Abstract: The mobile sheet flow water ride apparatus of the present invention utilizes a rigid inclined structure. Ride surfaces, aisle surfaces, and surround fences are covered with protective inflatable air cushions. The ride apparatus of the present invention has non-retractable transport wheels and uses a multitude of adjustable jacks to take the load off the transport wheels and support the ride apparatus. The ride apparatus utilizes a 15,000 gpm double-suction pump driven by a 460-horsepower diesel engine that is transported in its own trailer. Water is pumped from a main storage tank through a horizontally-oriented nozzle that 2.438 meters wide and 6.35 cm high at supercritical speed. The water rushes up the slope, over a berm at the top of the slope, and back into the main storage tank through a square main return grate.
