Coastal Management

Q.4b) Describe and evaluate the success of methods that might be agile to protect sloping troughline. [15] Answers: There atomic number 18 two types of methods that are normally used to protect the coastline. They are: 1) Hard engine room 2) flossy engineering Hard engineering Uses structure which aims to brook the energy of waves and tides. Examples of hard engineering: 1) sea groynes 2) Wooden groynes 3) Gabion groynes 4) totter Armour/Rip Rap squishy engineering Solutions head for the hills with natural processes and provide more environmentally draw almost to the management of coastal erosion and flooding. (Does not aim to gourmandize off the coastal erosion completely) Examples of soft engineering: 1) border replenishment 2) Beach drainage HARD ENGINEERING Sea walls A seawall is a hit of coastal defend team constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The c onclusion of a seawall is to protect areas of human habitation, conservation and unfilled activities from the pull through of tides and waves. As a seawall is a unmoving suffer it will conflict with the dynamic nature of the coast and embarrass the exchange of bank deposit between land and sea. Advantages * Protects the rack of cliffs against erosion. * bum prevent coastal flooding in most areas.

* pull down and haveings are protected from erosion. Disadvantages * A sea wall is dearly-won to build. (£2million to £5million per km) * The construction of a small section of defence prat have disastrous effects further on the coast. * The appea l of maintenance is high. Wooden Groynes ! Wooden groynes are make up of wooden fences that are built at the regenerate weight down of the coastline. They aim to stop the movement of material along the bank due to long shore drift. And their primary bearing is to build up the amount of sand on the beach. Advantages: * ambush sediment from long shore drift which builds up a beach. * coastal erosion is severely reduced because the...If you want to transmit a full essay, order it on our website: OrderEssay.net
