Brevard's Barrier Island: A Case Study

Barrier Islands are very so hard to protect, therefore, there should be different kinds of information that would help the community distant from these Coast's to commit to preserving a Barrier Island. first of all historically these barrier islands have been hard to protect because the links between them an inshore ecosystems are poorly recognized. some of the ways resolve this issue include putting signs up roads that lead to the coast, putting Billboards up making tissue blown up on a big board, sending mass text out like they do with Amber Alerts, creating symbols or texts on the roads themselves like we have with turn signals, putting more information on local channels for TV, putting Flyers up at local restaurants or bars,

Are these strategies used in the coastline within Randwick city council boundaries and how effective are these management strategies?

Wind and waves affect Glenelg as they set up a northward drift of sand along the coast and this type of sand movement is known as littoral drift. During coastal storms, huge quantities of sand are eroded and this does damage to near shore, beach and sand dune areas. Glenelg is not considered to be a stable as beach as many others are. Seagrass loss and seabed instability that affect Glenelg is that a third of seagrass meadows along the coasts of Glenelg has died since 1950 and poor water quality resulting from the stormwater runoff and effluent disposal has most likely been the initial cause. When there are gaps in the seagrass meadows the sand below the meadow edge can be eroded by the waves and this will in turn increase the rate of seagrass loss and make it difficult for plants to recolonise the seafloor, even though the water quality has been improved. Sea levels affect Glenelg as parts of Glenelg are being subsided as a result of climate change and a relative sea level rise of one to two millimetres per year has been recorded for Glenelg. “As a result of the loss of sand from the seabed, the level of the seabed has steadily become up to one metre deeper and the wave energy reaching our beaches has increased.” (Adelaide’s Living Beaches Strategies,

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.

Collaroy beach is located 16km north of Sydney’s CBD within Warringah Council's local Government Area. It is approximately 3.6 km long from the local Collaroy surf Club to the Narrabeen lagoon in the north. It had extensive development in comparison with other beaches. There are over 120 plots of land and 293 residential units within this area. Many buildings are many stories high to accommodate a large number of wealthy people. This high level of development has posed a serious risk to property due to the effects of erosion, which has shaped Collaroy beach many years along with other natural processes such as deposition. Erosion continues to occur as the land is pushed inwards at a relatively rapid pace. A year 10 grade from Redfield College

North Stradbroke Island (NSI), also known as Minjerribah to its indigenous people, the Quandamooka people, is the second-largest island in the world, covering an area of 275.2 km2. The island has a wide range of ecosystems including open beaches, frontal dunes, rocky headlands, mangroves, and tidal swamps (Stradbrokeisland.com, 2018). On the island, the sand mining company, Sibelco, are to close their operation on NSI in 1919. This decision has been made through the exploration of advantages and disadvantages of undertaking sand mining on NSI, as well as alternative sources of economic income and planning replacement employment. When making the decision to close Sibelco’s sand mining on the island, it was important to remain mindful to the natives of the island and their ideals, traditions and sacred land. In considering all of these factors, it is most ideal for Sibelco’s sand mining operations on NSI to close.

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.

Facing tough budget decisions in advance, various cities, and county have two options: raise taxes or reduce services. Furthermore, there has not been a tax increase in a long period, county officials have alleged. They recognized this day would come. The administrator distressed and diagnosed the circumstances where they provide the primary inspection and repairs.

tides. There are also many programs which help to ensure the stabilization of dunes, these include the planting of new vegetation to combat erosion, fencing and designated

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

Barrier Island is a low edge of sand that is parallel to the mainland with a distance of 2 to 19 miles’ off the shoreline, 300 barrier islands border the shore of Cape Cod, Massachusetts, to Padre Island, Texas. The barrier island defends the coast from the full power of storm waves. In the central of the barrier island and the mainland is a peaceful lagoon or a bay. Mainly most of these barrier island are 0.6-3 miles wide and amid from 9-18 miles long. The highest structures example of barrier island are sand dunes with the height of 16-33 feet; however, in some places the dunes can reach the height of 100 feet. Few barrier islands are initiated as spits that were then detached from the inland by upsurge corrosion, rising of sea level resulting

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

The coastline is also exposed to strong North/North-East winds, which co-enside with a rather generous fetch. Destructive waves are a result, which erode the beaches and attack the foot of the cliffs, removing masses of clay in suspension, resulting in strong marine erosion. The material eroded and transported elsewhere results in little material left to form beaches, which act as a barrier to protect the cliff line from tides, currents and storms, therefore the sea's processed are able to keep cutting back the cliff line.

Coastal dune systems serve as a natural alternative to hard engineering defence methods. They act as a barrier which contribute to the stabilization of the coastal landscape and protects it when coastal disasters occur. During storms, waves flatten the beach and collapse the dune facing the beach, realising sand offshore and creating large bars in the surf zone. These sandbars cause waves to break further offshore, and following the storm, waves with less height return the eroded sand slowly from offshore back to the beach, allowing the dune to recover. In this way, the dunes absorb the impact of storms preventing or minimising intrusion of waters into inland areas, protecting structures from flooding. On the other hand, hard engineering methods tend to interrupt natural beach processes, increasing erosion risk and beach scour, which often ends up in artificial replacement of sand. Therefore, dune systems are highly efficient and the least expensive defence against shoreline erosion, and is a softer solution since there is no introduction of harsh elements to the system (Choi et al., 2013; Gomez-Pina et al., 2002; Cornelis and Gabriels, 2003). An example is the dune system along the Dutch coast, where plenty of research has been done due to their importance as a line of defence feature in the Netherlands (de Groot et al., 2012).
