江苏海域波浪数值模拟研究
|
摘要
本文以风场为驱动运用第三代波浪模型SWAN对江苏海域的波候进行了模拟研究。在模拟过程中采用了嵌套结构,并考虑了潮位对波浪的影响,提高了近岸波浪模拟的精度。同时,对江苏海域波浪分布特征进行了研究。研究结果表明:江苏海域深水区域年平均有效波高分布趋势由南往北逐渐递减,而近岸10m水深处波高从大丰港开始由南往北呈先增加后减小的趋势。江苏海域年平均有效波高最大值为1.5m,最大年平均周期为4.6s,常浪向为NE或SE方向,四季中冬季浪最大,强浪向为NE—NNE方向。
The wave condition of Jiangsu sea area with Delft 3D model is studied in the paper,which was driven by wind filed.And the influence of tidal current was taken into the model.The model result was more accurate than before.Then,wave condition of Jiangsu sea area was analyzed.The result shows that:the annual average wave height became smaller from southeast to northwest in deepwater,and the largest annual average wave height was around 1.5 m.Most waves came from direction NE and SE in this area.
