Coastal management The aim of this report is to investigate Long Reef and Collaroy Beach’s coastal management. Sand Dunes The Importance of Vegetation Sand dunes are a valid indication of the quality of the soil and the surrounding ocean. When vegetation is established in sand dunes‚ it stabilises it- i.e. gives the dunes structure. This structure helps prevent erosion by using the plant life to trap the sand. Without these plants (and ultimately the sand dunes) sand will be subject to many

As the coastal management expert of Southerland Shire I have come up with the most appropriate way to manage this problem. Storm surges are effects of severe storm systems due to a rise in sea level‚ if a storm surge and a tide meet when reaching the coast line severe damage can occur; resulting in extreme flooding in coastal areas‚ leading to damaging buildings surrounding the coastline. To prevent this problem and minimize storm surges having such a large impact and causing severe damage to the

Step 2 Four Focus Questions 1. How has the coast change over time? 2. What has been the impact of humans on the coast overtime? 3. Should the development continue 4. How can the coast be sustainably manage? What strategies could we use? The continental shelf‚ continental margin‚ coastal ocean and coastal zone are

erosion‚ from the sea‚ takes the sand from the sand dunes as well as the rest of the beach in a rip. The sand is then pulled out to sea where it forms a sand bar. On calmer days‚ the sand is brought back to the beach. * Storm damage can affect coastal properties. This is especially made obvious when buildings are constructed on sand dunes. When the sand is taken‚ the result on the houses is catastrophic. * Lagoons‚ which are formed where sand deposits to form a baymouth barrier at the entrance

How does coastal development impact the reefs? http://www.givethereefabreak.org/reef-facts/ * The growth of coastal cities and towns generates a range of threats to nearby coral reefs. * Where space is limited‚ airports and other construction projects may be built on land reclaimed from the sea. * Sensitive habitats can be destroyed or disturbed by dredging activities necessary for these developments. * Dredging for deep-water channels or marinas‚ and the dumping of waste

different designs; it can be used to protect a cliff from wave attack and improve slope stability and it can also dissipate wave energy on sandy coasts. Challenges /Limitations /Disadvantages However‚ a seawall may not protect a coast from erosion in the long run. As waves break against the seawall‚ the curved sea walls reflect the energy of the waves which is redirected downwards‚ to the base of the seawall‚ resulting in a strong backwash. The backwash wears away the base of the seawall‚ causing it to

undertaking my investigation in the effectiveness of current coastal management strategies at Collaroy Beach and Long Reef I have come to a few conclusions which will sustain the beach for many years to come. Whilst acknowledging the strategies in place‚ I graded their effectiveness and considered the human and environmental impacts. I investigated the issue concerning coastal erosion by doing some firsthand work at Collaroy Beach and Long Reef and by some secondary research. Some of the first hand work

Coastal Management Whilst researching about Coastal Management on Cronulla beaches‚ I have discovered that Coastal Management along the beach is required. To manage the coast we must be aware of the effect of human activity‚ erosion and decaying of the sand dunes as they destroy the beach but the Council has helped prevent these issues. One of the main issues is erosion; erosion is the process of wearing something down due to the action of water and wind. If erosion goes left unattended‚ the beach

The Issue Coastal management is the dealings surrounding the management of development along the coastline with sustainability- being able to meet the needs of future generalizations while capitalizing the use of desired areas of the coasts for residential and commercial purposes. My written report on coastal management will revolve around the main issue explored in our field trip which is the gradual erosion of the foredune on Collaroy beach‚ and its effects on stakeholders (incl. residents‚ developers
