Wave Attenuating Fringing Reefs

Picture 1

Subcon’s vision is Enabling Ocean Communities to Thrive. At Subcon, we engineer solutions that benefit ocean communities. Our Wave Attenuating Artificial Reefs (WAFR) make this vision reality. We have designed, tested and deployed wave attenuating fringing reefs (WAFR) at multiple sites including Mon Choisy, Port Coogee and Innisfail and the modules have also been used to provide habitat at Esperance, Perth, Carnarvon, Darwin and Exmouth. Our track record in the design and installation of engineered reefs is unmatched!

Bombora Reefs have been used in a broad range of applications, from breakwater enhancement, erosion control, fisheries enhancement and decommissioning.  Their value in wave attenuation and habitat enhancement is demonstrated and well understood.

The design of Bombora builds on our extensive experience with engineered reef substrates and incorporates specific wave attenuation design to combine coastal protection with marine habitat enhancement. In 2021, Subcon tank-tested the Bombora’s at UWA and UTas to determine their effectiveness in wave attenuation and to optimise the design. You can learn more about the research project in the video below or by contacting one of our engineers on our contact form.


We have two installed WAFR’s, one in Western Australia, and the other in Mauritius.  Please see Case Studies below for more details.

Wave Attenuating Fringing Reef (WAFR) physically knocks high waves down to smooth the water.

They also remove energy from an ocean swell. On the ocean side of a WAFR the oceanic swells carry sand in suspension but due to the reduced energy of the wave, the sand typically falls out of suspension and settles on an beach.
