Introduction

Explain how the geographical processes that are affecting the physical and built coastal environment have been managed on the Cronulla coastline. There are three geographical processes that are affecting the physical and built coastal environment, they are; erosion, deposition, and transportation. Erosion is the group of natural processes, including weathering, dissolution, abrasion, corrosion, and transportation, by which material is worn away from the earth's surface, this is mainly caused by wind, running water, and waves breaking on the coast. Deposition is the depositing something or the laying down of matter by a natural process. Transportation is when sand is moved along the coast by long shore drift. ...read more.

Deposition is also being managed at North Cronulla beach. Dune stabilization is being used to prevent deposited material from being eroded away. The plants hold the dunes together with their roots, fences ensure that the plants will not be trampled by pedestrians, ploy-mesh fencing holds deposited sand so that it will not be eroded away, and planked walkways also prevent sand from being eroded. After the erosion of Cronulla beaches in 1974, the University of New South Wales designed a new wall. It is made up primarily of interlocking hexagonal concrete blocks which way about a tonne each, which are called 'sea bees'. ...read more.

Conclusion

This method was used because it helps to build up the beach and to minimize erosion. At Wanda beach dune stabilization is used again. It consists mainly of vegetation, but the evidence of poorly kept fences can be seen. The dune profile of Wanda beach suggests that it is healthy. This can imply that dune stabilization has been successful. There is very little land-use behind Wanda beach, that is why this method has been used. It is obvious that Wanda beach is not very well looked after. This beach is not very well-managed because of two things, it is not very popular, and there is very little land use behind it. I do not know in what ways, if any, that transportation is being managed in either of these places. ?? ?? ?? ?? Joseph Wehbe ...read more.
