| 摘 要： | 通过建立一个三维陆架海数值模式来预报近海潮流和泥沙浓度的对流扩散,并应用于琼州海峡跨海工程的前期数值预测。预测结果表明,海区潮流的涨落、岸线形状、海底地形及源强位置与泥沙在近海的输运扩散关系密切,模拟情形基本合理,表明该模式适合应用于河口、近岸等涉海海洋工程海域的流场及泥沙扩散的三维数值预测,为相关的水动力环境要素和水质影响评价提供一定的参考价值。

| Abstract: | A three-dimensional shelf sea model is set up to forecast the tidal current and the sand advection and diffusion in nearshore zone,and applied to the pre-forecasting of the engineering across the Qiongzhou Channel.The results show that the sand transport and diffusion has close relationships with the flood and ebb of tide,the shape of coastal line,the bottom topography and the sand source position,which are basically reasonable,indicating that this model is fit for three-dimensional numerical forecasting of current field and sand diffusion of ocean engineering in estuarine and nearshore zones,and is useful for the impact evaluation of hydrodynamic environmental parameters and water quality. |
