SWAT project needs landuse and soil maps to create HRUs. HRUs or hydrologic response units are the units within a subbasin that possess unique combination of landuse, soil and slope. Each HRU shows a homogeneous hydrological response under similar climatic condition. Users can either directly upload landuse and soil map from local computer or load them from the MAGNET4WATER server.How to use it:
