홍수터 관리를 위한 홍수직접피해 공간분석

다국어 초록 (Multilingual Abstract)

The main damages by several recent flood events in Korea are responsible for steep increase of direct flood damage, and the scale and coot of damages. Many studies are actively in progress to evaluate the possible economical damages
and long-standing problem Assignment of graphical development has received considerable attention. The integration of topographical, hydrological, hydraulic and economic information in flood damage simulation makes it possible to determine the total impact of floods by means of stage damage curves and Geographic Information Systems (GIS). This methodology is applied to a Yeoju-gun. of Gyeonggi-Do located in South Han River Basin of South Korea. The study describes the procedure to identify, determine and represent direct flood damage caused by various-size of design floods using HEC-RAS and ArcGIS. Especially, ArcGIS is used for mapping and analyzing economic value of damages with 2D and 3D graphic capabilities. Overall, the results of this study indicate that GIS is useful and efficient for the
automatic generation of flood maps, and an effective environment for estimating, mapping, and analyzing economic value of direct flood damage.
