Holderness coast, cliff collapse and coastal management

Holderness coast, cliff collapse and coastal management

1. the coastline is 61km long

2. 1.8 m of land is lost every year

3. reasons for rapid erosion

   • the rock type is easily eroded as it is boulder clay
   • naturally narrow beaches- the narrower the beach the more power a wave has
   • groynes have been built further up in Mappleton
     • meaning that sediment isn't washed further down so the coast eroded's more easily
   • they face the prevailing wind which means the waves are more powerful

4. impact on peoples lives

   • homes near the cliffs are at risk
   • property prices have fallen
   • roads have fallen off the cliff so access has become difficult
   • businesses are at risk from erosion
     • so people lose their jobs

5. environmental impact

   • SSSI's are threatened
     • lagoons destroyed by salt water
