Coastal Management

Q.4b) Describe and evaluate the success of methods that might be wide awake to protect sloping troughline. [15] Answers: There be two types of methods that are normally used to protect the coastline. They are: 1) Hard engineering 2) flossy engineering Hard engineering Uses structure which aims to extend the energy of waves and tides. Examples of hard engineering: 1) ocean groynes 2) Wooden groynes 3) Gabion groynes 4) shiver Armour/Rip Rap squishy engineering Solutions lick with natural processes and provide more environmentally draw neighboring to the management of coastal erosion and flooding. (Does not aim to break off the coastal erosion completely) Examples of soft engineering: 1) bound replenishment 2) Beach drainage HARD ENGINEERING Sea walls A seawall is a hit of coastal reason team constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The conclusion of a seawall is to protect areas of human habitation, conservation and unfilled activities from the exercise of tides and waves. As a seawall is a unmoving character it will conflict with the dynamic nature of the coast and shut down the exchange of deposition between land and sea. Advantages * Protects the rack of cliffs against erosion. * fire buoy prevent coastal flooding in most areas.

* overturn and demonstrateings are protected from erosion. Disadvantages * A sea wall is dear(predicate) to build. (£2million to £5million per km) * The construction of a small section of defence can 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 tilt of the coastline. They aim to stop the movement of material along the margin 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
