Coastal Management - HC

• What Coastal Management plan is Bridlington?

  Hold the Line
• Bridlington

  • operational fishing community
  • nationally important for sea birds
  • protected by Flamborough Head to the north and a Smithic sandbank (which lies offshore - 10km long and at spring low water rises 1.7m from the sea)
  • protected against north-easterly waves by the 4.7km long promenade
• What coastal management is Skipsea?

  Do nothing
• Skipsea

  • coastal management is limited to a small concrete revetment, protecting a residential area
• What coastal management is Hornsea?

  Hold the Line
• Hornsea

  • defences from 1900s - concrete sea walls, timber groynes, double sea wall, with promenade
  • ongoing refurbishment programme to ensure this has continued
  • problems with occasional sea water inundation due to breaching of existing flood defences have arisen.
• What coastal management plan is Mappleton?

  Hold the Line
• Mappleton

  • In 1991, almost £2m was spent on 2 rock groynes and a rock revetment to protect Mappleton and the B1242 coastal road
  • Blocks of granite were imported from Norway for the defences
  • Substantial beach has accumulated between the groynes halting erosion. The beach to the north is now significantly thicker and higher than to the south.
  • Erosion has sped up further south due to the sediment being trapped between the groynes.
• What coastal management plan is Withernsea?

  Hold the Line
• Withernsea

  • In 1875, the "Withernsea Improvement Company" built a concrete sea wall (£5000), which has recently been rebuilt.
  • Majority of Withernsea frontage has provided coastal protection in the form of the concrete sea walls and 2 rock revetments.
  • Storms during 1992 removed 4m of sand exposing the sea walls and houses to waves large enough to be on earthquake scale.
  • Emergency repairs were undertaken and rocks similar to Mappleton defences strengthened the defence.
  • Rock armour was placed in the South.
  • Main erosion still occurs down drift.
• What coastal management plan happens at Easington?

  Hold the Line
• Easington

  • 20% of Britain's gas comes onshore at the Easington Gas Terminal from the undersea gas pipeline stretching from Norway.
  • Sea wall built to protect the gas station cost £4.5m.
• What coastal management plan is Kilnsea?

  Do nothing
• Kilnsea

  • Uses soft engineering
  • has an earth embankment from the 15th century
  • a 2nd embankment has been built to trap sediment during high tide, building it up due to the land behind the first embankment being below sea level (2 metres below sea level).
  • the site was breached on 7th September 2003.
  • Half a million people live on the land.
