The FlowRider and the FlowBarrel are artificial waves that are called "sheet waves". In order to create a sheet wave, water is pumped up and over a surface which is engineered to replicate the shape of an ocean wave. The result is a stationary wave in which a rider can mimic the movements of other board sports, such as moving up and down the wave, carving, and jumping. Since the wave does not move forward, the movement of the rider is derived from the water flowing over the stationary surface.
