Types of erosion. The energy in a river causes erosion. The bed and banks can be eroded making it wider, deeper and longer. Headward erosion makes a river longer. This erosion happens near its source. Surface run-off and throughflow cause erosion at the point where the water enters the valley head. Vertical erosion makes a river channel deeper.

Bank erosion - Wikipedia

Bank erosion is a natural process: without it, rivers would not meander and change course. However, land management patterns that change the hydrograph and/or vegetation cover can act to increase or decrease channel migration rates. In many places, whether or not the banks are unstable due to human activities, people try to keep a river in a single place.

River bank failure - Wikipedia

Description. A river bank can be divided into three zones: Toe zone, bank zone, and overbank area. The toe zone is the area which is most susceptible to erosion. Because it is located in between the ordinary water level and the low water level, it is strongly affected by currents and erosional events. The bank zone is above the ordinary high water level, but can still be …
