[QUOTE="20x, post: 670332, member: 2569"] once material enters a sluice it all travels at the same velocity depending on its mass and specific gravity. A sluice would have to be very long with scouring zones to create abrasions once suspended and travelling in the same direction. Eg.. A clay bottom of a creek needs 3 meters of velocity per second to even dislodged a single particle.. [/QUOTE]
