Coastal Environment Field Trip Report

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 Beach is written in the style of a free verse poem consisting of two stanzas, the first one having nineteen lines and the second having twelve. The lines vary significantly in length and feature a large amount of enjambment which stretches over fur lines in some cases. The mood and atmosphere of the poem is extremely relaxed and promotes the reader to feel nostalgic about the last time they themselves visited the beach.

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

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.

The beach is a sand spit that stretches 2.8km long, linking to the sandstone of Sutherland Point at the east. Also the eastern side of the beach is the site on which captain cook first set foot on Australian soil in 1770. The beach is surrounded by various oil refineries and import terminals along with multiple houses that are alongside the road. There are a total of 13 groynes that have been placed in in the 1970’s to stop long shore drifts. At the end of the 13th groyne there is a jetty that stretches out for 1km that has been placed for the oil refinery. During the investigation both primary and secondary sources were discovered of the Silver beach at Kurnell. Focusing on the effects of pollution of the particular area, data was collected on the development and outcomes given from pollution. On the route to the beach there happened to a large industrial site rising many points regarding pollution, which will be discussed further

This investigation will be exploring whether the movement of pebbles, shingle, shells and other materials found on the beach have impacted on the shape and structure of Newhaven beach and Castlehead Cliff. One of the key processes this investigation will focus on is that of long shore drift caused by strong prevailing winds, prevailing wind is the direction from which the wind usually blows. Cliffs are made from mainly two materials, chalk which is at the bottom and sand and clay at the top. If cliffs are facing the direction of prevailing wind it may lead in high rates of cliff

Brighton, Glenelg, The West Beach Boat Ramp, Semaphore and Largs North Beach have all been influenced by hard engineering techniques. As an example, Glenelg was one of the few beaches that had some form of a breakwater along the coast. Breakwaters are notorious for having immediate impacts on the beach, but are ultimately useful in protecting the land that meets the beach. The real question is; “Do the benefits, outweigh the negatives?”. Breakwaters are

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

Hastings was chosen as an area to investigate coastal management because they had three types of hard and soft engineering. Secondly, it has a tourist industry that can be investigated. Thirdly, it has Shoreline Management Plan so the plan can be evaluated. Lastly, it Ties in with tourism and coastal parts of GCSE syllabus that are familiar and understood

Cronulla is a beachside suburb in southern Sydney, it is located 34.0574° S, 151.1522° E which is 26 kilometres south of the Sydney CBD (see figure 2). It is governed by the Sutherland Shire Council. Cronulla’s coastal environment is on the Kurnell Peninsula, which is made up of a tombolo. A tombolo is a sand spit connecting a rocky outcrop or island to the mainland. So this forms a barrier between Botany Bay and Bate Bay. The two areas of study visited were Wanda Beach and the Greenhills Beach development.

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.

The erosion of shorelines is a natural process that can have beneficial or adverse impacts on the creation and maintenance of habitats. Sands and gravels eroded from the shores of coastal bays maintain the beach as a natural barrier between the open water and coastal wetlands. Beaches move back and forth onshore, offshore and along shore with changing wave conditions. The finer-grained silts and clays derived from the erosion of shorelines are sorted and carried as far as the waters of wetlands or tidal flats, where benefits are derived from addition of the new material. However, excessively high sediment loads can smother submerged aquatic vegetation beds, cover shellfish beds and tidal flats, fill in riffle

The intertidal rocky shore of Caloundra Beach is inhabited by diverse range of biodiversity of animals and plants, many of which have developed high levels of adaptations throughout their existence. The very boundary of marine and terrestrial ecosystem, this environment is subjected to extremes of the physical environment such as temperature, desiccation, wave turbulence as well the ecological interactions that commonly occur in biotic communities (e.g. competition, predation). However Rocky intertidal shores are easily accessible by humans and provide an enjoyable opportunity for passive recreation and for science and environmental education as well.
