| In this study, Miho stream basin(Seokhwa water level gauging station) In Geum river, Flood control main station of Geum River Flood Control Office, is selected. Hydrologic topographical informations are calculated using WMS which is hydrologic analysis software coupled with GIS Method, and flood analysis is accomplished by HEC-1 included In WMS. To calculate the effective rainfall CN values of SCS are used. Clark, Snyder and SCS methods are selected respectively to derive unit hydrograph. This study shows the applicability of GIS techniques to runoff simulation in ungauged basin by comparing with actual measured flood hydrograph. As a results, Snyder(Tulsa) method and Clark (Herby) method is suitable to Miho stream basin. But Snyder(Tulsa) method is suitable more than Clark(Herby) method. And according to the degree of urbanization, the peak discharge has increased and the peak time has tended to decrease. |
