Risk assessment of seawater intrusion in the Red River Delta of Vietnam
摘要
Abstract
The Red River Delta(RRD)in Vietnam is highly vulnerable to seawater intrusion,on which the dis-aster risk assessment is essential for effective regional disaster prevention and mitigation.We developed a compre-hensive indicator system for assessing seawater intrusion risks by analyzing the disaster risks and their spatial dis-tribution across the provinces of Hai Phong,Thai Binh,Nam Dinh,and Ninh Binh.Results show that:① The dis-aster risk levels range from 0.35 to 0.67,reflecting a relatively low to relatively high risk level,with a decreasing trend from the southeastern coastal regions to the northwestern inland areas;② The hazard indicators range from 0.22 to 0.53,indicating relatively low to moderate level,with high-risk areas concentrated along the coasts of Nam Dinh,Hai Phong,and Thai Binh;③ The exposure indicators span from 0.20 to 0.87,showing relatively low to high level of exposure,with elevated levels in the eastern coastal regions of Nam Dinh and Ninh Binh;④ The vul-nerability indicators range from 0.50 to 0.79,indicating moderate to relatively high vulnerability,with the highest vulnerability observed in Ninn Binh;⑤ The risk of seawater intrusion disasters is mainly affected by the expos-ure and vulnerability of regional socio-economic systems,to which we shall consider the need for region-specific disaster prevention and mitigation measures.This study provided a critical insight for enhancing disaster resili-ence against seawater intrusion in the RRD.关键词
