In this study,based on typical land consolidation project conditions,WEPP model was used to simulate the effects of different terrace configuration on soil and water conservation under different slopes and precipitation intensities.By the combination of different slopes,rainfalls and the terrace numbers,30 scenarios were set to model the soil loss and sediment yield.The results showed that WEPP model could quantitatively describe the loss of soil conditions on the slope with the mechanism of physical proces...
