Riffles and Sluice Boxes
The reason that riffles work is two fold. First, there is an eddy created behind each riffle, causing a temporary lull in the water flow. 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.
