Coastal Management Report: Collaroy 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, specialist groups). This report will also include the decision making processes considered by the management (both local and state), as well as the descriptions of their actions/strategies, and thus the results of their policies.

The LocationOur site of interest, Collaroy beach is located in the suburbs of Northern Sydney, in the state of New South Wales, Australia. Collaroy is part of the local government area of Warringah Council and part of the Northern Beaches region. Collaroy is well known for its excellent surf beach which joins with Narrabeen Beach in the north and Long Reef and Dee Why Beach in the south. Also in close proximity is the Dee Why Lagoon as well as the Long Reef Head.

Collaroy beach is the most highly capitalized shoreline in the Warringah local government area, featuring beachfront houses and apartments built on the edge of the sand including the famous Flight Deck Apartments.

.

Geographical ProcessCoastal erosion is the loss of land along the shoreline due to the natural removal of beach and dune material in response to changing wave and water conditions. Buildings and facilities located within the 'active' beach system, or areas subject to coastal erosion can be undermined and may even collapse.

Approximately 60 percent of the NSW open coastline is characterised by sandy beaches. These beaches are dynamic environments undergoing continual cycles of erosion and accretion in response to the action of tides, wind and waves. In many

    New Jersey is often used as an example of a natural system gone awry. The unflattering term "New Jerseyization" was coined by a prominent scientist to describe a developed, eroding coast, where natural beaches have been replaced by engineering structures. This view may have been correct in the past, when seawalls and bulkheads replaced many of our beaches, but our beaches are being brought back by artificial nourishment projects. Hard protection structures are only one phase in the cycle of changes on a developed coast. Human efforts can help regenerate landforms and biota, providing we take a proactive approach to shore protection that accommodates a wide range of resource values. The preferred method of shore protection in New Jersey has changed from groins, to bulkheads and seawalls, to beach nourishment. Hard protection structures are less likely to be built in the future, but many structures still exist, and some new structures may have local usefulness. Accordingly, it is important to know how these structures function. It is also important to know that all protection strategies have usefulness, but they are not readily interchangeable at a given location. Beach nourishment can help restore lost natural values, but many municipalities have elected to grade and rake their nourished beaches, preventing them from evolving into topographically and biologically diverse natural environments. The large amount of sand scheduled to be pumped onto New Jersey beaches in the future represents an invaluable resource, but the full potential of nourishment will not be realized without addressing habitat improvement and nature-based tourism in addition to the goals of protection from erosion and flooding and provision of recreation space. A dune is another valuable natural resource that is often overlooked. Dunes provide protection from flooding and…

    These are examples of how humans have physically impacted the beach and its structure. The flight deck is a human residential block of units on the edge of the beach. This unit block has massively affected the shaping and the beachfront of that area of Collaroy beach. The coastal processes that are threatening the erosion of the beachfront developments are, Erosion/Accretion Cycle (or sediment budget), destructive storm waves and king tides. These processes are slowly undermining the building and causing the dune under the units to become unstable and dangerous for people living in and around them. Also the salts from the waves blowing onto the units causes the metal to rust and the foundation of the building and balcony handrails to be at risk of being unreliable and…

    Long Beach Island Case Study

    • 10 Pages

    Long Beach Island is a barrier island located approximately one mile off of the southern coast of New Jersey. The island in some areas is only a half-mile wide, with some areas, which are even narrower. Therefore, coastal erosion and flooding are both major concerns for the residents. Most of the island’s eighteen miles of beaches have experienced significant damage from erosion in recent decades. The damage is not only threatening the multimillion dollar homes in the area, but others also believe that the island will eventually become one with the Atlantic Ocean. However, in 2005 the Army Corps of Engineers began work on a $75 million dollar project to build a dune the length of the island. To analyze the severity of beach erosion on Long Beach Island, the following report compares the conditions to the Grand Strand off the coast of South Carolina. Both areas are experiencing many negative factors, which are contributing to the deterioration of the sandy beaches. The conclusion points to the fact that however short-term beach replenishment may be; it is the most viable option to solve the current devastation of beach erosion.…

    * The sand dunes on the beaches. This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present. The main type of 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.…

    The finest beaches on the Mississippi Gulf Coast are located on Ship Island and are being eroded however; erosion is the thing that initially created the beaches. There were no beaches when oceans first covered the surface of the earth millions of years ago, only rocky shores. Over millions of years these solid stones were broken down into rocks by erosion, then were broken down into pebbles, and then into gravel, and then into sand. Rivers also carried down sand and silt from the mountains and deposited it into seas around the world and oceans. I found out that most causes of beach erosion are natural and the rest is because of man made structures. Jenny Lazlo of the National Awareness of Erosion was interviewed by one of my team members and stated that “everyone likes waves but they actually contribute to the erosion of beaches. Formations of waves are caused by wind, the rotation of the earth, and deep ocean currents.” Water moves in circular paths perpendicular to the ground. Waves take sand from the depths of the ocean and deposit it on the beaches. They also carry little pebbles and stones, and smash them into each other which create sand. Living on a beach or nearby one can be extremely harmful to humans because large waves can form (are powered by storms) and break into the beach washing back down much more sand with them to the ocean. A major part of beach erosion is ocean currents. Ocean currents can make and break the shore, depending on the circumstances but in this case it erodes the shore. “Long shore and near shore currents (riptides) are the two main types of currents that shape up beaches. The creation of the near shore current is when waves hit the beach at a ninety degree angles, they are very strong, narrow, and flow perpendicular to the beach in the seaward direction. This allows them to carry away large amounts of sand.” says Adam Copeland Erosion Researcher of Cornell University. Long…

    Integrated coastal management may include soft options as well as hard defences. This is where the whole of a coast within a sediment cell is managed - it also focuses in not just sea but land to make plans more sustainable. Numerous players/organisations are involved in shoreline management plans – this can be a negative because it can be difficult to coordinate and manage, decisions making is harder/longer, there could be a lack of consistency in the collection and storage of data, its hard to choose which players opinions are more important and also political boundaries don’t match natural ones.…

    Goldcoast Erosion

    In recent decades erosion has become a major issue to beaches around Australia, since beaches are temporary features. There is always sand being removed and sand being added to them, often, they change drastically during the year, depending upon the frequency of storms. Eventually, a beach erodes because the supply of sand to the beach cannot keep up with the loss of sand to the sea. The Sand dunes and vegetation help to hold the sand in place when wind or water tries to erode it away. The environment can be affected by erosion in several ways. First and the most obvious, houses that are built along the shore are at risk of being washed away if more sand is being removed from the beach in the winter, and not enough sand is returned in the summer. Secondly, animals that live on the beach are at risk for losing their homes. The amount of sand on the beach, and how it is deposited can also affect the shape of the shoreline, which can have an effect on the type of waves that are produced at the beach. The type of waves produced at the beach will also ultimately have an impact on beach erosion.…

    What do you do when mid-latitude cyclones get larger, strong frontal winds are more frequent, and waves and currents get stronger? How can we control high waves and storm surges that drive more sediment transport, permanently changing the coast? Coastal dunes, of all shapes and sizes, are are dense enough to prevent rapid and significant changes. The Coastal Zone Management Act of 1972 specifically calls for the creation and enhancement of dunes in the coastal zone. There is increasing recognition of the variety of dune features that exist at the coast and the interplay between the beach and coastal dunes. The measurements of sand gains and losses in the dunes and the flows of sediment from the beach to the dune have been practiced along many shorelines. The research has led to a series of site-specific descriptions and categorizations of dune types and their interaction with local dynamics. In 2011, the Congress spent 56 million dollars supporting such projects (Coastal Zone Management, 2008). Some of the projects include dune stabilization, the mining and study of dune composition, sand fencing, and beach nourishment. Jetties and groins are being built to capture sand that would normally have been washed miles away. These methods are used all over the world and they help to prevent accelerated shoreline alterations. Preserving the shoreline also protects certain species in the biosphere like Sea Turtles, rare birds, and important plants. These are some of the few wise environmental choices we are making with money these days.…

    The second strategy is to install a network of paths and barriers to prevent people from shifting the sand dunes. Surfers often check the conditions of the beach by looking over them at the dunes. They run up to the top of them so they can get a view of where there are good waves or not. In summer, an astonishing number of surfers will flock to the beach. The result of those people all running up the dune would cause displacement of the sand and weakening of the dunes. To solve the need for people to travel around the beach, the council has installed walkways to provide a path around the area which doesn’t involve people walking or treading on the sand dunes. The dunes have been fenced off in case any people wonder off and don’t walk on the pathways. On top of that, board and chain stairs have been put put in to protect the sloped areas of the beach which may be vulnerable to deformation. Finally, polymesh has been laid over areas of bare sand to stop sand blowing…
