Abstract: In the study Decision Support System (DSS) using Geographical Information System (GIS) is developed to evaluate the direct flood damage. The DSS evaluates the possible economical damages by integration of hydraulic, hydrologic, topological, and economic database. The hydraulic model, HEC-RAS is used to modeling the flood flow. ArcGIS is used to show flood maps. The floodplain of the Yeouju of Kyunggi-Do, located in South Han River Basin, KOREA, served as research area. The aim of this paper is to identify, determinate and represent direct flood damage caused by various sizes of flood using ArcGis. Overall, the results of the study indicate that DSS using GIS is proven to very useful and efficient for the automatic generation of flood maps, and an effective environment for estimating, mapping, and analysis of economic value of direct flood damage.
