Coastal Management Long Reef Notes Geography Essay

The coastal management strategies are not very effective as gathered from the surveys. On average, the participating surveyees gave the strategies a 4 out of a possible 5. This data were gathered from visitors/neighbourhoods who visit on average frequently. The main concern that would need conventional changes are council clean ups for rubbish track paths, washrooms and toilets, increase and improvement in stores and clubs as well as the immediate removal of pet litter.

This report will discuss the beach of Glenelg on the coast of South Australia. Aspects that will be elaborated on are the history of Glenelg, the location, natural processes that affect Glenelg, human impact at Glenelg, stakeholders in Glenelg, summary of management strategies that have been employed in the past and an evaluation of strategies that could be considered for the future management for Glenelg.

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

* The sand dunes on the beaches. This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present. The main type of erosion, from the sea, takes the sand from the sand dunes as well as the rest of the beach in a rip. The sand is then pulled out to sea where it forms a sand bar. On calmer days, the sand is brought back to the beach.

walkways to prevent human interference. The main reason of dune stabilization is to slow down the speed of erosion. In 1974 the Cronulla beaches were at an all time low and

On the 14th of March 2011, year 10 went to Cronulla Beach to investigate how people use and interact with the coastal environment. We investigated three main things and they were:

Long Island is famous for its sandy ocean beaches. Between the barrier beach and the main coast is the Great South Bay. The beaches and dunes have very different characteristics. The sandy beach is the junction of land and ocean. The sandy beach consists of two zones, the swash zone and the drift line. The swash zone is the area of wet sand, caused by the incoming wave. The drift line is formed by the dead seaweed and other aquatic plants. Behind the sandy beach is the primary dune. The primary dune's main function is to absorb the force of the ocean and protect the great south bay and the island's main coast. In some cases secondary dunes form. These dunes are behind the primary dune and are therefor protected from the ocean. This provides the stability necessary for plant growth. Many time a maritime forests will form on secondary dunes.

These sand dunes are important to the coastline and should be protected from these natural threats. The dunes are important because it is used as a buffer against wave damages caused by storms, cyclones, king tides, etc. which protects the land behind from salt water intrusions. The dunes also act as a sand storage area to replenish and maintain the beach at times of erosion. “Sand suns also provide a foundation for ecosystems made up of a wide variety of coastal life.” (http://curiosity.discovery.com/question/why-dunes-coastal-areas). Due to the sand dunes being swept away by the cyclones and king tides all the protection that the dunes are providing to the inland is slowly decreasing because of the erosion that the cyclones and king tides cause. The erosion effects the foreshore most out of all the parts of the sand dunes. The foreshore is most affected because it is where the waves are most frequently hitting that part of the sand dunes which means that erosion will occur faster there. Due to the foreshore wearing away, sand from the foredune and interdune will replace the sand that has been washed away which means that the establishments that are on the interdune will begin to sink into the

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.

Preserving coastlines is important for the economy and the environment. The fact that the business world and the preservation world are on the same page is a good indicator that maintaining beaches are important for both people and animals. The data that has been collected by both parties, thus far will hopefully bring a more cost effective and more long term solution for beach replenishment. So the beach bums and the sea life may continue to enjoy one of the most beloved landscape for generations to

The Great Barrier Reef is one of the most beloved regions of the world but due to recent human activity in surrounding areas and subsequent sediment delivery, coral and seagrass habits within are being negatively impacted. Extending 2000km along the North-eastern Australian coast (Brodie et al., 2007), the Great Barrier Reef is a major source of income for Northern Australia and fuels the growth of local businesses. As industrialization in areas adjacent to the Great Barrier Reef lagoon have increased since European settlement (McCulloch et al., 2003), the need for more resources to compensate for human population has led to harmful land practices such as overstocking and deforestation for cattle grazing inland. These are causing a significant

The beach has sensitive banks to the conditions of the shoreline and it is possible that the break at North Narrabeen would be at risk. The sea walls risks making the beach too dangerous, particularly the water, but the idea of buying the properties from the owners and creating instead an extended dune system will create a more natural state of the beach, letting natural coastal processes take place

Some amount of natural erosion is necessary to provide the sediment for beaches in estuaries and coastal bays. However, excessive erosion has occurred in the past due to development. Industrial and private development along the world’s coastlines has increased dramatically since the 1970s (Nepf). Developers and builders completed much of this construction without taking into account the effects of coastal erosion. New buildings were often placed too close to the existing shoreline so that

these sand dunes absorb the impact of waves during storms and naturally decrease the speed at that the beach is being eroded.
