if your as old as DJ or myself and about 3/4 of you on this forum are , you probably heard it all before ,but after reading this on the supsurfmag.com site i thought this sounds ok ?
right now were i am Collaroy there are a few homes trying to do a Noosa and disappear into the ocean ,that would beg for this . but do you say bugger them and surf tourism can get stuffed as well after all who wants hundreds of surfers descending on your new local or what any thoughts?

ASR, LTD Announces Completion of Europe's First Multi-Purpose Reef
By: ASR, Ltd.
Monday, 16 November 2009

The New Reef is the First in the Northern Hemisphere to Revitalize a Seaside Community, Provide Coastal Protection and Foster Marine Habitat

Venice Beach, Calif. and Raglan, New Zealand - Amalgamate Solutions and Research (ASR), the world leader in the design and construction of multi-purpose artificial reefs, announced today that it has completed Europe's first multi-purpose reef on the Boscombe shoreline, just outside of southern England's coastal town of Bournemouth. The reef was engineered and constructed by ASR, who spearheads the movement towards environmentally sensitive coastal protection.

ASR was enlisted to help Bournemouth improve its surfing conditions in order to increase tourism, which is part of the town's 18 million dollar Boscombe Spa Village regeneration plan, but the new reef will provide a much more substantial benefit to the beachside community. Mimicking nature, the multi-purpose reef provides the same beach protection benefits of natural reefs - acting as a protective barrier to the coastline to help decrease sand erosion on beaches, as well as creating a new marine habitat.

"At ASR we're passionate about multi-purpose reefs as the sustainable future of coastal protection. Our beaches are facing increasing direct and indirect threats from both humanity and the natural world, with issues like global warming and the rise of the sea level," said Nick Behunin, managing partner, ASR. "While the initial investment to build a reef is often more than seawalls and rock jetties, the environmental and economic benefits of multi-purpose reefs far exceed those of the traditional methods - as beaches are protected without creating blight, marine habitat is enhanced and beach communities get socio-economic benefits from increased recreational use."

There are several unique benefits to the creation of multi-purpose reefs as it pertains to coastal protection:

* Reefs decrease the rate of erosion on beaches by dissipating wave energy before it has a chance to hit the beach
* Reefs create marine habitat and increase ecology
* Reefs can be designed to create a recreational amenity like surfing, diving and fishing
* Reefs are submerged offshore structures, supporting the natural beauty of the beach and ocean, unlike prominent seawalls or groin structures, which can be unsightly and create blight

"The Boscombe Spa Village project already produced a rise in tourism, even before the completion of the reef, re-establishing Boscombe to its rightful place as a leading destination beach resort. An affluent surfer market is attracted to the area, and as a result, jobs have been created, the seafront transformed, a new water sports facility built and a community revived. The reef is a perfect example of how an innovative free-to-use project can have such a positive ripple effect in an area," said Roger Brown, Director of Leisure Services, Bournemouth Borough Council. "While the reef will improve wave quality for surfers, it's exciting to know that there are underwater benefits too, as sea life, including cuttlefish and spidercrabs, have already been making the artificial surf reef at Boscombe their home."

What is a Multi-Purpose Reef?

Using cutting-edge biomimicry technology, multi-purpose reefs provide protection to shorelines in order to prevent sand erosion, while simultaneously enhancing the under-water ecology and creating a recreational amenity for fisherman, divers and in some cases, surfers.

Multi-purpose reefs are constructed under water outside the shoreline, in order to protect the beach from wave action. The construction of reefs is highly specialized and uses geo-textile bags, weighing upwards of 2,500 tons that are secured to a base that is anchored to the ocean floor. Sand is then pumped into the bags, as divers monitor the process from the sea floor to ensure design requirements are met. Construction must be conducted during perfect weather conditions and while the ocean is flat and calm.

The reef does not create waves, but instead acts as a ramp that changes the way the waves break - it harnesses existing wave energy that used to break on the sand, causing erosion, and channels it to break on the offshore reef instead. As a result, the beach is protected, ecology is enhanced, and improved conditions are created for surfers, divers and fishermen.

About ASR, LTD.

Amalgamate Solutions and Research (ASR) is the global leader in both the design and construction of multi-purpose reefs with more than 30 years of experience, numerous awards and patents. ASR also provides a range of consulting services, including numerical modeling, sustainable marine farm studies, wave energy projects, biological monitoring, research-based technical investigations, baseline surveys, larval dispersal, ecological surveys and assessment, and has worked with the largest desalination plant in the southern hemisphere.

The ASR philosophy is to Understand, Innovate, Sustain. Before undertaking a new project, the company's first priority is to understand the natural processes governing a specific project site. This knowledge is then used to develop an innovative and sustainable solution to the problem - this approach is always the same whether the problem is erosion, sediment transport, effluent dispersion, ecological impacts, environmental impacts or poor surf.

All sounds very lovely , come to the Gold Coast and have a look at some work by the best in the country , a clear 10-0 victory to nature .

I'm all for artifical reefs but I'm sick of the waste of money on the projects so far. They should line up a row of old ships and just sink them.

Just read Daleators link back to Cables Artificial Reef at near Cottesloe WA.
Gee Cammo as project manager I think you would be on your own calling it a success!
I was just looking for some info on the design the other day.The interesting thing I note as I look out most mornings is that at low tide when every other reef in the metro area and Rottnest is fully exposed ,the Cables Articicial reef is fully and I mean fully submerged.
It needs a 3.5-4m+ swell to break and as we all know that happens roughly 4 times per year.
Did it sink?

Agree it was pointless behind Rotto what were you thinking???

Lots of rumours out there about the project running out of money, any truth in that? Or were they scared of litigation if someone hit the reef?

And the Goldy has shown that just about everytime you mess with nature there is a downside somewhere along the line. Disrupt the natural flow of sand and someone eventually suffers, usually the next beach up. Pretty soon you have a coast line dotted with man made objects to trap and alter the flow of sand.

Then, just to remind you how insignicant you really are, mother nature turns on a show of force and changes the landscape completely.

Budget for cables was cut in half...so they designed it to make best use of sand flow and for the reef to grow naturally over time...unfortunatly they put it in a **** spot and the sand hasn't done its job...
