An apparatus for preventing sedimentation buildup in waterways having a current, the apparatus being submergible at a location proximate the edge of the waterway and adapted to produce a scour pattern of predetermined configuration. The apparatus includes an elongated, substantially vertical tubular member having an inlet assembly connected proximate the upper end of the tubular member; a turbine fan unit mounted interiorly of the inlet assembly for controllably drawing water into the apparatus; and a discharge assembly connected to the tubular member proximate its lower end for directing the flow of water outwardly from the tubular member in generally horizontal direction at an optimum flow rate.

An apparatus for preventing sedimentation build-up in harbor berthing area of the character having wharf fronting the berthing area, comprising a plurality of submergerd, scour units disposed adjacent said wharf in side-by-side relationship, each said scour unit comprising: (a) a vertical tubular member having a vertical axis including an upper end and a lower end; (b) inlet means connected proximate said upper end of said tubular member for directing the flow of water into said tubular member; (c) turbine means mounted interiorly of said inlet means for controllably drawing water into said inlet means, said turbine means including a rotating fan and hydraulic motor means for controllably rotating said fan; (d) discharge means connected proximate the lower end of said tubular member for directing the flow of water outwardly therefrom in a generally horizontal direction to produce a near bottom, scour pattern of a predetermined configuration, said scour units being arranged along said wharf so that said scour patterns produced by said discharge means overlap one another; (e) means for rotating each said discharge means about the vertical axis of each said tubular member, whereby each said discharge means produces a scour pattern spanning about 180 degrees; (f) operating means mounted on said wharf and operably interconnected with each said hydraulic motor means for providing hydraulic fluid for operating each said hydraulic motor means; and (g) means mounted on said wharf for raising and lowering each said tubular member.
