Abstract
Typhoon is the most serious natural disaster in Korean coastal area. Many peoples died by storm surge inundation every year. Andtyphoon caused a lot of damage to property. Climate changes due to global warming are producing a stronger natural disaster. Coastalzones have been damaged by typhoons and accompanying storm surge. Especially, the most serious loss of life and terrible propertydamage caused by typhoon Maemi in 2003. After then, there has been an increased interest in these coastal zone problems. If stormsurges coincide with high tides, the loss of life and property damage due to high waters arc even worse. Therefore it is desirable toaccurately forecast the amount water level increase.In this study, using a numerical model FVCOM(finite volume coastal circulation model, Chen et al.,2004), storm surge was simulatedto examine its fluctuation characteristics for the coastal area behind Masan, Yeosu and Busan city in Korea. In the numerical model, amoving boundary condition(wet-dry treatment) was incorporated to explain wave inundation. Numerically predicted inundationregimes and depths were compared with measurements from a tidal gage each area. Comparisons of the numerical results andmeasured data shows a good correlation. The numerical model adopted in this study is expected to be a useful tool for analysis ofstorm surges, and for predicting inundation regimes due to c
