| The objectives of this study are to introduce flash flood forecasting system in Korea and to develop a system for computing threshold runoff on very fine catchment scale. The developed GUI system composed of 9 steps starting from input data preparation to Input file creation for flash flood forecasting compute basin subdivision, hydrologic subbasin characteristics, bankfull flows, unit peak flows and threshold runoffs on about 5 $ extrm{km}^2$ scale. When the developed system was applied on Pyungchang IHP basin, the computed 1-hour threshold runoffs ranged 18.72~81.96mm with average value of 46.39mm. Judging from the comparison of the computed threshold runoffs between this study area and three other basins in United States, the computed results in this study were reasonable. It can be concluded that the developed system on ArcView/Avenue are useful for computing threshold runoff on small catchment and can be used as a component of flash flood forecasting system. |
