In the British Isles Coastal Areas Have Always Attracted Settlement.

Extracts from this document...

Introduction

In the British Isles coastal areas have always attracted settlement. People come for a holiday or they might have a second home by the sea. Many retired people also live near the sea, seeking a quiet and refreshing place to spend the rest of their lives. Tourism has also spread up the coastline bringing more people and so more resources have been set up to accommodate them. Pathways have been built along the coast to bring easy access to the tourists. However, along Britain's coasts, erosion is taking place which potentially destroys cliffs, houses and moves beaches. Coasts are managed to keep the sea out and to keep the beach in. In 1990, Mappleton was under threat from losing 30 houses along the coast of Holderness. Its main road would've disappeared into the sea and would be very expensive to rebuild. So, a coastal management scheme was set up. Blocks of granite were imported from Norway so two groynes could be built. This would trap the beach sediment that is being eroded away due to longshore drift. This would then absorb some of the energy from the waves so less energy would be directed on the cliff's side. ...read more.

Middle

In Scarborough, there are sandy beaches on either side of the headland, both of which tourists visit. Behind the beach there is a promenade and kiosks selling drinks, ice cream and other beach necessities. They already have a large sea wall, which runs the full length of the bay. In 1993 a famous hotel collapsed as the cliff beneath it gave way. The sea wall has proved being very effective here in Scarborough and no other method of coastal management has yet been advised. Dawlish Warren has a sandspit, which is used for nature reserves and as a nice place to walk upon. A sea wall at the southern end of the spit protects the railway from falling to it the sea. The chalk cliffs are being battered by corrasion and are forming caves and stacks which weaken the cliff and it eventually falls down. A breakwater reduces the energy from the waves and ensures less energy hitting the cliffs therefore less erosion. A wave-cut platform is visible at low tide, that much of the cliffs have been eroded already. ...read more.

Conclusion

Not because they are less expensive, in the contrary they are more efficient. These all absorb most of the waves energy and this prevents excess erosion. The gabions, stones in wire brackets, and the concrete revetment are ugly and will cause people not to come to your beach rather than to come. The beach nourishment hasn't been performed by any of the examples mentioned and this is because it is only useful in the short term, not in the long term. Once you add more sand the wind or sea will take it away again. Coastal management is important especially if someone's home or job is at risk. If tourism is the only means of income in the town then saving the beach would be appropriate. However, if you interfere in nature something will always happen to get back at what you did. With the groynes, they will be stopping all the sediment going further down the coast, and they will be experiencing extra erosion because the waves won't have anything to absorb the energy. It is best to do nothing, just have a beach that will absorb the energy. Care will have to be taken in storms, however not very many people can interfere with nature and get away with it! ...read more.

    This was because there is more material being transported to Hulstone Point. This is due to long shore drift transporting the pebbles up the beach to Hulstone beach.

    The process of attrition will erode the pebbles. Hypothesis 2: A decrease of pebble size in the direction of long shore drift, again attrition is involved.

  1. How and Why is Sheringham Protected from the Sea?

    Tidal range (tides are discussed in more detail later on) is an important factor as it determines the vertical height over which this erosional process can operate. The mean tidal range is about 4m at Weybourne and decreases to the east, dropping to about 3m at Happisburgh.

    Longshore Drift Longshore Drift is the process of sediment is moved along the shore. It happens when waves break at an angle to the beach and carry sediment across instead of straight back out. Investigating whether longshore drift occurs on both the North and South beach is another way of looking at the differences between either beach.
