The invention comprises an adjustable valve system, apparatus and method using an adjustable drum assembly that can be used in conjunction with a blower or pump to drive air into and out of the drum assembly, wherein the adjustable valve system is useful in connection with operating wave generator caissons for wave pools. The present system preferably comprises an inner drum coaxially aligned and rotatably positioned within an outer drum, wherein side openings are provided on the inner and outer drums which can be aligned together to allow air to flow into and/or out of the drum assembly. That way, by adjusting the position of the inner drum relative to the outer drum, the valve system can enable the air to flow either into or out of the drum assembly and therefore the associated caisson. The system can be used to introduce positive or negative air pressure in the caisson and create waves in a wave pool.

The present invention is a shipping container water displacement activated wave generating device for use in a body of water. The wave generating device preferably has displacement forming characteristics that help to create laminar waves which then transverse a slope or artificial surfing reef to create waves which surfing maneuvers can be performed. The water displacement device is a wave container, which is oscillated up and down by mechanical means and the container displaces water to form a swell toward the slope or reefs and creates a wave for surfing.

A wave generating system can include a water channel for creating a flow of water to produce a standing wave. A water return passageway can circulate the water back to the inlet of the water channel. One or more pipes can extend under the water channel for circulating the water. A water storage chamber can be positioned below the water channel. Water can be stored in the space between the one or more pipes, and the storage water can be isolated from the water being circulated in the system. The system can produce a hydraulic circuit with hydraulic continuity so that water can be efficiently circulated through the water channel and water return passageway. The system can be modular.
