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

Based on both shear force and stream power and through theoretical derivation, the incipient motion critical conditions of cohesionless uniform sediment are achieved.
通过理论推导，得出基于剪切力和水流功率的均匀沙起动临界条件表达式。
3
The main channel bed will scour if sediment amount from tributary debris is less than that the main stream can carry and the river evolution exhibits the characteristic of mountainous rivers.
