The Holderness coatline is in the North East of England in East Yorkshire. It runs between the Humber estuary in the south and a headland at Flamborough head.
- North East England
The causes of cliff collapse in the area:
- Strong prevailing winds creating longshore drift that moves material south along the coastline.
- The cliffs are made of a soft boulder clay. It will therefore erode quickly, especially when saturated. When saturated it's prone to slumping.
- Hydraulic action and abrasion are powerful processes.
- Destructive power of waves may be increasing due to slow sea level rise.
- Exposed to strong waves (fetch)
- Further up the coast, groyned have been used to stop the movement of sand southwards by longshore drift, and so the natural protection of a beach isn't avaliable.
- Sea level rise
Why the area needs protection:
- The village of Mappleton has approximately 50 properties
- Destroying farms
- Destroying main roads
- People are losing their homes
- The average rate of erosion is around 2m per year. (Since Roman times 4km lost and 30 villages destroyed)
- Industry at Eastington is being threatened
- Farms alongside the sea are devaluing and losing profits year on year as the cliff falls into the sea
- Many of the settlements rely heavily on tourism and if they are undefended their trade could diminish as facilities close down
