河流泥沙运动

沙波运动是冲积河流泥沙运动的一种重要形式。沙波的消长对河道水流的阻力损失有很大的影响。

Sand wave movement is an important form of sediment movement for alluvial rivers and has a great effect on stream resistance .

冲积河流阻力是泥沙运动力学中的一个重要问题。

Alluvial channel resistance is one of the most important issues in sediment transport mechanics .

针对平原细沙河流泥沙这一运动特点，提出了一种模拟平面细沙河流的相似准则和设计方法。

For this , similarity criteria and design methods for plain sand-bed rivers are presented .

河流悬移质泥沙运动模拟方法研究

A Study on Simulating Methods of River Suspending Sediment Movement

在我国，许多河流都是多沙河流，河流中泥沙的运动，既关系到河流本身的发展与演变，也影响着重大水利工程建设的成败。

In our country , There are much send in the rivers . The movement of sediment not only has something to do with the development and evolution of rivers themselves but also influences the success of the hydraulic engineering projects .
