Sustainable Drainage System
Sustainable drainage systems (also known as SuDS,Sustainable Drainage System (SuDs) for Stormwater Management: A Technological and Policy Intervention to Combat Diffuse Pollution Sharma, D., 2008 SUDS, or sustainable urban drainage systems) are a collection of water management practices that aim to align modern Stormwater drain, drainage systems with natural water processes and are part of a larger green infrastructure strategy. SuDS efforts make urban drainage systems more compatible with components of the natural water cycle such as storm surge overflows, soil percolation, and bio-filtrati ...

Great Stink
The Great Stink was an event in Central London during July and August 1858 in which the hot weather exacerbated the smell of untreated human waste and industrial effluent that was present on the banks of the River Thames. The problem had been mounting for some years, with an ageing and inadequate sewer system that emptied directly into the Thames. The miasma theory, miasma from the effluent was thought to transmit contagious diseases, and three outbreaks of cholera before the Great Stink were blamed on the ongoing problems with the river. The smell, and fears of its possible effects, prompted action by the national and local administrators who had been considering possible solutions to the problem. The authorities accepted a proposal from the civil engineer Joseph Bazalgette to move the effluent eastwards along a series of interconnecting sewers that sloped towards outfalls beyond the metropolitan area. Work on high-, mid- and low-level systems for the new Northern Outfall Sewe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flash Flooding
A flash flood is a rapid flooding of low-lying areas: washes, rivers, dry lakes and depressions. It may be caused by heavy rain associated with a severe thunderstorm, hurricane, or tropical storm, or by meltwater from ice and snow. Flash floods may also occur after the collapse of a natural ice or debris dam, or a human structure such as a man-made dam, as occurred before the Johnstown Flood of 1889. Flash floods are distinguished from regular floods by having a timescale of fewer than six hours between rainfall and the onset of flooding. Flash floods are a significant hazard, causing more fatalities in the U.S. in an average year than lightning, tornadoes, or hurricanes. They can also deposit large quantities of sediments on floodplains and destroy vegetation cover not adapted to frequent flood conditions. Causes Flash floods most often occur in dry areas that have recently received precipitation, but they may be seen anywhere downstream from the source of the precipit ...

Urbanisation
Urbanization (or urbanisation in British English) is the population shift from rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It can also mean population growth in urban areas instead of rural ones. It is predominantly the process by which towns and cities are formed and become larger as more people begin to live and work in central areas. Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from urban growth. Urbanization refers to the ''proportion'' of the total national population living in areas classified as urban, whereas urban growth strictly refers to the ''absolute'' number of people living in those areas. It is predicted that by 2050, about 64% of the developing world and 86% of the developed world will be urbanized. This is predicted to generate artificial scarcities of land, lack of drinking water, playgrounds and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impervious Surface
Impervious surfaces are mainly artificial structures—such as pavements (roads, sidewalks, driveways and parking lots, as well as industrial areas such as airports, ports and logistics and distribution centres, all of which use considerable paved areas) that are covered by water-resistant materials such as asphalt, concrete, brick, stone—and rooftops. Soils compacted by urban development are also highly impervious. Environmental effects Impervious surfaces are an environmental concern because their construction initiates a chain of events that modifies urban air and water resources: * The pavement materials seal the soil surface, eliminating rainwater infiltration and natural groundwater recharge. This can cause urban flooding. An article in the '' Seattle Times'' states that "while urban areas cover only 3 percent of the U.S., it is estimated that their runoff is the primary source of pollution in 13 percent of rivers, 18 percent of lakes and 32 percent of estuari ...

Nationwide Urban Runoff Program
The Nationwide Urban Runoff Program (NURP) was a research project conducted by the United States Environmental Protection Agency (EPA) between 1979 and 1983. It was the first comprehensive study of urban stormwater pollution across the United States. Study objectives The principal focus areas of the study consisted of: * Examine the water quality aspects of urban runoff, and a comparison of results across various urban sites * Assess the impact of urban runoff on overall water quality * Implement stormwater management best practices. A major component of the project was an analysis of water samples collected during 2,300 storms in 28 major metropolitan areas. Findings Among the conclusions of the report are the following: * "Heavy metals (especially copper, lead and zinc) are by far the most prevalent priority pollutant constituents found in urban runoff...Copper is suggested to be the most significant hreat/nowiki> of the three." * "Coliform bacteria are present at high leve ...

National Research Council (United States)
The National Academies of Sciences, Engineering, and Medicine (NASEM), also known as the National Academies, is a congressionally chartered organization that serves as the collective scientific national academy of the United States. The name is used interchangeably in two senses: (1) as an umbrella term or parent organization for its three sub-divisions that operate as quasi-independent honorific learned society member organizations known as the National Academy of Sciences (NAS), the National Academy of Engineering (NAE), and the National Academy of Medicine (NAM); and (2) as the brand for studies and reports issued by the unified operating arm of the three academies originally known as the National Research Council (NRC). The National Academies also serve as public policy advisors, research institutes, think tanks, and public administration consultants on issues of public importance or on request by the government.

Water-sensitive Urban Design
Water-sensitive urban design (WSUD) is a land planning and engineering design approach which integrates the urban water cycle, including stormwater, groundwater, and wastewater management and water supply, into urban design to minimise environmental degradation and improve aesthetic and recreational appeal.BMT WBM 2009, "Evaluating options for water sensitive urban design – a national guide: Prepared by the Joint Steering Committee for Water Sensitive Cities: In delivering Clause 92(ii) of the National Water Initiative", Joint Steering Committee for Water Sensitive Cities (JSCWSC), Canberra, viewed 18 September 2011. WSUD is a term used in the Middle East and Australia and is similar to low-impact development (Canada/US), low-impact development (LID), a term used in the United States; and Sustainable Drainage System (SuDS), a term used in the United Kingdom. Common approaches include reducing potable water use and collecting greywater, wastewater, stormwater, and other runoff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-impact Development (Canada/US)
Low-impact development (LID) is a term used in Canada and the United States to describe a land use planning, land planning and environmental engineering, engineering design approach to manage stormwater surface runoff, runoff as part of green infrastructure. LID emphasizes water conservation, conservation and use of on-site natural features to protect water quality. This approach implements engineered small-scale hydrologic controls to replicate the pre-development Surface-water hydrology, hydrologic regime of Drainage basin, watersheds through infiltration (hydrology), infiltrating, filtration, filtering, storing, evaporation, evaporating, and detaining runoff close to its source. Green infrastructure investments are one approach that often yields multiple benefits and builds city resilience. Broadly equivalent terms used elsewhere include Sustainable drainage systems (SuDS) in the United Kingdom (where LID has Low-impact development (UK), a different meaning), water-sensitive ...

Best Management Practice For Water Pollution
Best management practices (BMPs) is a term used in the United States and Canada to describe a type of water pollution control. Historically the term has referred to auxiliary pollution controls in the fields of industrial wastewater treatment, industrial wastewater control and sewage treatment, municipal sewage control, while in stormwater management (both urban and rural) and wetland management, BMPs may refer to a principal control or treatment technique as well. Terminology Beginning in the 20th century, designers of industrial and municipal sewage pollution controls typically utilized sewage treatment, engineered systems (e.g. Trickling filter, filters, clarifiers, Bioreactor, biological reactors) to provide the central components of pollution control systems, and used the term "BMPs" to describe the supporting functions for these systems, such as operator training and equipment maintenance. Stormwater management, as a specialized area within the field of environmental engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxford Services
Oxford services is a motorway service station next to junction 8A of the M40 motorway at Waterstock near Wheatley in Oxfordshire, several miles to the east of the city of Oxford. It is named after the nearby city of Oxford. The services are owned by Welcome Break and opened in the summer of 1998. It was the third of four service stations to open on the M40. There is also a Ramada hotel on the site. There is also a Welcome Break area at the Peartree Roundabout. It is one of four services along the 89-mile M40 motorway; the others are Beaconsfield, Cherwell Valley and Warwick. It is also known as "Rippy Fountain" services, due to the water displays outside the park which are similar to the now defunct Ripsaw ride at Alton Towers. Sustainable Drainage System (SuDS) Oxford Services is the site of one of the United Kingdom's pioneering fully integrated Sustainable Drainage Schemes (Sustainable Urban Drainage Systems). Designed by Robert Bray Associates, the SuDS system comprises ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Sustainability
Sustainability is a social goal for people to co-exist on Earth over a long period of time. Definitions of this term are disputed and have varied with literature, context, and time. Sustainability usually has three dimensions (or pillars): environmental, economic, and social. Many definitions emphasize the environmental dimension. This can include addressing key environmental issues, environmental problems, including climate change and biodiversity loss. The idea of sustainability can guide decisions at the global, national, organizational, and individual levels. A related concept is that of sustainable development, and the terms are often used to mean the same thing. UNESCO distinguishes the two like this: "''Sustainability'' is often thought of as a long-term goal (i.e. a more sustainable world), while ''sustainable development'' refers to the many processes and pathways to achieve it." Details around the economic dimension of sustainability are controversial. Scholars have d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
