The Soil and Water Assessment Tool (SWAT) is a river basin, or watershed, scale model 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.  The model is physically based and computationally efficient, uses readily available inputs and enables users to study long‐term impacts.  Input parameters for perennial switchgrass growth include Chemical applications, existing land cover, elevation data, soils, hydrology, and climate. Output from SWAT includes: total sediment, nitrogen and phosphorous loading, and other water quantity characteristics.
