Introduction
The coastal environment of one of Australia’s most inhabited places on our land. Currently 85% of Australia’s population lives along the east coast of Australia and people are uneducated about the impacts that they are having along the coastline. With the population increasing everyday the coastline is receive huge pressure to sustain, and further develop the area. Many management plans have been put into place along the coastal areas around Narrabeen Lagoon and beach. These include dune rehabilitation,

The report has also been accompanied with information learnt and known beforehand and after the excursion. The field trip entailed us going to sites such as, Narrabeen lagoon and beach, Collaroy beach, Long Reef Headland and Fisherman’s beach, which where able to show us what sort of human and natural processes have taken place, especially over the time of the recent storm due to the easterly low. At Narrabeen lagoon we learnt about the rock-training wall and the process it has in assisting with water flow. We walked up to a viewing point that gave us a look at Birdwood Park and the re-built and re-vegetated sand …show more content…
Currently 85% of Australia’s population lives along the east coast of Australia and people are uneducated about the impacts that they are having along the coastline. With the population increasing everyday the coastline is receive huge pressure to sustain, and further develop the area. Many management plans have been put into place along the coastal areas around Narrabeen Lagoon and beach. These include dune rehabilitation, sand replenishment and the introduction of the rock-training wall in 1982.
This report will be based upon fieldwork conducted on the 5th of May 2015, along the Narrabeen coastline. It will cover questions such as what has been done to stabilise and reduce the effects of natural processes.
1. Destructive waves causing the largest wave cut platform in the Southern Hemisphere along Long Reef Beach
2. What has the Warringah Council has done with the addition of hard engineering and the process of dune rehabilitation with the plantation of spinifex grass and mass movement of grass.
Throughout this report, I hope that there will be conclusive evidence that the questions raised will be answered with thorough
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)
Investigating the Geographical Processes that are Affecting the Physical and Built Coastal Environment There are three geographical processes that are affecting the physical and built coastal environment, they are; erosion, deposition, and transportation. Erosion is the group of natural processes, including weathering, dissolution, abrasion, corrosion, and transportation, by which material is worn away from the earth’s surface, this is mainly caused by wind, running water, and waves breaking on the coast. Deposition is the depositing something or the laying down of matter by a natural process. Transportation is when sand is moved along the coast by long shore drift. At North Cronulla beach erosion is evident.
Investigating if Dawlish Warren is Under Threat of Human Impact My investigation aims to find out if Dawlish Warren is threaten by human impacts and marine processes and are these affecting the ecological and economical value of Dawlish Warren. I will put to test Butlers Model and see if it applies to Dawlish Warren. I will also look at the other side of the argument and see the effect of management in Dawlish Warren and look at the sea defences which have been put in place to prevent erosion and longshore drift from occurring and also protecting the Railway line.
cut back on the problems in the Bay. Scientists have given an unthinkable amount of attention to the Bay of the past several years and researchers from countless numbers of agencies and institutions have dove deep into the issues and studying every nook and cranny to create answers to every politicians’ questions. The biggest concern with the Bay, and the most concentrated ...
... consider some ideas of what can be done to further enhance the management of the coastal issue. Using the research action plan, I aim to acquire a sophisticated understanding of longshore drift, coastal management and implementations of coastal issues, through the research action plan. Most importantly, I will include various diagrams explaining how the process of longshore drift occurs and what implementations it has on coastal environments, accompanied by an explanation of how the issue is being managed, a detailed outline of the geographical processes involved and a discussion of the impacts of the issue and why it is important.
The Coorong National Park is a protected area located in South Australia 156kms southeast of Adelaide. (See Figure 1) It forms part of the Murray Darling river system and is situated close by to Lake Alexandrina and Lake Albert. The Coorong stretches for more than 130kms and protects many saltwater lagoons of which are sheltered from the pounding surf of the Southern Ocean, by the sand dunes of the Younghusband Peninsula. The Coorong, Lower Lakes and Murray Mouth all form part of a unique wetland environment, consisting of 23 different wetland types ranging from freshwater to hypersaline, dense vegetation to open water and temporary to permanently inundated land. These features contribute to the Coorong, area meeting 8 of the 9 criteria for classification as a ‘Ramsar Wetland’ (See Appendix 1) The Coorong area is classified as a Mediterranean Warm biome with a Mediterranean climate featuring temperatures ranging
This report thoroughly details the present and future uses and management of The Spit and how these developments may affect the Gold Coast community, culturally, economically, politically, environmentally and socially. Throughout the report, primary and secondary evidence will be provided justifying if the Queensland Government made the right decision of rejecting the ASF Integrated Resort proposal. This report will discuss existing countermeasures used to preserve the Spit, natural and man-made.
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,
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.
One such location is Cardiff Reef in northern San Diego County. The wave is shaped by a composite reef of rocks covered in eel grass and surf grass. This reef and the kelp forest outside of the reef are sensitive biodiverse marine environments facing threats from rising ocean temperatures, overfishing, and other damaging human activities. Garth Murphy, a former member of the California Department of Fish and Game’s Marine Life Protection Act Initiative Regional Stakeholder Group and surfer, explains “Over-exploitation and depletion or collapse of important food web components causes imbalances that degrade marine ecosystems…diminishing water quality and habitat suitability for marine life and surfers.” In addition rising sea levels could negatively impact the surf and habitat by causing the reef to be in deeper water.

The federal and Queensland state government have both promised to protect the reef. Queensland Labour government has created a plan to protect the reef called “Reef 2050”. However, Reef 2050 has more ambitious water quality goals than previous plans, but even less funding. The plan has been endorsed by the World Heritage Committee, but specifically told the governments to come back with an investment plan and that it is a matter of priority as the plan would cost billions of dollars to achieve.
While those traveling from afar have always known Australia for its beaches, her outback regions and the great metropolitan centers of Sydney and Melbourne, few have experienced the wonders of Lake Macquarie. Being flanked on all sectors by beautiful sandy white beaches, majestic mountains and the deep blue sea, a near perfect sub-tropical climate makes this a destination of choice for native Aussies and foreign visitors alike. Visitor Information Situated in the Hunter Region of New South Wales, an area of 110 square kilometres, or 42.5 square miles, connects it to the Tasman Sea by a short channel. This proximity to open waterways makes it most convenient for the residents of the City of Lake Macquarie that live near the shores of the lake.
Coastal Erosion, Coastal Transportation and Coastal Deposition are natural processes that have occurred at Muriwai's coastal geographic environment. These processes outlined have formed such phenomena as Motutara Island (stack), Otakamiro Point (headland/cliff), Fisherman's Rock (shore-platform), cave and the blowhole.
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.
