A wave forming apparatus has a channel for containing a flow of water with 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. Each bed form has an upper portion and a downwardly inclined downstream face extending from the upper portion to the trailing end. A spoiler is provided at or near to the trailing end of each bed form. A primary flow path for water extends over the bed forms. The trailing end of each bed form may be an extended flat tail.
