HALO in the tank in Vicksburg, MS

Elemental Innovation, Inc., conducted a series of experiments at the US Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory (CHL), on a scaled model of a version of their Halo® Wave Attenuator.

The purpose of the experiments was to determine a configuration of the modified
Halo® units that could be used as a wave absorber in a wave research basin.

The wave research basins at CHL are rectangular concrete basins with a wave
generator at one end. Wave absorbers are used to reduce the wave energy
reflecting off the sides and ends of the basin. Ideally, the wave absorber is placed in front of the basin walls, wave energy is converted to turbulence as it passes through the wave absorber, and the remaining wave energy that reaches the basin wall is unable to pass back through the wave absorber into the center of the basin.

Unlike a wave absorber on the open coast, the wave absorber in a basin must reflect an absolute minimum of wave energy. Transmission though the wave absorber should be uni-directional towards the wall but not returning towards the basin center.

A determined configuration of the modified Halo® units provided reasonable wave energy absorption in the test basin. The configuration used multiple rows of modified Halo® units with graduated openings such that successive rows of units had less open area as the rows neared the basin wall.

Unlike conventional systems, HALO wave attenuators are eco-friendly, low maintenance, and portable. They also offer twice as much protection.
