Coastal Erosion In Australia
Collaroy-Narrabeen beach is a beach located on Sydney’s coast and is managed by the Warringah council and is Sydney’s 2nd longest beach at 3.6km. The beach is the most vulnerable beach to erosion from coastal zones in Warringah and comes in at 3rd place in being the most at risk area from coastal processes in Australia. Warringah council however has put in a range of measures to lessen coastal
Ecological Succession Report of Conrad’s Beach Anthony Cormier (B00719104), SCIE 1505X October 23rd 2015 Abstract – The study to prove that ecological succession occurred at Conrad’s beach took place at Conrad’s beach in Nova Scotia. Species richness, height and amount of organic material was sampled by using a 1m x 1m quadrat. As predicted the abundance and size of the organisms were larger further as the groups got further from the sand dunes.
Barrier beaches will only occur when there is enough sand for the beach to form, sea levels are rising, and there is sufficient energy from waves and wind to move the sand2. Since these beaches are made wholly of sand, they are constantly being moved by the waves and wind by which they were formed. Barrier beaches such as Monomoy promote the development of marsh and wetland habitats, by protecting the area from harsh wind and waves. Monomoy Island is an important aspect of the cape cod coast. Located at the southern tip of the outer cape, it provides a home for countless seals and other wild life.
Firstly, sea-level rise is an environmental issue that’s been detrimentally affecting coastal cities for decades. For example, the capital city of Thailand, Bangkok is one of the world’s most vulnerable regions
Investigate the economic, social and environmental implications of changing land use around Sydney Harbour. As one of the most recognised icons in the world, Sydney Harbour has been fundamental to the history and the development of both Sydney and Australia as a whole. Although still the same size and location, there have been many changes in the use of the land in Sydney Harbour over the past thousands of years , in particular the Millers Point and Barangaroo precincts which lie among the southern side of the harbour. Through this change in land use, economic, social and environmental implications of the harbour have created many challenges for the government and community.
Despite the prevention efforts, the Outer Banks is still suffering from erosion due to its building permits. Building, repairing, remodeling, or destroying structures causes an increase in beach erosion by shifting sand making it easier to be eroded by wind, rain, and waves. When building properties, the company must measure the oceanfront setback, the calculation of the average shoreline change rates for the next fifty years (“State of the Beach/State Reports/NC/Erosion Response”). This should allow for the company to not have to make any changes to the building for at minimum fifty years. However, due to the machinery used to complete construction the sand erodes more, causing the shoreline to move inland sooner.
Recently, because of the downturn of sharks, those coral reefs and seagrass
The ways of minimizing the damage done to the cemetery are adapting to the effect by attempting to slowdown the rate at which the seas are rising through living shorelines like geotextile bags and oyster shoreline. The living shorelines are short-term like most mechanisms against sea level rise, but are more eco- friendly then the alternative attempt at defense mechanisms. Examples of defenses against sea level rise are armored shorelines as presented at many St. Augustine sites currently as large amounts of concrete or rocks. The most long-term and effective use of energy is retreating, accepting the unavoidable rise of sea level and actively preserving assets accordingly. Ultimately, global warming and sea level rise are inevitable.
On the Beach by Nevil Shute is an apocalyptic novel written in the mid-1950s. The non-fictional account tells the story of multiple people in Australia, and their life after nuclear war. The characters all cope with their approaching demise from radiation, and the story successfully shows the differences in each person’s handling of the situation. The Northern Hemisphere of the Earth has been destroyed by nuclear war and the only surviving people are those living in southern Australia.
A resident at the Outer Banks that is the owner of the Cape Hatteras Motel in Buxton, on Hatteras Island has said that “Over the years, she has watched the ocean eat closer to her buildings” she also said “our property line is about where that wave is cresting" as she said this she was gesturing toward a point about 500 feet out in the water (Rising Seas: Will the Outer Banks
This case study includes a description, about Holderness and issues relating coastal erosion and methods which can be used for solution to reduce the amount of land eroded . Holderness is located in an area of the East Riding of yorkshire, on the east coast of England. Holderness contains many cities which are flamborough Head, Mappleton , Aldbrough, withernsea
Many people lose their livelihood, for e.g. farmers. These people will need to be compensated, which is usually costly. The cost depends on amount of compensation to be paid to the local people affected by erosion. Land Management Maintenance of sand dunes provide a natural defence against the sea.
The history of scarification is an ancient tradition of cutting the skin in a specific way and manipulating the cut to form a scar, usually attempting to form a keloid scar, which is when the scar is raised. It is unclear as to when scarification originated, but it is generally thought to be as old as tattooing, which potentially dates back over 10,000years. Scarification is most prevalent in Indigenous Africans and Australians, as tattoos would not show as clearly on darker skin, and instead led to scarification being the main form of body modification. Most scarification result within individual tribes and families, and therefore it is important to note that scarification differs greatly around the world, and no two tribes are the same, and even scarring within a singular tribe can differ from person to person. For that matter,
When large storms hit land with these increased sea levels it causes large storm surges that can destroy anything in its paths. If temperatures continue to rise other natural disasters could occur ("Global Warming Will Produce More Katrina-Like Storms"). A warmer wetter atmosphere could spawn more tropical storms and there will be floods in places that do not get much rainfall. Humans could prevent these problems if they were to cut down on the use of fossil fuels and use more renewable energy. Renewable energy consists of wind, solar, and lunar power.
Running water is one of the most effective agents of erosion. This is because no matter how big or small the rock that falls in the moving water is, the water will always be able to at least pus it forward if not able to keep it floating. This often causes rocks to scrape against each other and then the smaller particles that can float and go to the side of the river, are deposited ashore. The power of oceanic waves causes it to erode coastline rocks. The erosion of wind is most powerful in desert due to the small sand particles that are easily moved by wind and have a strong effect on weathering rocks.
