Managing coastal erosion, Holderness

Extracts from this document...

Introduction

Coasts-Case studies Managing coastal erosion, Holderness The Holderness coast lies between Flamborough Head and Spurn Head and is one of the fastest eroding coastlines in Europe. The average rate of erosion is 2 metres per year. Over 30 villages and 26 towns have fallen into the sea since roman times. There are lots of erosion features along the Holderness coast. The coastline is made of soft clay which experiences rapid erosion. In addition, longshore drift moves south along the coastline so there is little opportunity for beaches to become established in front of the cliffs The erosional landforms evident along the coastline are varied. ...read more.

Middle

A concrete sea wall protects the town from flooding. Groynes ensure that the sand and shingle beach is not washed away by long shore drift. Mappleton Mappleton is a village 3km south of Hornsea. The village has been exposed to rapid coastal erosion at the rate of 2 metres per year. Two rock groynes and a rock revetment have been built here; this meant a beach accumulated between the groynes, providing a barrier against the erosion. Unfortunately, the groynes are preventing sand from reaching the coastline south-causing more coastal erosion there. Case Study: Blackpool Blackpool has a population of over 146,000 and is one of the most popular seaside resorts in Britain. ...read more.

Conclusion

They built 100 groynes which trap beach sediment on the up drift, each groyne cost �200,000. This helped quite a lot but to ensure that he least possible amount of erosion would take place they decided to invest in beach nourishment schemes. If there were no coastal defence schemes, it would have taken 5-10 years for the beach to disappear. This would have caused a great effect on the economy and affected businesses and people everywhere. It is quite shocking how people are affected by the power of the waves. This is why the government has to make sensible decisions in order to protect the coastline from retreating inland. ...read more.

    In waves, individual water molecules move in circles. There is little forward motion of the water; it is the wave that moves forward. As waves approach shallow water the circular movement of the water molecules is impeded by friction from the bottom. The water at the top of the circle therefore is not supported by more water and it moves forwards into thin air.

    This was to allow further sediment transport. Increasing coastal protection measures became effective in Sheringham.

The Sea wall also serves a purpose as a promenade.
