浪潮耦合的舟山渔港台风暴潮数值模拟
|
摘要
建立能精确模拟舟山渔港台风暴潮过程的浪潮耦合模型,对渔港防灾减灾具有重要意义。基于Delft3D中的FLOW和WAVE模块,在二重嵌套网格下建立风暴潮和波浪的耦合模型。以9711号台风Winnie为背景,验证耦合模型的可靠性,结果显示,风速、天文潮潮位、风暴潮潮位和有效波高的计算值与实测值吻合良好。利用风暴潮模型与耦合模型分别计算了舟山海域的风暴潮,分析了波浪对风暴潮潮位的抬升影响,定海和镇海站最大波浪增水分别为23 cm和34 cm,耦合模型的模拟精度要高于风暴潮模型。通过模拟9711号台风期间舟山渔港的风暴潮过程,分析了风暴潮的时空分布特征,并给出了浪潮耦合作用对于风暴潮时空分布的影响。
It is of great significance to establish the coupled model of storm surge and wave which can accurately simulate storm surge of Zhoushan fishing port for prevention and mitigation of disasters. Based on FLOW and WAVE modules of Delft3D, the coupled model was established under the double nested grids. The reliability of the coupled model was verified in the background of Typhoon 9711. The results showed that the calculated values of the wind speed, significant wave height,astronomical tide and storm tide levels were in good agreement with the in-situ observations. The storm surge of Zhoushan sea waters by the storm surge model and coupled model are calculated separately, and the phenomenon that waves uplifted storm tide levels are analyzed. The maximum wave setup of Dinghai and Zhenhai stations were 23 cm and 34 cm respectively, and the simulation precision of the coupled model was higher than that of the storm surge model. By simulating the storm surge process in Zhoushan fishing port during Typhoon 9711, the spatial and temporal distribution characteristics of storm surge were analyzed, and the influence of coupling effect on the spatial and temporal distribution of storm tide was given.
