A method and apparatus for generating a wave in a body of water may include altering a flow of water as it is urged through an inlet, contoured passage, and outlet. For example, a primary flow of water may be altered so that one or more secondary flows are created at angles to the direction of primary flow.

A wave making apparatus for creating a surfing wave in a body of water. The waves are generated using a round bottom and front mechanical plunger. The plurality of round front plungers are assembled side by side in a vertical manner on a 90 degree back wall. The individual round front plungers actuate up and down, all at the same time, at different times, in sequence and can be placed in different shaped configurations to produce a swell into a body of water which then break of artificial surfing reefs to create a wave for surfing.

Provided is a tank wave-current generation system with a rear-mounted outlet. The rear-mounted outlet and a rectifying device located below a tank are arranged, the rectifying device comprises a rectifying chamber and a built-in rectifying grid, one end of the rectifying chamber is communicated with a water collection tank, and the other end of the rectifying chamber is communicated with a bottom wall of a tank unit, an outlet in the bottom wall is located at a front end of a wave pushing direction of a wave generator, a current subjected to preliminary energy dissipation in the water collection tank is rectified into a smooth fluid through the rectifying grid and then a steady current is input into the tank, so that the current pushed by a wave pushing plate arranged on the wave generator is a steady current meeting a test requirement.

A wave pool and wave generating mechanism are disclosed. The wave pool includes a bathymetry that includes a dynamically shapeable reef along a length or circumference of a channel that defines the wave pool. The wave generating mechanism includes a foil that has a shape for bi-directionality based on an adjustment of a yaw angle of the foil. The foil can be further controlled to increase or decrease certain surface areas or other angles of interacting with water in the wave pool.
