ABSTRACT:
A dredging apparatus has a chamber with a substantially circular cross section. A first inlet and outlet is formed through the chamber with an axis of the inlet and outlet normal to a diameter of the chamber. A suction inlet is formed through the axis of the chamber along the axis of the vortex formed as the fluids leave the inlet and pass to a second outlet formed substantially coaxially with the vortex. Apparatus is provided for supporting the dredging apparatus in a position so that the suction inlet can remove material desired to be dredged.
