Abstract

Recently, quasi 3-Dimensinal (Q3D) ocean models have been utilized for coastal inundation simulations. However, the Q3D models require large computational effort, and are not suitable for large-scale inundation simulation with fine grid resolutions. The main purpose of this study is to develop a Q3D-H2D coupled model, which consists of a quasi-three-dimensional ocean model CCM (Q3D model) and a horizontal two-dimensional inundation model using a CIP method (H2D model), in order to analyze storm surge-induced inundation with efficiency and low computational load. The validity of the coupled model was verified by comparing with the existing numerical results and the experimental ones. As a result, the coupled model was confirmed to be consistent with the existing numerical schemes. Furthermore, the numerical results were found to be in good agreement with the experimental ones, which indicated that the coupled model was capable of analyzing inundation with high accuracy.
