1. A method for generating waves in a pool of water, comprising:
providing a pool containing water;
providing a wave generator the wave generator having two or more chambers, a set of valves comprising a position-controlled egress valve and a position-controlled ingress valve in each chamber of the two or more chambers, and a water height sensor in each chamber of the two or more chambers;
providing a control system in communication with the water height sensors and each set of valves;
sending to the control system information from the water height sensor located within each of the two or more chambers located along a first side of the pool, wherein the two or more chambers are in fluid communication with the pool and are configured to selectively retain water from the pool and release water to the pool to generate a wave therein;
determining, using the control system, a measured water height in the two or more chambers, based on information correspondingly received from the water height sensor in each chamber of the two or more chambers;
calculating, using the control system, for a first chamber:
a difference between the actual first chamber water height and a first chamber first set water height;
a first chamber first valve angle for a first chamber first valve in the set of valves in the first chamber wherein the first chamber first valve angle is operable to fill to and maintain the first chamber first set water height; and
a second valve angle for a second chamber second valve in the set of valves operable to allow gas to enter the first chamber to transfer water out the first chamber to reach a first chamber second set water height; and
concurrently sending a signal from the control system to the first chamber, the signal comprising a first set of instructions and second set of instructions to each valve in a first set of valves, wherein the first set of instructions instructs each valve to selectively adjust a first valve angle based upon the actual water height in the first chamber to fill the first chamber to the first set water height, and the second set of instructions instructs each set of valves to selectively adjust the second valve angle to the second set water height to introduce gas into the first chamber to expel water from the first chamber to generate a wave having a desired shape.
