Summary
Abstract: SWAT is the acronym for Soil and Water Assessment Tool, a river basin, or
watershed, scale model developed by Dr. Jeff Arnold for the USDA Agricultural
Research Service (ARS). SWAT was developed to predict the impact of land
management practices on water, sediment and agricultural chemical yields in
large complex watersheds with varying soils, land use and management conditions
over long periods of time.
