Seaford

• Rock arm at Newhaven

  Stopped longshore drift
• Sea wall at Seaford

  Was failing
• Management strategies used

  1. Terminal groyne at the east of the beach - stops longshore drift

  2. Rock armour - absorbs the waves energy

  3. Beach replenishment - Build up a shingle beach to absorb the waves energy

  4. Beach management - each year beach material is moved from the east to the west to counteract longshore drift
• Reasons for the schemes

  • Seaford had no beach material
  • Sea wall at Seaford was failing
• Terminal groyne at the east of the beach

  Stops longshore drift
• Rock armour

  Absorbs the waves energy
• Beach replenishment


  Builds up a shingle beach to absorb the waves energy
• Beach management


  Each year beach material is moved from the east to the west to counteract longshore drift
• The new beach attracts tourists
• The defences have protected Seaford during several stormy winters - reduced flood risk
• Increased tourism caused congestions and litter
• The groyne stops longshore drift leaving cliffs with no natural protection - more erosion
• To get the shingle for the beach it was dredged from the sea
