A sluice gate is a hydraulic control device designed to regulate water flow in open channels, canals, rivers, reservoirs, and engineered systems such as drainage and sewer networks. Operating as a vertically sliding barrier, it can be raised or lowered to allow, restrict, or completely stop water flow, enabling precise control of water movement. As a critical element of water management infrastructure, sluice gates are widely used in flood control systems, water treatment facilities, irrigation networks, and wastewater treatment plants.
