Sediment Yield Evaluation by Using QSWAT

Sediment yield is the amount of sediment eroded from the land surface by runoff and delivered to a stream system or at the basin outlet over a period of time. Estimates of sediment yield are needed for studies of reservoir sedimentation, river morphology and planning of soil and water conservation measures. The present study has been carried out by using Soil Water Assessment Tool (SWAT) for GV – 48 area located in the Gangapur Taluka of Aurangabad district. SWAT requires large number of input parameters. Digital maps viz. Digital elevation model, soil map, Land use land cover map required for input of SWAT have been prepared by using QGIS. From various Government agencies and sources; all the required thematic maps and attribute information of study area have been collected. The simulated result is obtained which can be visualize statically, graphically and numerically.
