The boulders absorb the wave energy they reduce the risk of erosion against the coast. Take a look at our new resources in the shop Dismiss. The problem is caused by 4 main reasons: At Holderness the environment is primarily one of fetch-limited wind wave development, the dominant wave direction is north-easterly, creating a north-south orientated net longshore current. The plan was to create an obstruction which would lead to the deposition of a beach – which would absorb the power of the waves and protect the cliff.
It is this soft boulder clay that is being rapidly eroded. This tourism is under threat, so the government has spent millions of pounds on sea defences. Cover the answers to the questions on each slide in your talk. Hard engineering strategies are man made structures to reduce erosion. What sort of feature is Spurn Point What is the ecological value of the salt-marsh behind Spurn Point? Auth with social network: The problem is caused by 4 main reasons:
To make this website work, we log user data and share it with processors. However, this has increased erosion south of Mappleton.
First look the location…. Spurn Point provides evidence of longshore drift on the Holderness Coast. If you wish to download it, please recommend it to your friends in any social system.
Published by Crystal Blake Modified over 3 years ago. Mappleton is an excellent case study of an attempt at coastal management which has a negative impact further along the coast. Rock armour are large boulders that are built up along the coast.
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. The average annual rate of erosion is around 2 metres per year. The exposed chalk of Flamborough provides examples of erosion, features such as caves, arches and stacks.

Typhoon Haiyan Case Study. The major part of the area we will study lies within the Reculver.
Holderness Case Study Page
The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them. Due to the erosion of the cliffs, the village is under threat. Vegetation was planted on the cliffs to further stabilise them from mass movement.

Case study: coastal management in Holderness
This icon indicates that. As the result of this the beaches to the south have very little sediment and during low tide expose a combination of sand and clay boulders that have been eroded from the cliffs.
Coasts Revision Booklet This belongs to: Mappleton and the cliffs are no longer at great risk from erosion. Under lying the Holderness Coast is bedrock made up of Cretaceous Chalk.
The coastline consists of low glacial till boulder clay. Although the coastal defences have had a positive impact in terms of reducing the rate of erosion and protecting the village and main road, the area directly south of the village now suffers from an even greater rate of erosion.
The land use to the south of Mappleton is predominantly agricultural.
Holderness – A case study of cause, effect and response
Longshore cilff no longer transports materials along this section of the coast. Pin It on Pinterest. It is an excellent example of a spit. What should happen to the Holderness coastline? It will therefore erode quickly, especially when saturated. The soft boulder clay underlying Hornsea provides clear evidence of the erosional power of the sea. What features of erosion are visible at Flamborough Head?
