| 摘 要： | 南汇东滩紧邻长江口主要排沙通道南槽而成为泥沙沉降的一个重要部位,为促淤围垦提供了有利的滩地和来沙条件,是上海市规划围垦的重点区域。目前上海已在南汇东滩开始实施围垦工程,围垦工程改变了长江口南汇岸线,也改变了南汇东滩的水动力条件。为了解围垦工程实施后水动力条件的变化,采用二维潮流数学模型模拟南汇东滩促淤围垦工程实施前后流场的变化,探讨围垦工程对邻近水域水动力产生的影响,为预测圈围工程实施后南汇东滩变化提供水动力学依据。

| Abstract: | Close to the South channel of the Yangtze River estuary, the main channel to transport sediment, the east shore of Nanhui becomes an important position for sediment silting.It has an favorable condition of the shore and sediment supply for reclaiming, and now is a key area in Shanghai reclamation plan.Shanghai has already started a reclamation project on the east shore of Nanhui.The reclamation will move the sea line, which can bring about the change of the hydrodynamic condition.A 2-D tidal flow mathematics model is set up to predict the change and discuss the influence of the project on the water area sur- rounded. |
