IMPROVED APPARATUS FOR IMPEDING FINE SEDIMENT DEPOSITION IN HARBORS AND NAVIGATIONAL CHANNELS ABSTRACT OF THE DISCLOSURE 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.
