Wave generating system

A device for discharging water drawn from a make-up supply of water to a body of water, said device comprising:

• an elongated tubular chamber having a substantially closed rear end and a substantially open front end;
• an anchor securing the chamber below a surface of the body of water and for maintaining the tubular chamber in a desired orientation with respect to the body of water, such that the body of water is in fluid communication with the tubular chamber via the open front end;
• a supply of compressed air fluidly interconnected with the rear end of the tubular chamber;
• and
• an air control valve in fluid communication with the supply of compressed air for operatively controlling the flow of compressed air into the tubular chamber,
• a supply of make-up water fluidly interconnected with the rear end of the tubular chamber;
• wherein actuation of the air control valve releases the compressed air into the rear end of the tubular chamber to forcibly expel water within the chamber out of the open front end into the body of water;
• and
• wherein in the event that the chamber reaches a predetermined low pressure after the release of air into the rear end of the chamber, the supply of make-up fluid introduces fluid into the rear end of the chamber to relieve the low pressure and to fill the chamber.
