  • Erosion Processes
    • Hydraulic Actions
      • When the force of the river (only) removes particles from the river's banks and beds.
    • Solution
      • Is when acids in the river dissolve rocks, such as limestone, which form the banks and bed. This can occur at any point of the rivers course.
    • Abrasion
      • The river carries with it particles of sand and silt and moves pebbles and boulders at times of high flow. This material rubs against the bed and the banks of the river and wears them away.
    • Attrition
      • Is when boulders and other materials, which are being transported along the bed of the river, which collide and break up into smaller pieces. This is more likely to occur when rivers are still flowing in highland areas.
