Abstract: Embodiments of the invention provide a river water ride including a wave generator, a ride surface, and nozzles or jets coupled to the ride surface. The nozzles or jets can be configured to form an artificial wave upon the ride surface. Embodiments of the invention also provide an apparatus and method of forming an artificial wave that moves in a direction against current flow. Some embodiments of the invention can also be used to make a standing wave that is suitable for recreational use by causing water to flow through nozzles or jets. Some embodiments of the invention include a concave feature with a depression and a de-watering grate positioned upstream of the nozzles or jets.

Abstract: Embodiments of the invention provide a set wave system and method for use with a pool containing water up to a water level. The set wave system can include a chamber positioned lower than the water level. The chamber can include an outlet for ejecting water from the chamber into the pool. The set wave system can include an air injector positioned in the chamber upstream of the outlet. The air injector can introduce air into the chamber causing water to move out of the outlet and into the pool to form a wave.

Abstract: Embodiments of the invention provide a sheet flow wave generator including a ride surface and a plurality of nozzles or jets coupled to the ride surface. The nozzles or jets can be configured to form an artificial wave upon the ride surface. Embodiments of the invention also provide an apparatus and method of forming an artificial wave that moves in a direction against current flow. An apparatus and method of making an artificial wave can include forming an artificial wave that moves in one direction and using current moving in another direction to slow the speed of the artificial wave. Some embodiments of the invention can also be used to make a standing wave that is suitable for recreational use by causing water to flow through nozzles or jets.
