Narrabeen, NSW
The Narrabeen Lagoon entrance periodically fills with sand transported from storm tide events and trapped by the lagoon. This causes increased flood risk for built and recreational infrastructure during heavy rainfall and king tides, as water cannot escape the estuary rapidly. Sand is periodically removed from the lagoon entrance and placed on the nextdoor Narrabeen […]
Surfers Paradise Sand Backpass, QLD
The Gold Coast northern beaches are impacted by storms and king tides, which compromises the foreshore infrastructure and affects beachgoers. This project will build on the existing sand pumping pipeline at the Gold Coast Seaway. Currently, the existing bypass pumps sand to South Stradbroke Island; this will be extended so that sand can be pumped […]
Ramblers Road Foreshore, VIC
This project began with beach scraping in 2016 to raise low lying parts of the dune area between residential properties and the beach. This cost $30,000 and required local approvals. Revegetation of the upper dunes was then undertaken in 2018 to help contain any water that may make it across during strong storm surges. The […]
Ramblers Road Shellfish Reef, VIC
An artificial shellfish reef was installed 100m from shore, parallel to shore, built to resemble a breakwater. The reef was made from cages filled with natural rock and consolidated shell, and was then seeded with mussels. The project has successfully decreased inundation events, increased sand accumulation, and has also led to re-establishment of seagrass in […]
Adelaide Coastline Sand Pumping, SA
Longshore drift continually erodes Adelaide’s southern beaches and causes sand build up along its northern beaches. Two sand pumping pipelines were installed to enable transfer of sand back to the southern beaches without the need for carting. The Glenelg-Kingston Park pipeline pumps an average of 100,000m3 of sand per year; the Torrens Outlet to West […]
