Risk assessment on storm surge in the Haikou Bay

Based on the flood loss evaluation method,the storm surge risk loss evaluation model of Haikou Bay is set up in this paper,with which,the storm surge risk district of Haikou Bay is analyzed.Possible submer gedareas are also analyzed according to the maximum hightidal level,the combination of strongest storm surge and highest astrono mical tide within 100 a scale.In addition,buildings and population in the submerged regions are statistically counted.Social and economic data are also analyzed in the paper.After introducing the methods of loss rate calculation,loss rates of private property,national collective property,crop and sea farming are estimated as 30%,4%,70%,100% separately.Taking social economic data in 2001 as the baseline,in the case of maximum high tidal level within 100 a scale,the economic loss caused by the storm surge is 832 million RM B,while the loss of private property,national collective property,crop and sea farming,monetary loss of death,indirect loss respectively is 13.0%,70.0%,0.7%,0.8%,15.5%.
