Walton on the naze field trip coursework

Extracts from this document...


Walton-on-Naze. To complete the case study, we went to Walton-on-Naze to find out ways in which the coast is currently being protected from erosion. We also looked at the effects caused by the erosion on the Walton coast. By doing this, we could come up with ways that the coast could be protected further in order to keep it there for the future. The coastline at Walton faces East (compass direction) towards the North Sea. The cliffs are orange in colour and steeply sloping. At the top of the cliffs is a thin layer of grass covered in cliff top vegetation. In the cliffs you can see sand and shingles. At the base of the cliffs is a broad stretch of beach consisting mainly of sand. To the North the coast is interrupted by the river orwell. On the northen side is the port of Harwich. There is a large breakwater here called land guard point. ...read more.


Our average at the end of the experiment was 15.1 waves breaking per minute therefore the waves at Walton are destructive. We could clearly see the cliffs had been eroded due to the pillboxes that were on the sand. Around 60 years ago, the pillboxes were on the top of the cliffs, so this shows that the cliffs beneath the pillboxes had been eroded gradually over time. You could also tell from this where the cliffs once were and how much they have eroded since then. From seeing this, I think that in about 40/50 years time, the land and facilities that are on the cliffs will totally disappear down to erosion. By examining the cliffs and sampling it, I could see that the cliff material was made up of mainly, small pebbles, sand, shingles and London clay. They were quite dark coloured with oranges, yellows and browns. There was several layers, that were all mixed colours, some with vegetation growing from it and parts with no vegetation at all. ...read more.


Here is a diagram of a spit. When in West Mersea, we looked at the number of sea defences used there. One sea defence used was Groynes. We also did an experiment to determine the direction of long shore drift on the beach. To do this we had to measure 3 different Groynes along the beach on both sides and 3 different positions along the Groyne. The side that was the smallest was the side that long shore drift deposited its material. Therefore that's the direction it is going. I believe more can be done to protect both Walton and Mersea's coast. In order to sustain the tourist attractions and the amount of money coming in to run the businesses, they both need to be protected from erosion. If nothing more is done about the risk of erosion, slowly over time, the land will disappear and the houses and shops will collapse. People will lose their homes and businesses, therefore the whole area will be losing money. ?? ?? ?? ?? Geography field trip. Olivia Clark ...read more.
