摘要：
In this study, the simulation and analysis of the inundation in a coastal urban area according to the storm surge height are carried out using a two-dimensional finite-volume model with a well-balanced scheme. The target coastal urban area considered in this study is a part of the new town of Changwon city, Gyeongnam province, South Korea; this area was extremely damaged by the storm surge generated during the period of Typhoon Maemi in September 2003. For the purpose of the verification of the numerical model applied in this study, the simulated results are compared and analyzed with the temporal storm surge heights observed at the tide station in Masan Bay and inundation traces in an urban area. Moreover, in order to investigate the influence of super-typhoons possible in the future, the results simulated with the storm surge heights, which were 1.25 and 1.5 times higher than those observed during the period of Typhoon Maemi, are compared and analyzed.
