Abstract: Provided is a system for generating circular steady water waves for sport activities. The system comprises a ring-shaped water pool having inner and exterior rings and a floor inclined from the outer ring to the center of the water pool. The system comprises channels located under the floor of the water pool for recirculating water. At least one water propeller turbine is installed inside the channels and configured to recirculate water from the water pool through the channels and back to the water pool. The system comprises guiding plates installed on the floor. Waves of different shapes including breaking waves are generated by varying velocities of different water current and controlling guiding plates.
