Semaphore is a classic Adelaide beach supporting many facilities. However, this would not be the case if coastal management was not put into progress. Coastal management is a way of supporting the world’s coasts, by using many techniques from construction of structures in which prevents wave energy from reaching the shore to planned strategies. Factors of this includes; rising sea levels, erosion, long and short term drift, sand movement and marine biology. The importance of coastal management is quite significant as it will help to prevent coastal erosion. In addition to this, without coastal management the world will be affect economically, environmentally as well as socially. Without the strategies involving the management of the coast, …show more content…
Semaphore Beach is affected by many factors such as natural processes and human impacts including marine litter and the discharge of stormwater. Therefore, several plans have been employed to ensure that the coast is supported through the method of counteracting erosion. However in the future, many management strategies have been put into consideration as well as the environmental, economic and social impacts as well as the predicted consequences. These impacts include traffic related incidents, noises and air pollution and the disruption of wildlife and the erosion of dunes. A method that should be considered for future management of the beach is the use of a concave sea wall, although efficient, this structure would be quite costly. Without the use of coastal management, Semaphore Beach would be unsupported, therefore negatively being affected by a variety of …show more content…

However, the fact is, and statistics prove that over 100 million sharks are killed every year (according to the Sea Shepherd website), all around the world and for what reason? Shark culling and the hunting of sharks as a solution to beach safety has not been well received by the Australian public. Whilst it is very clear that we need a solution to protect our bathers and surfers, the Herald Sun reported that 82 percent of all respondents to their
Investigation on Coastal Erosion In Porlock Bay Aims ---- Aim 1: To find out if beach material is moved across Porlock Bay by longshore drift. Aim 2: To find out which type of sea defense is best for Porlock bay. If L.S.D. (long shore drift) were taking place I would expect to find: a) Deposition at one end of the bay and against any abstractions such as groynes. b)
It is being managed by the local council in two different ways. These include; a rip-rap wall, dune stabilization. The rip-rap wall consists of large rocks which have been piled up at an angle. Behind the rip-rap wall the land use is mainly commercial, but there is also some residential land-use. This method has been used because human land-use is right on top of the ocean, and in order to defend these buildings a hard option is required.
Longshore drift is a process by which sediments are transported from one place to another. When this process occurs, beaches, spits and sandbars are accreted over time. If the process of longshore drift is altered by factors such as stronger winds and stronger currents, beach erosion begins at a faster rate and this may result in many serious problems. The main stakeholders of longshore drift are resort owners. They rely on people to visit their resorts and enjoy the beach. However, if longshore drift erodes t...
The damage of the Sydney June storms was devastating. Though such a powerful storm could not have been prevented, measures could have been taken to improve and minimise the impact and destruction of the storm cell. There are a number of ways in which citizens of coastal environments and suburbs could promote the sustainability of their area and the safety of their homes. Apart from the local council, coastal environments and suburbs would benefit from establishing groups of concerned residents to solely promote sustainability and prepare for damage. This group will help monitor erosion, ensure laws and rules are followed by residents and visitors and suggest ways in which coastal environments can be improved. Sufficient signage around
Surfers, swimmers and sunbathers use beaches for recreation. People fish off beaches for food. Since many people take their vacations at the beach, lots of beaches in tropical locations are important to their country’s economy. Entire cities, regions and countries depend on the money tourists spend while visiting the beach. Beaches are naturally very dynamic places, but people try to control them and build permanent structures, such as houses, restaurants, shops and hotels, on or near the shore. The natural erosion and deposition of beaches becomes a problem. Beaches con disappear over time, or even over night during severe storms. Beaches are areas of loose sediment (sand, gravel, cobbles) controlled by ocean processes. Most beaches have several characteristic features. First are offshore bars, which help protect beaches from erosion. Next is the foreshore, which rises from the water toward the crest of the next feature; a berm. On low-lying shores, dunes form behind beaches. Dunes look like rolling hills of sand and are blown into place by the wind. New, smaller dunes are often changing shape as the wind continues to affect them. Waves and currents move the accumulated sediment constantly creating, eroding and changing the coastlines.
Overall the reef receives runoff from at least 35 major catchments that drain 424,000 km2 of coastal Queensland and the amount of sediment flowing into the marine park has just about quadrupled over the past 150 years. There are significant effects from these run offs on the reef, especially the inshore areas close to the developed coasts, effects such as mangroves dying-back and increased amounts of overbearing algae on coral reefs. Good water quality is the reason why the Great Barrier Reef is one of the most beautiful, diverse and complex ecosystems in the world and the decline in water quality can affect all the corals, seagrass and other important habitats as well as the marine life supported by those habitats. The decline in water quality would be detrimental to the tourism and fishing industries. As of right now the “Reef Water Quality Protection Plan”is in place. This plan aims to halt and reverse the decline in the quality of water flowing into the Great Barrier
The North Carolina coast is a large part of the economy and brings countless people joy each year. Unfortunately, coastal environments are constantly being reshaped by tides and waves by moving and depositing sediment. This reshaping of the coast causes houses and bridges to be undermined as longshore currents move sand away from certain areas to others. Also, channels for boats migrate and fill with sand making industry and travel challenging. Despite efforts to stabilize areas, waves constantly batter the shore erasing all attempts. Due to all the social and economical effects coastal environments have on the state of North Carolina, it is essential to find an effective method to stabilize these areas while reducing the cost.
Did you know there are 10,685 beaches in Australia? Beaches like Bondi are Aussie icons and magnets for tourists, it's a playground for most but a disaster zone for others. For many people such as me and maybe even you, these beaches brimming with beautiful sea life, golden sand and a broad stretch of turquoise water spread along the coastline are a jewel. However to others they are filled with dangerous rips, deadly animals, prominent rocks and glaring rays of sun that could danger lives of those beachgoers. Even from time to time every swimmer has had the niggling thought of the possibility of being caught in a rip, dragged away from shore, drowning or attacked by a shark.
The Great Barrier Reef Management Authority identified in an outlook plan for the reef that climate change is the long term threat that will destroy the reef. The Australian Government and Queensland officials have formally agreed to undertake an assessment on the Great Barrier Reef and the routes taken in order to maintain the reef’s beauty. A public group has been set up, allowing for people to have their say in how to protect the reef. There is a Long-Term Sustainability Plan for the Great Barrier Reef being undertaken by Australian and Queensland officials. This plan involves both costal officials and those of the general public that want to get involved. Officials have taken in all the comments from the general public and are expected to come up with a shot and long term plan into order to sustain the Great Barrier Reef.
The world’s largest living organism, the Great Barrier Reef, could be on the verge of dying from various reasons, but there are ways people can help preserve it. The reef is dying because of careless human behavior, causing coral bleaching, over fishing, and diminishing water quality. It benefits people by the food, income, and medicine it provides. People can help preserve it when on the reef, fishing and boating, and at-home lifestyles. People are responsible for a large part of the reef’s death and are also responsible for the preserving of it.
Australia has more than 30 years of expeirnce of evaluating PPPs (policies, plans and programs) under different legislative mechanisms. In May 1992 the Australian Commonwealth, all States (6) and Territories (2) and Australian Local Government Association, signed the Intergovernmental Agreement on the Environment (IGAE). The signatories agreed that ‘environmental issues associated with a proposed project, program or policy will be taken into consideration in the decision making process’. Clearly, the IGAE enveloped the principle of SEA (Kelly et al. 2012). Following this after an extensive review of Environment Protection (Impact of Proposal) Act 1974, in 1999 Environmental Protection and Biodiversity Conservation (EPBC) Act came into force. This Act formally introduced SEA in Australian legislative context. Before this SEA was informally applied to propsals nationally and regionally but no mandatory or formal bindings (Marsden 2013b). Section 146 of EPBC Act introduced the discretionary provison of SEA in all sectors excepts for fishery which has been made mandatory by Section 147 (Ashe and Marsden 2011).
The Great barrier reef has had many recent hardships, including water pollutants and the increasing water temperature. Although it may be too late to save this particular reef we the people must not be so nearsighted to the
“On the Atlantic and Gulf coastlines, which are made up largely of barrier islands, the beaches are eroding at average annual rates of 3 and 6 feet respectively. “1
People from all over the world go to beautiful beaches that are filled with water as clear as ice or as beautiful as diamonds. But, what will happen if we do not conserve the appealing sites that draw attraction to the public? Contaminated beaches has become a controversial issue to the public because of the causal problem, the harm to the people and marine animals, the government agencies supporting or opposing pollution, and the industries involved in creating such unlawful decisions. To create and find a solution, we must first find the core to the problem.
