Abrégé

There is provided a material transfer system comprising a first reciprocating conveyor which selectively moves material towards a first location, and a second reciprocating conveyor which overlaps with the first reciprocating conveyor, with the second reciprocating conveyor selectively moving material from the first location towards a second location. There is also provided a material transfer system according to another aspect comprising a conduit in fluid communication with an upstream portion of the body of water, and a reciprocating conveyor configured to convey upstream said material in the body of water towards the conduit. There is further provided a reciprocating conveyor configured to promote movement of the material in a first direction and inhibit movement of the material in a second direction, and a conveyor position adjustment assembly configured to selectively move a first end portion of the conveyor relative to a second end portion of the conveyor.

Abrégé

The present invention relates to a water intake structure according to a first aspect. The structure includes a plurality of elongate members. The elongate members couple together and are trapezoidal in lateral cross-section. There is also provided a water intake structure according to a second aspect. The structure includes a plurality of elongate members. The elongate members couple together. Each said elongate member has first and second exterior surfaces that are planar and a third exterior surface that is outwardly concave.

Abrégé

There is provided a material transfer system including a reciprocating conveyor which selectively moves in a first direction of movement and a second direction of movement opposite the first direction of movement. The conveyor is configured to promote movement of material in the first direction and inhibit movement of material in the second direction. There is further provided a material transfer system comprising a first reciprocating conveyor which selectively moves material towards a first location. The system includes a second reciprocating conveyor which overlaps with the first reciprocating conveyor. The second reciprocating conveyor selectively moves material from the first location towards a second location. There is also provided a material transfer system comprising a passageway having an upstream inlet and a downstream outlet. The passageway may be a conduit, a siphon or chute. The system includes a reciprocating conveyor conveying fluvial material towards the inlet of the passageway.

Abrégé

There is provided a water intake structure. The water intake structure includes a plurality of spaced-apart elongate members. The water intake structure includes a plurality of slots, each extending between adjacent pairs of the elongate members. Each elongate member is shaped to promote a Coanda effect, with portions of water passing thereon being taken in through an adjacent downstream said slot thereby.
