At each end of the spectrum, sluicing is the key to recovering the gold in some form. Sluices depend on mats to provide places for the fine gold particles to settle as the water washes the lighter materials away. A constant challenge is to find the best sluice mat for fine gold. Sluice mats come in a variety of styles, types, and materials.

Sluice gates are commonly used water management structures; they are able to deliver flow among both major and minor channels. When used for these operations, they are sometimes referred to as intake structures. These structures can be employed at the dam crest for controlling downstream flow. Irrespective of their simple structures, the …

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)
