HOLDERNESS CASE STUDY A LEVEL GEOGRAPHY

Rates of erosion to the south of the defences at Mappleton have increased significantly since the construction of defences at Mappleton. What is plan to defend the terminal against the sea? The coastline today is around 4km inland from where it was in Roman times, and there are many LOST villages of the Holderness coastline that have long disappeared into the sea. Following the construction of defences, they increased to 3. It is this soft boulder clay that is being rapidly eroded. You can clearly see the area to the south has very gently sloping beaches and high levels of erosion where the coastal defences stop.

The coastline starts with blowholes, stacks and stumps at Flamborough, and culminates with Spurn head, a very large spit that runs across part of Humber Estuary. It also widely used by local farmers for access to the rich agricultural land in the area. The Holderness Coast is the most rapidly eroding coastline in Europe. British Geological Survey – 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.

Mappleton – A Level Geography

It extends 61km from Flamborough in the north to Spurn Point in the south. It works by absorbing — not reflecting — wave energy using large air spaces between the boulders and a holxerness surface area.

Much of the land around Hull is made of Alluvium.

Beaches along the coast comprise mainly of shingle and sand eroded from the clay till. Although the coastal defences have z a positive impact in terms of reducing the hokderness 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.

The exposed chalk of Flamborough provides examples of erosion, features such as caves, arches and stacks. The Holderness Coast is a great case study to use when examining coastal processes and the features associated with them.

What is plan to defend the terminal against the sea? Mappleton is an excellent case study of an attempt at coastal management which has a negative impact further along the coast.

  HONORS THESIS PROSPECTUS TULANE

The Holderness Levfl is in the North of England and runs between the Humber Estuary in the south and a headland at Flamborough head. A number of farmers have lost a significant amount of land to increased rates of erosion. Revetments are very expensive but long-lasting. 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.
