Application of SWAT Hydrological Model to Simulate Flow of Seti-Gandaki Basin

The Soil and Water Assessment Tool (SWAT), a semi-distributed hydrological model, has been used for the Seti-Gandaki River Basin (SGRB) to simulate streamflow. Further, SWAT was assessed study water balance of basin. This primarily focuses on different features modeling like multi-site calibration validation streamflow with view check reliability model in high precipitation basin Nepal. statistics performance is evaluated using various statistical test Nash-Sutcliffe, RMSE, Kling Gupta Efficiency (KGE). Moreover, parameters Nash-Sutcliffe efficiency (NSE), Percentage Bias (PBIAS), Coefficient Variation (R2), ratio root mean square error standard deviation measures data (RSR), (KGE) evaluate carryout0.93(0.89), -0.04(-21.87), 0.95(0.94), 0.26(0.34), 0.85(0.76), respectively, (and validation) at Damauli station. annual flow SGRB observed be 209 m3/s 2866 mm, respectively. About 20% seems lost as evapotranspiration. results showed that performed better daily monthly periods. Overall, versatility an appropriate tool resources over region. output can helpful planning management basins.
