| Abstract: | Based on the grid DEM,the necessary parameters for the numerical model were extracted automatically from the GIS database.The runoff and sediment yield model was re-developed by the VBA and the ESRI ArcObjects of COMGIS. The hydrological model and the sediment yield model were coupled together and the whole model was also coupled closely with the GIS.The distributed function of the model was achieved finally. |
