Venturi is exactly what is used for a dredge. ........

Diggertom said:May be a silly question as dredging is in the name, but what about gravity dredging, where you just lay the hose out in a creek bed and wait for the water to start running? I've seen a couple of videos on youtube and thought it seemed stupid to start with but it did have quite a bit of suction and defiantly moved a lot of material! And given there is no mechanics to it, and from my understanding no hydraulics, but I also don't fully understand the word Hydraulics in this scenario.

If you are caught dredging our waterways, there are hefty fines as well as your gear being confiscated, not only that but you'll be doing a huge injustice to ALL Australian prospectors in general.
