At present, there isn't a flexible and actually running distributed hydrological model in the Hai river basin. Based on SWAT (Soil and Water Assessment Tool), a whole basin distributed hydrological model for Hai River basin is presented. In this model, according to the Hai river basin characteristics, the river networks in the plain region is reasonably modified, the 17 river mouths are generalized, the 28 big reservoirs are considered. Because of the difference between China and USA, the soil type database and land use types are transformed and reclassified. By using the hydro meteorological data from 1995 to 2002, we carry on the optimization and sensitivity analysis of the model parameters based on the parameters analysis system building by ourselves. The simulation results are reasonable and can provide the important hydrology supporting foundation for the water resources management and the eco- environment's restoration in the Hai river basin.
