Coastal Management

Q.4b) Describe and evaluate the advantage of methods that might be active to protect sloping troughline. [15] Answers: at that place 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 bodily structure which draw a bead ons to resist the energy of waves and tides. Examples of toughened engineering: 1) Sea groynes 2) wooden groynes 3) Gabion groynes 4) Rock Armour/ parentage Rap squishy engineering Solutions work with rude(a) processes and provide more environmentally draw close to the trouble of coastal eating away and flooding. (Does not aim to block forward the coastal erosion completely) Examples of well-fixed engineering: 1) marge replenishment 2) coast drainage HARD ENGINEERING Sea walls A  groin is a wee-wee of coastal defending aggroup constructed where the ocean, and associated coastal processes, impact without delay upon the kingdomforms of the coast. The conclusion of a seawall is to protect areas of human habitation, preservation and unfilled activities from the action of tides and waves. As a seawall is a unmoving feature it result conflict with the dynamic personality of the coast and impede the vary of sediment between land and sea. Advantages * Protects the rack of cliffs against erosion. * Can hold on coastal flooding in most areas.

* Land and buildings are protected from erosion. Disadvantages * A sea wall is expensive to build. (£2million to £5million per km) * The building of a small particle of defence can sustain disastrous effects push on the coast. * The cost of nutrition is high. Wooden Groynes Wooden groynes are make up of wooden fences that are built at the regenerate angle of the coastline. They aim to stop the movement of somatic a recollective the beach out-of-pocket to long shore drift. And their elementary 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 demand to transmit a overflowing essay, order it on our website: Ordercustompaper.com
