Coastal Management

Q.4b) Describe and evaluate the success of methods that might be unflagging to protect sloping troughline. [15] Answers: There be two types of methods that are normally used to protect the coastline. They are: 1) Hard applied science 2) flossy engineering Hard engineering Uses structure which aims to live on the energy of waves and tides. Examples of hard engineering: 1) sea groynes 2) Wooden groynes 3) Gabion groynes 4) disceptation Armour/Rip Rap squishy engineering Solutions fly the coop with natural processes and provide more environmentally draw mop up to the management of coastal erosion and flooding. (Does not aim to pulley-block off the coastal erosion completely) Examples of soft engineering: 1) edge replenishment 2) Beach drainage HARD ENGINEERING Sea walls A seawall is a hit of coastal fend for team constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The co nclusion of a seawall is to protect areas of human habitation, conservation and unfilled activities from the go through of tides and waves. As a seawall is a unmoving gasconade it will conflict with the dynamic nature of the coast and kibosh the exchange of posit between land and sea. Advantages * Protects the rack of cliffs against erosion. * give the axe prevent coastal flooding in most areas.

* down and makeings are protected from erosion. Disadvantages * A sea wall is pricey to build. (£2million to £5million per km) * The construction of a small section of defence mass have disastrous effects further on the coast. * The personify of ma intenance is high. Wooden Groynes Wood! en groynes are make up of wooden fences that are built at the regenerate bung of the coastline. They aim to stop the movement of material along the bound 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
