of these issues includes erosion. Erosion is one of the biggest geographical issues‚ which is the wearing down of different materials‚ such as rock‚ soil and sand. Some of the few management strategies used to provide a better environment are sand dunes and the sea bee wall. Erosion is the wearing down of different materials caused by natural forces such as long shore drift‚ waves and tides. These forces erode the landforms‚ which can cause landslides. Landslides will demolish the infrastructure

coast? Coastal dunes‚ of all shapes and sizes‚ are are dense enough to prevent rapid and significant changes. The Coastal Zone Management Act of 1972 specifically calls for the creation and enhancement of dunes in the coastal zone. There is increasing recognition of the variety of dune features that exist at the coast and the interplay between the beach and coastal dunes. The measurements of sand gains and losses in the dunes and the flows of sediment from the beach to the dune have been practiced

is something we call “Dunes Day‚” or as I like to call it “Doomsday.” This is the day in the middle of camp‚ right when the fatigue from running twice a day kicks in‚ where we face the treacherous and never ending hills of the Sleeping Bear Sand Dunes.

Recreational activities like four-wheel driving places pressure on the coastal environment if it is not carefully managed‚ large dune areas and beaches where vehicles are given access can be highly susceptible to erosion. Population growth is the overdevelopment and rapid growth of coastal areas occur due to the current Australian trend for people to move from large cities to

on the sand dunes and rocks on the coastline of Terrigal and Wamberal. Some people have caused more pressure on these areas as they have built housing such as at Stop 7‚ “The Ruins” Wamberal South. Many of the people that lived on the beach have tried to find ways to stop most of the erosion from waves and wind affecting their land and housing. On the beach we saw many strategies that are effective in their own ways but not permanent. One way was to plant vegetation on the sand dune‚ this has effect

shrunk into a mere isolated island. There is destruction everywhere. Road works are left unfinished‚ doors of houses are left open and there is no one. In the foggy and dim distance several buildings rise with dignity and pride‚ above the dancing sand dunes and several others are prisoners of the black smog that beseiges them.

to investigate Long Reef and Collaroy Beach’s coastal management. Sand Dunes 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
