Short summary
This paper describes the case of a meandering bedrock river with loose sediment on the bed. In such rivers, the sediment hits and erodes the bed as it moves with the flow. We did experiments in a laboratory flume to identify the areas where the sediment moves and those where it deposits. We discovered that the size and location of those areas change with the amount of sediment in the channel and its curvature. The fluctuations of sediment cover over the bed drive the erosion potential.
