Better Assessment Science Integrating Point and Nonpoint Sources
Impact/Purpose:
Refine risk assessment science
Description:
Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) is not a model per se, but is a multipurpose environmental decision support system for use by regional, state, and local agencies in performing watershed- and water-quality-based studies. BASINS was developed by the U.S. Environmental Protection Agency's (EPA's) Office of Water to address three objectives: (1) To facilitate examination of environmental information, (2) To support analysis of environmental systems, and (3) To provide a framework for examining management alternatives. BASINS provides both simple (e.g. PLOAD) and temporally detailed (e.g. HSPF, SWAT, SWMM) models for simulating hydrologic and pollutant loads/concentrations emanating from watersheds. BASINS also provides direct linkages between watershed and detailed aquatic ecosystem simulation models (AQUATOX, WASP), to facilitate analysis of watershed impacts on aquatic ecosystem processes.
