- 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
- Some SSIs (sites of specific scientific interest) are threatened.
- 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.
- Powerful waves - theyre powerful because of:
- Social Impacts
