GIS를 활용한 홍수유역의 유출량 산정 = Calculation of Runoff in Flood Basin Using GIS

다국어 초록 (Multilingual Abstract)

In order to investigate the effect of a pouring rain that it follows in the typhoon, the effect analysis with actual measurement data of rainfall outflow it follows in flood basin is necessary. Also there is a case that it analyzes with the fact that the rainfall occurs identically in whole basin in case of the rainfall outflow analysis, but the actual rainfall distribution from the basin very will be irregular and the interpretation which it reflects must become accomplished. It created spatial information of terrain, land use and the soil using GIS. It created topographical factor of the subject area and calculated CN(runoff curve number) with WMS(Watershed Modeling System). It calculated runoff using a HEC-1 model and the Rational Method connected at the WMS. By connecting GIS and WMS, it calculated the effect of a pouring rain and runoff from the construction area. Also it will be able to apply with a basic data in more efficient runoff analysis.
