Landslide caused by reservoir impoundment

After the reservoir is impounded, due to the fluctuation of water level or the action of wind and waves, the bank slope of the reservoir is constantly eroded and washed away, so that the bank slope near the water surface is hollowed out and the upper rock and soil loses support, and bank slope landslide will occur.
