Under lying the Holderness Coast is bedrock made up of Cretaceous Chalk. In order to protect the cliffs along the front of Mappleton from undercutting, their gradient was also reduced artificially. Typhoon Haiyan Case Study. If you’ve found the resources on this page useful please consider making a secure donation via PayPal to support the development of the site. 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. Mappleton is a small village that could become village number 30 lost to the sea. 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.
Holderness Coast – Study Page. It also widely used by local farmers for access to the rich agricultural land in the area. The road running through it, the B links towns along the coastline and would have been lost to coastal erosion if protection measures were not put into place. Soft Engineering Find out about soft engineering along the coast. 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.
There is a debate about whether or not human beings should attempt to defend coastlines. The Holderness Coast is the hollderness rapidly eroding coastline in Europe.
Cliff stabilisation has had a positive impact in managing the threat of mass movement. The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them.
It also widely used by local farmers for access to the rich agricultural land in the area. Mappleton is a small village that could become village number 30 lost to the sea.
The soft boulder clay underlying Hornsea provides clear evidence of the erosional power of the sea. What is being done at Withernsea to protect the town? British Geological Survey – Holderness Coast. These large granite boulders were imported from Scandinavia and deposited by barge along the coast. The first is the result of the strong prevailing winds creating longshore drift that moves material south along the coastline.
The census indicated that the parish of Mappleton had a population ofand increase from in Coastal fieldwork Find out about coastal fieldwork techniques.
Coastal management – Revision 3 – GCSE Geography – BBC Bitesize
This is around 2 million tonnes of material every year. This process is called terminal groyne syndrome and happens frequently when groynes are stopped. So, blocks of granite were brought in and placed along the cliff base and 2 rock sfudy were put into place to trap sediment moving because of longshore drift. How far is the sea from the terminal now?
It is an excellent example of a spit. Tidal range at the Holderness coast geogralhy very high and can reach up to 7 m. The boulders are placed like a wall in a m line of defence along the shoreline.
The Holderness Coast
Typhoon Haiyan Case Study. InMappleton was under threat from losing 30 houses and its main road.
Generally, the natural beaches of Holderness are almost always narrow and unable to stop wave erosion. Take a look at our new resources in the shop Dismiss.
Holderness Coast – Study Page. Indeed, today, farmland, tourist sites such as caravan parks and villages remain under threat. 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.
This has left a bay where the clay is and a headland jutting out to sea at Flamborough head. The construction of the rock groynes has created a larger, higher sandy beach for Mappleton.
Hurricane Katrina Case Study. The second is that the cliffs are made of soft boulder clay which erodes rapidly when saturated. It is this soft boulder clay that is being rapidly eroded.
