Progress in.Application of Runoff Simulation Based on SWAT

The development course and structure of SWAT model was introduced. Progress in the application of runoff simulation based on soil and water assessment tool .model was reviewed with some emphasis. Then the applicability of runoff simulation based on SWAT in different are- as or in different regions and time scales were summarized. And the hydrological response to land use-cover changes and climate changes were simulated in the model application. The further research on improving the model for applicability and simulation accuracy was put forward. Fi- nally, the problems and insufficiencies which exist in the model were discussed in domestic, and the main recommended research needs for using SWAT well in China was also presented.
