Riffles and Sluice Boxes - How do they work?

The material that is flowing is in a liquid state. This causes the heavies to be at the very bottom of the flow. As the flow passes over a riffle, the heavies will fall to the bottom behind a riffle. Second, the riffles are spaced a couple of inches apart, and act as a series of small dams, stopping the creep of the heavy material down the sluice.
