Regular maintenance of wire rope is considered the key to ensuring the safe operation of a sluice gate. Along these lines, in this work, a six-wheeled wire rope climbing robot was proposed, which can carry cleaning and maintenance tools for online cleaning and safety inspection of the sluice wire rope, without its disassembly. The developed …

Many people design elaborate sluices that are way longer than necessary. Width is commonly about a foot or two wide, and the height is approximately 6 to 12 inches. Since a sluice should ideally be situated in a shallow section of stream, the depth of the box does not need to be much, just enough to capture water to flow over the riffles and ...

A sluice box should be set with a 4-8 degree angle. Another rule of thumb is that the sluice should be angled to drop roughly 2 inches per foot of length. The exact angle depends on the size and weight of the material, the riffle design, and the speed of the current.

Sluice gate flow metering is often used to measure flow rate in open channels. Sluice gates are also often used to modulate flow. The sluice gate flow rate measurement is based on the Bernoulli Equation and can be expressed as:. 1/2 ρ v 1 2 + ρ g h 1 = 1/2 ρ v 2 2 + ρ g h 2 (1). where. h = elevation height (m)
