The average annual rate of erosion is around 2 metres per year. Beaches along the coast comprise mainly of shingle and sand eroded from the clay till. Vegetation was planted on the cliffs to further stabilise them from mass movement. However, in most place this is covered by glacial till deposited over 18, years ago. Indeed, today, farmland, tourist sites such as caravan parks and villages remain under threat. The processes of erosion and weathering occurring are numerous but include hydraulic action, freeze thaw, abrasion, solution and carbonation on the clay This has left a bay where the clay is and a headland jutting out to sea at Flamborough head.
Coastal defences and erosion at Mappleton. They have been successful in restricting waves from attacking the base of the cliffs here. The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them. The coastline consists of low glacial till boulder clay. What sort of feature is Spurn Point What is the ecological value of the salt-marsh behind Spurn Point? The site is self-funded and your support is really appreciated.
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. Erosion at Skipsea illustrates the human impact of erosion in areas where coastlines are not being defended.
Rates of erosion to the south of the defences at Mappleton have increased significantly since the construction of defences at Mappleton.

Coastal fieldwork Find out about coastal fieldwork techniques. Notice the impact of erosion to the south of the coastal defences.
Holderneess Engineering Find out about soft engineering along the coast. For a named coast either hard or soft rockdescribe its main features.
However, in most places, this is covered by glacial till deposited over 18, years ago. As the result holdernesw the coastal scheme at Mappleton no properties have been lost to the sea and the B remains safe from the risk of erosion.
The boulders are placed like a wall in a holdderness line of defence along the shoreline. Coastal management at Hornsea and Withernsea are examples of hard engineering solutions to coastal erosion. 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. Drainage Basin Lecel System. What is the rate of erosion at Barmston? The exposed chalk of Flamborough provides examples of erosion, features such as caves, arches and stacks.
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.
Waves during normally occurring storm events can reach up to 4 m. It extends 61km from Flamborough in the north to Spurn Point in the south. Hurricane Katrina Case Study. The Holderness Coast is one of Europe’s fastest eroding coastlines. Sea level rise associated with climate change and the prevailing north-easterly wind conspire to make this coast susceptible to rapid rates of coastal erosion.
Following the construction of defences, they increased to 3. What is plan to defend the terminal against the etudy 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 is because water enters cracks and pore spaces in the rock, adding weight and making it slump. The Holderness Coast holserness the most rapidly eroding coastline in Europe. As the result of this the beaches to the south have very little sediment and during low tide expose a combination of sand and clay boulders that have been eroded from the cliffs. Coastal defences and erosion at Mappleton. What is coastal erosion? Longshore drift no longer transports materials along this section of the coast.
What was the original life expectancy of the Easington terminal? The seabed consists of the glacial mud, sands and boulders, as do the cliffs. Geology The geology runs in bands, with a chalk layer at Flamborough in the Levdl, Boulder clay or till laid down in the last ice age south of that and finally river deposits in the Humber Estuary.
