Abstract

The objective of this study is to develope estimation techniques of flood inundation area for given rainfall frequency using GIS. For this, Namdae-cheon is selected as pilot station and Inundation area is estimated with routing of flood volume from river mouth to upstream. As a results inundation area of Namdae-cheon estimated with $1.5km^2\~9.7km^2$ for $5\~500$ frequency years. In addition it is noted that results of this study can use in flood risk analysis for establishment of flood countermeasures.
