Abstract:
The present study is based on SWAT (Soil and Water Assessment Tool) Model which integrates the GIS information with attribute database to estimate the runoff of Shakkar River catchment. Soil and Water Assessment Tool (SWAT) is a physically based distributed parameter model which has been developed to predict runoff, erosion, sediment and nutrient transport from agricultural watersheds under different management practices. The SWAT Model works in conjunction with Arc GIS. In the present study the catchment area has been delineated using the DEM (Digital Elevation Model) and then divided into 23 sub-basins. For preparation of landuse map, the LANDSAT images are downloaded from earth explorer and the soil map is extracted from NBSS. The sub basins are further divided into 223 HRUs which stands for Hydrological Response Unit. Then by using 21 years of daily rainfall data and daily maximum and minimum temperature data SWAT simulation is done for daily basis to find out Runoff for corresponding Rainfall. The coefficient of correlation (r) for rainfall in a period and the corresponding runoff is found to be 0.8019.
