  • Coastal Erosion- Holderness
    • Social Impacts
      • Property prices along the coastline have fallen especially for those at risk.
      • Around 30 villages lost since Roman times.
    • Economic Impacts
      • Visitor numbers in bridlington dropped by 30% from 1998-2006(may be due to other reasons aswell)
      • Caravan parks at risk from erosion e.g seaside caravan park, Ulrome- losing average 10 pitches a year.
      • £2 million spent at mappleton to protect the coast.
      • Gas terminal at Easington is at risk (25m from the cliff edge).
        • this terminal accounts for 25% british gas supply.
      • 80,000 m2 good quality farmland lost each year.
        • Huge effect on farmers livelihoods'.
    • Environmental Impacts
      • Some SSIs (sites of specific scientific interest) are threatened.
        • The Lagoons near Easington- part of an SSI. colony of over 1% of british breeding population of little terns. lagoons seperated from the sea by a ***** of sand and shingle- any erosion would connect lakes and sea= lagoons destroyed
    • Main Reasons for rapid Erosion
      • Powerful waves - theyre powerful because of:
        • Long fetch (from arctic ocean)
        • Coast faces Dominant wind and wave direction (north-east)
      • Narrow Beaches- beaches slow waves reducing erosive power but narrow beaches protect the cliff less.
        • Flamborough Head stops Sediment- replenishing beaches along holderness. Also made of chalk, which dissolves when eroded- rather than aking sand for the beaches.
      • Easily Eroded rock type
        • cliffs are mostly made of boulder clay(till). its easily eroded through corrasion and prone to slumping when wet.
