Coastal Management In Hastings

How effective are the coastal management strategies used at present in your local beach area?

Natural disasters are considered harmful in terms of coastal management and can often cause years of work to be wiped out. It can take large amounts of sand from the beach and remove plant life. Collaroy Beach has been a victim of such natural disasters. A large storm back in 1945 caused Collaroy Beach to empty out a large percentage of its sand and damaged many structures. Collaroy Beach’s local council, Warringah Council, has taken action to prevent storm damage in the future. A revetment wall has been established on the sand dunes so waves do not cause as much damage to the dunes behind. Warringah has also purchased properties that were residential and cleared them, so that a storm will not damage as many structures.

Newhaven is well known for having a harbour arm built in 1890 and is 700m wide. The harbour stops any sediment from moving further and protects river Estuary from any longshore drift damage. The harbour also allows boats to preserve their acess to the river Ouse. Longshore drift occurs when waves approach the coastline at an angle of 45°. The sediment is then carried up the beach (Swash) at the same angle. The wave then moves back down (Backwash) at 90°. This results in a zigzag motion along the beach which transports and deposits sediment along the coastline. The formation of the cliff depends on erosion or weathering, the three main types of marine erosion include abrasion, attrition and hydraulic action. The two significant types of weathering in coastal areas are corrosion and wetting/drying. As a result of longshore drift, the sediments and shingle is transported from the sea and tends to be depostited on the oppersite side of the harbour arm. The beach is used mainly by locals of pleasure and lesuire. predict that the cliff will be

The tiny pieces of rocks broken off by weathering are called sediment or alluvium. Erosion is the process of transportation of this sediment which on sea cliffs sediments becomes part of the seafloor and is washed away with the waves. The larger rocks that are broken off by sediment as shown in this picture are called scree or talus; scree builds up at the bottom of cliffs as the rocks tumble down, these piles are called scree slopes or talus piles.

Hastings point is in a way a giant ecosystem with many living animals living within it, many of those which we rely on to pursue our day to day lives. One of these ecosystems is the Rocky Shore, the rocky shore is a great tourist destination that many marine lives live in, many of these are filter feeders, such as

Since July 2007, Docklands has been a part of Melbourne municipality. This suburb’s 200 hectares includes both land and water along with Victoria Harbour just west of the centre of the city. Thanks, to the Docklands joining forces with Melbourne, this area place a significant role for the waterfront in this location. For one thing, the harbour provides a highly modern marine experience in the Docklands that is complete with professional boat marine services. We understand so much about this are due to the fact that we provide our mobile services to the mariners who frequent the Docklands.

The following report will not only discuss the importance of the Shorncliffe Foreshore but the landscape and landforms of the area by analysing the change of the foreshore as well as the geographical processes involved.

The Tweed River Sand Bypassing Project (TRESBP) is a program which aims to allow safe passage in and out of the Tweed River, as well as transport sand to the Northern Beaches. There are several perspectives on TRESBP, and this document will be focusing on the issue from the perspective of two parties: the perspective of surfers concerned about the loss of wave quality, and commercial boating businesses glad because of the maintained, easily navigated and safer entrance to the Tweed River.

Planting sea oats, beach grass and other native vegetation to stabilize the dune line. These efforts are effective only in areas where the dune line remains in public or county owned areas. Hotels and private residential structures have frequently been built on the dunes. Thus there would be gaps in vegetation planting lessening the overall effectiveness. Also, this mitigation strategy slows the drifting of dunes, it does not prevent water caused erosion or destruction of the dune lines resulting in repeated replanting.

In 1972, the U.S. Congress approved the federal Coastal Zone Management Act (CZMA). The CZMA gives a structure for improved management of the coastal and lands and waters of the nations coastal zone. It was intended to provide broad policy direction, federal fiscal means, and legal tools as incentives to coastal states wishing to modernize their aptitude for coastal management. Participating states had to go through a planning and development stage and then submitted a proposal for approval. Most of the state programs were approved in the late 1970s and early 1980s, with ongoing implementation.

In his text To the Beach: Community Conservation and Its Role in Sustainable Development Thor Kerr presents an illustrative and case study of a large coastal development project in Southern Australia. The framing of this coastal project is indicative of production operating under the ideology of ecological modernization, which functions with the assumption that science and technology can provide the solutions to ecological crisis with the help of economic agents such as innovators, entrepreneurs and technologists (Mol 1997). Ecological modernization is accompanied by the transfer of power to knowledgeable experts who are perceived as being best equipped to develop appropriate solutions to ecological crises(). Opponents of ecological

The coast is a very desirable place to live for many people and house prices in these areas remain high. The coast gives a relaxed lifestyle with beautiful surroundings and regular opportunities for recreational activities. There are still many people who doubt that current environmental conditions will have an immediate impact on their choice to live on the coast. However this is not true, with these environmental conditions already proving destructive in areas such as Pacifica, California. This report will investigate the impacts of coastal erosion on in the lives of people living on the coast.

Furthermore there are global-scales concerns that can also be considered in the planning process, such as climate change and it’s biophysical consequences in the marine ecosystem (increasing temperature, sea-level rise and ocean acidification) (McLeod et al, 2008).

The United Arab Emirates, alongside the rest of the Gulf has reached its limit of ‘natural sustainability’. Designing for a sustainable future is no longer a choice but a necessity. The Gulf waters pose an ecological concern due to extensive offshore drilling, as well as the massive oil tanker and merchant shipping traffic, which constitute the life of the region. As development propels population growth along its shore and recreational tourism increases, the ecological well-being of the inter-tidal zones and their sea life need to be safeguarded. Global warming and the predicted rise in water levels will also impact coastal developments. There is therefore an urgent need for an integrated land/sea strategy of sustainable growth along regional/global dimensions. (Al-Manakh Book)
