Case study (Coa)

• Holderness;

  • East of England
  • Landforms of erosion; wave cut platform and flamborough head (made of chalk)
  • Landforms of deposition; spurn head
• Reasons for management;

  • Housing - home to over 50,000 people.
  • Tourism - millions of tourists which bring money to local economy, road B1242 connects to town.
  • Industrial activity - land used for farming, Easton gas terminal which supplies gas across UK.
• Ways of management;

  • Groynes
  • Rock armour
  • At Hornsea, Mappleton and Easington
• Groynes at Hornsea;

  Positives;

  • Traps sediment from longshore drift, so beach widens.
  • Reduces energy in waves.
  • Reduces erosion.
  • Protects houses and businesses.

  Negatives;

  • Unnatural.
  • Visual pollution.
  • Prevents sediment from travelling further south, so smaller beaches.
• Rock Armour and Groynes at Mappleton;

  Positives;

  • Trap sediment from longshore drift, so beaches increased.
  • Prevents cliff erosion, which saved road B1242.

  Negitives;

  • Costs £2 million.
  • Increased erosion further south.
• Rock armour at Easington;

  • Absorbs wave energy.
  • Gas terminal is protected.

  Negatives;

  • Costs £6.8 million.
• Conflict with Groynes at Hornsea;

  + Business owners

  -Other towns don't get protected
• Conflict of Rock armour and groynes at Mappleton;

  + Roads are protected

  -Houses south are at risk
• Conflict of rock amrour at Easington;

  + Gas supply for UK

  - Other towns aren't protected
