sediment cells - Coggle Diagram

- - - - people trampling on the sand dunes causing erosion
        
        damages vegetation nd causes sand to become loose winter storms causes further erosion and removal of sand
      - these following steps are the knock on effects from positive feedback
  - - - sand dunes are restored from the sand blowing back in
      - these two types of feedback create dynamic equilibrium within a sediment cell
- - - - Akosombo
      - creates 3,000 jobs for locals
    - - sediment builds up behind the dam
      - disrupts the dynamic equilibrium and stops positive feedback/ input
        
        results in beaches such as meta being starved from sediment
        
        this results in erosion through no beaches protecting it
      - breakwater built further east down the coast to protect new port
        
        new port bring in income for Africa to allow the exchange of goods
        
        destruction of this effects economy of northern africa
        
        this breakwater stops sediment flow and deposits on west coast
