    摘要： The invention discloses an overshot control gate for use with trapezoidal irrigation channels. A gate has a rigid rectangular section adapted to, in use, be pivotally mounted to a base of a trapezoidal irrigation channel. A pair of triangular sections are pivotally mounted on opposite sides of the rigid rectangular section. Each of the triangular sections are divided into first and second triangular sections with a common apex at the base of the trapezoidal irrigation channel. Each of the first triangular sections are rigid and adapted to, in use, be pivotally mounted to opposite side walls of the trapezoidal irrigation channel. Each of the second triangular sections including the pivotal mounting on opposite sides of the rigid rectangular section are formed of a flexible material. Also disclosed is a pipe flow meter and a duckbill valve.

    摘要： A system for recirculating lock water includes a sealable storage area located near a lock for receiving water from the lock. The storage area is large enough to house the lock water with excess space between a maximum water level and the ceiling. The system also includes at least one compressor connected to the storage area to create a vacuum to withdraw the water from the lock into the storage area.

    摘要： A screen intake apparatus has a concrete platform resting on a water source floor. A screen intake anchors on the platform and forms a half cylinder thereon. A barrier at one end of the platform in divides the flow of water. The screen intake has a half-cylindrical body and half-cylindrical screens. Transition walls in the screen intake divide the body's hollow and the screens' interiors, and at least one flow modifier communicates the interior with the hollow. These flow modifiers also form a half cylinder with the platform. A manifold in the screens receives a supply of air to clear debris. Forming a half-cylinder, the screen intake on the platform can have a much lower profile for the water source than the normal cylindrical screens, which require half of its diameter in clearance above and below.

    摘要： A method of removing solid matter from liquid using two or more sets of screening devices installed in series. Each set of screening devices consists of one or more identical or nearly identical screening devices. Each downstream set of screening devices has smaller openings than the preceding upstream set of screening devices. Solid matter collected by the screening devices is automatically discharged onto two or more conveyor systems that deposit the material onto one or more central collection areas for final removal and disposal. The present invention uses screening devices in a special configuration to achieve enhanced removal of solid matter from liquid (i.e. a series installation with screen opening size decreasing in a downstream direction).

    摘要： A self-cleaning screen and method for screening water for hydraulic turbine intake diversions is disclosed. A check dam is established across a river on the downstream side of a side channel weir which is at a lower elevation than the dam. A fish transport trough is laterally spaced from the weir at a lower elevation and has an inlet upstream of the weir and an outlet downstream of the dam. A screen having a concave profile is connected between the weir and the trough to remove debris from water flowing over the weir. Water flowing through the screen enters a separate channel under the screen for diversion to a hydraulic turbine inlet water application. Intermittent surges of water over the weir flush debris off the edge of the screen into the trough to clean the screen.
