Extracts from this document...


INTRODUCTION 'Which of various proposals suggested could be used to address the problems of erosion at Col Huw?' I will consider the background to the problems being experienced at Col Huw due to coastal I erosion before evaluating the strategies proposed to protect the public, buildings and recreational facilities. Field work study area Col Huw is at the extreme south of South-West Wales (see map 1) in the county of Glamorgan. It is a low lying coastal plain. It contains alluvial deposits from rivers draining south into the British Channel and glacial deposits which are easily eroded. The British Channel has the world's second highest tidal range (11metres) so the coast line is liable to suffer extensive erosion. Different people have different opinions of whether the coast is worth being protected or not. Regularly arranged revetments are currently being used to absorb the energy of the waves so the effect of the sea eroding the coast is less. (picture) (Map 1) Aims and Objectives The aims are to: 1. Find out about the problems of erosion. 2. To find out the way in which the sea erodes and how the cliff is particularly susceptible to different types of erosion, and why. 3. To find out the different reasons for which the coast needs to be saved. 4. To conclude the best possible solution to address the issue. The suggested proposals are: a) Do nothing. b) Upgrade Existing Defenses and Set Back Car Park and Access Road. c) Protect Whole Frontage with Linear Revetment. d) Shore-connected Breakwaters and Reduced Linear Revetment. p.17-20 shows these and a prediction of recession after 30 years. The predicted costal changes are marked in coloured pen. Risk Assessment Strong waves may strike the shores and cliffs may collapse or stone fall. Therefore the following safety precautions must were taken AT ALL TIMES: -STAY with the group and staff, and do not make explorations on your own initiative unless you have the explicit permission of the staff. ...read more.


Do you think that this coast id worth being saved? Yes, but it was a big mistake to put the boulders there. Since we've been coming here we've noticed that the sands that were once here have all gone. There have been a lot of major changes in this area since we started coming! 2. Sex: Man Age: 40-50 Are you local? Yes How did you travel here? By car How long have you been coming to this sight'? About 10 years Do you come here often? I come about 1-2 days every week, for 2 hours. When the children when younger we used to come for up to 4hours, so they could play here. They grew up on the beach really and they spent much of their time here. It's great for children. Why do you come here? I love the sea, and the beach's general unkeptness, it's not commercialized, and the coastline is absolutely beautiful. Do you feel that the coast line is being saved? No Why Not? Well I used to work on the council, and I was on the committee when we were attempting to decide on what action to take. The council; have no vision of what they want the coastline for. They don't know if it is a sight of natural beauty, or a public area. If it's to be public, 3. Caf� owner Where is the new cafe meant to be built? Just in the back field, where all the chairs are at the moment. It's further back from the coast, and once we've built it we plan on paving over the area of the current cafe to use that as the picnic area. Have you got planning permission yet? No, the heritage coast thinks that it'll dominate the area, and it's meant to be an area of natural beauty, not industrialized! The council have given themselves planning permission to have the council lifeguards area moved back, but they won't give us planning permission to move our business back. ...read more.


The caf� and lifeguards have to be protected. Also the car park is being eroded. The facilities have been built on the flattest, newest and weakest deposit which the sea is now attacking. The cliffs also need to be protected as they are a special type of cliff which is a rare site. Surfers also come here as there are good waves, so the coast needs to be saved for their use. There is also a nature reserve which needs to be protected. You can not please all of the people all the time, you can only try to please the majority. So evaluating all the data I conclude that option 'B' is the best proposal suggested that could be used to address the problems of erosion at Col Huw. Evaluation My field work went well. I did a good amount of coastal study in the time that was available. I came away with a broadened knowledge of coastal processes and the activity of the sea. I could have studied high tide. I would have seen what happened in the way of erosion during this period. I could have been in a boat off shore and observed these processes. However, there were time constraints. I could have studied how different parts of the cliff were eroded because the head land is less resistant than the liassic limestone. However, close study of the cliff base was not possible due to safety measures which had to be made. From looking at fossils in the rock I could have found out its species and dated that part of the cliff. This is because different bands at different heights have different species of fossils as they were laid down at different time. I knew that there were fossils in the rock as it was limestone. I was only able to look at broken fragments at the bottom of the cliff, these could have fallen from any part of the cliff. Over all it was a worth while experience for me and I enjoyed the coastal field work which I participated in. ...read more.
