What does sluicing mean?
Sluicing is the controlled release or direction of water or another liquid through a sluice, gate, or comparable opening. The term also refers more broadly to the process of washing, sorting, or separating material with flowing water, especially in mining. It can describe deliberate engineering activity, such as directing water into fields or drainage channels, as well as an uncontrolled flow through a breach or open structure. The related noun “sluice” names the gate, channel, or opening itself, whereas “sluicing” emphasizes the movement of liquid or the action performed. Although uncommon in everyday speech, sluicing is well established in technical and historical contexts, particularly in descriptions of flood control, irrigation, hydraulic construction, and placer mining.
To let or direct water or another liquid through a sluice, gate, or similar opening.
"The reservoir began sluicing water into the irrigation canals."
The verb is often transitive when material is being washed or sorted, as in “sluicing gold,” and intransitive when the emphasis is on the flow itself.
The act or process of releasing, directing, or separating material with water flowing through a sluice.
"The constant sluicing of water wore deep channels into the riverbank."
As a noun, it is chiefly used in technical, historical, or mining contexts rather than everyday speech.
Behind the everyday word sluice lies the power of a sudden torrent—and, in placer mining, the prospect of finding gold in the rushing water.

Where does sluicing come from?
The word comes through Middle English forms such as “sluse” and “sluice,” used for a water channel or controlling gate. It belongs to a northern European Germanic word family reflected in Dutch “sluis” and German “Schleuse.” Modern English developed both “sluice” as a noun and “sluice” as a verb, with “sluicing” serving as a gerund and present participle.

How sluicing is actually used
The word is relatively uncommon in general conversation but is used in engineering, agriculture, drainage, and mining contexts. As a gerund or present participle, it may describe either an intentional flow or a flow occurring through an open or damaged channel.
Easily confused with sluicing
A sluice is the gate, channel, or opening that controls a flow, whereas sluicing is the act of allowing or directing liquid through it.
