Abstract

1377508 Dredging devices BALLAST-NEDAM GROEP NV 29 Dec 1971 [25 Feb 1971] 60485/71 Heading E1F Ground lying beneath flowing water is dredged by a rolling rotor as it is towed over the ground against the water flow to direct and accelerate some of the water flow adjacent the ground at the ground to cause scouring away of the ground. The rotor together with an associated towing yoke may be of such a construction that controlled variation of the buoyancy thereof may occur.
