Coastal Erosion Coastal Erosion is a huge problem today and is causing our beaches to get smaller and smaller every year. Coastal erosion is also causing the coast lines to recede and therefore taking away space for which people build on. Even though coastal erosion causes issues it is also the effect of something‚ Humans! Nature has a way of keeping the world in balance‚ it creates things such as barrier islands and sand dunes to help protect against costal erosion. However‚ humans play a

Case Study: Coastal Erosion: Holderness Location | * Holderness is an area of the East Riding of Yorkshire‚ on the east coast of England. * Sub-cell that stretches from Flanborough Head to Spurn Head. | Erosion | * Fastest eroding coastline in the UK. * Rapidly retreating coastline. * At Flanborough Head‚ the average erosion is greater than 10cm a year. * By Mappleton‚ the average erosion is greater than 200cm a year. * At Spurn Head‚ 500000 tonnes of sand is moved by the sea

Processes Operate at Coastal Geographic Environment. Natural Processes are actions or events that have natural causes‚ which result in natural events. The three main coastal environment processes that operate at Muriwai are Coastal Erosion‚ Coastal Transportation and Coastal Deposition. The elements that interact to produce natural processes are wind‚ waves and tides. Each phenomenon at Muriwai’s coastal geographic environment has been produced by interaction. Coastal Erosion is a process

Coastal management is managing development along the coast in a sustainable way so that it will not be spoiled for future generations and it is a very important to Australians because over 85% of our current population live within 50km of the coast. Furthermore‚ more than 25% of Australia’s current population lives within three kilometres of the coast. All the human traffic our coastline receives damages the delicate ecosystems that are trying to co-inhabit the area. Foreshore developments such as

When standing on the sand on the beach you 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

Coastal Processes Coasts are shaped by the sea and the action of waves. Waves act in different ways‚ through the processes of erosion‚ transportation and deposition. Coasts: A coast is found where the land meets the sea. Coasts undergo change due to coastal processes and (as with rivers) there are main processes at work: Erosion Transportation Deposition Each of these processes involves the power of the sea and the effect of waves that are carried to shore. However other factors also

Describe and explain the concept of a sediment cell and how it can be used in coastal management A sediment cell is a length of coastline in which interruptions to the movement of sand or shingle along the beaches or near shore sea bed do not significantly affect beaches in the adjacent lengths of coastline. In addition to this‚ it can also be referred to a sediment that is moved along the coast by long shore drift appears to form part of a circular cell which leads to it eventually returning up

1 kilometre stretch of seawall. Advantages A seawall provides excellent defence where wave energy is high‚ reassures the public and has a long life span. It protects the base of cliffs‚ land and buildings against erosion. and can prevent coastal flooding in some areas. Breakwaters How it is designed to overcome the problem An offshore breakwater is a structure that parallels the shore (in the nearshore zone) and serves as a wave absorber. It reduces wave energy in its lee and creates a salient

this is the most important process forming this feature. The Muriwai coastal environment is a unique environment where the coastline and relief is constantly being shaped into landforms such as caves‚ arches‚ stacks and stumps through marine erosional processes and wave refraction. The combination of these processes working in conjunction with each other in the vanity of the Otakamiro point headland in the Muriwai coastal environment‚ consequently resulting in the current headland morphology of

Coastal erosion at Happisburgh‚ Norfolk Happisburgh‚ on Norfolk’s North Sea coast‚ is a village with a population of 1400 people in about 600 houses. The village contains a notable stone church dating from the 14th century‚ an impressive manor house‚ listed buildings and a famous red and white striped lighthouse (Figure 1). Although now a coastal village‚ Happisburgh was once some distance from the sea‚ parted from the coast by the parish of Whimpwell‚ long since eroded away. Historic records indicate
