利用Delft3D数值模式建立了洋浦海域二维嵌套水沙数学模型,在对模型进行了验证基础上,模拟了海花岛实施前后海床冲淤演变和潮流变化。由于洋浦海域含沙量较低,附近沙源少,海花岛实施后附近海域海床淤积幅度较小。由于小铲礁南侧水流动力增加,小铲礁南侧和洋浦航道局部为冲刷。

Delft3D is used to set up a two dimensional nested hydrodynamic and sediment model for Yangpu waters in this paper, and this paper focuses on simulating the velocity and morphological change due to the construction of Haihua Island after the verification of the model. The seabed deposition is small because of low suspended sediment concentration and less sand source near Yangpu waters. The bed level erodes in the south area of Xiaochanjiao and the Yangpu channel due to the velocity increase in the area.
