dc.description.abstractAs prevention of disasters concerning flooding in coastal urban area, this study has developed the real time monitoring system aimed at the On-cheon stream in Busan. The basis of this study was a selection of various geological data based on the numerical map and computation of hydrologic GIS data. Thiessen polygon method was used to analyze rainfall on this site. And regression equation of 6th degree and Huff's Type II was used for investigating time-distribution of rainfall. To estimate warning standard rainfall and flood discharge, risk depth was selected on Sebyeong bridge site. Flood depth and threshold runoff considering the effect of tidal water level was estimated for hydraulic analysis using HEC-RAS and urban flash flood rainfall were evaluated using PCSWMM 2002. Consequently, this study estimated warning standard of rainfall and flood discharge using ArcView GIS, HEC-RAS and SWMM on the study area. And real time monitoring system developed is to study various cases on a variety of basins to reduce natural disasters induced by flood in coastal urban area.
