유한체적모형을 이용한 파랑-흐름 복합모형에 의한 폭풍해일고 산출 모의

Abstract

Typhoon-induced storm surge, waves, andcoastal inundation in the western and southerncoast of Korea region are simulated using finemesh unstructured grid model FVCOM(anunstructured-grid Finite-Volume Coastal OceanModel) coupled to a coastal wave model SWAN.The reanalysis 10-m wind and air pressure data areproduced by WRF and a relatively simpleanalytical wind model are used on Typhoon wind.The wave-current couple procedure includes depthdependent wave radiation stress terms, Stokes drift,vertical transfer of wave-generated pressuretransfer to the mean momentum equation, wavedissipation as a source term in the turbulencekinetic energy equation, and mean currentadvection and refraction of wave energy.
