Abstract: Taking the coastal area of ​​Huanghua City as the research object, the ADCIRC model is used to establish a typhoon and temperate storm tide beach numerical model to evaluate the danger of storm waves under different working conditions. Disaster risk assessment and regional research. The results show that: under the influence of the 965 HPA and 955 HPA -level typhoon storm waves and wind storms of 32 m/s and 36 m/s, the coastal towns and towns are damaged to varying degrees, and the risk of temperate storm is greater than that of typhoons. Essence The high -risk zone of Huanghua City is mainly distributed in Nanpaihe Town, Xincun Hui Township and Huanghua Port. The highest risk -up condition is the tide of temperate storm (36 m/s). The area of ​​the storm trend risk zone under this condition is 1 184.54 km2. It is the lowest risk of other townships in Nanpaihe Town, Luqiao Town, Yang Sanmu Hui Township, Zhongjie Friendship Farm and Nanda Port Farm.

Abstract：Taking the coastal area of ​​Huanghua City as the research object, the ADCIRC model is used to establish a typhoon and extratropical storm surge inundation numerical model, and to evaluate the risk of storm surge disaster under different working conditions. Combined with the vulnerability analysis of disaster-bearing body, the risk assessment and zoning research of storm surge disaster is carried out in this paper. The risk assessment results show that under the influence of typhoon storm surge with the level of 965 hPa and 955 hPa and extratropical storm surges with wind speeds of 32 m/s and 36 m/s, coastal towns are damaged to varying degrees, and the risk of extratropical storm surges is greater than that of typhoon storm surges. The high-risk areas in Huanghua City are mainly distributed in Nanpaihe Town, Xincun Hu Ethnic Township, and Huanghu Port. The Working Condition with The Highest Risk is the Dyke Break Cautropical Surge With the level OF 12 m/s angel d 36 m/s. Under that condition, the storm risk area is 1 184.54 km2, of which Huanghua Port and Xincun Hui Ethnic Township have the largest risk area of ​​level I, followed by Nanpaihe Town, Luqiao Town, Yangsanmu Hui Township, Zhongjie Friendship Farm, NANDAGANG FARM, While The Other Townships Have Lower Risk.key Words: Storm Surge Disaster; Risk; Vulnerability; Risk Assessment; Zoning; HuangHuaa City;
