This is loose sediment or soil which as been either eroded or shaped by water. The chalk headland has stumps and blowholes. Coastal defences and erosion at Mappleton. However some defences have been attempted. British Geological Survey – Holderness Coast.
The Holderness Coast is one of Europe’s fastest eroding coastlines. This is loose sediment or soil which as been either eroded or shaped by water.

In order to protect the cliffs along the front of Mappleton from undercutting, their gradient was also reduced artificially. 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.
A number of farmers have lost a significant amount of land to increased rates of erosion.

An annotated photograph to show the coastal management techniques used the protect Mappleton and their impact click to enlarge. Revetments are very expensive but long-lasting.
Beaches along the coast comprise mainly of shingle and sand eroded from geogrsphy clay till.
In addition to this the Holderness Coast is a popular destination for holidaymakers and during the summer months, the road is used heavily by tourists. Longshore drift no longer transports materials along this section of the coast. View the coasts menu. Open this Word document and complete all of the tasks using the Google map below ; Find out more about coastal erosion at this excellent website.
The coastline consists of low glacial till boulder clay. The second is that the cliffs are made of soft boulder holedrness which erodes rapidly when saturated. Please Support Internet Geography 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. The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them. What is boulder clay and how is it formed?
Why have groynes been built at Mappleton? The Holderness Coast is the most rapidly eroding coastline in Europe.
The Holderness Coast
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. The boulders are placed like a wall in a m line of defence along the shoreline. The construction of the stuvy groynes has created a larger, higher sandy beach for Mappleton. This is because water enters cracks and pore spaces in the rock, adding weight and making it slump.
Levwl video below shows Mappleton in 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.

Holderness Case Study Page
Generally, the natural beaches of Holderness are almost always narrow and unable to stop wave erosion. The site is self-funded and your support is really appreciated. Describe the texture of boulder clay What happens to sand and stones once they are eroded? Take a look at our new resources in the shop Dismiss. They are narrow as the result of the lack of major rivers bringing new sediment into the coastal budget.
As the result of the coastal scheme at Mappleton no properties have been lost to the sea and the B remains z from the risk of erosion. Soft Engineering Find out about soft engineering along the coast. Spurn Point provides evidence of longshore drift on the Holderness Coast. It provides access from smaller villages such as Mappleton and Aldbrough to larger settlements with a wider range of services such as Hornsea and Withernsea. What was the original life expectancy of the Easington terminal?
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.
