ABSTRACT A new and improved dredging method and apparatus including a pump (10, 10a) which forms a vortex pressurized stream of liquid within the pump and directs the stream down the inlet conduit (27) to discharge at the inlet (15) at which the momentum and energy of the traveling stream (30) breaks up the clay gravel or other material being dredged from the bed and swirls the same into a puree of solids and liquid which forms a thick viscous stream (31) which flows into the pump inlet and inlet conduit about the vortex stream. The vortex member runner (35) generates the vortex by being rotated at a high speed; for example, in excess of 1,200 rpm without cavitation. Preferably, the pump (10a) is directly connected to a diesel motor and is driven directly at the speed of the diesel motor without cavitation.
