SWET WORKSHOP AND CONFERENCE - July 2007, the Netherlands

The Soil and Water Assessment Tool (SWAT) is a public domain model actively supported by the USDA Agricultural Research Service at the Grassland, Soil and Water Research Laboratory in Temple, Texas, USA. SWAT is a distributed model designed to simulate water, nutrient and pesticide transport at a catchment scale on a daily time step.It represents hydrology by interception, evapotranspiration, surface runoff, soil percolation, lateral flow and groundwater flow and river routing processes.The main purpose of the model is to predict effects of management (climate and vegetative changes, reservoir management, groundwater withdrawals, water transfer) on water sediment and chemical yields on large river basins. SWAT can analyze meso- to macroscale watersheds by subdividing the area into homogenous parts. SWAT is imbedded in a GIS interface.
