中文摘要：裂流是海滩旅游中重要的安全隐患,国内目前还很少有裂流风险的评价研究。文章基于地形动力学模型对湛江东海岛海滩裂流风险从年平均、逐月平均和逐月常浪向状况下进行了评价。结果表明:(1)东海岛海滩全年平均状态为沙坝消散型海滩,一年四季出现裂流的概率较大,为中等危险性的海滩;(2)逐月平均海滩类型以沙坝消散型为主,但在6—7月海滩类型为低潮沙坝/裂流型,海滩风险等级最高,8月的月平均海滩状态为无沙坝消散型,属于危险性较低海滩,但此时波浪向为SE向时,海滩状态变成低潮沙坝/裂流型,裂流风险等级很高;(3)海滩管理者要重视对海滩裂流风险的管理。

外文摘要：Rip current is a major risk in beach tourism.Few studies have been done on the rip current risk in China.In this paper,the rip current risk at the Donghai Island beach,Zhanjiang,was evaluated based on the morphodynamic model.Results showed that:(1)The beach of Donghai Island has a barred dissipative beach state at annual scale.The beach has a medium risk of rip current occurrence;(2)The monthly average beach state is mainly barred dissipative beach state.But in June and July,beach states are low tide bar/rip states,which have highest rip current risk.In August,the monthly average beach state is non-barred dissipative and the beach is safety.The beach will be transformed into the low tide bar/rip state when the waves come from the SE direction and the rip current risk level become high in August;(3)Beach managers should pay more attention to the rip current risk.
