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. Notice the impact of erosion to the south of the coastal defences. However some defences have been attempted. Cliff stabilisation has had a positive impact in managing the threat of mass movement. 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.
The video below shows Mappleton in The rock armour revetment has been very effective in protecting the cliff to the southern end of the settlement. Hurricane Katrina Case Study. 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. Revetments are very expensive but long-lasting.

It works by absorbing — not reflecting — wave energy using large air spaces between the boulders and a broad surface area. Mappleton is an excellent case study of an attempt at coastal management.
Typhoon Haiyan Case Study. The second is that the cliffs are made of soft boulder clay which erodes casd when saturated. This is known as cliff stabilisation.
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 Coast is a great case study to casd when examining coastal processes and the features associated with them. 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.

The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them. Tidal range at the Holderness coast is very high and can reach up to 7 m.
Online Activities [Online activities]: Drainage Basin Hydrological System. The Holderness Coast is one of Europe’s fastest eroding coastlines. 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 around 2 million tonnes of material every year.
You can clearly see the area to the south has very gently sloping beaches and high levels of erosion where the coastal defences stop.
There are two main reasons why this area of coast is eroding so rapidly. The coastline consists of low glacial till boulder clay. Kerala flood case study.
Spurn Point provides evidence of longshore drift on the Holderness Coast. Pin It on Pinterest. The chalk headland has stumps and blowholes.
The boulders are placed like a wall in studh m line of defence along the shoreline. They have been successful in restricting waves from attacking the base of the cliffs here. It extends 61km from Flamborough in the north to Spurn Point in the south.

In addition to the lqndforms being vulnerable to erosion, it is also prone to slumping.
It extends 61km from Flamborough in the north to Spurn Point in the south. Following the construction of defences, they increased to 3.
