Claim:
A wave generating apparatus, comprising: a channel having a bottom, the channel adapted to direct a flow of water into contact with a bed form located in the channel, the channel and the bed form together being adapted to generate a barrel-shaped wave capable of supporting a person surfing when the flow of water contacts the bed form, the bed form comprising: a base section adjacent to the bottom of the channel, the base section having a substantially flat first exterior profile defining a first included angle between the first exterior profile and the bottom of the channel; and an upper section above the base section, the upper section having a substantially flat second exterior profile defining a second included angle between the second exterior profile and the bottom of the channel; wherein the first and second exterior profiles are arranged such that the flow of water flows over the first exterior profile and then flows over the second exterior profile; wherein the second included angle is greater than the first included angle and the first included angle is greater than five degrees and wherein both the first and second included angles are acute.
