Simulation of Soil and Water Loss in the Upper Huaihe River Basin using the Xinanjiang Model

摘要

The Xinanjiang model is coupled with the Modified Universal Soil Loss Equation to simulate the soil and water loss in the upper Huaihe River. The outputs show that xinanjiang model can simulate runoff and sediment well, and the total runoff was generally less than 10% for both model calibration and validation with the Nash-Sutcliffe efficiency larger than 0.78 respectively. The computed sediment graphs were in good agreement with the observed ones, i.e. the relative errors of the computed total sediment yield was generally less than 20% for both model calibration and validation with the Nash-Sutcliffe efficiency larger than 0.62 respectively.
