Watershed Models
WWQTCS Info
Watershed models play an important role in linking sources of pollutants to receiving waterbodies as nonpoint source loads. Watershed models are driven by precipitation, landuse, imprevious areas, slope, soil types and drainage area. GIS programs like BASINS and WCS provide the data that is needed for waterhd models to predict both water and pollutant runoff from a watershed.
