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 dredging tube system includes a tube unit and a plurality of spaced-apart sediment-trapping units. The tube unit includes a tube structure that has an inner surrounding surface surrounding a longitudinal axis. The sediment-trapping units are mounted fixedly on the inner surrounding surface and are arranged along the longitudinal axis. Each of the sediment-trapping units includes a plurality of sediment-trapping members that cooperatively form an annular ring structure. Each of the sediment-trapping members has an abutment portion that has a curved outer surface entirely abutting against the inner surrounding surface of the tube structure, and a projecting portion that extends radially and inwardly from the abutment portion.

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.

The present invention relates to apparatuses, methods, and systems for removing sediment from waterway bottoms and pumping the sediment through pipelines. More particularly, the present invention relates to apparatuses, methods, and systems for sediment control and altering the average effective depth in a section of rivers, streams and channels for maintaining the navigability of waterways and coastal restoration. The apparatus and method of the present invention including a means for preventing and removing blockages of water flow in the pipelines.

A composite silt fence configured for capturing pollutants in one embodiment comprises a silt fence fabric including i) a polymeric geotextile fabric particulate filtering layer defining the hydraulic flow capacity for the silt fence, ii) a pollutant capturing layer coupled to the polymeric geotextile fabric particulate filtering layer and configured to capture some select pollutants in water from flow that has passed through the polymeric geotextile fabric particulate filtering layer, and iii) a backing layer coupled to the pollutant capturing layer; and a plurality of stakes secured to the silt fence fabric at spaced locations. The silt fence fabric yields higher hydraulic flow than existing fence constructions with greater sediment retention and pollutant containment features.

The invention relates to a dredging method for dredging a navigation channel for guaranteeing a nautical depth of a navigation channel. The method comprises performing agitation for mobilizing sediment and displacing the mobilized sediment to a collector which is embedded in the bottom of the navigation channel, the collector being a trench in the navigation channel wherein the trench has, when not being filled with sediment, a bottom level positioned substantially deeper than the nautical depth of the navigation channel. The method also comprises, in a step different from said performing agitation dredging, after solidification of the sediment collected in the collector, removing the solidified sediment from the collector so that the collector again has a bottom level positioned substantially deeper than the nautical depth of the navigation channel.

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 reservoir dredging assembly includes a dredging tube and at least one dredging device adapted to be installed to at least one secondary reservoir. The at least one dredging device includes a linking tube, an extending tube, a water gate, and a control unit. The linking tube is connected to the dredging tube for water in a primary reservoir, together with sediments deposited therein, to flow through. The extending tube has a top cutlet adapted to be located lower than the maximum water level of the primary reservoir. The water gate is mounted in the linking tube at a position downstream of the extending tube. The control unit is convertible between a first state for closing the water gate and a second state for opening the water gate.

A system for aeration and separation of contaminant from flowing water (10) is disclose wherein a contaminated water travel through up and down flooring (6) and diverted its path frequently by the means of baffle (5) to aerate and increase travel distance in particular channel (1). The sink (2) between last baffle and partition wall (3) collect contaminant and sliding mesh(4) above wall(3) collect the plastic, metallic, paper and weed. Water plants (8) in H block baffle (5) groove with pebbles & soil(9) removes toxic gases in flowing water(7)
