ABSTRACT:
A sediment filtering apparatus and a method for removing sediment from a waterway. One or more collector assemblies are secured to a river bottom and have a leading, ramp surface facing upstream and over which the water flows. As the water/sediment mixture passes the apex of the collector, the trailing edge drops off rapidly thereby reducing the stream velocity and allowing the sediment to settle from the flow. The sediment then collects on the downstream side of the collector and via one or more openings reaches an internal cavity. A suction pipe is placed under negative pressure and draws the water/sediment mixture to a filtering apparatus which then returns filtered water to the waterway. The sediment and debris filtered therefrom is then easily removed.
