Abstract：In this paper,a storm surge and wave coupled inundation simulation model at high resolution was established based on the ADCIRC(a parallel advanced circulation model for oceanic,coastal and es-tuarine waters)and the SWAN(simulating waves nearshore)ocean numerical models,which was ap-plied for the simulation and calculation of the typhoon-induced storm surge in Wenchang.Based on Ty-phoon Kalmaegi(No.1415),a series of paths were designed to perform sensitivity analysis of landing location.The results showed that the landing location had a significant impact on the storm surge.We also designed different intensity path sets to calculate the storm surge and perform hazard assessment.The results showed that the stronger the typhoon intensity,the larger the submerged range,the deeper the submerged depth,and the larger high-risk area.With the decrease of typhoon intensity,the sub-merged area gradually decreased.However,due to the low terrain of Bamen bay and Puqian bay,under the intensity of 990 hPa,there was still more than 1.2 m submerged depth,which was easily sub-merged.It is a vulnerable area and needs more attention and prevention.
