Wave basin

Personalise
WRL's wave basin is used for wide range of coastal studies including coastal structures, breakwater and harbour models and beach morphology investigations. Our basin underwent a complete rebuild in 2022 increasing in size, depth and capability, creating a coastal investigation facility unique to Australia. Our basin is capable of testing long-crested or short-crested waves, sensitivity testing to a range of wave directions, for both operational or extreme wave conditions; using our segmented wave maker.

WRL’s wave basin is equipped with state-of-the-art instrumentation including multi-element random wavemakers with active wave absorption, resistive or capacitance wave probes, 3D laser scanners.ÌýThe permanent floor of the wave basin is constructed of concrete, although a site-specific 3D bathymetry is typically constructed on top for each project using a combination of laser cut 2D transects bathymetric profiles and gravel fill with a fibre reinforced concrete capping to allow proper representation of natural wave propagation processes.

Additional passive wave absorbers are installed around the perimeter of the basin to remove unwanted wave reflections, enhancing the overall quality of the generated wave conditions. Optional solid walls can be installed along the east and west sides of the basin to improve the quality of the long-crested wave fields.
