Pros And Cons Of Beach Nourishment

These strategies are sustainable and appropriate however more immediate action should be taken based on visitors’ opinions and beliefs. Coastal management strategies are simply requirement strategies like council clean ups, and does not include necessary updates and improvements in facilities and stores. This beach is lacking in short and long term major improvement plans as it’s an undervalued beach in contrast to more populated beaches. Councils and governments are putting off major plans for a small town beach which is the reason for its slow upgrade time period and lack of serious management.

This report will discuss the beach of Glenelg on the coast of South Australia. Aspects that will be elaborated on are the history of Glenelg, the location, natural processes that affect Glenelg, human impact at Glenelg, stakeholders in Glenelg, summary of management strategies that have been employed in the past and an evaluation of strategies that could be considered for the future management for Glenelg.

The Cronulla beach environment features a variety of issues that are both physical and human related; the most prominent issues are erosion, inappropriate development and also pollution. However despite the many issues present at Cronulla, there are a variety of coastal management strategies being administered in order to combat these problems that have a potentiating threat on the beach biome. The predominant strategies used to counter these problems are Seabee walls, Seawalls, and also signage, bins and fences; and these five solutions each have advantages and disadvantages, which ultimately prove whether or not, the strategy itself is successful.

Sand nourishment refers to the replacement of sediment on beaches that has previously been lost, generally through natural processes. It is a commonly used practice in coastal management. Collaroy Beach uses sand nourishment as longshore drift has moved sand, which cannot be replenished as there are rock formations preventing sediment from refilling the beach. Collaroy Beach also does not have an established dune system, and cannot trap sand.

The SURFRIDER FOUNDATION is a non-profit organization that works to protect and preserve the world’s oceans, waves, and beaches. The site shows their dedication to bringing awareness to the problems our oceans are facing, cleaning up and taking care of the beaches that are both closed, and open throughout the world. Nationwide, in just about every state, some portion of the beach is public land, which means that all members of the public have the right to use that portion of the beach. Surfrider recognizes that access to public beaches is the public’s right of access to waterways. The foundation also realizes the safety hazards of having a polluted ocean. Polluted oceans can mean dangers for swimmers and for other sea creatures that are important to us and our well-being. This beach friendly foundation is working very hard to preserve and protect our oceans, waves, and beaches and is making progress in doing so.

It has become common for sand dunes to be bulldozed to improve the views to the sea. However this destroys the natural protection of the coast. Human activities such as water transport also can cause problems for coastal areas. The dredging of navigation channels and the discharging of the material in deep water to enable larger ships to travel though water channels removes sediment from the coastal system leaving the area susceptible to erosion and will also interfere with longshore drift which will prevent the coastal beach landforms from being maintained such as the development of a spit. It is likely that a spit will be eroded and start to regress in conditions such as these.

In the other case, if there is more deposition than erosion, then the beaches grow due to more

Collaroy beach is located 16km north of Sydney’s CBD within Warringah Council's local Government Area. It is approximately 3.6 km long from the local Collaroy surf Club to the Narrabeen lagoon in the north. It had extensive development in comparison with other beaches. There are over 120 plots of land and 293 residential units within this area. Many buildings are many stories high to accommodate a large number of wealthy people. This high level of development has posed a serious risk to property due to the effects of erosion, which has shaped Collaroy beach many years along with other natural processes such as deposition. Erosion continues to occur as the land is pushed inwards at a relatively rapid pace. A year 10 grade from Redfield College

At Nudgee Beach, erosion was found to have occurred on the edges of the mangrove forest and along the mudflat shorelines. Erosion is typically influenced by natural factors and occurs when pieces of weathered rock or soil are moved – typically by wind and water – from one place to another. Shorelines with lots of sediment and sand are more inclined to be effected by erosional progression. Erosion may also be provoked and accelerated by human interference. For example, if the decision to clear trees and plants from an area is made, erosion is likely to occur as the root systems of plants work to hold the soil in place. If these root systems are removed and erosion does occur, environmental conditions – such as; landslides and flooding – are more likely to take place. Erosion may also cause other plants to tip over, have their underground roots exposed and damaged and contribute to the pollution of local waters; as a result of mud and soil runoff [26]. Erosion at Nudgee Beach was likely to have been influenced by natural factors; however, the development and extension of the Kedron Brook golfing course may contribute to the acceleration of erosional processes and further damage the mangrove

* The efforts of “Wamberal -Terrigal Beach Protection Group” have been mostly successful. Although a small part of the front dune that was covered in spinifex grass has been lost, the erosion at Wamberal would have been significantly worse.

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

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

Some amount of natural erosion is necessary to provide the sediment for beaches in estuaries and coastal bays. However, excessive erosion has occurred in the past due to development. Industrial and private development along the world’s coastlines has increased dramatically since the 1970s (Nepf). Developers and builders completed much of this construction without taking into account the effects of coastal erosion. New buildings were often placed too close to the existing shoreline so that

Replenishing of beaches may consist of pumping sand back out onto the beach, or building back up sand dunes. This would result in not enough money to replenish the beach. Only the upper part of the beach would be covered with new sand. This would create a steep beach. Creating the steep beach would increase the rate of erosion. With sand being pumped from the lagoon, or shelf, this
