基　　金：The Natural Science Foundation Study on Mechanics of Non-breaking wave-induced vertical mixing on Pollutant Dispersion of Huanghe River Estuary under contract No.51179178;Project from Establishment of Fine Sediment Transport Modeling System for the Yellow Sea;which is a sub-project of Development of Operational Oceanographic system;Science & Technology Development Project of Qingdao under contract No.09-1-3-18-jch 摘　　要：A three-dimensional wave radiation stress is introduced into the hydrodynamic sediment coupled model COHERENS-SED,which has been developed through introducing wave-enhanced bottom shear stress,wave dependent surface drag coefficient,wave-induced surface mixing,SWAN,damping function of sediment on turbulence,sediment model and depth-dependent wave radiation stress to COHERENS.The COHERENS-SED is adopted to study the effects induced by wave-induced three-dimensional longshore current on suspended sediment spreading of the Huanghe River (Yellow River) mouth.Several different cases divided by setting different wave parameters of inputting boundary waves are carried out.The modeling results agree with measurement data.In terms of simulation results,it is easy to know that three-dimensional wave radiation stress plays an obvious role when inputting boundary wave height is stronger than 3 m.Moreover,wave direction also affects the sediment spreading rules of the mouth strongly too. 关键词：泥沙模型黄河口沿岸流立体数值研究波浪传播辐射应力
