The Webber Wave Pool system involves two types of water displacement: one to make waves, the other to make currents.
The hull drive system is composed of a looped steel rail TRACK onto which the wheeled carriages are attached. Each CARRIAGE is suspended underneath the track, like a carriage on an urban monorail system. By using electric MOTORS to drive the carriages and nitrogen filled rubber tyres on the rails, noise is virtually eliminated. The hull is attached to the carriage by HYDRAULIC actuators which then move each hull to make changes to the wave size and shape. Software controls the speed and the draft and the angle of each hull. Small changes in these three elements, brought about by the software, result in immediate changes to the wave size and shape.
When waves break in an open environment like at an ocean beach or in a closed system like a wave pool, currents will form. And the turbulence and swirling that results can severely limit the potential wave rate while waiting between waves for the water surface to settle. In our wave making system we have developed a method of not only controlling unwanted current to thereby maximise wave rate, but also to create controlled and desired water movements to enhance the way the wave breaks.
