Reservoir Capacity Measurement and its Curve Preparation Based on DEM

Abstract:

A precise and reliable basic data is an important for flood control and management for each reservoir, especially DEM. The topographic map above water surface can easily be digitized based on GIS technology. The underwater digital elevation model (DEM) was measured integrated with GPSRTK technology and precision shallow water echo sounder. Therefore, DEM overall reservoir area can be built by integrating these two results. Using the methods of this paper, the reservoir capacity can be automatically generated, reservoir storage capacity table can be automatically prepared, and reservoir capacity curve can also be automatically drawn. The applications in the Guxian and Baisha Reservoir show that this method is simple and feasible.
