Types of Erosion


There are four main forms of river erosion:

  • Hydraulic action - the force of the water wears away the river bank from underneath

Bank erosion

  • Attrition - rocks being carried by the river smash together and break into smaller particles. Over time, they become smaller and eventually reduced to fine particles called silt

  • Abrasion - stones that the river is carrying bump into the banks and wear them away

  • Solution - acids in the water slowly dissolve the river banks and the stones that the river is carrying (especially limestone)
