The Soil and Water Assessment Tool is an open-source catchment model developed by Blackland Research Center & Texas A&M University (USA).
MOdel developments At HYDR department
HYDR is involved in model developments for the SWAT. Our recent contributions are:
1) Improvements for use of SWAT in Tropical catchments (Alemayehu et al., 2017)
2) Improvements for water quality simulations (Woldegiorgis et al., 2017; Hoang et al., 2017)
3) Linking to calibration & uncertainty analysis tools (van Griensven et al., 2006)
4) Improvement of evapotranspiration and the use of SWAT for Water Productivity and Water Accounting applications
5) Python based workflows for SWAT set-up
We are involved in several projects with applications in:
1) the Pangani basin (Tanzania)
2) the Blue Nile basin (Ethiopia/Sudan)
3) the Niger basin
4) the African continent
