摘要：基于ADCIRC模型建立了徐闻高分辨率的风暴潮模型，并以1415号台风"海鸥"路径为基础，通过路径平移构建了一系列台风路径，模拟计算了徐闻沿海风暴增水。结果表明：徐闻东部沿岸的风暴增水最大，主要原因在于东部沿岸的独特地形特征以及该区域受到的有利台风路径影响。在上述工作的基础上，耦合海浪和天文潮的作用，计算10个不同等级下徐闻风暴潮淹没情况，计算结果显示，徐闻东部沿岸的风暴潮淹没灾害大于南部和西部沿岸。

Abstract：Based on ADCIRC model, a high-resolution model is established to simulate the coastal storm surge along the Xuwen using a series of typhoon tracks conducted through track translation of typhoon "Kalmaegi" (1415).The results show that the maximum storm surge is along the eastern coast of Xuwen, which is mainly due to the unique topography and the favorable typhoon tracks in the area. On the basis of the above work, the storm surge inundation conditions of Xuwen under 10 different levels of minimum air pressure are calculated by coupling the effect of ocean wave and astronomical tides, which reveals that the storm surge inundation disaster along the eastern coast of Xuwen is more serious than that along the southern and western coast.

Key words：ADCIRC model; storm surge; coupling; inundation
