Coastal Erosion and Protection.

Extracts from this document...


´╗┐Geography Homework By Max Hesketh Part 1 ? Explain why some coastlines are eroded more quickly than others The main factors that affect the rate of coastal erosion is the geology the coast, direction of the prevailing winds, type of waves surrounding the coast, the coastal management strategy and its likelihood of being prone to sub aerial weathering. All these aspects will determine and test the coastlines overall durability. When situated in a real life situation it becomes clearer to understand why some coastlines erode faster than others. For example, the geology the happisburgh coast is very weak, as it includes sandstone layered onto clay. ...read more.


Initially the attempts were thought a success, however after some years it was realised that the power of the sea and waves could overcome human attempts. Only could protection be a success if huge costs were going to be involved. Many methods around the British Isles have taken place in he last 50 years with many failures occurring. It is very rare to find a coastline that shows a decrease in the rate of erosion over many years after defences are in place. In fact in places the defences seem to have speeded up the erosion process. Coastal erosion is a natural process of erosion, transportation and deposition, interfering with this balance could be to blame for the rise in erosion on the coasts of some areas. ...read more.


Part 3 ? Coastal management (Soft Engineering, Hard engineering) My choice ? Soft engineering In civil engineering of shorelines, soft engineering is the use of ecological principles and practices to reduce erosion and achieve the stabilization and safety of shorelines and the area surrounding rivers, while enhancing habitat, improving aesthetics, and saving money. Soft engineering is achieved by using vegetation and other materials to soften the land-water interface, thereby improving ecological features without compromising the engineered integrity of the shoreline or river edges. There are also economic benefits associated with use of soft engineering. In general, soft engineering of shorelines is typically less expensive than hard engineering of shorelines. Additionally, long-term maintenance costs of soft engineering are generally lower because soft engineering uses living structures, which tend to mature and stabilize with time (E.g Dune regeneration). ...read more.

  1. What should hapen to Happisburgh?

    Do nothing - this would mean leaving the coast to erode as it has been doing so for 12,000 years now. It would be free, of course, but residents wouldn't be too happy. In order to decide which option was the best for the council to do, I did a cost-benefit analysis of them.

  2. Cliff erosion in East Sussex - the processes, problems and solutions.

    Money Saved Cost of Protection However the costs of all of these defences are very variable and so a true coat benefit analysis cannot be carried out as there is no specific site. Managed retreat is certainly the cheapest but it does not actually protect the coast.

  1. What should happen to Happisburgh?

    To move one family away would cost over ´┐Ż100,000. Therefore, to move a whole village would be far too expensive. Also regarding money is the option to stop all development. If this was to be done, money from developments which could be built there would be lost. Moving people away presents many problems.

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

    Marsh: I don't think this type of protection has been very successful at Walton. Although it is free, natural protection it doesn't really defend land behind it at high-tide when all the water comes in. Beach replenishment: This type of protection has been quite successful because the beach is the

    Rip rap is basically a lot of rocks scattered along the beach in order to absorb the energy from very strong waves and breaks them before they reach the cliff base.

    Different types of coastal erosion Corrasion/abrasion is when waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff. When waves hit the base of a cliff air is compressed into cracks. When the wave retreats the air rushes out of the gap.
