估算河道推移质输沙量的数学模型

Numerical method for estimating the quantity of bedload transport in river

本文首次提出了利用数学模型估算河道推移质输沙量，建立了一个恒定非平衡推移质泥沙数学模型，并利用水槽试验成果对之进行了验证．通过实例研究证明，用本文提出的方法估算河道推移质输沙量是可行的．

In this paper a new method is proposed that the quantity of the bedload transport is estimated by using the methematical model of sediment transport. A numerical model for nonequilibrium bedload transport by steady flows is estalished. A set of experimental data in flume is used to calibrate the model and a practical example is investigated in order to verify the feasibility of the new method.
