Abstract

Estimation of wave height is the most important factor in the design of coastal structures such as breakwaters. In the present study, typhoon wind distribution was constructed by applying the parametric model of Holland (1980), and numerical simulations on the typhoon-generated waves were carried out using the WAM. The typhoons which affected the southern coast of the Korean Peninsula and several hypothetical typhoons were selected to construct the training sets. Design wave heights were estimated using the empirical simulation technique for various return periods and wave directions. The estimated design wave heights were compared with those by the peaks-over-threshold method and the results of KORDI(2005).

방파제 등 항만 외곽시설의 설계에 있어서 파랑은 구조물의 단면을 결정하는 가장 중요한 요소이다. 본 연구에서는 Holland(1980)의 파라미터 모델을 이용하여 태풍시의 해상풍을 구축하고, WAM 모형을 이용하여 태풍에 의한 파랑을 수치 계산하였다. 남해안의 부산, 목포, 여수, 서귀포 지역에 영향을 미친 태풍을 선정하고 가상의 태풍을 추가하여 training set을 구성하고, 남향 계열의 7개 파향에 대해서 경험모의기법을 적용하여 재현기간별 설계 파고를 산정하였다. 또한, 이를 POT 방법과 한국해양연구원(2005)의 결과와 비교, 분석하였다.
