SWAT hydrologic model

The Soil and Water Assessment Tool (SWAT) is the hydrologic model used in the SWAT/GRASS linkage (USDA/Arnold and others, 1995). SWAT is a continuous-time, basin-scale hydrologic model capable of complex long-term simulations including hydrology, pesticide and nutrient cycling, and erosion and sediment transport. It is a river basin scale model developed to quantify the impact of land management practices in large, complex watersheds. SWAT is a public domain model actively supported by the USDA Agricultural Research Service at the Grassland, Soil and Water Research Laboratory in Temple, TX.
