An apparatus for mounting adjacent the bottom of a waterway having a current for impeding the deposition of suspended sediments upon the bottom of the waterway. A buoyant wing member having leading and trailing edges with substantially flat top and bottom surfaces includes a flap member spanning the wing member and extends at a predetermined upward angle away from the top surface towards the leading edge. The apparatus is mounted with the flap member facing the bottom of the waterway wherein the fluid in the wake is accelerated upwards away from the waterway bottom so as to resuspend fine sediments. When the wing member is mounted with the flap member directed away from the waterway bottom the wake is directed downwards against the bottom causing scouring of the waterway bottom.

A buoyant high aspect ratio delta wing having an inverted airfoil shape for producing a downward lift force is anchored at a negative angle of attack adjacent the bottom of a waterway having a current. The net vertical deflection and turbulent trailing wake generated as the water flows past the wing prevents sediments from depositing on the bottom of the waterway for a predetermined distance downstream of the wing. Cascading arrays of such wings may be anchored in succession along the waterway to resuspend sediments and thereby maintain sufficient water depth for navigation while avoiding the cost and environmental drawbacks of dredging.

The scour jet array system includes a pump, both fresh water and surface er intakes, an automatic water mixing valve, a chemical buffer injector, a water heater, a series of scour jets with control valves, and a central control system. The control system senses the beginning of ebb tide for starting an initial scour jet, and as each jet scours the freshly deposited mud from the area, temperature, salinity and pH of the surface suction intake water are measured to determine the amount of fresh water injection, chemical buffer injection, water heating and duty cycle time in order to minimize the energy required to scour the sediments from the area.
