| 摘 要： | 为了计算波流共同作用下含沙量沿垂线的分布,建立了沿垂线分布的泥沙扩散系数模型。通过悬沙模型反求泥沙扩散系数的方法来拟合系数。实测资料表明该模型可以比较准确地直接计算泥沙扩散系数沿垂线的分布。

| Abstract: | To calculate distribution of sediment concentration in vertical under wave and current,a model of silt diffusion coefficient distribution in vertical is set up.The coefficient is fitted from calculating the sediment diffusion coefficient by suspended load model.It's shown from measured data that the distribution in vertical of sediment diffusion coefficient can be obtained correctly by the model. |
