Balance Adjustment of the Gravel-Sand River Downstream Reservoir

Abstract:

In this article, the typical phenomenon of bed armoring was firstly summarized based on both the field and experiment data, and then followed by the analysis on its internal influence on the reformation process to the balance status for the gravel-sand rivers. It was pointed out that this phenomenon is caused by the chosen of the flow, that the finer sediment particles are washed away and the coarser ones are left on the river bed surface. This phenomenon firstly restricts the start of the sediment particles on the bed surface, secondly increases the river bed surface resistance and reduces the flow velocity. The comprehensive effect of these two aspects leads to the final balance status for the gravel-sand river.
