一方面将波浪对底部剪切应力、表面拖曳力系数,辐射应力以及表面混合长度的影响引入至COHERENS.另一方面又将水动力模型COHERENS和第三代波浪模型SWAN耦合,使两模型能够随时互相交换水流、水位以及波浪信息,最终获得波流耦合模型COHERENS-SWAN并将其应用于荣喜近岸区波流共同存在情况下的波流作用模拟研究.计算所得的流速、流向和水位与实测数据吻合较好.

Wave-tide induced longshore current in Rongxi area will be discussed in the potential paper. A hydrodynamic model COHERENS is coupled with the third generation wave model SWAN. Inside COHERENS, SWAN is regarded as a subroutine and it gets time- and space-varying current velocity and surface elevation from COHERENS. COHERENS gets time- and space-varying wave relevant parameters calculated by SWAN. Wave-enhanced bottom stress, wave dependent surface drag coefficient and radiation stress are introduced to COHERENS. Then a fully coupled hydrodynamic-wave model OHERENS-SWAN accounting for interaction between wave and current is obtained and adopted to simulate longshore current in Rongxi area. Generally, the values of time series of current velocity, current direction and water level have a good agreement with the observed data.
