Beach Renourishment Effective

Seawalls are also strategies that Cronulla and Collaroy implement on their beaches. However, the seawalls in Collaroy are buried under the sand and are only visible after large-scale erosion events. Whereas Cronulla beach’s seawalls are visible and reduce the scenic

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.

There are 2 types of beaches. One is erosion dominant and the other is deposition

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

Warrnambool is known for it’s many diverse areas of coastline with many unique beaches; this then brings in various groups of people and tourists in the interest of seeing the beaches or for recreational water activities to Warrnambool. This tourism is positive for Warrnambool economically, but can place a negative effect on the beach environment and the ecosystem.

Thesis statement- Coastal erosion in the Gulf South region has and continues to be an environmental

Beaches are home to many animals; unfortunately these habitats are experiencing a large amount of human impact that range from recreation, artificial lighting, development, and pollution. We are disturbing the natural habitat of these animals therefor forcing them to find new nesting sites. For example the Least Terns have been nesting on gavel rooftops because there they have the space. There aren’t many places on the beach that large colonies of bird can nest. One of the main reasons for this is continuous disturbance

Furthermore, extraction of building materials such as sand affects coral reefs, mangroves, and hinterland forests, leading to erosion and destruction of habitats. Overbuilding and extensive paving of shorelines can result in destruction of habitats and disruption of land-sea connections such as sea-turtle nesting spots. Coral reefs are especially fragile marine ecosystems and are suffering worldwide from reef-based tourism developments. Evidence suggests a variety of impacts to coastline ecosystems result from shoreline development, increased sediments in the water, trampling by tourists and divers, ship groundings, pollution from sewage, overfishing, and fishing with poisons and explosives that destroy coral

The study was published in the journal Marine Policy, which only publishes peer-reviewed articles that have been thoroughly checked, and its focus pertinent to my topic. In addition, Carter Smith, the lead author of this study is a PhD candidate at the University of North Carolina at Chapel Hill focusing her research on the benefits of living shorelines. The secondary author of the study, Rachel Gittman, earned her PhD from the University of North Caroline at Chapel Hill and is currently a postdoctoral research associate at Northeastern University Marine Science Center. She has been published on numerous occasions and is proven to be reliable.

Dr.Pikley mentions, beach Nourishment is only a temporary fix and actually speeds up erosion. They set the beach higher and this causes the break point for the wave to break sooner then it would, which as an effect slams in to the newly nourished beach harder then it would with a gradual slope or natural slope. My third perspective, Beach nourishment does more damage then it prevents, it merely exists to protect the homes of the wealthy, while damaging the habitats of many beach dwelling

Not all beaches are as beautiful as the next, but the need of help for marine animal’s lives are all the same. Each time I have been able to take a closer look into the ecosystem of the ocean by snorkeling my love for it has grown. Nature is one of the major ways I am able to relax and enjoy life and if I can do anything to make sure that humans do not destroy it I will take actions. Many people do not understand that the ocean’s fate is the same as ours. I can do a small part to make sure there is hope for everyone when I become a marine

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

The loss of seagrass and seabed instability also has a huge effect on the beach, as about a third of seagrass meadows along the Adelaide metropolitan coast have died since 1950:

Examples of construction and installation strategies that the mapping can aid in includes guidance on planting plants, installing rock features, and changing the grade or elevation of the ground (Rieger 12). The reason these steps are important is that by making the ecosystem capable, it will build a sustainability within its self, and that will eventually allow for natural unassisted restoration and stability to take place. Specifically, for coastal areas, rock features are especially important as much of the soil has faced mass erosion due to our needs and desires to modify the lands to fit our agendas. This is especially true of human created docking ports for ships and man-made beaches, common developments found within the United States
