The Multi-Resolution Watershed Model Based on DEM

Abstract:

The multi-resolution flooding routing model advanced firstly is composed of the extensive flooding routing model and the fine flooding routing model. In the article to put up research and discuss detailedly the 3D visualization of the mul-resolution flooding routing model which is as the non-engineering measure about the water conservancy management. In the article to analysis the constructing method of the mul-resolution flooding routing model mainly ,which is the theory and method about the extensive flooding routing model and the fine flooding routing model constructed and to work out material the extensive flooding routing model and the fine flooding routing model. Finally to applying the statistic analysis method to get the below conclusion: ①Applying the visualization system about the multi-resolution flooding routing model is to act the non-engineering measure about the water conservancy management and it provides a new thought and trusty scientific decision-making for the water conservancy management department; ② The results of the storage capacity and the submergence area worked out by the the fine flooding routing model are more precision than the result of the general method. The above conclusion proves the feasibility and science about the construction of the multi-resolution flooding routing model adequately.
