Listshore Drift and GroynesHow do groynes prevent littoral drift?TKSBBy: Saksham YadavLideshore Drift and GroynesIntroductionObjective:To determine how groynes prevent littoral drift.The problem:Lideshore drift influences deposition and sediment erosion. Waves erode the coast and carry the eroded material along the shoreline. Over time, the materials will settle onto a beach or form a larger feature such as an spire. Groynes are structures built at equal intervals along the coastline. Their aim is to limit longshore drift, thereby preventing coastal erosion.Figure 1 - Google MapsAbout the location:The location of the study area is Silver Beach on the Kurnell Peninsula, near Cronulla. It is located in the Shire of Sutherland, south of the Sydney central business district (CBD) and just south of Kingsford Smith International Airport. The area also has historical significance as it is close to where Captain James Cook landed on April 28, 1770 at Botany Bay. Figure 2 - Close-up of the study area, Silver Beach is located just on the border of Captain Cook DriveFigure 3 - Captain Cook Monument, taken by Saksham Yadav on 25/2/14 at Botany BaySignificance of the problem: Longshore drift is a process by which sediment is transported from one place to another. When this process occurs, beaches, spits, and sandbars build up over time. If the process of longshore drift is altered by factors such as stronger winds and currents, beach erosion begins at a faster rate, which can lead to many serious problems. The main players in littoral drift are the owners of seaside resorts. They rely on people to visit their resorts and enjoy the beach. However, if longshore drift is eroding...... middle of document ...... consider some ideas on what can be done to further improve management of the coastal issue. Using the Research Action Plan, I aim to gain a sophisticated understanding of littoral drift, coastal management and the implementation of coastal issues, through the Research Action Plan. Most importantly, I will include various diagrams explaining how the process of longshore drift occurs and what its implementations are on coastal environments, accompanied by an explanation of how the problem is managed, a detailed overview of the geographical processes involved and a discussion of the impacts of the problem and why it is important.
