The types of River Erosion

There are 4 Types of River Erosion which are Hydraulic Action, Attrition, Abrasion and Solution.

Abrasion: Rocks carried by the river smash into the bank and the bed.


Attrition: Rocks being carried by the river smash together and break into smaller, smoother and rounder particles.


Hydraulic Action: The force of the river against the banks can cause air to be trapped in cracks and crevices. The pressure weakens the banks and gradually wears it away.

Solution: Soluble particles are dissolved into the river.
