Cronulla And Collaroy Case Study

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.

The Cronulla beach environment features a variety of issues that are both physical and human related; the most prominent issues are erosion, inappropriate development and also pollution. However despite the many issues present at Cronulla, there are a variety of coastal management strategies being administered in order to combat these problems that have a potentiating threat on the beach biome. The predominant strategies used to counter these problems are Seabee walls, Seawalls, and also signage, bins and fences; and these five solutions each have advantages and disadvantages, which ultimately prove whether or not, the strategy itself is successful.

The aim of this report is to investigate Long Reef and Collaroy Beach’s coastal management.

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.

This investigation will be exploring whether the movement of pebbles, shingle, shells and other materials found on the beach have impacted on the shape and structure of Newhaven beach and Castlehead Cliff. One of the key processes this investigation will focus on is that of long shore drift caused by strong prevailing winds, prevailing wind is the direction from which the wind usually blows. Cliffs are made from mainly two materials, chalk which is at the bottom and sand and clay at the top. If cliffs are facing the direction of prevailing wind it may lead in high rates of cliff

The beach is a sand spit that stretches 2.8km long, linking to the sandstone of Sutherland Point at the east. Also the eastern side of the beach is the site on which captain cook first set foot on Australian soil in 1770. The beach is surrounded by various oil refineries and import terminals along with multiple houses that are alongside the road. There are a total of 13 groynes that have been placed in in the 1970’s to stop long shore drifts. At the end of the 13th groyne there is a jetty that stretches out for 1km that has been placed for the oil refinery. During the investigation both primary and secondary sources were discovered of the Silver beach at Kurnell. Focusing on the effects of pollution of the particular area, data was collected on the development and outcomes given from pollution. On the route to the beach there happened to a large industrial site rising many points regarding pollution, which will be discussed further

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

Cronulla is a beachside suburb in southern Sydney, it is located 34.0574° S, 151.1522° E which is 26 kilometres south of the Sydney CBD (see figure 2). It is governed by the Sutherland Shire Council. Cronulla’s coastal environment is on the Kurnell Peninsula, which is made up of a tombolo. A tombolo is a sand spit connecting a rocky outcrop or island to the mainland. So this forms a barrier between Botany Bay and Bate Bay. The two areas of study visited were Wanda Beach and the Greenhills Beach development.

period of time have increased the size of the beach. Enviromental organisations have tried there best to limit the amount of man made deveoplment on coastal lads and many schools

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:

The Port Noarlunga Reef is Adelaide’s main attraction. The reef exists on the eastern side of Gulf St Vincent discovered in 1971 and used for about 36 years. This narrow reef is a sandstone reef as it was formed by sand dunes. The reef is 1.6km long and lying 400m offshore. The reef is separated to two where on one of the sides the species are protected and is a reserve while the other side is where the species are not endangered which includes a mix of heterotrophs and autotrophs. In this part of the reef you can fish or do activities such as boating, snorkelling, Scuba diving, swimming, and recreational fishing. Many focus on snorkelling and Scuba diving, which makes Port Noarlunga reef special and attracts 170,000 visitors per year. The ability to interact with the species and swim and snorkel or scuba dive makes the experience much more natural and fun and hence makes this place Adelaide number one attraction. There is also a underwater trail where this gives education to the youth and also enhances the experience in marine ecosystem.

Barrier beaches are not static, they are constantly being changed (Coastal Change ) by the forces that formed them; waves and wind. One change effecting barrier beaches is they are moving closer to the main coast. This movement is caused by the rise in sea level. As the sea level rises waves crash higher and higher upon the beach, as they do this the dunes are pushed back. There are also seasonal changes in the barrier beaches. During stormy seasons sand is removed from the beach and deposited off shore on the longshore bar. During calm season waves redeposit sand upon the beach and the beach grows.

As one of Devon’s oldest seaside resorts near the mouth of the Teign estuary, Teignmouth is the home to many local residences and local tourism businesses. The shoreline flooding and erosion of Teignmouth has a negative impact on people’s life and the landscape of the resort town. The first sea walls built to protect the town in 1867, which was broken down by the strong sea wave and wind, leading to a terrible flooding of the town in 1908 (Environment Agency, 2015). Later, strong sea waves had toppled down the sea wall, and new sea walls were built again. The year of 1969 had witnessed the breakdown of the sea wall again, which made the Devon River Authority to reconstruct the 145-meter-long sea wall and built 7 groynes to maintain a higher beach level in 1972 (Environment Agency, 2015). In later

Moreton Bay and Tangalooma is the third largest local government in Australia by population. It covers more then 2000 square kilometres and serving nearly 400,000 residents. The council has more then $4.4 billion worth of assets under management. On March 11th 2009, a container ship in the Pacific Ocean lost over 31 containers overboard, it had leaked approximately 270 tonnes of oil 11km off east of Moreton Bay. Their wasn’t many wildlife that was effect from this oil leak. The animals that were effected was treated, cleaned and then released. In Moreton Bay and Tangalooma over 200 turtles are being reported dead, sick or injured. The debris and plastics in the ocean doesn’t just effect the marine life but it also effects human health. Turtles can be very weak due to their downward facing spines, which causes them to swallow their food easy but cannot bring it back up, which paralyses the turtles gut from digesting their food. Most of the pollution that enter the waterways of Tangalooma and Moreton Bay are being flushed into the Bay’s, which is actually impacting the water quality and health of Moreton Bay and Tangalooma. By more and more pollution entering the water ways of the bay’s it can increase the cause the turbidity, nutrients and algal blooms, which can cause the loss of seagrass and a loss of food sources for the turtles and other marine

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
