The Highbanker: An Automatic Power Sluice - Owlcation

Mar 01, 2020 · The water surface of a stream is irregular (or riffled) due to irregularities of sedimentary deposits at the bottom. This turbulence is mimicked in the sluice box by strips of wood, plastic, or metal, usually aluminum. They copy the action of naturally riffled water by creating barriers to the flow of water (slowing it down).
