lower course landscapes

• | meanders

  • in the middle course, width, depth and velocity increases; river erodes sideways & forms large bends which get bigger & wider; forming a meander
  • outer bend, where there is faster current there’s greater erosion & creates a river cliff
  • inner bend = deposition
• | OXBOW LAKES!!

  1. narrow neck of meander is eroded
  2. water takes quickest route
  3. deposition takes place, sealing off meander
  4. meander neck has been completely cut through
  5. oxbow lake left behind when meander is completely cut off
