摘要
利用三维潮流数学模型模拟黄骅港附近海域的流场,分析了黄骅港建港前后海域潮流场的主要变化,以及建筑物引起的沿堤流和口门横流及其对泥沙运动的作用.在NE向8级风作用下,黄骅港附近海域水流的垂向流速变化非常显著,对泥沙输移起重要作用.
The velocity field in the sea waters around the Huanghua Harbor is simulated by using the threedimensional tidal current model, variations of the velocity field of tidal current before and after construction of the Huanghua Harbor are analyzed, and the phenomena of the current along the breakwaters, the current across the entrance channel and its action on the sediment transportation are presented. Analysis results show that the flow＇s vertical velocity varies notably and will play an important role in sediment transportation under the action of northeast wind of Scale 8 nearby the Huanghua Harbor sea water.
