HOLDERNESS COAST CASE STUDY CLIFF COLLAPSE

It is an excellent example of a spit. Rates of erosion to the south of the defences at Mappleton have increased significantly since the construction of defences at Mappleton. There are two main reasons why this area of coast is eroding so rapidly. An annotated photograph to show the coastal management techniques used the protect Mappleton and their impact click to enlarge. Hold the line, do nothing. This is evident in the image below.

On average, the coastline of Holderness erodes at about 2m per year, mainly during storms and tidal surges. In between the towns with a fixed coastline, bays seem to be developing due to this erosion. The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them.

Generally, the natural beaches of Holderness are almost always narrow and unable to stop wave erosion. Vegetation was planted on the cliffs to further stabilise them from mass movement. Indeed, today, farmland, tourist sites such as caravan parks and villages remain under threat.

What is being done at Withernsea to protect the town? The Holderness Coast is located on the east coast of England. During the winter they have only a thin layer of sand covering the underlying clay, and in high summer the beaches build up enough for recreational purposes.

The coastline starts with blowholes, stacks and stumps at Flamborough, and culminates with Spurn head, a very large spit that runs across part of Humber Estuary.

Coastal management – Revision 3 – GCSE Geography – BBC Bitesize

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. In order to protect the cliffs along the front of Mappleton from undercutting, their gradient was also reduced artificially. The exposed chalk of Flamborough provides examples of erosion, features such as caves, arches and stacks. The cloff armour revetment has been very effective in protecting the cliff to the southern end of the settlement.

Human interference, such as collspse defences, causes rapid erosion of the unprotected beaches and cliffs. Related Topics Use the images below to explore locations along the Holderness Coast.

Although wave refraction focuses the waves energy on the layered and faulted rocks of Flamborough head, eroding the calk, the incredibly weak nature of the clay still means that it erodes faster than the chalk. Mappleton is an excellent case study of an attempt at coastal management which has a negative impact further along the coast.

What is convectional rainfall? This is around 2 million tonnes of material every year. It is an excellent example of a spit. The sea attempts to build up an equilibrium gradient by eroding these soft cliffs behind the beach, to which the strong waves have easy access.

This has left a bay where the clay is and a headland jutting out to sea at Flamborough head. 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 collase village now suffers from an even greater rate of erosion.

What features of collapxe are visible at Flamborough Head? Online Activities [Online activities]: On average, the coastline of Holderness erodes at about 2m per year, mainly during storms and tidal surges.

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. The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them. Spurn Point provides evidence of longshore drift on the Holderness Coasr.

The sea defences seem to be creating artificial headlands because erosion continues on both sides. It works by absorbing — not reflecting — wave energy using large air spaces between the boulders and a broad surface area. A number of farmers have lost a significant amount of land to increased rates of erosion.
