Coastal Management Long Reef Notes Geography
The aim of this report is to investigate Long Reef and Collaroy Beach’s coastal management.
The Importance of Vegetation
Sand dunes are a valid indication of the quality of the soil and the surrounding ocean. When vegetation is established in sand dunes, it stabilises it- i.e. gives the dunes structure. This structure helps prevent erosion by using the plant life to trap the sand. Without these plants (and ultimately the sand dunes) sand will be subject to many natural forces without protection, meaning any major storm could theoretically remove large amounts of sand from the beach with no natural means of replenishing it. Long Reef Beach is commendable in the amount of vegetation it has produced. …show more content…
Due to natural processes, Collaroy Beach is progressively losing its sand, which is presently being replenished periodically using sand nourishment. The Warringah Council should continue its sand nourishment; however it should not look to it as a permanent solution. Warringah Council should be developing methods of introducing more vegetation in the area, so sand can be trapped over time, overcoming longshore drift. It should be noted that Long Reef beach can be considered an exemplary
