| 摘 要： | 感潮河段的水流、泥沙运动有其独特的性质。本文针对其特点 ,水流的挟沙力由水动力因素、泥沙因素共同决定 ,以此建立非均匀悬沙的二维数学模式。模式用于模拟长江口感潮河段的悬沙含量的分布和变化 ,计算的结果与 1996年 9月实测资料拟合的较好 ,并在此基础上分析了感潮河段流速、含沙量与水流挟沙力的确定之间的关系。

| Abstract: | According to the characteristics of hydraulic and sediment transportation in the tide effected channel,a two\|dimension non\|uniform suspended sediment model is developed in this paper.In the model, the carrying capacity is calculated by sediment and hydraulic factors.The suspended sediment concentration in tidal effected channel of the Yangtze Estuary is simulated.The calculated result shows a good agreement with measured data of flood period in 1996.Further,the relations among the velocity, sediment concentration, and carrying capacity are discussed. |
