Meanders caused by hyperconcentrated water flow: an example from the Loess Plateau, China

Auteur :
XU JIONGXIN,

Description :
This paper describes meandering alluvial rivers with mean annual suspended-sediment concentrations of more than 100 kg m-3 on the Loess Plateau, China, and explains their formation as caused by the effect of hyperconcentrated water flow. When the river is dominated by hyperconcentrated flow, the rate of energy expenditure required for sediment transport declines significantly. Accordingly, the river channel adjusts itself to a lower channel gradient by increasing the river length, resulting in a meandering channel. The paper also discusses the conditions for the discriminations of meandering and braided rivers in this area.
