Coastal erosion is a diverse issue with many different causes. However, it is basically defined as a situation that for some reason or another causes the amount of coastline in a given area to decrease. The causes behind coastal erosion are varied. They are often the result of manmade problems, such as pollution (Williams). However, the erosion of some coastlines is a natural process that occurs without human interaction (Internet Geography).
Just as important as understanding the definition of coastal erosion, is appreciating where the phenomenon it is happening. It is important to recognize that coastal erosion does not affect every beach and coastal area in the world. In fact, there are many areas of the world’s coasts that are actually growing from sediment deposits. Whether a particular costal area is growing or eroding is the result of complex natural (and sometime unnatural) process (Williams). Furthermore, the ability of scientists to find out exactly if a coast is eroding (and if it is, by how much) is critical for science to better understand the issue of coastal erosion. Scientists are able to look at geological data and take specific measurements of coastlines at different times of day and at different tida...

- Term Project: Coastal Erosion A house begins to slowly crumble, slipping its way off the cliff. For years, waves had battered at the rocks, stripping and eroding away the land over time. Coastal erosion has been a pressing issue throughout the ages and today it is more prominent than ever. Recently, Europe experienced some of its worst storms and flooding in decades, leading to an estimated one thousand percent increase in coastal erosion (“Coastline Erosion Dramatically Accelerated by Winter Storms”)....

- Erosion is when the elements such as wind, water, and ice remove pieces of land. (“What is Coastal Erosion?”) Coastal Erosion takes place when destructive waves wear parts of the coast away. Four ways in which this takes place are corrasion/abrasion, hydraulic action, attrition, and corrosion/solution. (“Internet Geography”) Corrasion/abrasion is when materials are hurled at the base of cliffs through waves. Hydraulic action is when waves hit the base of a cliff and air is compacted, when the wave leaves air is rushed out and often this causes the material to break.... [tags: Ecology ]

- The Environmental Tragedy of Coastal Erosion A very high percentage of the American population resides at or near one of the coasts. Preserving beaches is a very costly endeavor and there have been many debates over which way this country should go about doing so. On the east coast the current strategy is, “beach nourishment programs”, whereby sand is taken from available sources and put back onto the eroded beach (Michaels, 01). In 1999 the United States government spent about $150 million on beach nourishment programs, state and local governments along with those who own their own beach property spend even more on such projects (Michaels, 01)....

- Coastal Erosion At Dunwich This question is asking for the reasons as to why the coastal erosion at Dunwich takes place. I have already shown that there is coastal erosion in question one, and now I am going to explain why this erosion happens. To show how the erosion takes place, I will look at many different factors: wave type, long shore drift, the geology in the area, and beach profile. Natural Erosion Fig 2.2 on page 3 shows the sand martins nests, which are a contributing factor to the erosion of Dunwich Cliffs.... [tags: Papers]

- Coastal Erosion With Reference to examples discuss the view that coastal erosion is caused by human intervention as a posed to natural processes. For many decades the approach to rapid coastal erosion was to build up sea defenses, to try and slow down or even stop the erosion. Initially the attempts were thought a success, however after some years it was realized that the power of the sea and waves could overcome human attempts. Only could protection be a success if huge costs were going to be involved.... [tags: science]

- Coastal Erosion [IMAGE][IMAGE]Coastal erosion presents a problem along the coastlines of Britain. One of the many areas affected by this is Walton-on-the-Naze, situated in the Southeast coast of England, about sixty-five miles from London. Walton-on-the-Naze is a dated tourist resort with a pier, which has an end shut off due to unsafe structure. There is an area of cliffs further up coast, which are suffering from erosion and cliff collapse. The government has erected a number of different sea defence mechanisms including groynes, rip rap and wooden revetments.... [tags: Papers]

- Coastal Erosion Problems in Walton on the Naze The reason for doing this piece of coursework is to investigate the coastal erosion problems in Walton on the Naze. In this project I will be answering one main question: What should be done about the erosion of the Naze. Walton on the Naze is a seaside resort along the coast of Essex just 8 miles south of Harwich, it is the most easterly part of the Essex coastline and it is surrounded by the North Sea. Walton is situated in southeast England and in north Essex, near Clacton (11km direct), Colchester (27km direct), and Brightlingsea (19km direct).... [tags: Papers]

- Investigation on Coastal Erosion In Porlock Bay Aims ---- Aim 1: To find out if beach material is moved across Porlock Bay by longshore drift. Aim 2: To find out which type of sea defense is best for Porlock bay. If L.S.D. (long shore drift) were taking place I would expect to find: a) Deposition at one end of the bay and against any abstractions such as groynes. b) An increase in pebble roundness in the direction of long shore drift. The process of attrition will erode the pebbles.... [tags: Papers]

- Coastal Erosion and Defence in White Cliffs Country Introduction The shoreline is a dynamic system where stability is maintained despite the continued movement of waves, tides, wind and sediment.The present configuration of the shoreline is now controlled by the various coastal defences', which mankind has put in place over the last 100 - 200 years. These have stopped or slowed the transport of sediments and reduced the ability of the shoreline to respond to Natural forcing factors.... [tags: Free Essays]

- The Success of Management Policies in Dealing with Coastal Erosion and Flooding Roughly a quarter of the English coastline has been developed for housing, industry or leisure purposes. At these sites coastal management has been introduced to protect the coast from flooding and coastal erosion. The particular area of coastline I studied in detail is on the South-East coastline of England and includes various sites along it. These include Camber sands, Dungeness and St Mary’s bay....
