Soil and water assessment tool (SWAT)
Soil and water assessment tool (SWAT)is an effective tool and is used in a hydrological cycle in watershed. It is in fact a time simulation model of the land phase hydrological cycle that operates on a daily time step at basin scale.SWAT is a public domain model jointly developed by USDA Agricultural Research Service (USDA-ARS) and Texas A&M Agri Life Research, part of The Texas A&M University System.
Soil and Water Assessment Tool (SWAT) is a river basin scale model developed to quantify the impact of land management practices in large, complex watersheds.SWAT enables the modeling of process associated with water movement, sediment movement, crop growth and nutrient cycling.Soil and Water Assessment Tool is designed in such a way that it has the capability to incorporate information about topography, vegetation, weather, soil properties and other associated land management practices.
Soil and water assessment tool (SWAT) has the capability to access, predict and analyze the impact of various land management practices on sediment ,water, and agricultural chemicals yields in large complex watershed having presences of varying land use & management and soils conditions prevailing over a longer duration in watershed .
SWAT is widely used in assessing soil erosion prevention and control, non-point source pollution control and regional management in watersheds.
