Abstract

A distributed watershed hydrologic model, SWAT was applied to simulate stream flow and nutrient loadings (TN, NO3-, TP) in Meiling watershed, which is sub-watershed of Taihu Lake Basin. Model parameters were calibrated and validated using the measured data. The results were satisfactory; the evaluation coefficients for daily calibration were: Person's correlation coefficient is 0.73, Nash-Sutcliffe coefficient is 0.63. The simulated daily mean value of TN and TP were 1.545kg/ha and 0.025 kg/ha, close to the measured value, viz. 1.901 kg/ha and 0.043 kg/ha respectively, suggesting the validity of SWAT. The simulation provides better understanding on stream flow and nutrient loading in response to agricultural tillage operation and natural rainfall.
