Abstract

A standard typhoon, which results in extreme wind speeds having various return period, can be reconstructed by combination of typhoon parameter informations(Kang et al., 2016). The aim of this study is to present a kind of surge-frequency analysis method by numerical simulation of a standard typhoon at Yeonggwang. MIKE21 was adopted as a numerical model and was proved to simulate the surge phenomena of the typhoon BOLAVEN(1215) well at several sites of the Western Coast. The simulation results with change of typhoon track which reflects typhoon-surge characteristics of the Western Coast show to have something in common with the observational results. This method is considered to be very efficient method on the point of simulating only one typhoon, while existing methods need to simulate a lot of typhoons.

빈도별 최대풍속을 발생시키는 태풍조건을 역추적함으로써 빈도별 표준태풍을 생성할 수 있다(Kang et al., 2016). 본 연구에서는 이렇게 얻어진 표준태풍의 해일모의를 통해 서해안 영광지역의 해일고 빈도해석을 수행하는 방안을 제시하고자 한다. 본 연구에 사용된 모형은 MIKE21모형으로서 태풍 BOLAVEN(1215)에 대한 검증 결과 서해안 여러 지역에서 관측결과와 비교적 잘 일치하는 결과를 얻었다. 서해안 태풍해일특성을 감안하여 경로변경을 설정한 후 빈도별 해일고를 구한 결과는 관측치로부터 산정된 결과와 부합하는 결과를 보이고 있다. 이 방법은 관측자료가 충분치 않은 곳에서 수많은 태풍에 의한 해일모의를 수행하는 기존 방법에 비해 빈도별로 한 개의 태풍만을 대상으로 하므로 매우 효율적인 방법이다.
