1

Rate of erosion (Holderness coast)

- Coastline is 61m long
- Erosion causes cliffs to collapse
- 1.8m of land is lost each year

2

Main reasons for erosion (Holderness coast)

- Easily eroded rock type -> Cliffs are made of boulder clay, likely to slump when it is wet (cc)
- Naturally narrow beaches ->Beaches slow waves down -> reducing erosive power -> less protection
- People worsening it -> Groynes built at Mappleton -> Stop material being moved further down -> beaches are narrower etc.
- Powerful waves -> Faces the PWD, brings waves from the NE -> Waves increase in power -> Coast is battered by highly erosive waves

Impacts on peoples lives (Holderness coast)

- Homes are at risk of collapsing into the sea
- Property prices have fallen
- Accessibility -> Roads near the top are at risk of collapsing into the sea
- Business -> Risk of losing jobs (Seaside caravan park in Ulrome is losing 10 pitches a year)
- Gas terminal -> 25m from cliff edge (supplies 25% of Britain's gas supply)
- 80,000 m2 of farmland is lost each year (farmers livelihoods)

Environmental impacts (Holderness coast)

- Some SSSI's are threatened (Lagoons near Easington are separated by a narrow strip -> Erosion will connect the lagoons to the sea and will be destroyed
