主　　题：storm surge astronomical tide extreme water level hazard risk 

摘      要：Extreme water levels are related to astronomical tides and storm *** typhoon systems,which have caused extreme water level rises,were selected based on 60-yr water level data from the Xiamen tide gauge *** these 11 typhoon systems,the astronomical tide component accounts for 71%-95%of the total water *** Gumbel distribution of extreme water level rise was estimated,and the impact of typhoon surges on water levels during the return period was *** ex-treme tide levels caused by typhoons Herb(1996)and Dujuan(2015)are much higher than those of other typhoons and correspond to the return period of 76 yr and 71 yr,*** differences of sea levels in the presence and absence of these two typhoons in the 10-100 yr return period are 5.8-11.1 *** the 100-yr return period,the total risks within 10,25,50,and 100 yr increase by 94.3%,85.4%,72.9%,and 54.4%,respectively,if the Herb and Dujuan are not *** that typhoon Herb(1996)occurred during the highest astronomical tide,it will produce a water level higher than that of the 1000-yr return *** level rise has an important influence on the water level return period,and the contribution of nonlinear sea level rise in the next 100 yr is estimated to be 10.34%.
