There are a number of design factors to consider such as riffle size, geometry, spacing, water pressure, aperture size and spacing, etc. The primary advantage of a hydraulic riffle is that it "dilates" or fluidizes the sluice bed which could allow heavies to penetrate deeper and have a better chance of being retained. It will also help keep the sluice from becoming impacted or "plugged up ...
But over time this lighter material will slowly migrate down the box and finally exit out the end of the sluice, washing out from behind one riffle, and then the next. During the flow, as heavier material comes through, it also settles behind the riffles, and as lighter material migrates, the heavier stuff settles slowly to the bottom.

· Sluice boxes have been used by gold prospectors for years. The bottom of a sluice box is covered with socalled riffles. Water flows through these riffles, and any heavy material, including gold, falls to the bottom of the box while the water and any lighter materials, including sand, is washed away.

Riffle Shapes And Design Sloped Flat Bar Riffles.
