Why does erosion of a riverbed increase so much during flood times?
During flood times, the volume and velocity of water in a river increase significantly, leading to higher levels of erosion.

Additionally, floodwaters can also introduce new energy sources, such as debris and trees, that can further contribute to erosion.
