela, eventi sportivi velici e la nautica da diporto, promuovendo la crescita sociale ed economica, nonché la riqualificazione delle aree dismesse. Il recupero di questa identità è il punto di partenza per migliorare la qualità urbana e attrarre grandi eventi, sviluppando la competitività in un circolo virtuoso.L'immagine di queste città è migliorata, a livello locale, nazionale e internazionale, promuovendo processi di riqualificazione che hanno coinvolto i responsabili politici, gli utenti della città e gli stakeolders.Nei casi di successo, i grandi e i piccoli eventi rappresentano tessere di un mosaico più ampio, una visione della città fondata sulla identità marittima e il progetto di riqualificazione del waterfront è stato in grado di rafforzare le relazioni con le aree urbane esistenti.Il saggio propone due casi di studio europei, le città di Lorient e Valencia, mettendo in evidenza il ruolo della pianificazione a lungo termine nei processi di rigenerazione.La città di Lorient, in linea con la sua storia, ha iniziato un processo di rigenerazione

Liquefaction susceptibility of fine-grained soils: preliminary study report. Final report, September 1985-March 1986

Chang, N.Y.

1987-09-01

Soil liquefaction, a hazardous ground failure induced by strong motion earthquakes, can cause catastrophic damage to structures such as dams, bridges, power plants, and water-front structures and may involve great losses of life. Examples of liquefaction and resulting damage were observed during the Alaska (1964), Niigata, Japan (1964), and Tangshan, China (1976), earthquakes. Ground failure due to earthquake-induced soil liquefaction may manifest itself as excessive settlement, loss of bearing capacity, sand boiling, and flow slides. The liquefaction potential of clean sands has been studied extensively for the last two decades. However, case histories revealed that liquefied sands were seldom clean. They may contain various percentages of silt or clay or both. In fact, the Chinese observation in the Tansghan earthquake indicated that some cohesive soils may have liquefied. If this indeed had happened, then structures underlain by fine-grained soils, with a marginal safety factor based on the liquefaction criteria normally applied to sands, may actually be unsafe. Thus there is an urgent need for establishing new criteria for the liquefaction susceptibility of soils to include those identified as fine-grained. The author, Professor N.Y. Chang of the University of Colorado at Denver, visited several Chinese agencies and and universities in and near Beijing, China, in the summer of 1985 in an attempt to investigate and verify reported data on the liquefaction of cohesive soils during the Tangshan earthquake of 1976 and to negotiate cooperative research into the problem. This report presents the result of supportive literature review and the findings of the China trip.

Spectral properties of plant leaves pertaining to urban landscape design of broad-spectrum solar ultraviolet radiation reduction

Science.gov (United States)

Yoshimura, Haruka; Zhu, Hui; Wu, Yunying; Ma, Ruijun

2010-03-01

Human exposure to harmful ultraviolet (UV) radiation has important public health implications. Actual human exposure to solar UV radiation depends on ambient UV irradiance, and the latter is influenced by ground reflection. In urban areas with higher reflectivity, UV exposure occurs routinely. To discover the solar UV radiation regulation mechanism of vegetation, the spectral reflectance and transmittance of plant leaves were measured with a spectrophotometer. Typically, higher plants have low leaf reflectance (around 5%) and essentially zero transmittance throughout the UV region regardless of plant species and seasonal change. Accordingly, incident UV radiation decreases to 5% by being reflected and is reduced to zero by passing through a leaf. Therefore, stratified structures of vegetation are working as another terminator of UV rays, protecting whole terrestrial ecosystems, while vegetation at waterfronts contributes to protect aquatic ecosystems. It is possible to protect the human population from harmful UV radiation by urban landscape design of tree shade and the botanical environment. Even thin but uniformly distributed canopy is effective in attenuating UV radiation. To intercept diffuse radiation, UV screening by vertical structures such as hedges should be considered. Reflectivity of vegetation is around 2%, as foliage surfaces reduce incident UV radiation via reflection, while also eliminating it by transmittance. Accordingly, vegetation reduces incident UV radiation to around 2% by reflection. Vegetation influence on ambient UV radiation is broad-spectrum throughout the UV region. Only trees provide cool UV protective shade. Urban landscapes aimed at abating urban heat islands integrated with a reduction of human UV over-exposure would contribute to mitigation of climate change.

Full Text Available Being exposed to the multiple needs of their contemporary users, the cities from all over the world have been forced to activate all capacities in order to intensify their land use, adjust their urban structure and reinvent some forgotten segments (ex-industrial areas, traffic nodes, docks, waterfronts as generators of multilayered transformations and mutations. Therefore, the purpose of this paper is to analyze and compare different approaches of this practice, as well as to emphasize the relation between the applied global imperatives/trends/myths, local conditions and limitations, and the outcomes. Consequently, the first part will be structured around four key-words which often "justify" and activate multifunctional and intensive land use - connectivity, profit, identity and sustainability. The second part will be focused on the case of Serbia, describing a unique postmodern example of the fusion of local and global influences. The multifunctional land use in this case is a result of numerous political and economic problems, the plurality of values and (illegal transformations of urban structure. This condition has finally affected the rising need for urban redesign, the re-organization and revitalization of city centers, fringe areas, devastated and degraded urban zones, as well as the development of existing transport and communication networks i.e. improvement of urban and regional connectivity. Additionally, the "model of territorial values" will be explained as a planning tool which could be used in order to increase the level of urban attractiveness, define urban parameters and estimate land values. .

Full Text Available In response to globalization and economic competitiveness, Malaysia launched six economic development corridors, covering all the potential areas in Malaysia, and Johor Bahru is one of them. Iskandar Malaysia was launched in 2006 for future economic development in the country as well as to cater the needs of Johor Bahru to modernize its urban and economic infrastructure. Situated in a strategic location and space, Iskandar Malaysia is targeted to be the player of catalytic investment role that will bring direct and indirect investment to Johor. The whole landscape of Johor Bahru is now transforming dramatically, thus worrying the locals and the environmentalists. Environmental issues as well as the concern for social inequality issues have been raised by the locals. Hence, the aim of this study is to address the issues created by the rapid development of Iskandar Malaysia, particularly in Johor Bahru and Nusajaya. The objectives of this paper are to assess the consequences of the coastal land reclamation for Danga Bay waterfront city development and to identify the impact of new-build gentrification towards the local people. The research identifies key social and economic issues and the impacts of these issues have also been identified. To achieve the objective of the study a detailed review on secondary data has been done. The study found that more cooperation and attention from the local authorities, stakeholders and public is needed to ensure urban regeneration and to achieve the objective of social inclusiveness as promised by the vision of Iskandar Malaysia.

Full Text Available OBJECTIVE: This study aimed to describe the trade and microbiological quality of boiled quail eggs on the waterfront of Salvador , Bahia, Brazil, from the child labor perspective. METHODS: This cross-sectional study administered semi-structured questionnaires to 40 underage vendors and performed the microbiological assessment of 40 quail egg samples as follows: mesophilic aerobic microorganism count, coagulase-positive staphylococcus count, estimation of the most probable number of total and thermotolerant coliforms/Escherichia coli, and testing for Salmonella spp.. The results were compared with the standards provided by the Resolution RDC nº 12/2001, National Sanitary Surveillance Agency. RESULTS: The vendors were mostly female (57.5% students (95.0% aged 8 to 17 years. The most common reason for working was supplementation of the family income (57.5%. The mean gross income was R$38.31/day. Most of them presented inadequate personal hygiene but they recognized that foods could cause diseases. Many (47.5% vendors reported washing their hands up to twice daily. Mean mesophilic aerobic microorganism and coagulase-positive staphylococcus counts were 2.43 and 2.01 log colony-forming unit/g, respectively, and the estimated thermotolerant coliform contamination was 0.98 log most probable number/g. Escherichia coli was found in 15.0% of the samples and none contained Salmonella spp. Most (55.0% samples were noncompliant with the legislation. CONCLUSION: The results evidenced the presence of minors selling quail eggs on beaches of Salvador and suggest risk to consumers' health because of the detected contamination and vendors' ignorance of principles of hygiene.

Avicennia marina becomes important as wave attenuation, a form of abrasion antidote. Transect-Square and Spot-Check methods were used to determine the existing condition of A.marina mangrove forests. Autocad program, coordinate converter, Google Earth, Google Map, and Arc View were applied in process of making mangrove distribution map. In western of research location exactly at Station 1 and Station 2, the density value of mangrove was 450 and 825 tree ha-1, respectively with sparse category because they were contaminated by waste and litter. In eastern of research location namely Station 3, Station 4, and Station 5 the mangroves grow well with density value of 650 (sparse, 1,500 (very dense, and 1,200 tree ha-1 (fair, respectively, eventhough the contamination still happened. The mangrove forests around the stations do not function as wave attenuation because there were many waterfront constructions which have replaced the function of mangrove forests to damp the wave. In short, it can be stated that the mangrove's function has changed in a case of wave attenuation. The function of mangrove forests is not determined by mangrove forest density but it is determined by mangrove's free position.

THE U.S.S. OLYMPIA: GLORIOUS PAST, DECAYED PRESENT AND HOPEFUL FUTURE (ABSTRACT

Full Text Available This paper traces the naval history of the U.S.S. Olympia and incorporates many photographs to display the current condition of the ship. The paper begins with a brief history of the U.S.S. Olympia and its role in the Spanish-American War, its part as the flagship of the Caribbean, its World War I work and its role in the ill conceived Murmansk intervention and its more successful participation in the Trau pacification of Italians and Yugoslavs; its feature part in the bombing experiments of Billy Mitchell and transporting the Unknown Soldier from France to Washington in a most hazardous journey. It was decommissioned in 1931 and is currently part of the Independence Seaport Museum in Philadelphia. It is docked in the Delaware River about eight blocks from Independence Hall and within easy walking distance of other historical attractions. Similar to the Constitution in Boston the U.S.S. Olympia could be an important part of the Philadelphia waterfront.The ship although in disrepair has a living history crew, which portray the work of the Spanish American seamen. They perform the various drills, play music of the time and prepare food then served. Of particular import is the economics of the Olympia. What is required and what initiatives have been undertaken to restore the Olympia? Rough cost-benefit data is presented to illustrate the advantages and costs of preservation.Finally the paper looks at the regional development of the Philadelphia Center City and the way in which preservation efforts can complement other initiatives to develop the area.

Full Text Available In June 2011, the Venetians Engineers organized a conference entitled: The Eighth district. The Laguna as a connection matrix. In a world where the concept of “city”, which has become improper, applies to so-called historical centers that increasingly large conurbations, much of the Laguna is peripheral space, where inedited stories and resonant events living with full-blown environmental degradation and decay culture, make it a place of margin. Today, the lagoon and coastal areas are a continuous with the water spaces and islands that separate them, facing with unfinished waterfront towards brackish non-places. In this context, the debates and choices around the Laguna alternate without a unified design. Venice is always less connected with the surroundings by water, and the water itself become a limit to mobility, where, on the contrary, it was the element that guaranteed it.In the renewed debate on development strategies, realized the MOSE, it will be asked for which city it has been made. The conference drew attention to the rediscovery of the central role of the Lagoon. Between local development and global challenges, including heritage and environmental protection. Is it possible to envisage a revitalization of the lagoon system as a matrix of physical and cultural connection? Which opportunities are offered today to the city of Venice to rediscover its amphibious and cosmopolitan size and discover the Laguna as an Eighth District? A place of sites for residence, recreation, work, in a renovated urban dimension across the board, opened towards the spaces of the islands.

The Sustainability of Mediterranean Port Areas: Environmental Management for Local Regeneration in Valencia

Full Text Available Urban renovation projects, which have led to the conversion of port areas through a new vision of waterfronts as elements of the potential development of the urban system in its entirety, have spread since the early 1950s and now some port cities are able to trigger some mechanisms which, even if they are the result of some processes that have been activated for decades and which are still evolving, are able to amplify and to extend over time their generated positive impacts. These impacts also produce a system of relations in the context of the hinterland, attracted also by policies of economic, social, and cultural development. In the case of the city of Valencia, we have seen, in the last 50 years, a progressive spread of the urbanized area to the coasts, simultaneously with a process of renovation of the port area, which has been populated by important architectures, and which has been equipped by efficient infrastructures and subjected to numerous recovery and restoration operations of its historic buildings. However, the environmental conditions near the port area are not well suited to a good quality of life because ports are pollution producers, sites of urban decay, and of social degradation. A good plan can include some instruments to decrease those negative factors, leading to a close merging between the port area and the city hinterland, and generating new economies. The proposal of this research consists in a method of integrating the port planning with an environmental accounting system.

Simulation of the effects of proposed tide gates on circulation, flushing, and water quality in residential canals, Cape Coral Florida

Goodwin, Carl R.

1991-01-01

Decades of dredging and filling of Florida's low-lying coastal wetlands have produced thousands of miles of residential tidal canals and adjacent waterfront property. Typically, these canals are poorly flushed, and over time, accumulated organic-rich bottom materials, contribute to an increasingly severe degraded water quality. One-dimensional hydrodynamic and constituent-transport models were applied to two dead-end canal systems to determine the effects of canal system interconnection using tide gates on water circulation and constituent flushing. The model simulates existing and possible future circulation and flushing conditions in about 29 miles of the approximately 130 miles of tidally influenced canals in Cape Coral, located on the central west coast of peninsular Florida. Model results indicate that tidal water-level differences between the two canal systems can be converted to kinetic energy, in the form of increased water circulation, but the use of one-way tide gate interconnections. Computations show that construction of from one to four tide gates will cause replacement of a volume of water equivalent to the total volume of canals in both systems in 15 to 9 days, respectively. Because some canals flush faster than others, 47 and 21 percent of the original canal water will remain in both systems 50 days after start of operation of one and four tide gates, respectively. Some of the effects that such increased flushing are expected to have include reduced density stratification and associated dissolved-oxygen depletion in canal bottom waters, increased localized reaeration, and more efficient discharge of stormwater runoff entering the canals.

Seasonal distribution and interactions between plankton and microplastics in a tropical estuary

Lima, A. R. A.; Barletta, M.; Costa, M. F.

2015-11-01

The seasonal migration of a salt wedge and rainfall were the major factors influencing the spatiotemporal distribution of ichthyoplankton and microplastics along the main channel of the Goiana Estuary, NE Brazil. The most abundant taxa were the clupeids Rhinosardinia bahiensis and Harengula clupeola, followed by the achirid Trinectes maculatus (78.7% of the catch). Estuarine and mangrove larvae (e.g. Anchovia clupeoides, Gobionellus oceanicus), as well as microplastics were ubiquitous. During drier months, the salt wedge reaches the upper estuary and marine larvae (e.g. Cynoscion acoupa) migrated upstream until the zones of coastal waters influence. However, the meeting of waterfronts in the middle estuary forms a barrier that retains the microplastics in the upper and lower estuary most part of the year. During the late dry season, a bloom of zooplankton was followed by a bloom of fish larvae (12.74 ind. 100 m-3) and fish eggs (14.65 ind. 100 m-3) at the lower estuary. During the late rainy season, the high freshwater inflow flushed microplastics, together with the biota, seaward. During this season, a microplastic maximum (14 items 100 m-3) was observed, followed by fish larvae maximum (14.23 ind. 100 m-3) in the lower estuary. In contrast to fish larvae, microplastics presented positive correlation with high rainfall rates, being more strictly associated to flushing out/into the estuary than to seasonal variation in environmental variables. Microplastics represented half of fish larvae density. Comparable densities in the water column increase the chances of interaction between microplastics and fish larvae, including the ingestion of smaller fragments, whose shape and colour are similar to zooplankton prey.

TRIESTE AND ITS PORT AS PARADIGM OF A RENEWED SEA-ORIENTED VISION?

Full Text Available Historically, the identity of the coastal cities is closely linked to the complex relationship with the sea, a primary resource for the origin of the processes of economic growth and territorial transformation, with particular reference to the highly-sensitive border between earth and water, and their dynamics.Dynamics more and more complex in the light  of the issues related to sustainable development, and to EU policies in the field of multimodal transport.In particular, the current guidelines and directives of the EU, the geopolitical changes of the past two decades in an enlarged and projected onto the East and the Mediterranean are favorable conditions for the city of Trieste, able to reacquire a new centrality in the context Euro-Mediterranean as port of a broader territorial system, where the waterfront can be an opportunity to promote a new urban quality and revitalize local identities against the risks of uniformity.These themes must be tackled at the different territorial and institutional levels, in a perspective of governance that implies an increasing participation of different local public and private actors in planning shared scenarios and looking for a delicate equilibrium between local and global dimensions.The need to include the single projects of transformation in a shared strategic vision, the capacity to elaborate an innovative management of plans, projects and partnerships with a strong local character and the decisive importance of time, as a crucial variable in a rapidly evolving context, must be driving forces behind the development of Trieste, so that it can be projected into the future with a new Euro- Mediterranean role, without forgetting the problems connected to sustainability.

Use of a risk-based hydrogeologic model to set remedial goals in a Puget Sound basin watershed

Pascoe, G.; Gould, L.; Martin, J.; Riley, M.; Floyd, T.

1995-01-01

The Port of Seattle is redeveloping industrial land for a container terminal along the southwest Seattle waterfront. Concrete, asphalt, ballast, and a landfill geomembrane will cover the site and prevent direct contact with surface soils, so remedial goals focused on groundwater contamination from subsurface soils. Groundwater at the site flows along an old stormwater drain, in a filled estuary of a small creek, to Elliott Bay. Remedial goals for a variety of organic chemicals, metals, and TPH in subsurface soils were identified to protect marine receptors in the bay and their consumers. Washington State and federal marine water quality criteria were the starting points in the risk-based model, and corresponding concentrations of chemicals in groundwater were back-calculated through a hydrogeologic model. The hydrogeologic model included a mixing zone component in the bay and dilution/attenuation factors along the groundwater transport pathway that were determined from onsite groundwater and surface water chemical concentrations. A rearranged Summers equation was then applied in a second back-calculation to determine subsurface soil concentrations corresponding to the back calculated groundwater concentrations. The equation was based on calculated aquifer flow rates for the small creek watershed and rates of infiltration through surface materials calculated for each redevelopment soil cover type by the HELP model. Results of the risk-based hydrogeologic back-calculation model indicate that, depending on soil cover type at the site, concentrations in subsurface soils of PCBs from 2 to 1,000 mg/kg and of TPH up to free phase concentration would not result in risks to marine organisms or their consumers in Elliott Bay

Na-smectite s in the Cala de Tomate bentonite deposit (Spain): a natural analogue of the salinity effect on the bentonite barrier of a rad waste disposal

Within the framework of the ENRESA programme for the assessment of the long-term behaviour of the bentonite-engineered barrier for a deep radwaste geological repository, analogue studies on several bentonite deposits are conducted at CIEMAT. Among these analogue studies, the thermal effect induced by volcanic intrusions on bentonite deposits is highlighted. In the Cabo de Gata volcanic region, there are several analogue scenarios where these studies have been performed, such as the Cala de Tomate bentonite deposit that was intruded by a pyroxene andesite volcanic dome. However, geological, mineralogical, physicochemical, geochemical and stable isotopic data obtained from the smectites do not allow to establish any analogy with the thermal effect expected on the bentonite-engineered barrier of a deep geological repository after burial. Thus, the bentonitisation processes took place after the intrusion of the dome, as a result of meteoric diagenesis intensively developed on faulting zone affecting the parent pyroclastic acid tuffs. This faulting process occurred after the dome intrusion. However, the physicochemical characteristics of these smectites, specially the exchangeable cations, allow to consider this bentonite deposit as a natural analogue of the saline effect on the clayey barrier. This analogy has been established because Na-smectites are present in this deposit and, up to our present knowledge, it is the first time that these smectites occur naturally in the Cabo de Gata-La Serrata de Nijar volcanic region. As a consequence, the main objectives of this work are: i) to characterise these smectites; ii) to establish their genesis and processes affecting them after their formation and iii) to identify the effects on the bentonite-engineered barrier should it were affected by a Na-rich saline waterfront.

Historiography on Japan’s place within the world of maritime Asia has undergone dramatic reinterpretation in recent decades. Scholars of the early modern era have thoroughly demolished the shibboleth of sakoku (“closed country”, the supposed isolation of Tokugawa Japan before the sudden arrival of Western gunboats in the 1850s. The active pursuit of diplomatic and commercial ties by shogun and daimyo alike embedded Japan firmly within global circuits of exchange (e.g., Hellyer 2010; Toby 1984. Scholars of the modern era, for their part, have been inspired by the “imperial turn” to put overseas empires at the heart of national narratives. Bookending the Tokugawa and Meiji periods, the two studies under review here push the frontiers of this research agenda further. Noell Wilson’s political history focuses on the buildup of domainal defense on the coast and the devolution of shogunal monopoly on violence. At the heart of this dialectical relationship was the “Nagasaki system”—the security arrangements that originated in the eponymous port and were eventually implemented throughout Japan. Catherine Phipps’s economic history examines the commercial expansion of Meiji Japan by tracing maritime networks of exchange, transportation, and information at multiple spatial scales. Forged in the crucible of Western imperialism, such ties simultaneously compromised the sovereignty of the nation while laying the foundations for empire.

Haptic and Olfactory Experiences of the Perth Foreshore: Case Studies in Sensory History

Directory of Open Access Journals (Sweden)

Saren Reid

2015-11-01

Full Text Available The liminal zone where a city meets ‘the water’s edge’ is a place of heightened sensory experiences. In Australia, these settings have been continually reshaped and experienced, individually and collectively, both before and after European settlement, and so they provide a physical domain for reinterpreting Australian history. In Perth, Western Australia, at the turn of the twentieth century, two recreational buildings on the foreshore, the Perth City Baths (1898–1914 and the Water Chute (1905–unknown, promoted new aquatic leisure practices that provided heightened sensory experiences of the Swan River and the city foreshore. These buildings are examined from the perspective of ‘sensory history’, an alternative form of cultural and environmental analysis that has been garnering interest from a range of disciplines over the past several decades (see, for example, the work of Constance Classen, Alain Corbin, David Howes and Mark M Smith. Sensory history seeks to reveal through historical inquiry the informative and exploratory nature of the senses in specific contexts. The potential value of sensory history to studies of built and natural environments lies in drawing attention away from the overweening and frequently generalising dominance of ‘the visual’ as a critical category in humanities research. The case studies explore how evolving swimming practices at the City Baths and ‘shooting the chutes’ at the Water Chute provided novel, exciting and sometimes unpleasant haptic and olfactory experiences and consider how changing forms of recreation allowed for broadly sensuous rather than primarily visual experiences of the foreshore and Swan River. These case studies are part of a larger body of research that seeks to ‘make sense’ of the Perth foreshore and, more broadly, Australian urban waterfronts as sites of varied and evolving sensory experience.

Variations in population vulnerability to tectonic and landslide-related tsunami hazards in Alaska

Wood, Nathan J.; Peters, Jeff

2015-01-01

Effective tsunami risk reduction requires an understanding of how at-risk populations are specifically vulnerable to tsunami threats. Vulnerability assessments primarily have been based on single hazard zones, even though a coastal community may be threatened by multiple tsunami sources that vary locally in terms of inundation extents and wave arrival times. We use the Alaskan coastal communities of Cordova, Kodiak, Seward, Valdez, and Whittier (USA), as a case study to explore population vulnerability to multiple tsunami threats. We use anisotropic pedestrian evacuation models to assess variations in population exposure as a function of travel time out of hazard zones associated with tectonic and landslide-related tsunamis (based on scenarios similar to the 1964 M w9.2 Good Friday earthquake and tsunami disaster). Results demonstrate that there are thousands of residents, employees, and business customers in tsunami hazard zones associated with tectonically generated waves, but that at-risk individuals will likely have sufficient time to evacuate to high ground before waves are estimated to arrive 30–60 min after generation. Tsunami hazard zones associated with submarine landslides initiated by a subduction zone earthquake are smaller and contain fewer people, but many at-risk individuals may not have enough time to evacuate as waves are estimated to arrive in 1–2 min and evacuations may need to occur during earthquake ground shaking. For all hazard zones, employees and customers at businesses far outnumber residents at their homes and evacuation travel times are highest on docks and along waterfronts. Results suggest that population vulnerability studies related to tsunami hazards should recognize non-residential populations and differences in wave arrival times if emergency managers are to develop realistic preparedness and outreach efforts.

The Ganges and the GAP: An Assessment of Efforts to Clean a Sacred River

Directory of Open Access Journals (Sweden)

Kenneth R. Tamminga

2012-07-01

Full Text Available For centuries, the Ganges River in India has been the locus of sacred rites for the Hindus. The religious significance of the Ganges is physically manifested in ghats (stepped landings that form the land-water interface. Besides serving as a site for religious bathing and cremation, the ghats are also tied to people’s livelihoods and are an inseparable part of their daily lives. Today, the increasingly urbanized Ganges basin sustains more than 40 percent of India’s population. At the same time, industrialization and the pressures of a growing population along its banks have contributed to alarming levels of pollution in the river. In 1985, the federal government of India launched the Ganga Action Plan (GAP with the primary objective of cleaning the river. However, characterized by centralized planning and control with little public participation, the GAP had limited impact. In 2011, the government launched yet another clean up program—the National Ganga River Basin Project—with support from the World Bank. In this paper, we take a closer look at the programs to highlight the tenuous relationship between the need for ‘efficient’ management of environmental problems and public participation. Can public participation fit into the technocratic model that is often adopted by environmental programs? What approaches to participation kindle authorship and empowerment among those who share a deep relationship with the river and the ghats? Can religious practices be accommodated within scientific frameworks of adaptive management and resilience? We argue that rethinking the relationship between pollution control programs and participation is crucial for any effort to clean the Ganges, restore its waterfront, and catalyze broader regeneration in the Ganges basin.

Deformation analysis and prediction of bank protection structure with river level fluctuations

Hu, Rui; Xing, Yixuan

Bank structure is an important barrier to maintain the safety of the embankment. The deformation of bank protection structure is not only affected by soil pressure caused by the excavation of the riverway, but also by the water pressure caused river water level fluctuations. Thus, it is necessary to establish a coupled soil-water model to analyze the deformation of bank structure. Based on Druck-Prager failure criteria and groundwater seepage theory, a numerical model of bank protection structure with consideration of the pore water pressure of soil mass is established. According to the measured river level data with seasonal fluctuating, numerical analysis of the deformation of bank protection structure is implemented. The simulation results show that the river water level fluctuation has clear influence on the maximum lateral displacement of the pile. Meanwhile, the distribution of plastic zone is related to the depth of groundwater level. Finally, according to the river water level data of the recent ten years, we analyze the deformation of the bank structure under extreme river level. The result shows that, compared with the scenario of extreme high river level, the horizontal displacement of bank protection structure is larger (up to 65mm) under extreme low river level, which is a potential risk to the embankment.

Dredging up the past -- removal of historic low-level radioactive sediment from the Port Hope harbour

2011-01-01

Port Hope is located on the northern shore of Lake Ontario at the confluence of the Ganaraska River and has existed as a Port of Entry since at least 1819. Once operated as a major Lake Ontario port, through periods of vibrant industrial growth, it is now a recreational anchorage for the local yacht club. The history of the Port Hope harbour from the early 1800s to today is typical of other small-town ports along Lake Ontario that have experienced growth and decline in direct relation to Great Lake shipping volumes and the shift in industry and commerce to larger urban areas. However, in the case of the Port Hope harbour, the presence of low-level radioactive sediment, resulting from a former radium and uranium refinery that operated alongside the harbour, currently limits redevelopment and revitalization opportunities. The presence of low-level radioactive waste is not limited to only harbour sediments. Several other on-land locations within the community are also affected by the low-level radioactive waste management practices of the past. To address these situations, the Port Hope Area Initiative project is currently underway to implement a local, safe, long-term waste management solution. The Port Hope Area Initiative is a community initiated undertaking that will result in the consolidation of an estimated 1.2 million cubic metres of the low-level radioactive waste from the various sites in Port Hope into a new engineered above ground long-term waste management facility. The remedial cleanup of the estimated 120,000 cubic metres of contaminated sediments from the Port Hope harbour is one of the more challenging components of the Initiative. This paper demonstrates how the historical development of the harbour over the past 200 years, the nature and extent of the contaminated sediments, and Municipality of Port Hope’s desires for future redevelopment of the waterfront area have all played a role in the design of the remedial cleanup plan for the Port Hope

Full Text Available Anderson’s crocodile newt (Echinotriton andersoni is distributed in the Central Ryukyu Islands of southern Japan, but environmental degradation and illegal collection over the last several decades have devastated the local populations. It has therefore been listed as a class B1 endangered species in the IUCN Red List, indicating that it is at high risk of extinction in the wild. The species is also protected by law in both Okinawa and Kagoshima prefectures. An artificial insemination technique using hormonal injections could not be applied to the breeding of this species in the laboratory. In this study we naturally bred the species, and tested a laboratory farming technique using several male and female E. andersoni pairs collected from Okinawa, Amami, and Tokunoshima Islands and subsequently maintained in near-biotopic breeding cages. Among 378 eggs derived from 17 females, 319 (84.4% became normal tailbud embryos, 274 (72.5% hatched normally, 213 (56.3% metamorphosed normally, and 141 (37.3% became normal two-month-old newts; in addition, 77 one- to three-year-old Tokunoshima newts and 32 Amami larvae are currently still growing normally. Over the last five breeding seasons, eggs were laid in-cage on slopes near the waterfront. Larvae were raised in nets maintained in a temperature-controlled water bath at 20 °C and fed live Tubifex. Metamorphosed newts were transferred to plastic containers containing wet sponges kept in a temperature-controlled incubator at 22.5 °C and fed a cricket diet to promote healthy growth. This is the first published report of successfully propagating an endangered species by using breeding cages in a laboratory setting for captive breeding. Our findings on the natural breeding and raising of larvae and adults are useful in breeding this endangered species and can be applied to the preservation of other similarly wild and endangered species such as E. chinhaiensis.

Creating Student Engagement Through Immersion: Exploring the MT6 Shipwreck in Puget Sound via Submersible, Using a Team Challenge Format

Educational literature has many stories describing the "aha" moment that teachers are privileged to observe: a student who suddenly grasps a concept (ding!), dives into an activity (whee!) or works tirelessly to complete a complicated project (wow!). Designing moments like these for students can be one of the great joys of teaching. Experiencing such a moment can have a lasting impact on student engagement and motivation, and is the underlying rationale for the importance of creating a wide array of outreach efforts, from field work to telepresence activities.During the spring of 2015, OceanGate Foundation and Seattle Central College partnered on a pilot program to design a program that had this kind of impact and created the Open The Oceans Challenge. Student teams responded to our Request for Proposal (RFP), which was centered around the exploration of a shipwreck in 150 meters of water just off the Seattle waterfront, the MT-6. Students spent a significant amount of time crafting their proposals and reported that they enjoyed the process of writing the proposal as a team. The two winning teams accompanied us on a series of submersible dives performed by OceanGate, Inc. and worked up the results afterward. In addition to researching the MT-6 wreck and documenting what they found, students were able to do basic observational research on the wreck, providing sonar and photographic data that will help form the basis of future expeditions to this site.We report on lessons learned from this pilot — the impact for the small set of students involved in this project was profound, but how can we expand the reach of such activities? Results from this experience suggest that providing a highly engaging topic and expedition may not be enough to inspire an "aha" moment that creates lasting engagement; the scaffolding and mentorship that surrounds a rich experience is also critical.

In Kenya, infestations of Sonneratia alba have persisted for almost two decades, yet the taxonomic identity of the infesting pest(s, the extent of infestation, the pests' biology, the impacts of infestation on host and the ecosystem, the host's defensive strategies to the infestation are poorly understood. S. alba is a ubiquitous, pioneer mangrove species of the Indo-Pacific, occurring along the waterfront in a variety of mangrove ecosystem settings. Our main objectives were to identify the pest(s responsible for the current dieback of S. alba in Kenya, and to determine the extent of infestation. To identify the pests responsible for infestation, we trapped emergent insects and reared larvae in the laboratory. To determine the overall extent of infestation within the S. alba zone, we assessed nine sites along the entire Kenyan coastline for the presence or absence of infested mangroves. Insect infestation in two mangrove embayments (Gazi and Mida was quantified in depth. Two wood-boring insects were identified: a metarbelid moth (Lepidoptera, Cossoidea of undescribed genus and the beetle Bottegia rubra (Cerambycidae, Lamiinae.The metarbelid moth infests mangroves in both northern (from Ngomeni to Kiunga and southern regions (from Vanga to Mtwapa of the Kenyan coast. B. rubra appeared in low density in Gazi, and in high density in Mida, Kilifi, and Ngomeni, with densities gradually decreasing northward. Insect infestation levels reached 18% in Gazi and 25% of S. alba stands in Mida. Our results indicate that B. rubra has the ability to infest young mangrove trees and expand its range, posing a danger to rehabilitation efforts where plantations have been established. Thus, there is great need for forest managers to

A bloom of the harmful marine phytoplankton, Heterosigma carterae occurred in upper Case Inlet, south Puget Sound, Washington in late September, 1994, correlating with the presence of at least 35 dead salmon. This marks the first time that this alga has been closely correlated with a wild fish kill; in the past it was thought to be associated with kills of penned fish at fish farms only. We were informed of the presence of a possible harmful algal bloom and dead salinois Ilear the town of Allyn on 27 September and a team was formed to investigate. We arrived at the Allyn waterfront at 17:30 hours the same day. Prior to our arrival, state agency personnel walked approximatcly two miles of shoreline from the powerlines north of the dock, to the mouth of Sherwood Creek and conducted the only official count of dead fish present along the shore consisting of 12 coho salmon (Oncorhynchus kisutch), 11 chum salmon (Oncorhynchus keta), 12 chinook salmon (Oncorhynchus tschawytscha), one flat fish, and one sculpin on the morning of 9/27. Since previous harmful blooms of Heterosigma have resultedin the majority of net penreared salmon sinking to the bottom of pens, and only approximately two miles of shoreline were sampled, it is suspected that many more exposed fish may have succumbed than were counted. Witnesses who explored the east side of the bay reported seeing many dead salmon there as well, but no counts were made. State agency personnel who observed the fish kill reported seeing “dying fish coming to the beach, gulping at the surface, trying to get out of the water” Scavengers were seen consuming the salmon carcasses; these included two harbor seals, a house cat, and Hymenopteran insects. None suffered any noticeable acute ill effects. Although precise cause of death has not been ascertained, visual inspection of the reproductive organs from a deceased male chum salmon found on the shore at Allyn confirmed that the fish was not yet reproductively mature and

Since 2012 we have carried out extensive multibeam bathymetric and backscatter surveys in coastal waters of eastern Baffin Island, supplemented by sub-bottom imaging and coring. Shore-zone surveys have been undertaken in proximity to the communities of Iqaluit and Qikiqtarjuaq, following earlier work in Clyde River. These support benthic habitat mapping, geological exploration, analysis of past and present sea-level trends, and assessment of coastal hazards relating to climate change and seabed instability. Outputs include a seamless topographic-bathymetric digital elevation model (DEM) of extensive boulder-strewn tidal flats in the large tidal-range setting at Iqaluit, supporting analysis of coastal flooding, wave run-up, and sea-ice impacts on a rapidly developing urban waterfront in the context of climate change. Seabed mapping of inner Frobisher Bay seaward of Iqaluit reveals a potential local tsunami hazard in widespread submarine slope failures, the triggers, magnitudes, and ages of which are the subject of ongoing research. In fjords of the Cumberland Peninsula, this project has mapped numerous submerged delta terraces at 19 to 45 m present water depth. These attest to an early postglacial submerged shoreline, displaced by glacial-isostatic adjustment. It rises linearly over a distance of 100 km east to west, where a submerged boulder barricade on a -16 m shoreline was discovered at a proposed port site in Broughton Channel near Qikiqtarjuaq. Palaeotopographic mapping using the multibeam data revealed an enclosed estuarine environment quite different from the present-day open passage swept by tidal currents. At Clyde River, combined seabed and onshore DEMs with geohazard mapping provided foundation data for community assessment and planning under a local knowledge co-production initiative. The geohazard work identified portions of the town-site more vulnerable to both coastal flooding and potential thaw subsidence, while the shallow delta terrace suggested a

"Managed Retreat" in Response to Superstorm Sandy: The Oakwood Beach Story

Tirone, J.

2017-12-01

This presentation shares lessons learned from firsthand experience of the home buyout process in New York City after Superstorm Sandy. Many have described Sandy as "the perfect storm" from a meteorological perspective, but it was also the perfect storm from a government-buyout perspective. For a buyout to work in New York City, with its high property values and dense housing and population, many conditions had to be in place before the storm. Before Sandy hit, Oakwood Beach on Staten Island had already had enough. Hurricane Isaac flooded streets and basements in 2010, followed by Hurricane Irene in 2011. Many residents of this multi-generational neighborhood had just finished fixing their homes. A few years before, a brush fire spread through the invasive and highly flammable Phragmites reeds, destroying a protective berm installed by the Army Corps of Engineers in 2000 and threatening to damage many homes. An aerial view would show how these homes incredulously sat in the middle of a marsh, a marsh designated as part of the Bluebelt wetlands storm water management system by New York City's Department of Environmental Protection. Even more incredulously, while New York City was buying up unimproved lots to expand the Bluebelt to improve drainage for inland homes, the City was also issuing building permits to developers - sometimes for lots directly in the Bluebelt's path. Welcome to Staten Island, where the political influence of developers made any effort to retreat from the waterfront especially difficult and contentious. Before the storm, no one knew what a buyout was, never mind how to go about seeking one. For the most part, this included local officials. Managed retreat is typically understood as a top-down directive, but in this case the buyout plan was initiated from the bottom up by eight ordinary citizens who used research, trust, and networking to get their voices heard and, against all odds, to drive a highly successful State-supported buyout program.

Large scale flooding of waterfront neighborhoods occurred in New York City (NYC) during Superstorm Sandy. While NYC waterways commonly experience combined sewer overflow (CSO) and associated water quality degradation during rain storms, Superstorm Sandy was unique in that these potentially contaminated waters were transported over the banks and into city streets and buildings. Sampling of waterways, storm debris on city streets, and flood water trapped in building basements occurred in the days following Sandy, including in neighborhoods bordering the Gowanus Canal and Newtown Creek, which are both Superfund sites known to frequently contain high levels of sewage associated bacteria and metal contamination. Samples enumerated for the sewage indicating bacterium, Enterococcus, suggest that well-flushed waterways recovered quickly from sewage contamination in the days following the storm, with Enterococci concentrations similar to background levels measured before flooding occurred. In contrast, storm debris on city streets and waters from flooded basements had much higher levels of sewage-associated bacteria days after flooding occurred. Analysis of 180,000 bacterial 16S rRNA gene sequences obtained from flood water samples and flood debris confirmed the presence of bacterial genera often associated with sewage impacted samples (e.g. Escherichia, Streptococcus, Clostridium, Trichococcus, Aeromonas) and a community composition similar to CSO discharge. Elemental analysis suggests low levels of metal contamination in most flood water, but much higher levels of Cu, Pb, and Cr were found in leach from some storm debris samples found adjacent to the Newtown Creek and Gowanus Canal superfund sites. These data suggest a rapid recovery of water quality in local waterways after Superstorm Sandy, but that trapped flood water and debris samples in urban neighborhoods retained elevated levels of microbial sewage pollution, and in some cases metal pollution, days after that

The Exploratorium engages Americans on issues of climate change, and energy use and production in a distinctive way; using a multilayered approach emphasizing all of the Exploratorium's strengths, not simply exhibitions. Specifically, the institution gives people access to the latest science research and researchers, provides the inquiry skills and basic science needed to make sense of this research, studies perception and cognition and how we come to believe what we believe, and sets up social communities and spaces for people to test their ideas and understandings with others. Using exhibits, the web and other media, visualization technology, building architecture, physical spaces, classes and professional education the Exploratorium achieves this multilayered approach. This powerful combination enhances people's own ability to make sound, evidence-based decisions for themselves, their families, and their communities. In 2013, the Exploratorium will move from its current home in the Palace of Fine Arts in San Francisco to a waterfront campus with access to the bay and outdoor platforms for instrumentation and observation. This will allow program and exhibit development in the environmental sciences that focuses on natural phenomena and physical and biological systems. Some current and planned Exploratorium projects with an emphasis on global climate change and potential for further development in the new location: 1. An Observatory building, where visitors can investigate Bay waters and climate. 2. Wired Pier, a suite of environmental sensors that will track local conditions over time and connect to larger observing networks regionally and globally 3. NOAA education and climate science partnership, including a scientist-in-residence program for training front-line staff 4. Global Climate Change Research Explorer website enabling visitors to observe current climate data or analyze evidence. 5. The Ice Stories project which trained polar scientists in media

Husbandry and Sustainability of Water Buffaloes in Turkey

Directory of Open Access Journals (Sweden)

Orhan Ermetin

2017-12-01

Full Text Available Water buffaloes in Turkey originate from Mediterranean Water Buffaloes, a subgroup of river water buffaloes and are known as Anatolian Water Buffalo. During the 1970’s the number of water buffaloes in Turkey was one million, but in 2010 this figure dropped to about 85.000. Thanks to the incentives introduced for water buffalo husbandry in recent years, the water buffalo population has risen to 143.073 heads. Water buffalo husbandry in Turkey is performed in some provinces of the Black Sea, Marmara and Central Anatolian Regions. The provinces with the highest amount of water buffalo existence are listed as Samsun, Diyarbakır, Istanbul, Tokat, Bitlis, Muş, Afyon, Kayseri, Sivas and Amasya. Breeding style in Turkey is in the form small family business, with an average of 1-5 animals per enterprise. Family enterprises are keeping water buffaloes for their own consumption. Mostly breeding in modern enterprises formed for indoor barn breeding, the size of the herds is around 50 to 100 heads. Being done only at swamps or waterfronts in the past, water buffalo husbandry increasingly takes place in modern facilities nowadays. The colour of Anatolian Water Buffaloes is generally black and their horns curved backwards, are called arch horns in Turkey. The lactation milk yield and lactation length in Anatolian Water Buffaloes are between 800 and 1100 kg and about 180-280 days respectively. It is demonstrated that they varied according to effects of environmental factors, care and feeding. Adult water buffalo’s live weight is about 411-518 kg. The first insemination age of water buffalo is 32 to 43 months and during a lifespan the number of lactation periods is 5 to 10. For adult water buffalo at withers the height of females is being expressed as around 135 cm. Calves are generally breastfed for 3-4 months. Generally, water buffaloes are milked twice a day in the village farms by hand.

Combined sewer overflows impact on water quality and environmental ecosystem in the Harlem River

Wang, J.

2017-12-01

Combined sewer overflows (CSOs) discharge untreated sewage into the Harlem River during wet weather conditions, and it elevated nutrients and pathogen levels. It is not safe for swimming, fishing or boating especially in rainstorms. The Harlem River, a 9.3 mile long natural straight, connects the Hudson and East Rivers in New York City. It had been historically used for swimming, fishing, boating. Anthropogenic impacts have degraded water quality, limiting current aquatic activity in the river. CSOs water samples were collected during rainstorms, and analyzed in the laboratories of the Chemistry and Biology Department, Bronx Community College, City University of New York. Results showed elevated bacteria/pathogen and nutrient levels. Most recent data showed an ammonia concentration of 2.6 mg/L on July 30, 2015 during a heavy afternoon thunderstorm, and an ammonia level 2.7mg/L during tropical storm Arthur on July 2, 2014. Both significantly exceeded the EPA regulation level for NYC waters of 0.23mg/L. Phosphate levels peaked at 0.197 mg/L during a heavy thunderstorm on Apr 28, 2011, which was much higher than regulated level of 0.033 mg/L. Turbidity was 319 FAU during the July 30 2015 heavy thunderstorm, and was 882 FAU during tropical storm Arthur; which was significantly higher than regulation level of 5.25 FAU. CSOs collected during a recent heavy rainstorm on Oct 28, 2015, showed fecal coliform of 1 million MPN/100ml, E.Coli. of 60,000 MPN/100ml, and enterococcus of 65,000 MPN/100ml; which exceeded regulated levels of fecal coliform-200 MPN/100ml, E.Coli.-126 MPN/100ml, enterococcus-104 MPN/100ml. It is critical to reduce CSOs, restore ecosystem and improve water quality of the Harlem River. Green wall, green roof, and wetland had been used to reduce stormwater runoff & CSOs in the Bronx River; these green infrastructures are going to be used along the Harlem River waterfront as well. The goal of this research is to make the Harlem River swimmable and fishable

Improvements in Hudson River Water Quality Create the Need for a new Approach to Monitoring and Management

The lower Hudson River is a well-flushed temperate estuary that continues to support diverse wildlife populations although its shores are home to the nation's most populated metropolitan area. Data sets from the last hundred years clearly demonstrate extreme nutrient concentrations, pathogen loading, and periods of persistent hypoxia. These data also show a clear trend of steadily improving water quality in the last thirty years. Recent increases in recreational activity, expanded shoreline parks, and waterfront redevelopment, indicate the return of the people of New York to the River, concomitant with improved water quality. While mean seasonal water quality indicators are now often acceptable for large portions of the River, there remains a lack of information about the finer scale spatial and temporal variability of water quality. A new water quality sampling program was initiated in the Fall of 2006 to address this challenge. Monthly sampling cruises collected continuous underway surface measurements of hydrographic variables in parallel with discrete sampling for nutrients and microbiology. In general, these data indicate that mid-channel locations are often within acceptable water quality standards during dry weather, but that wet weather events deliver large quantities of sewage to the River, leading to short-term deterioration in water quality. In 2006-2007, only 6 of 27 sample sites had geometric mean values for Enterococcus , a sewage-indicating microorganism, that suggest consistently poor water quality. In contrast, single-day exceedances of EPA recommended guidelines for Enterococcus were found at 21 of the 27 sites. Although the mid-channel of the River was relatively homogenous with respect to sewage indicators, large changes were observed at tributary mixing interfaces and along the shallow edges of the River where human contact is most likely. The changing use of the River, together with new information about the importance of episodic and

SHARJAH’S ISLAMIC URBAN IDENTITY AND THE LIVING CITY

Full Text Available Prominently placed amidst open gardens and along the waterfront of the Sharjah Corniche,  several recent monumental buildings collectively suggest a new urban image and socio-cultural space for a modern Muslim urban identity. Along with a series of restaurants, entertainment spaces, and office building, Masjid al-Noor, Masjid al-Maghfira, Al-Qasbah, and the Museum of  Islamic Civilization house important cultural institutions, combining eclectic references to the history of Islam into a new urban order. Neither entirely the conservative vernacularism of whole-scale historical mimicry, nor altogether the neo-vernacularism of fragmentary pastiche, this urban assemblage embraces these two distinct design approaches at the level of the individual buildings, but unifies them at the urban scale in what could be called neo-regional urbanism.  The stylistic clarity of Masjid al-Noor, which consistently integrates the stylistic elements of Ottoman styled mosques, contrasts with the isolated fragments of Moorish/Hispanic lattice work that adorn the otherwise modern Masjid al-Maghfira. Al-Qasbah’s neo-Islamic horse-shoe arches contrast with the Syrian-Ottoman styled facades of the Museum of Islamic  Civilization.  Although  these  buildings  individually  address  the  problems  of  built  form  and  the application of Islamic ornaments disparate ways, taken together this group of new monuments forms a complex urban whole that serves to reflect and deepen an emerging sense of identity that is built upon  a similarly complex mix of multicultural non-western ethnicities that make up the fluid and mobile population of Sharjah. This urban assemblage has become such a popular space of gathering that it has begun to shift the centre of gravity of Sharjah’s urban social space towards the Corniche,  and in so doing has produced an authentic alternative to the introverted malls and isolated dreamscapes of Dubai.

The social connectivity of urban rivers

Science.gov (United States)

Kondolf, G. Mathias; Pinto, Pedro J.

2017-01-01

By social connectivity we refer to the communication and movement of people, goods, ideas, and culture along and across rivers, recognizing longitudinal, lateral, and vertical connectivity, much as has been described for other rivers for hydrology and ecology. We focus on rivers as they pass through cities, and the relationships between these rivers and city dwellers. Historically, the most important longitudinal connectivity function of rivers was their role as major transport routes and the simplification of formerly complex, irregular banks and beds, into straight, uniform shipping channels has resulted in a loss of lateral and vertical connectivity, notably the quotidian uses such as fishing, washing clothes, water supply, swimming and other recreation. The scale of the river itself, and its scale in comparison to the scale of the city, largely determine the river's social function and the degree to which it influences city form. River width affects the perception of 'closeness' of the other bank, ease of bridging the river, influence of the river on the city's street pattern, and type of waterfront uses that occur. Up to 15 m wide, people can converse, whereas across rivers 50 to 200 m wide, people are not recognizable but still clearly visible, instilling the banks with a 'lively' atmosphere. At widths over 200 m, people blur, yet moving vehicles and trees branches shaking in wind may still provide some dynamic elements to an otherwise static landscape composed of building facades. In exceptionally wide rivers, the city on the opposite bank is little more than a skyline, which often becomes a signature and symbol of regional identity. In contemplating how people use rivers, we can define a range of human activities in relation to height above the water (i.e., instream to banktop), a vertical dimension of human connectivity with rivers. Many uses occur on the top of the bank, such as quiet contemplation, walking, or cycling along a riverside trail, while

We need to go further, allowing the city to demolish definitely the port barriers which still deprive it of the fruition of its sea, acting consistently with the intervention designed and implemented by Hippodamus of Miletus in Athens during the Age of Pericles, so that the city could join its port (Piraeus, thought with some mediation: a protective wall which would sanction a right of reciprocal belonging, physically and institutionally, between the city and the sea.

Urban Landscape Architecture in the Reshaping of the Contemporary Cityscape

Ananiadou-Tzimopoulou, Maria; Bourlidou, Anastasia

2017-10-01

The contemporary urban landscape is the evolving image of dynamic social, economic and ecological changes and heterogeneity. It constitutes the mirror of history, natural and cultural, urban processes, as well as locations of hybrid character, such as degraded and fragmented spaces within the urban fabric or in the city boundaries -areas in between, infrastructures, post-industrial and waterfront sites, but also potential grounds for urban development. Along with the awakening of the global ecological awareness and the ongoing discussion on sustainability issues, the cityscape with its new attributes, constitutes a challenging field of research and planning for various disciplines, further more than landscape architecture, such as architecture, planning, ecology, environment and engineering. This paper focuses on the role of urban landscape architecture, via its theory and practice, in the reshaping of the city territory. It aspires to broaden the discussion concerning the upgrading of the contemporary cities, aiming firstly at the determination of a wider vocabulary for the urban landscape and its design, and secondly at the highlighting of landscape architecture’s contribution to the sustainable perspective of urban design and planning. The methodology is based on a comparative research implemented both on a theoretical level and on a level of applied work. Urban landscape architecture is described through theory and practice, along with correlative approaches deriving mainly from landscape urbanism and secondarily from the field of architecture. Urban landscape is approached as a socio-ecological and perceptual legible, a territory of culture, process and production; operating as an entity of ecological, infrastructural systems and planning needs, it is also regarded as a precedent for urban development. Furthermore, the research is supported by selected European and International urban landscape projects, presented in a cohesive multiscalar approach, from the

There is a continued need to understand how human activities along the northern Gulf of Mexico coast are impacting the natural ecosystems. The gulf coast is experiencing rapid population growth and associated land cover/land use change. Mobile Bay, AL is a designated pilot region of the Gulf of Mexico Alliance (GOMA) and is the focus area of many current NASA and NOAA studies, for example. This is a critical region, both ecologically and economically to the entire United States because it has the fourth largest freshwater inflow in the continental USA, is a vital nursery habitat for commercially and recreational important fisheries, and houses a working waterfront and port that is expanding. Watershed and hydrodynamic modeling has been performed for Mobile Bay to evaluate the impact of land use change in Mobile and Baldwin counties on the aquatic ecosystem. Watershed modeling using the Loading Simulation Package in C++ (LSPC) was performed for all watersheds contiguous to Mobile Bay for land use Scenarios in 1948, 1992, 2001, and 2030. The Prescott Spatial Growth Model was used to project the 2030 land use scenario based on observed trends. All land use scenarios were developed to a common land classification system developed by merging the 1992 and 2001 National Land Cover Data (NLCD). The LSPC model output provides changes in flow, temperature, sediments and general water quality for 22 discharge points into the Bay. These results were inputted in the Environmental Fluid Dynamics Computer Code (EFDC) hydrodynamic model to generate data on changes in temperature, salinity, and sediment concentrations on a grid with four vertical profiles throughout the Bay s aquatic ecosystems. The models were calibrated using in-situ data collected at sampling stations in and around Mobile bay. This phase of the project has focused on sediment modeling because of its significant influence on light attenuation which is a critical factor in the health of submerged aquatic

Examining the economic impacts of hydropower dams on property values using GIS.

While the era of dam building is largely over in the United States, globally dams are still being proposed and constructed. The articles in this special issue consider many aspects and impacts of dams around the world. This paper examines dam removal and the measurement of the impacts of dams on local community property values. Valuable lessons may be found. In the United States, hundreds of small hydropower dams will come up for relicensing in the coming decade. Whether or not the licenses are renewed and what happens to the dams if the licenses expires is a subject of great debate. Dams are beginning to be removed for river restoration and fisheries restoration and these "end-of-life" decisions may offer lessons for countries proposing or currently building small (and large) hydropower dams. What can these restoration stories tell us? In this paper, we examine the effects of dams along the Penobscot River in Maine (USA) on residential property values. We compare the results to findings from a similar (but ex post dam removal) data set for properties along the Kennebec river in Maine, where the Edwards Dam was removed in 1999. The Penobscot River Restoration Project, an ambitious basin-wide restoration effort, includes plans to remove two dams and decommission a third along the Penobscot River. Dam removal has significant effects on the local environment, and it is reasonable to anticipate that environmental changes will themselves be reflected in changes in property values. Here we examine historical real estate transaction data to examine whether landowners pay a premium or penalty to live near the Penobscot River or near a hydropower generating dam. We find that waterfront landowners on the Penobscot or other water bodies in our study area pay approximately a 16% premium for the privilege of living on the water. Nevertheless, landowners pay LESS to live near the Penobscot River than they do to live further away, contrary to the expectation that bodies of water

have delivered climate science in a variety of ways, each designed to connect the participants with a fundamental science concept while building excitement for the topic and facilitating learning in a non-traditional setting. Our approaches range from launching teams of young people into experiments exploring glacial physics through free-choice inquiry opportunities, to enlisting undergraduate science students in working with the participants demonstrating glacial motion and measurement through engaging technology such as Kinect Xbox 360 sensors, to short single concept hands-on activities designed to deliver a specific climate 'take home' message. (3) Generating a local connection to climate science and impacts: Working with local informal education groups we connect climate topics to community-based issues and 'hot topics' such as sustainable planning, waterfront erosion, storm surge impacts, and local sea level rise projections. Partnering with community based informal education providers allows us to expand our offerings to reach a wider audience of young people, and to connect more directly with our local community. We are excited by the potential in these partnerships to connect students with climate science and develop not only a climate literate group of young people, but also lifelong science learners.

Remediation of Centre Pier, Port Hope, Ontario: Historical, Logistical, Regulatory and Technical Challenges - 13118

Centre Pier is a 3.9 ha property owned by the Commissioners of the Port Hope Harbour in the Municipality of Port Hope, Ontario, Canada. It is centrally located on the Port Hope waterfront and is bounded on the west by the Port Hope Harbour, on the east by the Ganaraska River, on the south by Lake Ontario, and on the north by a railway corridor. The property is currently leased by the Commissioners of the Port Hope Harbour to the Cameco Corporation which owns the four onsite building that are used as warehouse space for their uranium conversion facility located on the western side of the Harbour. Remediation of this site forms part of the Port Hope Project being undertaken by Atomic Energy of Canada Limited (AECL) and Public Works and Government Services Canada (PWGSC) as part of the Port Hope Area Initiative (PHAI). Soil impacts include radiological, metals and petroleum hydrocarbons resulting from long term historical industrial use. Radiological impacts in soil extend across most of the site primarily within the upper metre of fill. Metals-contaminated soil is present across the entire site in the underlying fill material. The metals-contaminated fill extends to a maximum depth of 2.0 m below grade at the north end of the site which is underlain by peat. However, the metals-contaminated soil could extend to the top of the bedrock on the remainder of the site. Based on the elevation of the bedrock in the adjacent river and Harbour Basin, the metals-contaminated soil may extend to a depth of 5.6 m or 6.5 m below existing grade. Petroleum-contaminated soil is present on the southeast side of the site, where a storage tank farm was previously located. Challenges include: - The complex history of the site both relating to site use and Pier construction. Pier development began in the 1800's and was undertaken by many different entities. Modifications and repairs were made over the years resulting in several different types of Pier walls and fill that must be considered

Centre Pier is a 3.9 ha property owned by the Commissioners of the Port Hope Harbour in the Municipality of Port Hope, Ontario, Canada. It is centrally located on the Port Hope waterfront and is bounded on the west by the Port Hope Harbour, on the east by the Ganaraska River, on the south by Lake Ontario, and on the north by a railway corridor. The property is currently leased by the Commissioners of the Port Hope Harbour to the Cameco Corporation which owns the four onsite building that are used as warehouse space for their uranium conversion facility located on the western side of the Harbour. Remediation of this site forms part of the Port Hope Project being undertaken by Atomic Energy of Canada Limited (AECL) and Public Works and Government Services Canada (PWGSC) as part of the Port Hope Area Initiative (PHAI). Soil impacts include radiological, metals and petroleum hydrocarbons resulting from long term historical industrial use. Radiological impacts in soil extend across most of the site primarily within the upper metre of fill. Metals-contaminated soil is present across the entire site in the underlying fill material. The metals-contaminated fill extends to a maximum depth of 2.0 m below grade at the north end of the site which is underlain by peat. However, the metals-contaminated soil could extend to the top of the bedrock on the remainder of the site. Based on the elevation of the bedrock in the adjacent river and Harbour Basin, the metals-contaminated soil may extend to a depth of 5.6 m or 6.5 m below existing grade. Petroleum-contaminated soil is present on the southeast side of the site, where a storage tank farm was previously located. Challenges include: - The complex history of the site both relating to site use and Pier construction. Pier development began in the 1800's and was undertaken by many different entities. Modifications and repairs were made over the years resulting in several different types of Pier walls and fill that must be

Harbor. Discharge to the harbor is controlled by the 'new' Charles River Dam in Boston (fig. 1). The Basin was created by construction of the 'old' Charles River Dam in 1908 to solve Boston's sanitary problems. Prior to the building of the old Charles River Dam, the lower Charles River was a tidal estuary in which the water levels rose and fell twice daily with the tidal cycle. Low tide would expose untreated sewage that was discharged directly into the river. Exposed sewage created noxious odors and served as a breeding ground for mosquitoes that caused sporadic epidemics of malaria and yellow fever (Jobin, 1998). Damming of the river interrupted the normal tidal cycle and flooded the estuary by creating a freshwater pool (the Basin) that had a constant water elevation of about 0.8 meters (m) above mean sea level. Flooding of the estuary initially improved sanitary conditions and the Basin became a source of enjoyment for the local population and the focus of a large waterfront park in Boston and Cambridge (Jobin, 1998).Although the infiltration of saltwater from the harbor into the Basin was anticipated when the old Charles River Dam was built, neither the magnitude nor the consequences of the infiltration was considered. By 1975, the Metropolitan District Commission (MDC) determined that harbor water covered about 80 percent of the river bottom within the Basin and composed about 50 percent of its depth. The MDC also concluded that fish kills and odors in the spring of 1975 were likely the result of the sulfide-rich saltwater mixing with the overlying freshwater (Metropolitan District Commission, 1975).Saltwater from Boston Harbor that enters the Basin is known as the 'salt wedge' because of the shape it assumes as it moves upstream. Freshwater discharge from upstream pushes against the intruding harbor water until the density differences cause stratification to occur; the freshwater then overrides the denser harbor water (Fischer and others, 1979).

On Friday, 22 April 1994, a new science exhibition ``Infinitos", arranged jointly by Lisboa'94, CERN and ESO, will open at the Museu de Electricidade on the waterfront of Lisbon, the capital of Portugal. In a series of spectacular displays, it illustrates man's current understanding of how the Universe works - from the tiniest structures of matter to the most far flung galaxies. On this day, it will be inaugurated by the President of Lisboa'94, Prof. Vitor Constancio, the Portuguese Science Minister, Prof. L. Valente de Oliveira, Prof. C. Llewellyn Smith, Director General of CERN [2] and Dr. P. Creola, President of ESO Council. This exhibition is part of a rich cultural programme taking place at Lisbon during 1994 in the frame of ``Lisboa 94 - European City of Culture", after which it will travel to major cities around Europe. The frontiers of our knowledge push into inner space - the structure of the smallest components of matter - and into outer space - the dramatic phenomena of distant galaxies. Two of Europe's leading science organisations are playing a crucial role in this great human adventure. The European Laboratory for Particle Physics, CERN, operates the mighty accelerators and colliding beam machines to penetrate deep into matter and recreate the conditions which prevailed in the Universe a tiny fraction of a second after the Big Bang. The European Southern Observatory, ESO, operates the largest optical observatory in the world with a range of advanced telescopes searching the sky to study the evolution and content of our Universe. The ``Infinitos'' exhibition uses many modern exhibition techniques, including sophisticated audio-visual presentations and interactive video programmes. Visitors enter through a gallery of portraits of the most celebrated scientists from the 16th to 20th centuries and an exhibition of art inspired by scientific research.

, disminuyeron la esfera y el cilindro promedio de forma muy similar. La variación de la aberración esférica y el coma en ambas técnicas no fue significativa. Se recuperaron más rápidamente, desde el punto de vista anatómico, los ojos operados con la técnica de Epilasik.OBJECTIVE: To assess the effectiveness of Excimer laser surgery, using either epithelial laser in situ keratomileusis (Epilasik or laser-assisted epithelial keratectomy as surgical techniques, on the basis of a topoaberrometric study of patients with compound myopic astigmatism. METHODS: A prospective study was conducted in the Anterior Segment Service of "Camilo Cienfuegos" International Center of Pigmentary Retinitis. Eighty eyes from 40 patients with compound myopic astigmatism (-1 to -6 dioptres were studied, with a minimal follow-up of 6 months. Visual acuity without correction, keratometry, dynamic refraction, cycloplexic refraction, corneal topography, pachymetry, tonometry, biomicroscopy, study of the tear and funduscopy were all evaluated. The corneal waterfront analysis software was used for all the cases. Lasek was the chosen technique for right eyes whereas Epilasik was used for left eyes, using optimized refractive keratectomy in both procedures. RESULTS: In those cases treated with Lasek technique, visual acuity without correction changed from 0,12 to 0,93; preoperative sphere average changed -2,77 to -0,08 dioptres at the postoperative phase, the cylinder went from -79 to -0,37 dioptres, spheral aberration at 6mm slightly changed from 0,22 to 0,24 um and the coma varied from 0,19 to 0,20 um. In the cases subjected to Epilasik, visual acuity without correction varied from 0,07 to 0,93; the preoperative sphere average modified from -3,79 to 0,01 dioptres in the postoperative period, the cylinder went from -1,25 to -0,35 dioptres, spheral aberration at 6mm changed from 0,26 to 0,39 um, and the coma varied from 0,19 to 0,22 um. As to confocal microscopy, it was observed that recovery was faster

and waterfront areas with " general" carrying capacity levels are appropriate for modem ecological farming.The areas between mid-stream and up-stream of rivers with poor "lower" and "lowest" carrying capacity are ideal to cultivate staple crops (rice,cotton,rape,wheat,soybeans,and corn).This area is the main source of agricultural and domestic pollutants.In addition,the suitability of the industrial system has significant feedback for the water environment's carrying capacity.More measures should be taken to strengthen protection for wetlands along the lakeside due to its high ecological sensitivity.Unlike traditional hydrologic methods (using field hydrological data and model),this study provides a new approach to quickly and conveniently assess water environment carrying capacity.The industrial orientation proposed here serves not only an academic and scientific purpose,but also provides important insights for the government to formulate plans for industrial development.%区域的产业发展与该区域的自然和社会经济因素密切相关,对于水网稠密地区,水环境承载力是影响产业结构和布局优化的重要自然因子之一.选择江苏省境内跨长江与淮河两大流域的典型水网密集区——扬州市北部沿湖(邵伯湖)地区为研究区,选取水网构成指数、水利设施调控指数和水质达标差距指数3个指标,评价研究区水环境承载能力,并探讨水环境承载力与不同产业结构的联系,为该地区产业结构布局和优化提供建议.结果表明研究区水环境承载力“高”、“较高”、“中等”、“较低”和“低”5个等级分别占研究区总面积的0.38％、21.74％、29.67％、13.65％和34.56％.根据研究区水环境承载力空间差异和水环境承载力与不同产业的联系,以选择生态涵养型产业为基本导向,以兼具开发适宜性和环境保护重要性为基本原则,提出应根据研究区水环境承载力水平不均衡的�

of aperiodic order in two dimensions and used in modelling quasicrystalline materials, some ten years before quasicrystals were first seen in experiment. The conference excursion and dinner centred on the historic waterfront area of this 800-year old city that was designated European Capital of Culture in 2008. The enjoyment of the ferry trip on the Mersey and subsequent walk to the Albert dock museums was greatly enhanced by the fine weather, which lasted throughout the entire conference week. The guests of honour at the conference dinner were Professor Sir Roger Penrose FRS and Professor Alan L Mackay FRS, bringing together two distinguished UK scientists who made seminal contributions to the subject. Besides the scientific programme, the conference also offered a presentation by the author Ann Lingard, whose latest novel The Embalmer's Book of Recipes features a mathematician working on quasicrystals at the University of Liverpool as its main character. A related EPSRC-supported workshop on Mathematical Aspects of Aperiodic Order, organised by Alex Clark, John Hunton and Uwe Grimm, was held in Leicester in the week preceding the conference, and attracted about 40 participants. It is not possible to organise a conference without the help and support of a large number of people, and we would like to take this opportunity to acknowledge the support of everyone who was involved in organising and running this conference. We would like to thank the IUCr Aperiodic Commission, and in particular its chair Professor Marc de Boissieu, who not only entrusted us with hosting the event, but acted as the International Advisory Committee and provided valuable advice and guidance. We are indebted to the members of the International Programme Committee, who helped to put together an exciting programme by suggesting invited speakers and selecting presentations for contributed plenary talks. We are immensely grateful to all members of the National Organising Committee, who provided
