Birling Gaps and Eastbourne's coastline.

Extracts from this document...

Introduction

Introduction My project is on Birling Gaps and Eastbourne's coastline. Their grid references are 553,960 (Birling Gap) and 630,003 (Eastbourne). These are both situated in the south east of England on the south east coast. The reason we are doing our work on these particular places is that these places have a recurring problem. Erosion. Birling Gap and Eastbourne are both areas of coastline along the south east of England. We are focusing on these areas because they are areas, which the cliff-face is being eroded away. The erosion is happening at an incredible rate. This is because the cliff is made from chalk, which is a soft and easily eroded rock. Also, another factor affecting the erosion on the cliff is the fact that there is no coastal protection. This is because it is only a small hamlet and has only a few cottages in it. Birling Gap has quite a lot of history to it, a long long time ago it wasn't by the sea. ...read more.

in the picture has been removed from the sea and moved further back. This process is called managed retreat. Managed retreat is moving an object back from the sea to prevent it from falling in. It is not allowed to let buildings fall into the sea. This is expensive but necessary. This particular job cost in excess of �250,000. Photo of a wave cut platform and the lighthouse. Task Having completed my fieldwork, I am being asked to structure a report, which will attempt to challenge the hypotheses that state - 1. The pattern of beach material along the coastline reflects natural beach processes. 2. Destructive beach profiles are steeper in gradient than constructive beach profiles. 3. Some parts of the East Sussex coast are managed better than Birling Gap. 4. Coastal management decisions do not reflect the land use of the surroundings. Method At each location I needed to collect information such as the name, grid reference, draw a field sketch, write a site description and find out the issues concerning coastal management. ...read more.

Conclusion

to natural processes. Because if you look at figures 1 and 2 you will see that Birling Gap has a weak positive correlation and Eastbourne's results are all over that place with no correlation. This shows that the average rock size it completely different at Eastbourne because of the way the council always has to move the shingle around to help manage the beach properly. Hypothesis 2 I found out that the gradient for: Birling Gap - 1:8 Eastbourne - 1:7 I got these results from my beach profile graphs. (Shown below.) These graphs show the definition of the beach. Also, I counted the waves at both places. Constructive waves are waves that break every 9-10 seconds (6-7 a minute). Destructive waves are waves that break more frequently (12-15 waves a minute). At both places the wave count was high rendering them destructive waves. The table of results for the wave count is below. Minutes Waves Birling Gap Eastbourne 1 15 21 2 13 15 3 12 16 Destructive waves have a strong backwash and transport material on the beach into the sea. The beach material that goes into the sea leaves a steep gradient behind. ...read more.

  1. Coastal Processes

    The heaviest and largest material is left near the cliff. The sea moves, grades and deposits other material according to size away from the cliff so the finest material is deposited as sand off the coast. The material produced by weathering and erosion is moved by waves along the coast and out to sea.
