| Abstract: | The continuity of flooded region was analyzed by use of the expansion operator in mathematical morphology,and the discrete elevation data of flooded region were obtained by GIS lattice data.Based on the calculated result,the water depth distribution and flooded region were computed by the principle of volumetric method. |
