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. Soft Engineering Find out about soft engineering along the coast. Indeed, today, farmland, tourist sites such as caravan parks and villages remain under threat. Related Topics Use the images below to explore locations along the Holderness Coast. Because the clay is an unconsolidated WEAK mass of clay particles and boulders it erodes more rapidly than the more resistant rock of chalk in the north. However some defences have been attempted. This is around 2 million tonnes of material every year.
This is known as cliff stabilisation. Longshore drift no longer transports materials along this section of the coast. This has left a bay where the clay is and a headland jutting out to sea at Flamborough head. View The Holderness coastline in a larger map. This process is called terminal groyne syndrome and happens frequently when groynes are stopped.

The Holderness Coastline is in the North of England and runs between the Humber Estuary in the south and a headland at Flamborough head.

It also widely used by local farmers for access to the rich agricultural land in the area. A number of farmers have lost a significant amount of land to increased rates of erosion. The construction holxerness the rock groynes has created a larger, higher sandy beach for Mappleton.

Erosion at Skipsea illustrates the human impact of holdegness in areas where coastlines are not being defended. 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. Although wave refraction focuses the waves energy on the layered and faulted rocks of Flamborough head, eroding the calk, the incredibly weak nature of the clay still means that it erodes faster than the chalk.
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 coasg river deposits in the Humber Estuary.

Waves during normally occurring storm events can reach up to 4 m. The Holderness Coastline is in the North of England and runs between the Humber Estuary in lajdforms south and a headland at Flamborough head.
It works by absorbing — not reflecting — wave energy using large air spaces between the boulders and a broad surface area. Revetments are very expensive but long-lasting. Pin It on Pinterest.

The first is the resuly of the strong prevailing winds creating longshore drift that moves material south along the coastline. Spurn Point hlderness evidence of longshore drift on the Holderness Coast. Spurn Point provides evidence of longshore drift on the Holderness Coast.

Defending the Holderness Coastline There is a debate about whether or not human beings should attempt to defend coastlines. Coastal fieldwork Find out about coastal fieldwork techniques. The seabed consists of the glacial mud, sands and boulders, as do the cliffs.

Vegetation was planted on the cliffs to further stabilise them from mass movement. Because the clay is an unconsolidated WEAK mass of clay particles and boulders it erodes more rapidly than the more resistant rock of chalk in the north.
The second is that the cliffs are made of soft boulder clay which erodes rapidly when saturated. As the movement of sediment has been disrupted due to the construction of the stone groynes material previously feeding the beaches to the south of the Mappleton is restricted. View the coasts menu.
The Holderness Coast
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.
What is coastal deposition? 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. Mappleton is an excellent case study of an attempt at coastal management which has a negative impact further along the coast.
The area contains ‘text book’ examples of coastal erosion and deposition. The exposed chalk of Flamborough provides examples of erosion, features such as caves, arches and stacks.
