For this analysis, the Manot sub-basin region of Upper Narmada Basin located in Madhya Pradesh, India, is designated for estimation of runoff, sediment load, sediment concentration and sediment yield using SWAT. The model was implemented during 1989 and 2008. NBSSLUP soil data, Digital Elevation Model (DEM), slope, Land use Ground cover (LULC) and climate records of temperature and rainfall were used as inputs for the Manot Gauge Station. The forecasted model discharge was estimated statistically and compared the real daily flow data from 1989 to 2008, which corresponds to a major number. The R2 value (coefficient of determination) for discharge, sediment concentration, sediment load and sediment yield values for the period 1989 to 2008 were found to be 0.95, 0.94, 0.96 and 0.96 respectively. RMSE for discharge, sediment concentration and sediment yield were found to be 0.32, 0.27 and 0.17, respectively. The expected sediment load at the Manot Gauge Station for the duration (1989–2008) is 6670918 tons per year and the observed sediment load is 6255565 tons per year. Simulated sediment load and measured sediment load at the Manot Gauge Station are 14.13 tons / year / hectare and 15.02 tons / year / hectare, respectively. Predicted sediment concentrations and measured sediment concentrations at the Manot gauging station were found to be 8.81 ppm and 7.46 ppm, respectively. Similarly, the expected and observed Sediment Yield was 1.513 mm and 1.704 mm respectively.
