shelters the shore from wave action. This structure has many different designs; it can be used to protect a cliff from wave attack and improve slope stability and it can also dissipate wave energy on sandy coasts. Challenges /Limitations /Disadvantages However‚ a seawall may not protect a coast from erosion in the long run. As waves break against the seawall‚ the curved sea walls reflect the energy of the waves which is redirected downwards‚ to the base of the seawall‚ resulting in a strong backwash

The coastline I have chosen is part of the world heritage site (the Jurassic Coast)‚ from Old Harry Rocks to St Oswald’s Bay Discordant Coast - the structure and alignment of these rocks have a significant effect on the landforms produced. This is a discordant coast where the geological sequence has produced distinctive coastal landforms. At Old Harry/Ballard Point and at Durlston Head are outcrops of rocks resistant to erosion.

The Borth-Ynyslas coastline is an area currently undergoing a major change in the way it is managed. Your task is to find out:

Part 1 The geographical processes that are occurring at the Terrigal beach area are: * Erosion‚ which is effecting: * The Skillion‚ mainly the headland and rock platform‚ which is part of a preserved area of land known as “the Haven” which also contains the rugby oval. The man type of erosion that affects this is from the sea. * The sand dunes on the beaches. This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present. The main type of erosion

also impacting erosion by: the many recreational activities along the beach (e.g. horse riding and four-wheel driving places on large dune areas.)‚ the rising population of Cronulla’s population and the doubled amount of people visiting the Cronulla Coast during the holidays. These factors place pressure upon the infrastructure and coastal environment‚ which can make large dune areas and beaches more exposed to erosion. Are humans impacting water quality at Cronulla?

can feel the sand being washed out from under your feet. The sand being washed out from under your feet as the waves wash over your feet is an example of wave erosion. Waves cause a type of erosion. This type of erosion is most often seen at the coast or along the edges of rivers and waterways. The velocity of waves are affected by slope‚ discharge‚ and shape of the channel of the waterway. Erosion is found on all coastlines in the world. The effect of wave erosion can last up to millions of

When they feed on the vegetation it is called eat-outs which end up making “openings in the marsh vegetation‚ and they are currently affecting an estimated 100‚000 acres of coastal wetlands” (“Nutria‚ Eating Louisianas Coast” 1). Most of the wetlands were “converting to open water at a rate of 25-35 square miles (65-91 square kilometers) each year” (“Nutria‚ Eating Louisianas Coast” 1). At this rate‚ the
