There is a proposal for an artificial reef at Albany that could be built any day now. When it is, it is likely to become another magnet for surf travelers who will inevitably overrun the surrounding waves as well.
Designing a complex artificial reef The reef design itself has evolved from a rectangular submerged breakwater rotated obliquely to the incident wave direction and with mild seaward facing slopes merging into a conical wave focusing toe. The design used wave refraction to focus and intensify wave energy towards the shallow crest, and as a result of this, further increase wave dissipation. The crest level of the reef was set to 1.5 meters below mean sea level to make sure the reef crest remained submerged during low tide, while still being able to induce wave breaking on most swell conditions. The shape of the reef was carefully designed to make sure that wave breaking on the reef occurred in a continuous and predictable fashion suitable to most surfers.
A rubble mound rock boulder design was chosen as the best option to assure that the design shape could be achieved in construction and that its structural integrity could be assured during large storms.
not accept the shape of the bottom of the places we surf
get our local governments to crack a few rocks and make these places better
place building-waste blocks where they need to be to improve surfing spots OR better still, make places that people can’t surf into places where they can.
I can give examples but what do you think?
In NSW in the 1930s and 1940s there was a massive building, especially around Sydney, of swimming pools on the coast, they were hewn out of rock on the tidal platforms. Why don’t we do something similar to make/improve surf breaks?
The Gold Coast Council is spending more than $2 million to revamp the offshore artificial reef at Narrowneck using another 70 sandbags the size of a small bus.
It is worth looking at this article just to see the specialised boat doing the job.
They announced in June 2016 that $4.5 million has been set aside to start the Palm Beach Shoreline Project and build an artificial reef about 400 metres off Palm Beach. It is expected to take four years.
Sydney, Australia in the newly formed Northern Beaches Council Area
Following the June 2016 Black NorEaster and/or East Coast Low beach and property suffered significant damage.
Surfrider Foundation Northern Beaches was in the firing line for organising the 2002 Line In The Sand which convinced the then Warringah Council that the community was opposed to the construction of a multimillion dollar seawall over a kilometre long dumping 85,000 tons of rock on the beach at great public expense.
Seawalls profoundly damage beaches and Surfrider remains implacably opposed to hard so-called protective structures on beaches.
The Northern Beaches Branch was one of Surfrider Australia’s original branches and is still going strong 20 years on!
Major campaigns over its life include the upgrade of Warriewood Sewage Treatment Plant, protesting the proposed seawall for Collaroy/Narrabeen Beach 2002 with the famous “Line In The Sand” and thwarting the proposed overdevelopment of Long Reef SLSC on 2 separate occasions.
The branch has representation on council committees and work closely with environment centres in Manly and Pittwater.
Always looking for another face and bod to lend a hand so if you live anywhere around the Northern Beaches contact them from details on the page: surfrider.org.au/nsw
