HOLDERNESS COAST CASE STUDY CLIFF COLLAPSE

However, in most place this is covered by glacial till deposited over 18, years ago. They have been successful in restricting waves from attacking the base of the cliffs here. As time goes on, this could mean that the headlands towns become more and more exposed to the force of the waves, while the coast in between the headlands will erode more and more until a stable bay is formed. The weak clay, stormy nature of the North Sea, and rising sea levels of 4mm per year mean that the future is bleak for parts of this coastline. Drainage Basin Hydrological System.

The video below shows Mappleton in Holderness Coast is a good example of rapid coastal erosion for reasons like: Take a look at our new resources in the shop Dismiss. The video below shows Mappleton in It works by absorbing — not reflecting — wave energy using large air spaces between the boulders and a broad surface area. However, in most places, this is covered by glacial till deposited over 18, years ago. The chalk headland has stumps and blowholes.

Cliff stabilisation has had a positive impact in managing the threat of mass movement.

Vegetation was planted on the cliffs to further stabilise them from mass movement. The video below shows Mappleton in The processes of erosion and weathering occurring are numerous but include hydraulic action, freeze thaw, abrasion, solution and carbonation on the clay. In the map above you can see that much of the land at the back is comprised of Chalk and much of the front land area is made up of Boulder Clay.

It is an excellent example of a spit. This is known as cliff stabilisation.

The land use to the south of Mappleton is predominantly agricultural. The impacts of coastal erosion on socio-economic aspects are: The first is the resuly of the strong prevailing winds creating longshore drift that moves material south along the coastline.

Stuxy defences and erosion at Mappleton. This process is called terminal groyne syndrome and happens frequently when groynes are stopped.

This is evident in the image below. Hold the line, do nothing. It has the unenviable reputation as the number one place in Europe for coastal erosion, and in a stormy year waves from the North sea can remove between 7 and 10m of coastline.

The area contains ‘text book’ examples of coastal erosion and deposition. The rock armour revetment has been very effective in protecting the cliff to the southern end of the settlement. During the winter they have only a thin layer of sand covering the underlying clay, and in high summer cast beaches build up enough for recreational purposes. Revetments are very expensive but long-lasting.

It was decided t6hat the cost of coastal defence for a foast of only people was less than the cost of building a new road. As time goes on, this could mean that the headlands towns become more and more exposed to the force of the waves, while the coast in between the headlands will erode more and more until a stable bay is formed. To counter this, local and regional authorities are nowadays trying set stuy integrated coastal zone management programmes for the whole coastline.

Holderness Coast – United Kingdom

The Holderness Coast is one of Europe’s fastest eroding coastlines. Mappleton is located on the Holderness Coast of East Yorkshire. By continuing to browse the site, you are agreeing to our use of cookies. In addition to the clay being vulnerable to erosion, it is also prone to slumping. The Holderness coast mainly consists of soft glacial drift cliffs, which have been cut back up to m over the last century.

This is around 2 million tonnes of material every year. Click on the image for a clearer picture. What is the rate of erosion at Barmston?

clllapse The exposed chalk of Flamborough provides examples of studh, features such as caves, arches and stacks.

Holderness Coast – Study Page. The effectiveness of the measures taken on the Holderness coast are variable, but in general hard measures are successful in stopping or at least slowing down the erosion locally. Indeed, today, farmland, tourist sites such as caravan parks and villages remain under threat. Soft Engineering Find out about soft engineering along the coast. Typhoon Haiyan Case Study.
