If you are adding material to a hopper underwater, and then using a ventury system to move that material to the surface to be processed, that is still a suction system. You would have to move the material to the surface by a means that did not include water using any kind of ventury system (suction) in order to not be included as a suction dredge by regulation.

Actually I'm thing of using a hydrolic ram, in the form of a high velocity stream of water, to push material to the surface. No venturi no suction used.
