Abstract
Typhoon-induced storm surges can cause severe damage on the Korean peninsula, where typhoons typically occur two or three times per year with 80 % of the total typhoons occurring during summer. In the case of the 14th typhoon MAEMI (0314) in 2013, a storm surge of 2.1 m was observed at the southern coast of the Korean peninsula, and the total property damage was USD 4.3 billion along with 132 casualties. In the case of 16th typhoon CHABA (1618) in 2016, a storm surge of 1.1 m was observed at the southern coast of the Korean peninsula, and the total property damage was USD 18.3 million along with seven casualties. Therefore, accurate prediction of storm surge heights and peak durations of typhoon surges occurring in the vicinity of the Korean peninsula is important for minimizing this damage. Therefore, in this study, storm surge numerical experiments were performed using the Delft3D model with the typhoon parameter model results as weather field input data. The experimental results matched well with the recorded observations at the weather stations considered in this study. Moreover, the experimental results showed that as the typhoon moves faster, the peak duration becomes shorter, and the maximum surge height decreases or increases depending on the local geography.
