Abstract
Hydraulic jump water displays and methods for creating the same to provide attractive and varying displays are disclosed. In accordance with the method, water under pressure is expelled in the form of a thin sheet across a substantially flat, approximately horizontal surface bounded at the opposite end thereof by a very small dam, preferably water pool therebelow. By varying the water pressure of the source, a hydraulic jump may be created in the water backing up from the dam, which hydraulic jump may be caused to move in either direction, with the water flowing over the dam, ranging in quantity from essentially none to a substantially surge depending upon the direction or motion of the hydraulic jump. Appropriate control of the water supply pressure will generate relatively non-repetitive displays. Various embodiments are disclosed.
