mplication because as sea levels being to rise, sections of land which were not exposed to the sea are now in direct contact and begin to undergo the process of beach erosion. The tides become more powerful and more and more sediment is washed out to sea. Global warming has also been connected to the development of more irregular weather patterns such as stronger hurricanes and greater instances of flooding. These two extreme weather conditions heavily affect coastal environments due to the fact that they are right at sea level.
C. Changes due to Prevention
There are several preventative measures which have been used in efforts to stem beach erosion. These include but are not limited to, beach replenishment, seawalls, revetments, jetties, etc. These methods of protection and prevention will be discussed later in the paper but the important thing to note is that none of them stop erosion completely. As of now there is no way to completely

When erosion occurs the beach that comes out of it is never the same. When there is gradual erosion it is harder to see the changes that our occurring and it is only till a major storm or flooding do we usually notice what happens when massive erosion takes place.
A. The Natural Environment
The beach is an ecosystem within itself. A typical coastal ecosystem may be inhabited by birds, grasses, shellfish, fish, invertebrates, and other things. These ecosystems are already combatting the threat of human development and activity in their environments. This coupled with the fact that the beaches are receding due to coastal erosion, ends up being disastrous for many coastal ecosystems. Erosion has caused species to die out in some beach environments because the changes to the environment has made the landscape uninhabitable for certain creatures.
B. How Humans are
However, if any action is taken to defend the coastline, if you hinder in nature's course of beach erosion, there will always be after effects resulting from unnatural intrusion. This proves that any sea defence could prove a problem especially with the land owned by Nation Trust. Nevertheless if you could prove to the owners of the land to the extent of which erosion is taken place and show them how much LSD is affecting the area, action may well become a better option.
There are many things working together to ensure Dune stabilization. These include; re-vegetation, fences, poly-mesh fencing, planked walkways, and controlled pedestrian access. This method is a softer option than the rip-rap wall and is used because human land-use, which at this place consists mainly of recreational buildings, is far away from the ocean. Deposition is also being managed at North Cronulla beach. Dune stabilization is being used to prevent deposited material from being eroded away.
There are many different types of coasts that exist throughout the United States. The south shore of Long Island has a unique types of coast known as a barrier beach. Barrier beaches are long narrow land forms that are composed of sand and other lose sediments. These sediments are brought together by the actions of waves, currents and storm surges. Barrier beaches are subject to constant changes by the same forces. Sand is constantly eroded in one area an deposited in another. Barrier coasts are important for a number of reasons; they protect the mainland of Long Island from the open ocean and flooding during storms, for recreational use and the unique ecosystems which exist on barrier beaches.
Longshore drift is a process by which sediments are transported from one place to another. When this process occurs, beaches, spits and sandbars are accreted over time. If the process of longshore drift is altered by factors such as stronger winds and stronger currents, beach erosion begins at a faster rate and this may result in many serious problems. The main stakeholders of longshore drift are resort owners. They rely on people to visit their resorts and enjoy the beach. However, if longshore drift erodes too much sand, it can permanently deprive sand from the area, which can also threaten structures close to the shoreline.
The hypothesis presented in a paper titled, “Barrier Island Formation”(Hoyt 1130), is as follows: Along a sand shoreline, wind will form dunes or ridges (depending on the type of material the beach is composed of). If there is a relative submergence, the area landward of the dune/ridge will be flooded to form a lagoon and the ridge/dune then becomes a barrier island. This would most likely occur when a stable shoreline with a well-developed ridge is engulfed by a relatively sudden transgression that does not erode or push the ridge landward (Ot...
There has been a legislation put in place to protect coastlines. According to Kathryn Free, The South Carolina Coastal Zone Management Act of 1977 was passed by the General Assembly to make available protection and improvement of the state’s coastal resources. The Act has an extensive range of purposes to inspire coastal management and protection of natural coastal resources. The Act also created the South Carolina Coastal Council and gave it direct regulatory authority over “critical areas” of the coastal zone, including coastal waters, tidelands, beaches, and primary oceanfront sand dunes (Free 15 -16). However, it was soon obvious that the Council could not achieve these legislative goals because they lacked authority to thwart construction near eroding shorelines.
Ecosystems rely on the interactions between the four spheres of the biophysical environment, the lithosphere, hydrosphere, biosphere and atmosphere for its unique character and functioning. These biophysical interactions and their processes have significant dictated the coastal sand dunes. Coastal sand dunes are large accumulations of sand located immediately behind the active beach zone. They are found on all the world 's continental land masses. This is evident in the effects of the atmposhere and hydrosphere as well as with geomorphic and biogeochemical processes, have on the dunes. Therefore, the variety of factors arising from the interactions between the spheres has lead to diverse ecosystems and their functioning.
If nothing is done to preserve the beach and allow the continuation of beach recession, it will result in the loss of the beach culture and recreation, loss of revenue from tourism and local visitors and loss of property value for the residents.
The coast is dynamic, meaning it is constantly changing. It does so as a result of erosion and deposition, forming various types of landforms in the process. The landforms of erosion are headlands, bays, cliffs, rock platforms, caves, arches, stacks and blowholes. The landforms of deposition are beaches, lagoons, bars, barriers, spits and tombolos.
The beach, as mentioned in the introduction, has some coastal and environmental issues. These issues include erosion, removal of vegetation and pollution. Although it may not seem like there are many issues these issues are big. On top of these issues there are social, economic and environmental issues as well.
First of all, as the water temperatures rise, coral bleaching becomes possible and when it becomes too hot, algae is released from the corals, making them fully white. Another consequence of global warming is an increase in droughts. When the temperature is increased for a period of time, the amount of water decreases as wind pressures do the opposite, causing droughts all over the world. Furthermore, when water vapor condenses due to the heat, the surrounding air warms as well, causing hurricanes. As the temperature rises so does the length and strength of the hurricanes. Sea level rising is a consequence that is caused by warmer oceans and the melting of land covered in ice, both primarily caused by global warming. The ocean and atmosphere work side by side and if one’s temperature rises so does the other’s. The ocean temperature continues to rise and the amount of water vapor in oceans increase too as a consequence of global warming. Last but not least, ocean acidification, is the final consequence of global warming in this list. As carbon dioxide levels rise in the atmosphere, pH levels reduce in the ocean, causing ocean acidification and death of fish along with
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. Many methods around the British Isles have taken place in he last 50 years with many failures occurring. It is very rare to find a coastline that shows a decrease in the rate of erosion over many years after defenses are in place. In fact in places the defenses seem to have speeded up the erosion process. Coastal erosion is a natural process of erosion, transportation and deposition, interfering with this balance could be to blame for the rise in erosion on the coasts of some areas.
The ocean, beautiful from what everyone can see, but there’s more to what the tourists’ eyes show as they come to see the views on the beaches. Coral reefs are starting to deteriorate more severally due to human and natural causes. The tourists visiting these beaches have no idea that they are affecting how long the coral reefs are going to last and how fast they are going to be gone. If nothing is done to help the reefs they may be gone sooner than later. Many people believe that the reefs are dying off because all because of natural causes and the human activity is helplessly getting the blame. Although natural causes contribute to the decrease in reefs, human activity is the main cause in way the reefs are not able to live as well as they
There are two different forms of a water erosion, soil movement and bank erosion. First soil movement is a sheet erosion, which is mass wasting, movement, and slope movement. Second form of water erosion is bank erosions. This is the wearing away of the banks of a stream or river. Some effects of the water erosion is due to the climate and the soil surface. Depending on the weather such as the wind, rain, snow, or if it’s sunny it can affect the erosion process. The soil surface effects the erosion because this is where cropping is done.
The problem with contaminated beaches will soon take effect on everyone. The main causes that pollution creates in the beaches are from heavy rainfall, natural disasters, and plant malfunctions. Government agencies cannot control the weather, but they can control what goes into the water. In the United States, the number one reason why beaches are closed down are due to contamination in the water that may be harmful and are left untreated. The arising problem with the beach is that the industries are producing toxic chemicals and tossing the unwanted waste into the ocean. Also, the public are recklessly throwing their trash out into the streets. A prime example to demonstrate this is, if someone was trying to throw a bottle into a street trashcan but missed, he/she is unlikely to pick up after himself/herself if no one was around to see it. This scenario causes pollution to the sidewalks. When mother nature disasters occur, these waste products will end up in the storm drains and into the sewage system. The overflow of debri from the cities can flow into the rivers and if not preserved, it can flow into the ocean. The rivers will then carry these human caused waste into t...
