Analysis of nature-based treatment of surface water runoff from an informal settlement to irrigate vegetables
… irrigation with biofiltration-treated surface runoff from IS. Municipal Treated Water (MTW) was used alongside Biofiltration-treated Water (BTW) to irrigate crops for nine months. Three soil treatments were prepared along each irrigation system mirroring each other: 1) control soil, 2) …

Occurrence, Fate and Transport of the Primary Metabolites of Trenbolone Acetate in CAFO Soils and Surface Water Runoff
… pose a demonstrated ecological risk to waterways adjacent to beef feedlot operations. For example, numerous studies have linked reproductive abnormalities in fish species to the presence of 17-α trenbolone and 17-β trenbolone, the primary metabolites of the synthetic steroid trenbolone …

An analysis of nature-based treatment processes for cleaning contaminated surface water runoff from an informal settlement: a case study of the Stiebeuel River catchment, Franschhoek, South Africa
Contaminated surface water runoff from inadequate drainage and sanitation systems in informal settlements threaten the quality of available freshwater and can negatively impact both human and environmental health. Biofiltration systems (biofilters) provide water pollution controls without inputs of …

Stormwater Runoff from Elevated Highways: Prediction of COD from Field Measurements and TSS
… oxygen demand (COD) concentrations in storm water runoff from elevated roadways, which transports a significant load of contaminants. The objective of this research was to develop a mathematical model to relate COD concentration to different measurable parameters which are easily available …

Influence of geology on the water resources of the Upper Roanoke River Basin, Virginia
… Geohydrologic analyses of climate, surface-water, ground-water, and water-quality data identified the geohydrologic characteristics of each unit. Precipitation on 15 subbasins during the study year (April 1969 to March 1970) ranged from 30.77 to 39.68 inches; potential evapotranspiration …

Hydrological urbanism in China's Pearl River Delta : how water landscape shapes the urban form in a changing climate
… without considering natural system. Storm water runoff causes flooding in the cities every year, and at the same time, extreme weather events linked to climate change and sea level rise threatens urban life and property in the future. This thesis proposes hydrological urbanism which not …

Water Urbanism: Fish Market Design Proposal
… transportation, fertile land to grow crops, water for drinking, washing, livestock and other domestic uses and food in the form of fish. Gradually, they came to define cities, became a part of identities of people, such as "India" from "Indus," while, providing a sense of place and connecting …

Integrated Life Cycle Analysis Approach (ILCA2) for Transportation Project and Program Development
… cycle impacts include waste materials and storm water runoff. These life cycle impacts have associated costs. Life Cycle Cost Analysis (LCCA) is a commonly used methodology which analyzes life cycle costs of projects. However, this methodology does not include costs associated with environmental …

Assessment of Sediment Runoff from Natural Gas Well Development Sites.
Storm water sediment runoff from disturbed landscapes has the potential to impair aquatic environments. Small construction sites of 1-5 acres in the United States are currently regulated by the United States Environmental Protection Agency to minimize storm water runoff damages to the environment. …

Instrumenting Wildlife Water Developments to Collect Hydrometeorologic Data in Remote Nevada Catchments
… models estimating the contribution of surface water runoff to groundwater recharge often require inputs of precipitation data. However, models estimating precipitation in Nevada are based on extremely limited data, especially in remote, mid- to high-elevation catchments. Wildlife water …

Buildup/Washoff Model for Dissolved Iron in Stormwater Runoff
… Interstate-610, New Orleans, Louisiana. Storm water runoff from the examined elevated roadway section was analyzed for 14 storm events. The model used a linear function of antecedent dry time for the buildup model. The rating curve assumption was selected to estimate the pollutant transport …

A system model for source water assessment in the Las Vegas Valley
The 1996 amendment to the Safe Drinking Water Act of 1974 created the Source Water Assessment Program (SWAP) with an objective to evaluate potential sources of contamination to drinking water intakes. The development of a Source Water Assessment Plan for Las Vegas Valley surface water runoff into …

The Effect of Antecedent Dry Time on Water Quality Inflow and Outflow to Wet Ponds and Pollutant Removal Efficiency
Storm water is a significant source of pollutants in urban areas. Urbanization results in reduced water quality of surface waters due to the loss of vegetation and pervious areas, and increased impervious cover, pollutant loading, and volume and velocity of storm water runoff. The potential for …
