In order to meet the objective of providing a device (10) and a method for a sediment transfer in waters (80, 81, 90) that works efficiently, a device (10) comprising at least one suction line (12) and at least one receiving means (16) for receiving sediment (70), and furthermore, having at least one pressure line (14) for transferring the received sediment (70) is proposed. Following the at least one receiving means (16), at least one pump device (18) and at least one measuring device (20) for determining a sediment concentration of the received sediment (70) are arranged. The device (10) further comprises a control unit (22) having a first interface (25) for inputting target values (24) and a second interface (26) for the at least one measuring device (20), and determines a sediment concentration in the at least one suction line (12) and/or in the at least one pressure line (14). Depending on the sediment concentration, a power of the pumping device (18) is adjustable.

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.

A transportable wave suppressor and sediment collection system for suppressing wave action along the shore of a body of water, which includes a plurality of interconnected sections, each section including a base, a forward wall, and a rear wall, and having a plurality of flow pipes extending from the forward wall to the rear wall, and further including a plurality of shelves on the forward wall for dispersing wave energy, while redirecting and using the wave energy to allow water and sediment to flow into the flow pipes and for collecting sediment that is not carried into the flow pipes and settles on the shelves for being contacted by a following wave to carry the sediment into the flow pipes. In some deeper water embodiments, the sections may include a base portion, a top portion and one or more spacer portions to enable raising or changing the height of the system.

A structure for restraining debris in a stream, including lateral walls, which delimit between them a flow section in a bed of the stream. This flow section includes an upper portion that includes set between the lateral walls, a structure for retaining material arriving from upstream, and a lower portion that identifies an opening for outflow.

A system for excavating sediment deposits from water storage reservoirs that equalizes the mass flow of sediment entering the reservoir with the sediment mass in the combined discharge from a dredge and the reservoir outlet system to the downstream water course. One or more remote instrument stations located on the inflow streams to the reservoir collect data that is used by the dredge control system to adjust the mass flow output from the dredge using data collected from the remote reservoir outlet instrumentation located downstream of the reservoir.

A sediment control system for a contaminated source, comprising an intake system for reversibly diverting flow from the contaminated source to a pipeline extending from the intake system to a plurality of spaced discharge outlets in a low turbulence zone within a water body to minimize mixing of the contaminated source flow with the water body. The source may be a stream, an industrial discharge, a construction site siltation settlement pond, a community storm drain, or a mine tailings source, The water body may be a lake, an ocean, a settlement pond, or a water reservoir.

The present disclosure relates to a method for separation of solid particles from a waterbody. Preferably, the present disclosure relates to a method, wherein a combination of chemicals including coagulant(s) and flocculant(s) are employed for said separation of solid particles, wherein suitable examples of solid particles are living organisms and non-living matter, wherein living organisms include autotrophs such as phototrophs, which are either microscopic or macroscopic in nature (algae). The disclosure thus particularly relates to method of chemical coagulation and flocculation for separating solid particles, preferably either algae or bacteria or both from a waterbody. The present disclosure also provides for an alternate method, wherein the aforesaid method of coagulation and flocculation is combined with electro-coagulation and/or pH modulation strategies for separation of said solid particles in any sequence.

A mining method from the use of a Sediment Trap. And a set of Sediment Traps of Different design that by their usage cause an inducement; in the atmosphere of the natural Environment and the hydrosphere of the natural Environment and a part of the lithosphere connected to the hydrosphere of the natural Environment.

A method of improving surf conditions above a seabed is provided. The seabed is at least partly formed of unrestrained sediment. The method includes moving some of the sediment to form a formation of unrestrained sediment. A grooming device is provided for improving surf conditions above a seabed. The device is movable in a direction of travel along the seabed and includes an outlet and an arrangement. The outlet is for directing, in a direction transverse to the direction of travel, a stream of water to move some of the sediment. The arrangement is for engaging the seabed to resist force resultant from the directing the stream of water.
