| 摘 要： | 利用平面二维潮流方程结合悬沙输运方程模拟了河口最大浑浊带现象。并且对河口边界进行进一步概化 ,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的平面分布特点。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的悬沙富集有重要贡献。

| Abstract: | A two dimensional vertically averaged hydrodynamics sediment transport model is developed to reproduce a number of key features of estuarine turbidity maximum zone.Assuming an equilibrium between the net upward and downward sediment transports,the common advection diffusion model is used to simulate the suspended sediment transport under the conditions of steady current and non steady current,steady sediment source and non steady sediment source, and a rectangle estuary and a linear expanding estuary.The results suggest that non steady current and boundary conditions are important to producing the estuarine turbidity maximum zone. |
