THE ESTABLISHMENT AND CASE STUDY OF THE MODEL FOR NONPOINT SOURCE POLLUTION FOR WATERSHED
流域非点源污染模型的建立与应用实例

A comprehensive model system of nonpoint source pollution(NSP) has been developed . The process model of NSP pollutant yield in basin and the model of watershed concentration and pollutant transportation and transformation Inverse gaussian distribution instantaneous unit hydrograph model were newly proposed. The calculated results for natural basins show that the model system can be applied to flood, sediment, and various pollutants effectively.
