Llandudno Concrete groyne Sea wall built to Stop town from flooding
How can coasts be managed? <ul><li>There are two reasons why councils spend so much cash on protecting the coastline in certain areas… </li></ul><ul><li>First – To keep the sea out and protect homes and businesses </li></ul><ul><li>Secondly – To keep the beach there to maintain the tourist trade. </li></ul>
To keep the sea out ….. Build a sea wall to deflect the power of the waves away from the seafront. However - Lots of maintenance needed and they are expensive to build. The Catch - Councils will only pay for them if there are many people and much property to defend.
Area not protected and deemed unworthy of saving.
To keep the beach there … <ul><li>Groynes and breakwaters are constructed at right angles to the beach </li></ul><ul><li>These trap sediment and stop longshore drift. </li></ul><ul><li>They also protect the beach from powerful storm waves – stopping erosion of beach material and cliffs. </li></ul>
Neighbours from hell … (not quite, but equally as annoying) <ul><li>By implementing coastal management methods, you transfer your problem and multiply it for your neighbours further down the coast. </li></ul><ul><li>Task: With the aid of diagrams, explain how building groynes and breakwaters will cause a problem for others. (Read bottom paragraph – p.68 UG) </li></ul>
