Gold Coast Beach Erosion

After the dredging in 2009 occurred effects from the procedure were seen within just two weeks, all being negative. Some longterm effects include loss of beaches and marine life. Portsea beach for example is no longer a beach and now the government is spending millions of dollars in sandbags to attempt to stop the beach from degrading even more. Erosion is slowly destroying the coast and

These strategies are sustainable and appropriate however more immediate action should be taken based on visitors’ opinions and beliefs. Coastal management strategies are simply requirement strategies like council clean ups, and does not include necessary updates and improvements in facilities and stores. This beach is lacking in short and long term major improvement plans as it’s an undervalued beach in contrast to more populated beaches. Councils and governments are putting off major plans for a small town beach which is the reason for its slow upgrade time period and lack of serious management.

Seawalls are also strategies that Cronulla and Collaroy implement on their beaches. However, the seawalls in Collaroy are buried under the sand and are only visible after large-scale erosion events. Whereas Cronulla beach’s seawalls are visible and reduce the scenic

Sand dunes are a valid indication of the quality of the soil and the surrounding ocean. When vegetation is established in sand dunes, it stabilises it- i.e. gives the dunes structure. This structure helps prevent erosion by using the plant life to trap the sand. Without these plants (and ultimately the sand dunes) sand will be subject to many natural forces without protection, meaning any major storm could theoretically remove large amounts of sand from the beach with no natural means of replenishing it. Long Reef Beach is commendable in the amount of vegetation it has produced.

This is not just an architectural design and the fashion, but because of the fact that the developers know that the land is being swallowed by the sea. More and more houses, hotels, shops and restaurants have decks and some piers that lead into and over the water. The Florida Department of Environmental Protection even has courses for those in construction to acknowledge the erosion and increase the proper design, construction and maintenance of erosion and sediment control. The beaches, whether sandy or rocky are the buffers that keep the sea at bay from the land behind enemy lines. They are nature’s way of saving all the people and their livelihoods from being swept away into the deep blue yonder. When waves crash into the beach it carries sediment with it and deposits such sediment. The alternative is that when a wave recedes back into the ocean it carries that sediment back to sea. This is usually done at an unequal rate, and leads to coastal erosion. In fact, coastal erosion is one of the reasons we have so many beautiful beaches around the world due to their unique shape. Long shore currents move water in a parallel direction of the shoreline, carrying the sand with it. But as we continue to build piers, docks, sea walls, and jetties

There are 2 types of beaches. One is erosion dominant and the other is deposition

The Year 10 geography field trip was an insightful experience into the workings and functioning of metropolitan coastlines here in South Australia. The day consisted of visiting various beaches in Adelaide that were influenced by some form of hard or soft engineering techniques that changed the natural processes of the beaches. What was evident from this trip was how much these beaches have been changed to an extent where it is unlikely that they will ever go back to the way they were prior to human settlement.

At Nudgee Beach, erosion was found to have occurred on the edges of the mangrove forest and along the mudflat shorelines. Erosion is typically influenced by natural factors and occurs when pieces of weathered rock or soil are moved – typically by wind and water – from one place to another. Shorelines with lots of sediment and sand are more inclined to be effected by erosional progression. Erosion may also be provoked and accelerated by human interference. For example, if the decision to clear trees and plants from an area is made, erosion is likely to occur as the root systems of plants work to hold the soil in place. If these root systems are removed and erosion does occur, environmental conditions – such as; landslides and flooding – are more likely to take place. Erosion may also cause other plants to tip over, have their underground roots exposed and damaged and contribute to the pollution of local waters; as a result of mud and soil runoff [26]. Erosion at Nudgee Beach was likely to have been influenced by natural factors; however, the development and extension of the Kedron Brook golfing course may contribute to the acceleration of erosional processes and further damage the mangrove

The more coastal erosion there is, the higher the chance is for saltwater contaminating freshwater resources and the salt from the ocean can cause soil to be uninhabitable to plants (Again this can affect agriculture). Coastal erosion is not only an issue for water resources, it’s also a direct issue for the communities. The communities on islands lay very close to the coast and important infrastructures are one of them. Islands cannot get all of their resources from the local farmers, so they import it via plane or boat. The problem with that is the airports and ports are all on the coast. Coastal erosion has the power to ruin airport runways and docks of the harbors and ports; this means that eventually communities will be starved of basic necessities and there will be no way of getting in basic needs. Not only will airports be ruined, so will our tourism industry. Coastal erosion will eventually ruin the beaches that attract tourists. Island communities depend on the tourism industry because that industry brings in a lot of money every year. Without tourists, communities will struggle financially. Lastly, the ecosystem of the islands will suffer the

Erosion is unfortuanately present at Cronulla beach, the local government have tried to tackle this problem with solution such as dune stabilization and rip rap

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

Erosion is mainly caused by two main natural forces: water and wind. In Southwest Louisiana, erosion by water is one of the main issues we have as a coastal state. There are different factors that must be considered when looking at water erosion

I found out a couple things about coastal erosion. One is that it affects everyone who lives on a coast directly

Furthermore, extraction of building materials such as sand affects coral reefs, mangroves, and hinterland forests, leading to erosion and destruction of habitats. Overbuilding and extensive paving of shorelines can result in destruction of habitats and disruption of land-sea connections such as sea-turtle nesting spots. Coral reefs are especially fragile marine ecosystems and are suffering worldwide from reef-based tourism developments. Evidence suggests a variety of impacts to coastline ecosystems result from shoreline development, increased sediments in the water, trampling by tourists and divers, ship groundings, pollution from sewage, overfishing, and fishing with poisons and explosives that destroy coral

The erosion of shorelines is a natural process that can have beneficial or adverse impacts on the creation and maintenance of habitats. Sands and gravels eroded from the shores of coastal bays maintain the beach as a natural barrier between the open water and coastal wetlands. Beaches move back and forth onshore, offshore and along shore with changing wave conditions. The finer-grained silts and clays derived from the erosion of shorelines are sorted and carried as far as the waters of wetlands or tidal flats, where benefits are derived from addition of the new material. However, excessively high sediment loads can smother submerged aquatic vegetation beds, cover shellfish beds and tidal flats, fill in riffle
