What Is a Sluice Gate?
A sluice gate is a mechanism used to control water flow. These devices are often used in water treatment plants, mining, dams, rice fields, and cranberry bogs, among other places. The gates are typically made of wood or metal, and often slide vertically on a frame to open or close, allowing water to flow out of a space or to be contained in it. For this reason, they are also known as a sluice gate valve. Sluice gate design is not only limited to a vertical sliding system, however. One kind of sluice gate acts like a flap and is moved by water pressure being greater on one side than the other. Others are even cylindrical in nature.
