What is the purpose of a sluice gate?
What is a sluice gate? The gate that controls a sluice is a valve known as a “sluice gate.” These valves are designed to seal in one direction and commonly are used to control water levels and flow rates in rivers and canals. They also are used in wastewater treatment plants.

What does the word tailrace mean?
Definition of tailrace : a race for conveying water away from a point of industrial application (such as a waterwheel or turbine) after use.
How does a sluice work?
Sluice boxes are designed to mimic this naturally occurring gravity separation. As water carries gold-laden sediment through the box, small obstructions called riffles block the free flow of material. These tiny flow restrictions form low pressure pockets where the gold collects.
What is a sluice robber?
A “sluice-robber” is someone who would then go around stealing the gold from unattended sluices.
What are under sluices?
The under sluices are the openings provided at the base of the weir or barrage. These openings are provided with adjustable gates. Normally, the gates are kept closed. The crest of the under-under sluice portion of the weir is kept at a lower level (1 1.5 m) than the crest of the normal portion of the weir.
What is a tailrace used for?
A tail race channel on a hydroelectric dam. The tail race, containing tail water, is a channel that carries water away from a hydroelectric plant or water wheel. The water in this channel has already been used to rotate turbine blades or the water wheel itself.
What is head race and tail race?
The race leading to the water wheel on a wide stream or mill pond is called the head race (or headrace), and the race leading away from the wheel is called the tail race (or tailrace).
