黄河河口海岸二维非恒定水流泥沙数学模型

2-D numerical model for unsteady flow and sediment transport in Yellow River estuary

针对黄河河口海岸岸线变化剧烈和含沙量变幅大的特点 ,开发和建立了适合黄河河口海岸应用的平面二维动边界非恒定水流泥沙数学模型 .验证表明 ,本模型可以较好地模拟黄河河口海岸泥沙输移和冲淤变化 。

In consideration of the rapid migration of coastline and great variation of sediment concentration in Yellow River estuary, a 2\|D numerical model for unsteady flow and sediment transport is developed. Verification demonstrates that the model can effectively simulate the sediment transport, scouring and silting of seabed and the variation of coastline.
