The present disclosure relates to a method of using a feedback loop from sensors to manipulate sea waves by applying concepts from optics interference and lensing. The method includes capturing, by one or more sensors, environmental data of an aquatic environment, wherein the environmental data relates to one or more of a wind speed, a wind direction, a wave pattern, a wave spectra, and a wave direction. The method includes analyzing, by one or more processors of a controller, the environmental data to identify a sensed environmental condition. Further, the method includes determining an optimal configuration of a wave interference device in the sensed environmental condition, wherein the controller is communicatively coupled to the wave interference device; and configuring the wave interference device to occupy the optimal configuration.

Single-door flap gates and double-door flap gates are disclosed. Flap gates of the inventive subject matter are coupled with a structural element by one or more linkages, where hinges that are coupled with the structural element allow flap gate doors to open when sufficient fluid build-up exists behind the doors to push the doors open. Hinges are mounted at an angle. Features to facilitate fluid drainage despite the flap gate doors being closed are also contemplated.

To provide a portable device capable of capturing a flow of water from a stream, storm drain or runoff channel, on command and send that captured water into a pipe system, while allowing remote adjustment of the capture and flow rates out of the cube device, the stormwater syphon cube includes a rock grate to prevent stormwater borne objects from entering the device, and an exit valve adjustable via cable control, a side extraction valve adjustable via cable control to adjust the water flow into the extraction pipe, and extraction pipe attached to the cube to carry extracted water away to storage. The sealed exit pipe acts as a syphon drawing water out of the cube.

An automated water control device comprises a rotatable housing that can be incrementally positioned to control flow of water over an upper or weir edge of the housing. The device is installed at a control point in an impoundment area, such as a settling pond. The housing is selectively rotated to raise and lower the height of the weir edge to a target gate height. Automatic control is provided for operation of the device by a controller communicating with an actuator. A system of the invention includes one or more water control devices and the controller. A method of the invention includes controlling flow of water from an impounded water source by use of the automated water control device. Manual or semi-automated embodiments are also disclosed.

An air infiltration system for a hydroelectric plant includes a spillway gate and a linearized cone valve coupled to the spillway gate, the linearized cone valve having a pivotable plate assembly. The spillway gate may be a tainter or Stoney gate and the pivotable plate assembly may have a deflection plate. A method of infiltrating air in water released from an impoundment may include: lifting a spillway gate from a resting position proximate a bottom of a spillway; and pivoting a deflection plate coupled to the gate proximate the bottom of the spillway; wherein water flows through an opening disposed between the deflection plate and the gate and is sprayed into an atmosphere to be oxygenated.

This invention reveals a smooth automatic device and method for efficiently flushing sediment from a reservoir. It includes a sediment flushing funnel located at the reservoir dam's bottom, connected to a sediment flushing pipe. This pipe extends from the funnel's bottom through a smooth connecting pipe, horizontally through the dam, and then to the downstream river channel. Inside the funnel, a trigger-control mechanism is installed, linked to a sediment flushing ball valve within the sediment flushing pipe. The invention operates by automatically opening the ball valve when sediment accumulation in the funnel hits a preset threshold. The sediment is then released into the downstream river channel via the smooth connecting pipe and flushing pipe, driven by gravity. This system offers an effective solution for automatic reservoir sediment flushing, boasting high efficiency, energy conservation, and water resource savings.
