【摘要】 本文提出了一个讨论近岸波浪和波生流耦合作用的二维数学模型。在波浪场中运用波数矢量无旋和波作用量守恒方程求解波浪在波生流作用下的折射、绕射变形，以辐射应力作为波生流场的驱动力，考虑地转柯氏力和海底底摩擦的作用。文中采用Dingemans（1987）的地形对波流耦合作用进行了分析。数值计算结果表明波流耦合作用对近岸波浪场和波生流场的影响比较显著，在工程实际上应当综合考虑波流耦合问题。更多还原

【Abstract】 A 2-dimensional coupling model is presented in this paper for studying near-shore waves and wave-induced currents in nearshore region. In the model, theirrotationality of wave number vector and the wave action conservation equationare employed to deal with the wave refraction and diffraction under the effect ofcurrents. Radiation stress due to wave motion is adopted as the driving force forwave-induced currents, with the Coriolis force and seabed friction taken int0account. Waves and wave-induced currents are coupled with current velocity U Vand water elevationξ. A topography with cos2 protuberances presented by Dinge-mans (1987) is used as an example to illustrate the coupling effect of waves andwave-induced currents. The numerical results show that the coupling effect ofwaves and wave-induced currents is notable and should be considered comprehen-sively in coastal engineering.更多还原
