Argumentative Essay On Beach Erosion

In the article it states. In the grace of the ocean or the power of the waves some people think when did surfing begin? We know it wasn’t a happy go lucky beach boy from the 80s. Most people believe it was invented by fisherman to get their fish into shore quickly. Later it became a sport of kings the richest people and the kings had up to about 18 to 24 feet long. Instead of calling it surfing the Hawaiians “he e nalu,” or wave sliding. In 1777 Captain James Cook observed canoe surfing in Tahiti and wrote “I can not help concluding that the man had great pleasure!” But do to the Europeans coming to Hawaii they got a lot of diseases and cause most surfing to stop. In 1866 a man named Mark Twain went to Hawaii to rediscover the past and brought

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

Coastal erosion is the wearing away of land and the removal of beach or dune sediments by

Natural disasters are considered harmful in terms of coastal management and can often cause years of work to be wiped out. It can take large amounts of sand from the beach and remove plant life. Collaroy Beach has been a victim of such natural disasters. A large storm back in 1945 caused Collaroy Beach to empty out a large percentage of its sand and damaged many structures. Collaroy Beach’s local council, Warringah Council, has taken action to prevent storm damage in the future. A revetment wall has been established on the sand dunes so waves do not cause as much damage to the dunes behind. Warringah has also purchased properties that were residential and cleared them, so that a storm will not damage as many structures.

It has become common for sand dunes to be bulldozed to improve the views to the sea. However this destroys the natural protection of the coast. Human activities such as water transport also can cause problems for coastal areas. The dredging of navigation channels and the discharging of the material in deep water to enable larger ships to travel though water channels removes sediment from the coastal system leaving the area susceptible to erosion and will also interfere with longshore drift which will prevent the coastal beach landforms from being maintained such as the development of a spit. It is likely that a spit will be eroded and start to regress in conditions such as these.

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

Brighton, Glenelg, The West Beach Boat Ramp, Semaphore and Largs North Beach have all been influenced by hard engineering techniques. As an example, Glenelg was one of the few beaches that had some form of a breakwater along the coast. Breakwaters are notorious for having immediate impacts on the beach, but are ultimately useful in protecting the land that meets the beach. The real question is; “Do the benefits, outweigh the negatives?”. Breakwaters are

participating in annual events to protect and save the sand dunes. The government has also

Beach nourishment is the physical transfer of sand from an area of excess to where it is being eroded. This often involves dredging and transport of sand by truck or through pipeline. Because of the cost involved, beach nourishment is only used where other strategies prove to be ineffective.

Many communities are suffering due to coastal erosion. One example is the village of Cocodrie, LA in Terrebonne Parish. This village’s small population and its 220 residential and commercial buildings are surrounded by marshes. In Cocodrie, there is no barrier against hurricanes. Local marinas play host to recreational and commercial fishing, and The Louisiana Universities Marine Consortium is located in Cocodrie. This facility of around 100,000 square ft houses laboratories, classrooms, and a research center. Infrastructure that will be affected by coastal erosion includes paved highway, dirt roads, a bridge, water supply systems, and natural gas lines. By 2050, Cocodrie will be surrounded by open water as the marshlands around the village give way to rising sea levels. Another community affected by this issue is Yscloskey, LA in St. Bernard Parish. The most important part of the economy here is fishing, and highways link the parish to New Orleans fishing communities. The Yscloskey area lies outside of the protective levees and is quite vulnerable to storms. Though losses in Yscloskey are not predicted to be as great as those in Cocodrie, a 16 percent loss by 2050 leaves the infrastructure of Yscloskey even more vulnerable (Coast 2050, 1998, p. 64-66). Local residents in these areas are watching the land disappear along with the beachfronts and Cyprus swamps that were on that land (Marshall, 2014).

Around the foreshore of both Long Beach and Nutgrove Beach, rocks have been added to the foreshore to prevent further erosion of the beach. This has been successful in reducing the amount of sand that is drawn out to sea.

There are about 15 major sites in the world for big waves surfing that are the most amazing and challenging for a professional surfer. In this article, I chose to present three of them in what I consider the most incredible and life threatening experience.

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

Replenishing of beaches may consist of pumping sand back out onto the beach, or building back up sand dunes. This would result in not enough money to replenish the beach. Only the upper part of the beach would be covered with new sand. This would create a steep beach. Creating the steep beach would increase the rate of erosion. With sand being pumped from the lagoon, or shelf, this

40 years ago Ian Schaeger converted a New York City music hall into the hottest disco in the world and the entertainment industry would never be the same. It was Studio 54 a decadent place where mega celebs like Michael Jackson and Cher would party with writers, street kids and drag queens alongside Wall Street tycoons. It was a place that brought a diverse crowd together who had one thing in common, the love of disco music and the party. 40 years later he has done it again.
