River Processes

The four main forms of river erosion

  • 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.
  • Abrasion - rocks carried along by the river wear down the river bed and banks.
  • Attrition - rocks being carried by the river smash together and break into smaller, smoother and rounder particles.
  • Solution - soluble particles are dissolved into the river.
