Introduction

Is there any evidence of coastal erosion or deposition along this section of the north east coast? In order to answer this question I must find as much evidence as I can for coastal erosion and deposition The table below shows what I expect to find Features of coastal Erosion Features of Deposition Caves Spits Cracks Bars Stacks Beaches Stumps Arches To ensure I answer this question fully I needed some background information about coastal erosion and deposition. Coastal erosion is the process where the sea wears away at the land. It happens because of four processes Hydraulic action Attrition action Corrosion action Corrasion action (See Glossary) A wave cut notch is where the waves wear away at the cliffs and make a notch in them. A wave cut platform is a bit of rock which has been flattened by the waves and made into a platform. Water gets into a crack in the cliff and expands, pushing the crack sides until they break down and it becomes a cave. The water in the cave continues to push back and eventually all the way through into an arch. After erosion, and storms, weathering etc the top of the arch wears away and breaks down and creates a stack which then makes a stump. Crack-Cave-Arch-Stack-Stump Coastal deposition is when the sea carries material and deposits them somewhere else. They are moved by long shore drift. (See glossary) I had to look for evidence of coastal erosion and deposition. The following lists my methods. Methods Why Observation To see things Photography To provide evidence Field sketches To show evidence Estimation Easier to carry. Easier and safer to use Table recording Quicker Note taking Support my methodology We did see some evidence for coastal erosion and deposition in the form of arches, stacks, caves and cracks. ...read more.

My expectations were to see the numbers get smaller as the distance from the cliff increases. I collected my data in spring with clearer weather conditions The following pages show my results in tables, and then in graphs I have used the 3 dimensions to calculate the volume of the sample. I used the volume because it gives me a representation of the mass of the sample and mass is what affects the amount of transportation of the sample. I may change from volume to area in several places but they all mean VOLUME.

But there are several points which do not fit the pattern. At 6metres and 8metres away the area is much larger than elsewhere. These points show inaccuracy, and in a way show my prediction wrong. On the graph to show Trow point there is an overall show that the results drop as distance increases, but the last point is not in the pattern. It is higher than 400, the rest are below 200. This also contradicts my prediction. The graph of the beach near Souter lighthouse is quite the opposite of what I expected. ...read more.

Conclusion

Results Location 1. At this location there weren't any real signs of recreational use but the grass was neatly trimmed and a public walkway with drainage was visible. There was Souter lighthouse also. Location 2. At Marsden rock there was quite a lot of evidence for recreational activity There was a pub called Marsden grotto (refer to information page) built into the rocks. There were many steps from the cliff top to the beach. The Marsden rock is a big tourist attraction. The headland is cared for with a public walkway. Location 3. There were large rocks purposely placed for viewing, a small beach also. ON the headland there is a seat bench, and neatly cut grass with railings and a nice view. This area appeared to be for walks and cycling. Location 4. This area has two large beaches frequently used by public. It had pubs on the sea front like sundial and a large pleasure park and the rattler public house. There were 2 parks on with pedalos and children's items and the other which is used for a large festival. Interpretation Looking at the locations we visited I think there was not very much evidence for recreational activities at points 1 and 3. There were simply the footpaths. At location 2 there was evidence for both tourism and recreational activities with Marsden grotto. At location 4 there were many examples of recreational activities like the 3 parks and Pleasure Park These were major tourist attractions also. This area didn't have much evidence for these on the whole. Evaluation If I was to answer this question again I would maybe contact local authorities and ask them about different recreational activities and tourist attractions. I would also study the locations in more depth and possible a tourist count. I think this wasn't a very successful answer to the question maybe due to lack of information. ...read more.

    The main reasons for coastal management are: - To protect the coast from the erosive effects of the sea. - To increase the amount of sand on the beach. Many strategies have been tried around the world, and these can be divided into two main groups, hard and soft engineering.

    This is because we didn't spend ages counting up every different species or looking closely to see if any little plants were growing very low on the ground. We also went to Yorkshire in September and so the season must be accounted for - spring and summer are the best
