Claim:
A wave forming apparatus, comprising: channel for containing a flow of water, the channel having an inlet end connected to a water supply, a base, and spaced side walls, a weir bed form in the base at the inlet end of the channel, and at least one additional bed form in the channel downstream of the weir bed form; each bed form having a leading end and a trailing end, an upper portion, and a downwardly inclined downstream face extending from the upper portion to the trailing end, each bed form extending outwardly to the side walls to define a primary water flow path from the inlet over the bed forms; a secondary flow passageway associated with each bed form, the secondary flow passageway having a first end communicating with the primary water flow at a location adjacent the trailing end of the bed form, and a second end communicating with the primary water flow at a location upstream of the first end; and the trailing end of each bed form having a first curved portion transitioning to a second, substantially horizontal tail portion.
