Abstract: This paper forecasts precipitation and runoff of Fengle River Watershed with a distributed hydrological model –SWAT (Soil and Water Assessment Tool) model. Based on different soil types and land use classifications in the catchment, AVSWAT2000 model divide the watershed into 38 subbasins and 131HRUs (Hydrological Response Units), each of which is comprised of unique hydrological characteristic. With precipitation gauging materials of Taoxi hydrological station in 2000—2003, the more sensitive hydrology factors were calibrated, satisfactory simulation results were obtained with the highly fitting accuracy, which suggests an excellent modeling performance for hydrology simulation and prediction of the study basin. By the integration of meteorological forecasting model with AVSWAT2000, risk and normal hydrological processing was forecasted. Monthly distribution of precipitation and runoff in typical and normal years was detected, which offers reference for water resources management of basin. This perdition method is a primary trial to the distributed model integration studying, and has active significance to further study.
