Abstract: Abstract Using an ADCIRC model with 26 coastal sea walls and assuming that not all coastal sea walls are damaged during a storm surge, we simulated the county of Yuhuan’s maximum possible inundation depth and performed a hazard assessment. Additionally, we assessed the vulnerability of Yuhuan County based on land use. Then, based on these assessments, we evaluated the overall storm surge risk for Yuhuan County. The results show that Yuhuan County can be divided into three areas. The first area includes the town of Shamen, the Damaiyu sub-district, etc., and is occupied by people and typically an active area. Although the hazard grade of a part of this area is not high, its risk grade is significant, and most areas belong to the extremely high-risk grade. The second area consists of the sea walls of Jiaomen, Puzhu, Xiaopuzhu-Xitan, Taiping, etc., and includes bare lands, farmlands, shoals, small villages and storage areas. Although the hazard grade for this area is extremely high hazard or high hazard, its risk grade is moderate risk. The third area includes the remaining area in Yuhuan County, where there is no submerged area; this area includes low-lying areas but also has two layers of sea walls. In this area, the surroundings of Xuanmen Bay are only partially used for aquaculture.
