Choi, H.; Lee, H.J., and Kim, G., 2019. Damage analysis of typhoon surge flood in coastal urban areas using GIS and ADCIRC. In: Lee, J.L.; Yoon, J.-S.; Cho, W.C.; Muin, M., and Lee, J. (eds.), The 3rd International Water Safety Symposium. Journal of Coastal Research, Special Issue No. 91, pp. 381-385. Coconut Creek (Florida), ISSN 0749-0208. Typhoon Maemi, which landed in the coastal area of Masan City on September 12, 2003, was the largest coastal disaster in Korea. Typhoon surges can cause extreme flood damage when they overlap with high tides. In this study, the maximum flooding zone according to the highest tide was calculated and the accuracy of the flooding model was analyzed by comparing it with the actual flooding zone in the Masan Bay area. A GIS-based hydrologic model for flood forecasting can complement the disadvantages of complex multidimensional flood damage estimation in which data acquisition and processing are complicated. It is important to establish a method to minimize damage by developing a more accurate damage simulation model. It is necessary to utilize data such as high-resolution satellite images and LiDAR for accurate analysis data considering the topographical characteristics of typhoon surge flood areas in the future.
