 DME- The Holderness Coastline.

Introduction

        The Holderness Coastline is eroding much faster than any other coastline in Britain as it is made from boulder clay. 100,000 year ago an ice sheet covered parts of Europe pushing with it sand, shingle and rocks (this made up the boulder clay).  The boulder clay was left by the city York when the ice sheet retreated. This made the Holderness coastline.

        Many people immigrated to the Holderness Coastline as the boulder clay was good for farming as it was much softer than other lands. Throughout the years the coastline has been eroding away effecting many towns and villages. Barnston village is being worn away as there is nothing of great importance there. Mappleton town on the other hand has rock groynes costing £10000 each to protect the town. Cowden farm is being worn away as a result of the groynes at Mappleton village; there is no sand or shingle from long-shore-drift travelling to protect the cliff. It is now eroding away 30f per year. In Withernsea is being defended by a £6000 per meter sea wall made of concrete to protect the town. Eastington gas terminal is at Holderness coastline as it is the closest to oil, as the coastline is eroding quicker than they expected they are putting boulders, costing £3500 per meter, in front of the cliff to reduce the force of the waves.

        Some places at the Holderness coast are better protected  than others, as protecting the whole of the coastline would be very expensive and pointless, as some places are more important than others. Some of the sea defence schemes used on the Holderness coast are: Rip-rap (boulders) coasting £3500 per meter are large interlocking man-made boulders that protect the coast by braking up the waves. Large boulders are strategically placed at the back of the beach to act as a barrier to brake up the wave and dissipate its energy. It can be effective, but a source of visual pollution- this ...
