To what extent should Walton-on-the-naze be protected from the sea?

Extracts from this document...

Introduction

Introduction In this piece of coursework I am studying Walton-on-the-naze. I will decide at the end of this piece of coursework to what extent Walton-on-the-naze should be protected from the sea. Walton-on-the-naze is a part of the east coast of England which is situated in Essex. It sticks out and faces the North Sea. The title of this project is about what extent Walton-on-the-naze should be protected from the sea. The title is basically asking for me to take a side, do I think that the sea should be left to take a natural course or should Walton-on-the-naze be protected from the sea. I have then got to explain my reason for my views. Chapter 1 (What is the naze like?) In this chapter I will be discussing what the naze is like. I will be describing what land uses there are, what the landscape is like and what geology there is behind Walton-on-the-naze. There is a land uses map on the next page of this project, it is basically illustrating the land uses Walton has in birds-eye view. Land uses: There are many different land uses for Walton-on-the-naze; there are residential uses, recreational uses, services, a nature reserve, agriculture, tourist shops, and industry. The residential uses in Walton are all the homes that have been built in the old coastal town, such as the beach houses built right by the coast. Recreational uses in Walton are; the tourism and amusements such as the naze nature reserve. Services in Walton include a sewage works, a nature reserve, and local police stations. There is also a Sight-of-specific-interest (SSSI) in Walton-on-the-naze. Sea defences have been built to defend parts of Walton in hope of saving the small coastal town. The sea defences were mainly built in the past to maintain land back in the days of war when a lot of Walton was used, and still is used for agriculture use. ...read more.

Middle

Short life (about 20 years) ? If long-shore drift is poor than down-drift starvation will happen Sea Walls: There are two types of sea walls; vertical sea walls and curved sea walls. Both walls are made of either masonry blocks or concrete, and both sea walls are made of impermeable material for obvious reasons. A vertical sea wall is a solid, vertical structure with strong foundations. The vertical sea wall breaks up waves by absorbing most of their energy. If you look at the Vertical sea wall diagram below then you will sea a fair amount of wave splash back enters land, although once the waves hit the sea wall most of the energy is lost. A curved sea wall is like a vertical sea wall, apart from the fact it has a curved lip and a curving ramp. The idea of a curved sea wall is that the waves are thrown back because of the ramp and curved lip. The waves that hit the curved sea wall therefore do not get thrown over the wall but are pushed backwards with gravity spreading out their energy. If you look at the curved sea wall diagram below you can see the blue dots which represent invading waves travel up the ramp to then become red dots which represent retreating waves. This process stops the wave splash entering land opposed to a vertical sea wall. Advantages: ? The massive structure can withstand severe wave-action ? Sea walls have a long-life Disadvantages: ? High capital costs ? Sea walls decrease beach permeability Breakwater: A breakwater is a solid, man-made, masonry faced concrete cap that is based in rock foundations. It will get overtopped at high tide but it is primarily designed to break and weaken waves rather than stop them passing altogether. If you look at the diagram below you can see that a breakwater can be used as a groyne too. ...read more.

Conclusion

Also the SSI will be revealed more if further protection isn't invested which means you will get more fossil hunter tourists. Also without having protection you don't cause the long-shore drift problem which causes other areas to suffer from down-drift starvation. Another benefit of stopping the investments for protection is that you get to see more picturesque views rather than unsightly views. Finally High costing means Walton is loosing more money than it needs to. Walton will be able to fund itself a lot better without paying protection prices. After analysing reasons for and against further protection I have come up with the conclusion that Walton should not have anymore protection invested. I say this because the protection investment costs are too high, and even if you kept investing in protection than the protection will fail in a very short period of time due to rising sea levels and the fact eastern England is sinking. Investing in further protection would mean that you save more wildlife and the English heritage that exists at Walton, but is it really worth splashing out so much money just to preserve a little piece of history. You have much more history in Britain; the tower is only one little thing, yes the tower brings in a few tourists but the cost of more and more protection will be much higher than income from tourism. The only main issue with not investing in more protection is the housing, the housing should be ok for a while but eventually the housing will be lost. To summarise not investing in more protection means; that you let nature take its natural course, it also means that you save Walton a lot of money which it needs to maintain itself. Also the SSI will be revealed more and more. So in conclusion I think that no more protection should be invested at Walton, but the protection that already exists should be maintained. ?? ?? ?? ??

    I believe there will be more sediment on the managed section because groynes will trap sand and rock material there. A reason for this was the process of long-shore drift - which is interrupted on the managed section. As sediment and fine sands will be trapped here, less of this

    Hydraulic action is also a form of erosion, it is the sheer weight and force of water acting upon the sediments, this is important to my investigation as after we concluded our experiment, the tide came in, acting upon the sediments.

    The distance was then measured by another member and the results were recorded. We repeated this three times and then came up with the average. The average was 6.53 metres. Another experiment we did was counting the number of waves each minute for 10 minutes.
