However some defences have been attempted. 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. It also widely used by local farmers for access to the rich agricultural land in the area. The Holderness Coastline is in the North of England and runs between the Humber Estuary in the south and a headland at Flamborough head. The weak clay, stormy nature of the North Sea, and rising sea levels of 4mm per year mean that the future is bleak for parts of this coastline. This is known as cliff stabilisation.
Indeed, today, farmland, tourist sites such as caravan parks and villages remain under threat. In , Mappleton was under threat from losing 30 houses and its main road. The area contains ‘text book’ examples of coastal erosion and deposition. The soft boulder clay underlying Hornsea provides clear evidence of the erosional power of the sea. Erosion at Skipsea illustrates the human impact of erosion in areas where coastlines are not being defended. In the map above you can see that much of the land at the back is comprised of Chalk and much of the front land area is made up of Boulder Clay.
The Holderness Coast
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. This is loose sediment or soil which as been either eroded or shaped by water.
Coasts menu Where do you want to go now? Longshore drift no longer transports materials along this section of the coast. Rates of erosion to the south of the defences at Mappleton have increased significantly since the construction of defences at Mappleton. Holderness Coast Case Study.
The site is self-funded and your support is really appreciated. Much of the land around Hull is made of Alluvium. Why have groynes been built at Mappleton?
This process is called terminal groyne syndrome and happens frequently when groynes are stopped. You can clearly see the area to the south has very gently sloping beaches and high levels of erosion where holverness coastal defences stop. Geofile – Holderness Coastal Management.

BBC Bitsize footage – Holderness coast. The Holderness Coast is located on the east coast of England. To get a better experience, try one of the supported browsers listed here. Spurn Point provides evidence of longshore drift on the Holderness Coast.
Longshore drift tends to transport material south which has resulted in the formation of Spurn Point, a spit formed at the mouth holverness the Humber Estuary. Describe the texture of boulder clay What happens to sand and stones once they are eroded? The construction of the rock groynes has created a larger, higher sandy beach for Mappleton.
So, blocks of granite were brought in and placed along the cliff base and 2 rock groynes were put into place to trap sediment moving because of longshore drift.
Vegetation was planted czse the cliffs to further stabilise them from mass movement. Generally, the natural beaches of Holderness are almost always narrow and unable to stop wave erosion.
What was the original life expectancy of the Easington terminal? The Holderness Coastline is in the North of England and runs between the Humber Estuary in the south and a headland at Flamborough head. As the result of this the beaches to the south have very little sediment and during low tide gsography a combination of sand and clay boulders that have been eroded from the cliffs.

The land use to the south of Mappleton is predominantly agricultural.
holeerness It extends 61km from Flamborough in the north to Spurn Point in the south. Holderness Coast is a good example of rapid coastal erosion for reasons like: The boulders are placed like a wall in a m line of defence along the shoreline. It is this soft boulder clay that is being rapidly eroded. It works by absorbing — not reflecting — wave energy using large air spaces between the boulders and a broad surface area. Notice the impact of erosion to the south of the coastal defences.
