Abstract

This paper presents the numerical simulation of storm surges including wave-current interactions based on the 3D nearshore current model. Newly developed numerical model included new terms on surface stress and wave-induced Reynolds stress. The present nearshore current model calculates nearshore current field under storm surge, the wave forcing terms should be provided by the additional computation on the waves and surface roller. For the wave-current interactions, the present model is dynamically coupled with wind wave model which is modified WAM applicable to shallow water. We conducted storm surge simulations in Youngil-bay located in the east coast of the Republic of Korea. One of the purpose of this simulation is to estimate the influence of large breakwater constructed in the north side of bay entrance on the erosion of beaches located inside bay area during the storm.
