The coastline consists of low glacial till boulder clay. 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. The Holderness Coast is the most rapidly eroding coastline in Europe. 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 to a point where it is no longer a threat to the settlement. 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.

Hurricane Katrina Case Study. 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. 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 to a point where it is no longer a threat to the settlement. Flamborough Head is made of which rock type? Mappleton is located on the Holderness Coast of East Yorkshire.

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.

Revetments are very expensive but long-lasting. View the coasts menu. 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.

Although the coastal holdernwss 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.

Coastal defences and erosion at Mappleton. Holderness Coast is a good example of rapid coastal erosion for reasons like: There is a debate about whether or not human beings should attempt to defend coastlines. Mappleton is an s case study of an attempt at coastal management which has a negative impact further along the coast.

This is because water enters cracks and pore spaces in the rock, adding weight and making it slump. This is known as cliff stabilisation.

Spurn Point provides evidence of longshore drift on the Holderness Coast. There are two main reasons why this area of coast is eroding so rapidly. Pin Geogtaphy on Pinterest. 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.

The Holderness Coast

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. 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.

The second is that the cliffs caee made of soft boulder clay which erodes rapidly when saturated. The video below shows Mappleton in The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them.

This is around 2 million tonnes of material every year.

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. Tidal range at the Holderness coast is very high and can reach up to 7 m. Cliff holdernesz has had a positive impact in managing the threat of mass movement. 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 to a point where it is no longer a threat to the settlement.
