HOLDERNESS COAST LANDFORMS CASE STUDY

Longshore drift tends to transport material south which has resulted in the formation of Spurn Point, a spit formed at the mouth of the Humber Estuary. The Holderness Coast is located on the east coast of England. In order to protect the cliffs along the front of Mappleton from undercutting, their gradient was also reduced artificially. 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. Take a look at our new resources in the shop Dismiss. The exposed chalk of Flamborough provides examples of erosion, features such as caves, arches and stacks. The geology runs in bands, with a chalk layer at Flamborough in the North, Boulder clay or till laid down in the last ice age south of that and finally river deposits in the Humber Estuary.

This is known as cliff stabilisation. 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. 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.

Geology The geology runs in bands, with a chalk layer at Flamborough in the North, Boulder clay or till laid down in the last ice age south of that and finally river deposits in the Humber Estuary. They are narrow as the result of the lack of major rivers bringing new sediment into the coastal budget.

The land use to the south of Mappleton is predominantly agricultural. 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 landdforms a point where it is no longer a threat to the settlement.

The construction of the rock groynes has created a larger, higher sandy beach for Mappleton. If you’ve found the resources on this site useful please consider making a secure donation via PayPal to support the development of the site.

However some defences have been attempted. It extends 61km from Flamborough in the north to Spurn Point in the south. The area contains ‘text book’ examples of coastal erosion and deposition.

Coastal fieldwork Find out about coastal fieldwork techniques. The exposed chalk of Flamborough provides examples of erosion, features such as caves, arches and stacks. However, in most places, this is covered by glacial till deposited over 18, years ago. Underlying the Holderness Coast is bedrock made up of Cretaceous Chalk.

Following the construction labdforms defences, they increased to 3. The Holderness Coast is the most rapidly eroding coastline in Europe. Longshore drift tends to holdenress material south which has resulted in the formation of Spurn Point, a spit formed at the mouth of the Humber Estuary.

The processes of erosion and weathering occurring are numerous but include hydraulic action, freeze thaw, abrasion, solution and carbonation on the clay. Beaches along the coast comprise mainly of shingle and sand eroded from the clay till. There are two main reasons why this area of coast is eroding so rapidly. 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.

Mappleton is located on the Holderness Coast of East Yorkshire.

This is because water enters cracks and pore spaces in the rock, adding weight and making it slump. A number of farmers have lost a significant amount of land to increased rates of erosion. It works by absorbing — not reflecting — wave energy using large air spaces between the boulders and a broad surface area. Click cxse the image for a clearer picture.

Erosion at Skipsea illustrates the human impact of erosion in areas where coastlines are not being defended. These large granite boulders were imported from Scandinavia and holdernss by barge along the coast. In order to protect the cliffs along the front of Mappleton from undercutting, their gradient was also reduced artificially.

The coastline today is around 4km inland from where it was in Roman times, and there are many LOST villages of the Holderness coastline that have long disappeared into the sea. Geology The geology runs in bands, with a chalk layer at Flamborough in the North, Boulder clay or till laid down in the last ice age lxndforms of that and finally river deposits in the Humber Estuary.

It is an excellent example of a spit. Drainage Basin Hydrological System. It extends lndforms from Flamborough in the north to Spurn Point in the south. The Holderness Coast is one of Europe’s fastest eroding coastlines.
