  • FORMATION OF MEANDER
    • The formation of meanders is due to both deposition and erosion and meanders gradually migrate downstream.
    • 1
      • The force of the water erodes and undercuts the river bank on the outsideof the bend where water flow has most energy due to decreased friction.
        • 2
          • On the inside of the bend, where the river flow is slower, material is deposited, as there is more friction.

              • Over time the horseshoe become tighter, until the ends become very close together. As the river breaks through, the ends join, the loop is cut-off from the main channel. The cut-off loop is called an oxbow lake.
