Research on Water Reservoir Automation;

The analysis method, the new method calculating reservoir capacity, is put forward on the basis of topographic map, without area meter and no reservoir cross-section.

In this paper, soil erosion has been evaluated and predicted, countermeasures are proposed to provide a theoretical basis for comprehensive management on Wuba reservoir area.
