| 摘 要： | 将三维水动力-生态模式COHERENS与第三代波浪模式SWAN结合起来,采用该耦合模式数值计算了黄河三角洲的波浪特征波高与特征周期情况,从而探讨水流和波动水位对波浪特征波高和特征周期计算结果的影响。总的说来特征波高、特征周期、流速的计算结果与观测值吻合得较好,说明了COHERENS模式和SWAN模式相结合而成的波流耦合模式能够较好地计算黄河三角洲地区的流场与浪场情况。研究这些动力因素的机制和时空变化规律,对于研究海岸、河口的泥沙运动,海岸侵蚀的机理,合理开发利用自然资源,防止海洋灾害具有十分重大的意义。

| Abstract: | There are obvious functions of wave-current coupling in coastal and estuarine zones, so it is recommended strongly to account for such interaction when wave or current is simulated. In the present work, three-dimensional hydrodynamic model COHERENS is coupled with the third generation wave model SWAN. The obtained model by combining COHERENS and SWAN is named as COHERENS-SWAN and it is used to simulate wave and current in the Yellow River Delta. The effects of current and water level on wave are discussed. There are good agreements with measurement for significant wave height and significant wave period generally, which demonstrates the effectiveness of COHERENS-SWAN in the simulation of wave and current in the Yellow River Delta. |
