| Abstract: | The paper presents the features on calculation reservoir capacity by DEM and points out the changes of reservoir-bank conditions due to reservoir storage and their influences on accuracy of calculated reservoir capacity. It is feasible to modify reservoir calculation through implementing dynamic monitoring to reservoir bank and employing multicycle remote sensing data,DOM data and other related data to establish a real-time 3D GIS. |

| Keywords: | DEM(digital elevation model) reservoir-bank condition storage capacity |
