چکیده مقاله
Soil and water conservation is important for the Torogh reservoir area in Khorasan razavi province, and quantification of soil loss is a significant issue In this study, two widely used models the Water Erosion Perdiction Project WEPP and the Soil and Water Assessment Tool SWAT were applied to simulate runoff and sediment yield for the Torogh watershed in the Torogh reservoir area The models were run and the simulated runoff and sediment yield values were compared with the measured runoff and sediment yield values In the calibration period, the model efficiency ENS values for the WEPP and SWAT were 0 864 and 0 711 for runoff, and 0 847 and 0 678 for sediment yield, respectively In the validation period, the ENS values for WEPP and SWAT were 0 835 and 0 690 for runoff, and 0 828 and 0 818 for sediment yield, respectively The results of ENS and the other criteria indicate that the results of both models were acceptable WEPP simulation were better than SWAT in most cases, and could be used with a reasonable confidence for soil loss quantification in the Torogh watershed
