River Processes

• Hydraulic action


  where the sheer force of the water erodes the stones, bed and banks of the river
• Abrasion


  where stones in transport are thrown into the bed and the banks eroding them
• Corrosion


  where weak acids within the water react with the rocks and bed and bank of the river
• Attrition


  where stones in transport are thrown into one another
• Solution


  where material is dissolved within the water
• Suspension


  where small particles are held up or suspended in the water
• Saltation


  Saltation
• Traction


  Traction the rolling motion of sediment along the bed - normally much larger sediment.
• Deposition


  this is the laying down of sediment in the river channel or on floodplains
