英文摘要	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 how. 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. Since the stable transportation of sediment by hyperconcentrated flow is dependent on river channel boundary conditions, the latter play an important role in the formation of meanders of this kind. The paper also discusses the conditions for the discrimination of meandering and braided rivers in this area.
