What is the knock-on effect of this? It will therefore erode quickly, especially when saturated. On the other hand taking material from the seabed can kill habitats and is very expensive and has to be managed frequently. Accessibily to settlements have been affected along the coast as roads have collapsed into the sea, Impacts on environment: In addition, you have the added factor explain briefly sea level rise and land sinking Sorry to bring the bad news! Under lying the Holderness Coast is bedrock made up of Cretaceous Chalk. A virtual case study -.
This is one of the most vulnerable coastlines in the world and it retreats at a rate of one to two metres every year.

Groynes are wooden or stone fences that are built at right angles to the coast. The Holderness Coast is one of Europe’s fastest eroding coastlines. Spurn head is at risk of being eroded away because less material is being added.
The average annual rate of erosion is around 2 metres per year. East of London in the county of Kent.
Case study: coastal management in Holderness
Holderness Coast – Study Page. Soft engineering strategies are schemes to reduce the effects of erosion. Also stabalisation is cheap.
Beaches slow down waves, reducing their erosive power and acting as a barrier. However, this has increased erosion south of Mappleton. Coastal Management- strategies along a stretch of coastline. The Factors Affecting Erosion 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.

They create wider beaches which slow the waves down and give bigger protection along the coast. Why have groynes been built at Holerness Describe the texture of boulder clay What happens to sand and stones once they are eroded? Firefly needs a modern browser, so you may notice things look broken right now. A wall made out of hard material that reflects waves back out to sea.
Auth with social network: What is boulder clay and how is it formed? British Geological Survey – Holderness Coast.
Therefore, there are often powerful destructive waves along this coastline. Spurn head is at risk of being eroded away because less material is being added. Over time the land will become marshland and new habitats will occur.
Spurn Point provides evidence of longshore drift on the Holderness Coast. On average, over 2 metres of coastline is lost every year and powetpoint roman times it has lost 4km of land, and 29 villages, with this number rising even now. 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.
Longshore drift and beach material. Cowden Farm is now at risk of falling into the sea. Bays are forming between the protected areas and the protected cxse and becoming headlands which are being eroded more heavily, which means maintaining the defences in the protected areas is becoming more expensive.
