슈퍼 태풍 하이옌(Haiyan) 내습에 따른 필리핀 해역에서의 폭풍해일 및 파랑 수치 모의

Abstract

Super typhoon Haiyan made landfall in the Leyte island, Philippines and devastated the areas located near the typhoon passage on 8 November 2013. Its maximum sustained 1 minute surface wind speed was reported about 315km/h, which is recorded to strongest Category 5 hurricane and super typhoon. This was one of the strongest historical storm event in the world, killing at least 6,268 people in the Philippines. Large loss of life was occurred from inundation of low-lying areas by storm surge and waves. In particular, there was widespread devastation by a high storm surge in Tacloban city. In this study, the impacts of storm surge and waves were investigated after numerical simulation using the unstructured grid model, FVCOM and SWAVE. The simulated results reasonably represented reported surge height. Estimated surge and wave height were shown approximately 3.9m and 1.6m in the Tacloban city. However, further detail model validation is still needed using additional observation data.
