Walton on the naze coursework

Extracts from this document...


SAMUEL COLE 5C HOW EFFECTIVE ARE COASTAL MANAGEMENT TECHNIQUES AT WALTON ON THE NAZE? The aim of the coursework is to find out how effective coastal defences on the north and south beaches at Walton on The Naze, Essex. We have knowledge that the north beach is unprotected, whereas the south beach is protected by man made defences. The naze has been chosen, because it shows a coastline which is eroding very quickly and is also relatively close to our school. A comparison can be seen between the two sides i.e. The North beach appears to show cliffs that are eroding very rapidly, whereas the south beach erosion is less apparent. Two beaches differ significantly and therefore make a fine area to do the coursework. These questions will be asked to help reach a conclusion: --What evidence is there to show that erosion still takes place? --What evidence is there that long shore drift is taking place? --Do the coastal defences on the South Beach affect the North beach? --Is there a noticeable effect of longshore drift on the coastline?

Diagram showing slumping cliff on North Beach Protection comparison: North and South beach North Armour blocks are indeed one type of protection on the North side.They are relatively cheap but are environmentally unattractive. If they are resting on sand and shingle they can also be undermined by waves. There are no sea walls or groynes built on the north side. Minor plantation is seen on the cliff face. There are also apparent cracks in the wall. The cliff faces were indeed battered and bruised and there were signs of slumping. This apparent lack of protection, is a fundamental factor for the cause of the rate of which the North beach is eroding. Rip Rap South Recurved Sea Walls are expensive to build and may cost up to �1million per km. They are designed to stop erosion but his also means that there is less sediment to protect other stretches of coast. They reflect wave energy, and as a result of this, the waves scour base of sea walls undermining them so that they eventually collapse. Groynes stop longshore drift and keeps the beach in place. Basically the idea of a groyne is to prevent longshore drift. Groynes are very useful and are the cheapest and most effective way of protecting a cliff and the beach behind it. ...read more.


This is because this area of the beach collects the most amount of material. The beach material piles up because there is no other route for the beach material to escape to. We can also see that the further we go north,the greater the difference becomes.Thus we can assume that longshore drift is getting stronger as we go north. The North side also had a greater deposit and therefore proves again that the direction of longshore drift is northerly.

  1. Coastal erosion problems in Walton on the Naze

    Data collection. 1. This section is going to include my findings from my field trip to Walton on the Naze, this will include; a map, groyne measurements, field sketches of managed and unmanaged coastline, photos, questionnaires of peoples attitudes, cross section along transects of defended and undefended coastlines and secondary sources of information.

  2. "An investigation into the methods of coastal management along Brighton's Coastline and the reasons ...

    The measurements had to be completed, where the waves break on to the beach. A total of four people were needed to absolute the conduct experiment. The first two people placed a ranging pole of the groyne so that half the ranging pole stuck out the end of either side of the groyne.

  1. Investigate changes in beach characteristics with increasing distance along the shore, Walton on the ...

    the maximum fetch and prevailing wind are both from the south-west, there is predominantly eastward movement of beach material. However brief changes in wind and therefore wave can cause the movement of material to be reversed. When the wave breaks, the swash carries material up the beach at the same angle as that at which the wave approached the shore.

  2. Is Dawlish Warren is threaten by human impacts and marine processes.

    Marram grass can be transplanted from areas where it is growing well to 'blow outs' or areas of sand, which need protecting. Sand traps are often built to collect sand and rebuild a dune in areas where vegetation destruction by trampling combined with wind erosion has led to the formation of a blow out.

  1. Find out the geological appearance, structure and composition at Peacehaven, Newhaven and Rottingdean.

    They are both made up of chalk, sandstone and clay, although there is considerably more clay. They are both inactive cliffs so no examples of erosion will take place here. They both have faults, joints, bedding planes and lines of weakness.

  2. Does management affect coastal processes at Walton-on-the-Naze?

    Hard engineering is physically building something e.g. a Sea wall. Whereas soft engineering e.g. planting is a far more natural management process. We as humans can only militate the worst effects of flooding, that is to say that floods are always going to happen, we cannot stop them.

  1. Erosion at Walton on the Naze

    Physical Weathering. Fig 4. Chemical Weathering. Fig 5. Biotic Weathering. Fig 6. Mass movement is another reason for coastal erosion at Walton. It occurs due to: - 1. Gravity, 2. Water, 3. Opening of joints, 4. Internal rock pressure, 5.

  2. Investigate the difference in density of limpets on a sheltered rocky shore and on ...

    We see this trend because the abiotic conditions experienced by the limpets are a lot more favourable to their existence and so the numbers would increase. At Frenchman's steps we find that wind does not affect the limpet to much as the aspect is away from the prevailing wind.
