Abstract:
UCTOLD, IAWPRC and UCTPHO are activated sludge system diurnal simulation software programs written and compiled in TurboPascal 3.1 by the Water Research Group at the University of Cape Town in the late 1980s and early 1990s. IAWPRC is identical to International Water Association (IWA) Activated sludge Model No 1 (ASM1, Henze et al., 1987) and UCTOLD is an earlier variation of ASM1 that makes no material difference to simulation results when each are run with their default parameters – the difference is explained by Dold and Marais (1985).

Abstract:
Changes in land use and water use can greatly impact the cycling of water and water-borne substances. Increased redistribution of river water to irrigated fields can cause enhanced evapotranspiration and decreased river discharge. Additionally, the water quality can be affected by the external input of fertilisers and pesticides, and by changed pollutant transport pathways in expansive irrigation canal systems. This thesis examines basin-scale changes in water use, river discharge, water quality and nitrogen (N) loading under conditions of intensified irrigated agriculture, using the Aral Sea

Abstract:
Pollution from nonpoint sources is a leading cause of receiving water quality impairment. The largest source of nonpoint pollution is storm water runoff, which includes pollutants such as sediment, nutrients, metals, microorganisms, and organic compounds. Sediment is of particular importance because many pollutants are readily 5 adsorbed onto particles. In the Lake Tahoe basin, sediment is also significant because of its direct contribution to clarity attenuation. The most prudent control measure for mitigating sediment flux in the Lake Tahoe basin is infiltration, which captures runoff volume

Karst regions are composed of soluble rock, often limestone, which leads to the formation of fissures, sinkholes and water flow conduits such as caves. Pollutants in karst waters tend to be quickly directed and concentrated into these subsurface conduits.

Pollutant concentrations going into fluvial systems travelling through the subsurface in karst areas are often very similar to the concentrations arriving at outlets such as springs.

Abstract:
The aquatic ecology of the White River basin has been studied since 1875 with researchers having reported 158 fish species belonging to 25 families. Recently, an EPA 319 grant allowed for further research in the Upper White River basin. The two-year study (2002-2004) examined three watersheds in Delaware County for biotic integrity, habitat quality, and stream water quality parameters. Twenty-two sites were selected to gain a perspective on agricultural, urban, and wooded landscape influences in order to locate and implement Best Management Practices (BMPs). Samples exceeded established state

CoordenaÃÃo de AperfeiÃoamento de NÃvel Superior<br>During a period of three years surface waters from the Acaraà basin, in the North of Cearà State, were studied for an evaluation of the quality dynamics of the water used in the perenization of Acaraà river and in the irrigation schemes Araras Norte, Ayres de Souza, Forquilha, and Baixo AcaraÃ. A classification according the hydrochemical type and quality for irrigation, following criteria adopted by the United States Department of Agricultural - USDA and the University of California Commitee of Consultants â UCCC, was made for ten sampling p
