Abstract :
Modeling of hydrological components (especially streamflow) is the basis of water resources management and utilization. This study intended to validate the Soil and Water Assessment Tool (SWAT) model in Fu River Basin of a typical red soil area of China. The datasets of SWAT for simulation were established using ArcGIS 9.2. Based on the sensitivity analysis, 22 parameters were selected for atuocalibration. Among the parameters, Alpha_Bf was found to be the most important one. Then, the optimum parameters were given using daily observed streamflow during 1960-1970. Lastly, the daily streamflow simulation was performanced from 1971-2000 with the optimum parameters, and the results of validation showed that the simulated values were reasonable compared to the observed data with Ens being 0.76, 0.96 and 0.97 on daily, monthly and yearly respectively, suggesting that the validity of SWAT model in Fu River Basin of red soil area, China.
