* What management strategies have been put in place to minimise human impacts at Cronulla Beach.
Just from judging from this survey you can probably conclude that South Cronulla Beach attracts all different kinds of recreational activities from the public. This Survey was recorded in order to get a fair understanding of how the public use Cronulla Beach. Just from judging from this survey you can probably conclude that South Cronulla Beach attracts all different kinds of recreational activities from the public. This Survey was recorded in order to get a fair understanding of how the public use Cronulla Beach. Year 10 went through many forms of methodology to go about completing this investigation. We observed many things such as how people use the beach, below there is a survey of results that we recorded. South Cronulla Beach recreation survey:

As far as litter goes, we did observe that the location was quite neat and tidy, with hardly any litter in sight, and if there were any litter we saw someone from the council picking it up, they were very efficient. There were also many amenities provided at South Cronulla Beach, such as park benches, nice grass, surf club, a kiosk and a nice restaurant.
While we were at Cronulla beach we looked at some other aspects such as the sea wall that is in place, along with the techniques used to prevent erosion and flooding. You will see below a picture of the sea wall at Cronulla. The sea wall is built with two hundred of these hexagonal blocks. The purpose of the sea wall is to act as an artificial sand dune, protecting urban development that has been built close to the beach. These holes, together with the wall’s gradient are designed to absorb wave energy instead of rebounding it back with tremendous force, which could damage the wall. The sea wall has proven to be a successful stabilising strategy, for example in the 2001 severe storms, there was only minor damage to the wall. The definition of a sea wall is that they are structures used to prevent coastal erosion. They are often positioned where the frontal fore dunes were removed for urban development. The wall is on a slope to gently reflect the waves and the purpose of the hole in the centre of each hexagonal block is to soak up the water. The advantage of the sea wall is that * It prevents further erosion of the dune area and protects buildings. * Built from concrete and concrete doesn’t erode
* It is very effective because it is not wearing away
* It is also necessary because it is effectively keeping things in alignment Although there are some disadvantages with the sea wall, and they are as follows: * The base of the sea wall will be undermined over time
* It is a visual eyesore
* The initial cost is very expensive
* They require ongoing maintenance and cost.
Although there are a few disadvantages to the sea wall, I believe the advantages rule them out as this construction is highly beneficial in all aspects. There is also evidence for the success of the wall such as plants growing in the hexagonal blocks as well as the wall being there with stability for over twenty-five years.
