| Recently, GIS softwares such as WMS, ArcHydro, and HyGIS which can calculate hydrological geographic parameters are popularized. These softwares have the functions to calculate various geographic parameters which are used in water resources from DEM (Digital Elevation Model). In this study, hydrological geographic parameters calculated by WMS and ArcHydro are compared and examined with them from HyGIS to evaluate the applicability of the parameters from HyGIS. Bochungcheon (Riv.), Wicheon (Riv.), Pyungchanggang (Riv.), Gyungancheon (Riv.), Naerincheon (Riv.), and Imjingang (Riv.) watersheds are selected for this study, and the shape of watershed, watershed area, watershed slope, the average slope of watershed, main stream length, main stream slope, maximum flow distance, and the slope of maximum flow distance are calculated to compare and examine the characteristics. Study results show that the average relative error of 7 geographic parameters from all the watersheds is 4.77 %, and all the watershed boundaries are very similar. So, all the geographic parameters calculated by each software show very similar value, and the geographic parameters calculated by HyGIS can be applied to water resources with WMS and ArcHydro which have been generally used. |
