Cronulla Beach Case Study

If you have ever lived in proximity to coastal areas you may have seen coastline erosion first hand. The beaches you frequent during the summer may seem to be getting smaller and smaller every year. Why does your favorite beach seem to be disappearing? Coastal erosion is to blame. The waves, wind, tides and currents all play a part in the mechanism that is coastal erosion. When water and wind batter the shoreline sediments are carried out to sea and deposited on the sea floor or at other points along the coastline. This is called an erosional coastline. This erosion may be very apparent or seem to have happened overnight when it happens due to a large storm or extremely high tide.

One of the main ways that human’s impact coral reefs that could be avoid is coastal development that produces unsustainable tourism. Today, people are constantly looking for tropical places to vacation and adventure on these tropical islands. Since coral reefs can only be supported in tropical waters, they tend to be located by nice beaches on popular islands. The Caribbean is one of the best examples of this. Countries such as Jamaica and the Dominican Republic are generally poor countries with little development. Over the past years, these islands with tropical waters and coral reefs have began to build more and more resorts

Coastal engineering is an increasing field of importance due to the growing population in coastal areas and the trend of moving to coastal communities. Currently over 90% of Australians live within the narrow and dynamic coastal fringe (Mariani & Turner 2013). Approximately one half of the Australian coastline consists of sandy beaches and it is projected that they will be the worst impacted by the predicted global warming (Cooke et al. 2013). Increasingly, sandy beaches are being squeezed between rising sea levels and extreme weather events on the seaward side and coastal infrastructure on the landward side (Cooke et al. 2013).

Coastal management is responding in many ways due to the response of individuals, groups and governments. Australia has many impactful issues as the coastline of Australia stretches over 60,000 kilometres. With two-thirds of Australia's population living near the coastline as the benefits of the beaches and the coastal breeze attract people to live near the coast. Coastal management issues occur, such as erosion and pollution. Many places in Australia have experienced some kind of devastating problems such as the South-east Queensland oil spill, erosion at Collaroy houses and. It has resulted Australia as a nation to come together and resolve the issues and overcome them efficiently and as quickly as possible.

Reefs protect shorelines from currents, waves, and storms, helping to prevent loss of life, property damage, and erosion. Up to 90 percent of the energy from wind-generated waves is absorbed by reefs, in fact, coastlines protected by reefs are more stable, in terms of erosion, than those without. Reefs are also a natural source of sand in beach replenishment. Losing the natural reef barrier would have a large physical and economic impact on coastal communities as well as the millions of people who live in coastal areas near coral reefs. The health of sensitive coral reef ecosystems depends partly on sustainable coastal development along the coastlines the reefs protect. A study conducted in 1999 suggests that a 1% loss in coastal ecosystems leads to 1% loss of the value of the

Imagine you on the beach going to the ocean to take a swim. Ouch! All the sudden you slice your foot. But you don't know what you cut yourself on. How about litter? You want to swim in the ocean right? You can't if you litter. There are so many problems in the world, but our number one is littering. It affects us in many ways. For example you get hurt easily. There is a ton of litter on our beaches. I know this because on a website called ehp.qld.gov.au it says, "It's not only heavily-used beaches which are affected. A 1991 survey of 26 remote Great Barrier Reef islands found 5656 items of rubbish. Among the plastic, glass and metal debris were 725 glass bottles, 1066 plastic fragments, 247 aluminum cans and plastic cups, 919 thongs

Every potato chip bag thrown on the floor, every balloon released into the air, and every gum wrapper discarded on the sidewalk has an affect on our planet. In the short term we view these acts as miniscule and irrelevant, but what most of us fail to understand is that every act of pollution has a snowball effect that only harms us and our environment. Unfortunately, most of the plastic waste we throw on the floor ends up on our beaches, in our waterways, and in our oceans. Especially in Florida, where everyone is at most 45 mins from the beach, it is not difficult for trash to find its way to our oceans. Marine debris, ocean trash or ocean pollution, regardless of its many names the rhetoric still stands; every piece of litter has a ripple effect that ultimately makes it to our oceans.

Griggs, (2005a) indicated the impacts of coastal armoring. This process of passive erosion is perhaps the most significant long-term effect of shoreline armoring, and cannot be mitigated, except through an on-going and permanent beach nourishment program which is only a temporary solution. Local scour at the ends of coastal armoring structures is the result of the end configuration of the armoring structure, angle of wave approach, and wave height and period. The perception that sloping structures such as revetments have less of an impact on active beach processes due to its slope and permeability than vertical seawalls or bulkheads is the subject of on-going

The coastal management programs are very important for many reasons such as, to protect homes and businesses from being damaged and even destroyed by coastal erosion or flooding. This report will be investigating social, political, economic and environmental the natural coastal processes which are currently taking place at Palm Beach, such as longshore drift and erosion and will also focus on the impact of human disruption to natural processes. The site that was chosen to investigate was Palm Beach on the Gold Coast. While the students were at the excursion they took note of the current states of vegetation, wind speeds, primary dune developments as well as longshore drift to assess the beach and to try and find a suitable management strategy for the future. The two proposals were, A: continue current costal management strategies in terms of the Beach Nourishment Program which results in sand being pumped onto the beach and B: Construct an Artificial Reef off the shoreline of Palm Beach to minimize the impact of beach erosion to the beach. These two proposals were then examined and evaluated against the criteria of social, political, environmental and economic

The Village of Seawolf is currently under contemplation of undertaking a Stormwater Remediation Project, which will reduce storm water runoff into University Bay. As a result of the flow of this storm water runoff from the village roads and into University Bay, the local bathing beach and bed of hard clams have undergone closure for an undetermined period of time. The Village of Seawolf will vote on whether or not to undertake this Stormwater Remediation Project based on the cost, as well as if the project will be beneficial or not.

The most common of these re sea walls. They are as their name suggests, a wall of cement separating the beach from the land behind it. These are not very good because although they prevent the erosion of the land behind it, they cause the sand in front of the wall to disappear quicker. The waves are forced back on themselves and collect more debris and sand than they usually would. These sea walls also create even more erosion where the sea wall ends, because of the way the waves travel. Other cities are transporting sand in from around the country, but only to need more within a few years. The next form of erosion prevention is called at groyne. Groynes are hard structures perpendicular to the beach and are often used in groups. They can be either above water, or below water, depending on the slope of the beach. Groynes work better than seawalls at protecting beaches, but still don’t prevent beach erosion. Surprisingly, a very good way to prevent beach erosion is to plant more plants on the dunes. The plants help hold the sand and collect sand from the waves.

Management strategies of Adelaide’s beach have been taking through many activities. Management response for the loss of coastal sedimentation could start with the consideration of adapting the backshore to allow natural erosion to continue.

Coastal management responses in dealing with impacts such as erosion and pollution in coastal area is managed by groups, government, and individuals. The individual’s response to the dealing impacts such as erosion and pollution is to start cleaning up after themselves for example picking up rubbish or not littering. Group responses in dealing with impacts such as an erosion and pollution by going out of their way to help the wildlife by cleaning and saving the animals from rubbish or trash and well as notifying and making people aware of the dangerous that the natural flora and fauna that pollution has and how the natural beach can erosion which mean they are rapidly changing in structure and tell them about how dangerous the changing of the
