| 摘 要： | 基于河口海岸水动力二维数值模型,建立风暴潮与天文潮耦合作用的数值模式,通过三次强台风和二次超强台风引起的风暴潮增水模拟和分析,证实该模式可用于浙江沿海增水预测.以1949年以来登陆我国大陆沿海最强的"5612"号台风作为典型的超强台风,利用本模式计算分析了超强台风在浙北至浙南5个不同地点登陆遭遇大潮时可能出现的风暴潮增水过程和最大增水,该结果对于海岸工程的防护具有实际的意义. |

| Abstract: | A numerical model of the coupling between astronomical tide and storm surge based on a 2D hydraulic model for estuary and coast(Mike 21) is confirmed to be suitable for prediction of storm surge in coastal regions of Zhejiang Province by simulation of storm surge caused by 3 strong typhoons and 2 super typhoons,that landed in the Province.Typhoon No.5612,the most intense in China since 1949,is taken as the typical super typhoon for the design of 5 typhoon routes,each landing at a different location along the coast from north to south.The storm surge process and possible maximum value along the coast are calculated by the model under the conditions of 5 designed typhoons coinciding with the spring tide when they land.The results are of practical significance for protection of coastal engineering during super typhoons. |
