The Coastal System


  • Marine: waves, tides
  • People: human activities, economics, recreation/tourism, sea defences
  • Atmospheric: weather/climate, climate change, colar energy
  • Land: rock type/structure, tectonics


  • Erosion: hydraulic action, abrasion/corrasion, solution
  • Transportation: sediment cells, longshore drift
  • Deposition
  • Weathering/mass movement: freeze thaw, salt weathering, carbonation


  • Erosional landforms: cliffs, stacks, wave cut platforms, headlands
  • Depositional landforms: beaches, spits, salt marshes, sand dunes

Coastal sediment cells (aka littoral cells) are lengths of coastline that are pretty much entirely self contained for the movement of sediment. Each one is a costal system, so processes going on in one sediment cell don't affect the movement of sediment in another cell.


  • Backshore: starts at the cliff and ends at the foreshore
  • Foreshore: from the backshore to the nearshore
  • Nearshore: from the foreshore to the offshore
  • Offshore: from nearshore onwards
  • Berms: ridges of pebbles about 1-2m high. They're formed vy waves throwing these materials up onto the beach (often associated with contrstuctive waves)
  • Storm beaches: formed by storm waves. they're higher up the beach than the maximum high tide
