| 摘 要： | 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。研究沙波的运动规律对研究泥沙运动、河床演变和河道整治具有十分重要的意义。本文对国内外有关水槽与天然河道实测顺行沙波资料进行了分析研究,提出了计算沙波波高及波速和推移质单宽输沙率的公式。

| Abstract: | Sand wave movement is an important form of sediment movement for alluvial rivers and has a great effect on stream resistance. The research of sand wave movement is of great significance to the study of sediment movement and fluvial processes and river regulation. Based on investigation and analysis of sand wave data from the flumes and rivers both abroad and at home, the formulae for the height and velocity of sand wave and the bed load rate are obtained in this paper. |
