  head land and bay
• what is an depositional landform in swanage bay ?


  Sand dunes - the windy blows sand to shore and the narrow grass catches it creating sand dunes

  Lyme Regis
• what’s hard engineering 


  when structures are built to prevent erosion taking place
• what’s soft engineering ?

  when strategies are put in place to reduce erosion by working alongside natural processes
• what’s managed retreat 


  a sustainable strategy where land allowed to flood and human activity is moved from coastline.
• where is Lyme Regis ?


  Dorset
• what are the reasons for coastal management?


  much of the town is built on unstable cliffs / landslides and part of the town falls into the ocean

  Banbury
• why does Banbury have a flood management scheme ?


  it’s built in flood plains and previous damage from floods has cost £12.5 billion.
• what’s is the flood management scheme in Banbury ? 


  a flood storage reservoir upstream to store floodwater preventing water entering the town

• What’s hydraulic action ?


  Force of water pushing air and water into cracks in the rocks widening the rocks until it breaks away
• what is abrasion ?


  when pebbles grind along a rock platform , like sand paper
• what is corrosion ?


  Rocks or stones can be eroded as water gets into cracks and holes and dissolves the rock through chemical change
• what’s attrition ?


  when rocks that the sea or river is carrying knock against each other and become smaller and more rounded
• what’s solution ?


  when water dissolves certain types of rocks
• what’s Vertical erosion ?


  cowards erosion that makes the river bed deeper
• what’s lateral erosion ?


  sideways erosion wearing the river banks away to make the river much wider
• whats traction ?


  a method of transportation for large stones or boulders in a river
• what is saltation ?


  Saltation is the process of particles being transported by bouncing or hopping along the ground due to wind or water flow.
• What’s suspension ?


  lighter sediment is carried within the water

  vshaped valley, rapids and waterfalls
• what are the middle course river processes for the river tees ?


  Meanders and oxbow lakes
• what are the lower course river processes in the river tees ?


  Great lateral erosion creating floodplains
