HOLDERNESS COAST CASE STUDY CLIFF COLLAPSE

These large granite boulders were imported from Scandinavia and deposited by barge along the coast. This means that even at high tide waves do not reach the base of the cliffs along the seafront at Mappleton and the erosion has slowed to a point where it is no longer a threat to the settlement. The Holderness Coast is located on the east coast of England. There are two main reasons why this area of coast is eroding so rapidly. Erosion at Skipsea illustrates the human impact of erosion in areas where coastlines are not being defended. The processes of erosion and weathering occurring are numerous but include hydraulic action, freeze thaw, abrasion, solution and carbonation on the clay. Online Activities [Online activities]:

Pin It on Pinterest. This inevitably means that some of the Holderness coast will be eroded in order to achieve a more efficient coastal shape. This has left a bay where the clay is and a headland jutting out to sea at Flamborough head. Erosion at Skipsea illustrates the human impact of erosion in areas where coastlines are not being defended. Generally, the natural beaches of Holderness are almost always narrow and unable to stop wave erosion. Longshore drift no longer transports materials along this section of the coast.

However some defences have been attempted.

The Holderness Coast is located on the east coast of England. InMappleton was under threat from losing 30 houses and its main road. Rates of erosion to the south of the defences at Mappleton have increased significantly since the construction of defences at Mappleton.

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. This means that even at high tide waves do not reach the base of the cliffs along the seafront at Mappleton and the erosion has slowed to a point where it is no longer a threat to the settlement.

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. Revetments are studdy expensive but long-lasting.

The site is self-funded and your support is really appreciated. The second is that the cliffs are made of soft boulder clay which erodes rapidly when saturated.

Cliff stabilisation has had a positive impact in managing the threat of mass movement. The second is that the cliffs are made of soft boulder clay which erodes rapidly when saturated. Complete description of case study. The Holderness Coast is one of Europe’s fastest eroding coastlines. The effectiveness of the measures taken on the Holderness coast are variable, but in general hard measures are successful in stopping stuyd at least slowing down the erosion locally.

Holderness – A case study of cause, effect and response

Human interference, such as sea defences, causes rapid erosion of the unprotected beaches and cliffs. The average annual rate of erosion is around 2 metres per year.

Mappleton is located on the Holderness Coast of East Yorkshire. Spurn Point provides evidence of longshore drift on the Holderness Coast.

The Holderness Coast

Hurricane Katrina Case Study. The sea defences seem to be creating artificial headlands holdernezs erosion continues on both sides. The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them.

Complete description of case study. Coastal defences and erosion at Mappleton. This is known as cliff stabilisation. It is this soft boulder clay that is being rapidly eroded. To counter holdeerness, local and regional authorities are nowadays trying set up integrated coastal zone management programmes for the whole coastline.

These large granite boulders were imported from Scandinavia and deposited by barge along the coast. The second is that the cliffs are made of soft boulder clay which erodes rapidly when saturated. Vegetation was planted on the cliffs to further stabilise them from mass movement. It works by absorbing — not reflecting — wave energy using large air spaces between the boulders and a broad surface area.

As the result of the coastal scheme at Mappleton no properties have been lost to the sea and the B remains safe from the risk of erosion.

The coast is subject to the full force of the waves from the North Sea, with little attenuation before they reach the cliff line. Hold the line, do nothing. Coastal fieldwork Find out about coastal studh techniques.
