| 摘 要： | 采用浪流沙耦合模型COHEREN-SED模型进行黄河三角洲的海流三维运动数值模拟。文中将垂向平均的波浪辐射应力与垂向变化的波浪辐射应力引入至COHERENS-SED,通过该模型进行波浪辐射应力影响下的海流场演变数值研究。研究结果显示波浪辐射应力的存在显著改变了水深小于5m的流场。垂向变化的辐射应力则使得其表层波生沿岸流速大于传统的垂向均匀辐射应力引起的波生沿岸流速,底层则刚好相反。当波浪强度很大时,流场中的波生沿岸流对水深较浅的海岸区海流场影响较大。

| Abstract: | Three-dimensional numerical modeling for marine currents in the Yellow River Delth sea-area is conducted by means of the wave-current-sand coupling COHERENS-SED model,into which the depth-independent wave-radiation stress and the depth-dependent one are input respectively to study the stress-effected current variability.It is learnt from the results that the stress imput can obviously change the currents in the depths shallower than 5 m depth.The depth-dependent wave-radiation stress generates the surface w... |
