本文主要研究内容
作者王辰(2019)在《舟山渔港台风暴潮—波浪耦合模拟及分析》一文中研究指出:舟山渔港是国家级中心渔港,附近海域渔业资源丰富,但台风引起的风暴潮和波浪对其安全造成了严重威胁。研究舟山渔港台风暴潮和台风浪的时空分布及两者间的相互影响,对海洋防灾减灾具有重要意义。基于Delft3D的Flow和Wave模块,在同心圆正交网格下建立了适用于舟山渔港的台风暴潮-波浪耦合模型,模拟的潮位、流速和有效波高均与实测值符合良好。与非耦合模型相比,耦合模型能更好地模拟台风暴潮和波浪,风暴潮位模拟精度可提高26cm,最大波高精度可提高8.63%。耦合模拟了 9711台风期舟山渔港的风暴潮和波浪过程。结果显示,港区最大风暴潮增水和最高潮位分别发生在第65时和第70时,最大增水1.283 m,最高潮位3.151 m。增水和潮位自东南向西北递增,增水南岸大于北岸,潮位在横向上变化不大。涨急时刻,最大风暴潮流速达0.575m/s,台风引起的流速最大增值为0.269m/s,增速效应向西北沿程递增。落急时刻,最大风暴潮流速0.228m/s,台风造成的流速减小值可达0.189m/s,风暴潮流速向东南先减后增,减速效应恰好相反。台风第72时渔港波高最大,为1.104m,出现于V区。自区域Ⅰ至V波高先减后增,北岸波高总体大于南岸。9711台风期渔港内风暴潮与波浪相互影响的数值试验表明,浪潮耦合作用在风暴潮和波浪模拟中不可忽视。第65时港区波浪引起的水位增值最大,对风暴潮增水的贡献率变化于19.8%~25.9%。第70时风暴潮位最高,水深较大,波浪对风暴潮增水的贡献率小于10%。波浪使涨急流速减小,落急流速Ⅰ至Ⅳ区增大、V区减小,对流向影响总体不明显。第72时风暴潮对波高的影响最明显,风暴潮位使波高增加,最大增值达0.258m。风暴潮流使波高Ⅰ至Ⅲ区增加、Ⅳ至V区减小,对波高增值的贡献率明显小于风暴潮位。
