Numerical research on effects of mean sea level on storm surge inundation in Huanghua

Based on the risk assessment model for the storm surge flood disaster in Huanghua of Hebei Province,with robust typhoon storm surge numerical model and 100m spatial resolution storm surge overland numerical model,and with the result data about mean sea level rising and land subside,the author calculated all possible routes,landing points,and direction of typhoon,and also considered 4 levels typhoon strength,including P0= 995 hPa,985 hPa,975 hPa and 965 hPa,and finally concluded with the effects of mean sea level on storm surge flooding area.The results show,if sea level rising 50/100cm,the average typhoon storm surge flooding area would increase about 35%/86%.And while P0=985 hPa or 975 Pa,the increasing area would become larger in percentage.The research indicates that the sea level rising will affect severely on the typhoon storm surge inundation in Huanghua.Nowadays,the climate change causing sea level rising will lead to some important attention on these low plain areas such as Huanghua and its adjacent Tianjin Binhai New District.
