河口最大浑浊带平面二维数值模型

2-Dimensional Numerical Model for Estuarine Turbidity Maximun Zone

利用平面二维数值模型模拟河口最大浑浊带现象。在概化河口的基础上，比较了恒定流与非恒定流、稳定源与非稳定源、矩形河口与线性河口等不同条件下河口悬沙浓度平面分布特点，并在黄茅海河口进一步得到验证。结果表明，河口地形边界和非恒定潮流作用对河口最大浑浊带悬沙富集有重要贡献。

Phenomenon of estuarine turbidity maximum zone is modeled by 2-dimensional numerical model. Based on regularized outlet catiparison has been carried out for characteristics of distribution of suspended sediment concentration in plane at the estuary under conditions of both steady and non-steady flows, steady and non-steady sources and rectangular and linear estuaries. The results have been proved in Huangrnaohai Outlet. The results show that topographic boundary of etstuary and action of non-steady tidal current contribute significantly to the concentration of suspended serlirnent in estuarine turbidity maximum zone.
