CS - Holderness Coast Flashcards
Where is the Holderness Coast?
The Holderness Coast is located on the North-East coast of England; it is one of the fastest eroding coastlines in Europe due to its soft geology
Describe the Holderness Coast’s geology…
The soft boulder clay that makes up most of the area is easily eroded and then the material is transported southwards due to long shore drift - this has led to the formation of Spurn Head at the mouth of Humber
Towards the north of the coastline Flamborough head is made up of harder chalk and many attractive land forms of erosion are found here
What is Spurn Head?
Spurn Head is a spit created by deposition. Behind this spit is a large salt marsh which contains many race species
As the management methods up the coast have been put in place less sediment is getting down to replace the sand on the spit - groynes have been put in place to ensure the spit is safe and the marsh behind remains
What has been done to try and manage Long-Shore-Drift on the coastline near Mappleton?
Two rock groynes have been built to encourage the build up of beach in front of Mappleton by trapping material. This mean’t that the waves would break on the beach rather than the cliffs, thus, providing a large barrier for protection
What has been done to try and manage Long-Shore-Drift on the coastline near Withernsea?
Large rock revetments shipped from Norway have been placed to take the force of the waves which protects the land behind as a result
A large sea wall has also been constructed to protect the cliffs from weathering and erosion from the sea
Why is the town of Withernsea protected by coastal management?
Because it is a major tourist attraction
How is the gas plant in Easington being protected?
It is protected by revetments that take most of the force from the powerful waves
