Auth with social network: Much of the land around Hull is made of Alluvium.

It is an excellent example of a spit. On average, over 2 metres of coastline is lost every year and since roman times it has lost 4km of land, and 29 villages, with this number rising even now.

Leave room on your sketch map for more detail to be added later An Overview of the Coastline This area of coastline is found between Flamborough head and Bridlington on the Yorkshire Coast.

The problem is caused by 4 main reasons: Published by Desmond Willets Modified over 4 years ago. Mappleton is an excellent case study of an attempt at coastal management. How far is the sea from the terminal now?

East of London in the county of Kent. Therefore, there are often powerful destructive waves along this coastline.

What is boulder clay and how is it formed? Presentation Transcript The Holderness Coastline case study We use this stretch of coastline to cover two case studies in one.

The area contains ‘text book’ examples of coastal erosion and deposition. A wall made out of hard material that reflects waves back out to sea. First look the location…. Beach nourishment is sand and shingles that are added to the beach from out to sea.
