Geology The boulder clay has very little resistance to erosion, especially when wet, making it very susceptible to erosion The two main types of rock on the Holderness coast are Boulder clay and chalk. What sort of feature is Spurn Point What is the ecological value of the salt-marsh behind Spurn Point?
The Holderness Coastline case study We use this stretch of coastline to cover two case studies in one. The Holderness Coast is one of Europe’s fastest eroding coastlines. What was the original life expectancy of the Easington terminal? Rock armour are large boulders that are built up along the coast. There are three main reasons for this erosion:

Longshore drift and beach material Geology The boulder clay has very little resistance to erosion, especially when wet, making it very susceptible to erosion The two main types of rock on the Holderness coast are Boulder clay and chalk Fetch Holderness is exposed to winds and waves from the north-east, which have a small fetch of about km.
Spurn Point provides evidence of longshore drift on the Holderness Coast. My presentations Profile Feedback Log out. Geology The boulder clay has very little resistance to erosion, especially when wet, making it very susceptible to erosion The two main types of rock on the Holderness coast are Boulder clay and chalk.
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.

Holderness coast management strategy problems Groynes protect local area but cause narrow beaches to form further down the Holderness coast which increase erosion further down the coast e. This means that …. The material produced from the erosion of Holderness is normally transported south into the Humber estuary and down the Lincolnshire coast.
There are also some other factors that affect the fetch …… Also, people have recently made the clast worse by protecting the beach with groynes just north of your house. The Atlantic fetch is km or more, and its currents add energy to poerpoint in the North sea. It will therefore erode quickly, especially when saturated.
This means the beaches are narrower and more prone to erosion. The average annual rate of erosion is around 2 metres per year.
Cowden Farm is now at hllderness of falling into the sea. However, this has increased erosion south of Mappleton. The increased threat of sea level rise due to climate change, means that other places will need to consider the sustainability of coastal defence strategies for the future.
It prevents erosion holdernness the coast and acts like a barrier. Firefly needs a modern browser, so you may notice things look broken right now. It is this soft boulder clay that is being rapidly eroded. Hard engineering strategies are man made structures to reduce erosion. What should happen to the Holderness coastline?
