Esp.mp4 - Meander 2019
The water moves slower, leading to the deposition of sediment (sand, gravel) and the forming of a gently sloping river beach.
Here is a proper summary of the processes depicted in such a simulation: Meander 2019 esp.mp4
The experiment confirms that meanders are often initiated by disturbances in the channel (e.g., obstacles or bank variations). The water moves slower, leading to the deposition
