Abstract

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.
