Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams , to adjust flow rates in sluices and canals , or they may be designed to stop water flow entirely as part of a levee or storm surge system.
This gate type was primarily used to purposely inundate certain regions, for instance in the case of the Hollandic Water Line. Nowadays this type of gate can still be found in a few places, for example in Gouda. A fan gate has a separate chamber that can be filled with water and is separated on the high-water-level side of the sluice by a large ...
The spillway is a massive concrete chute, 487 feet (148 m) long and 375 feet (114 m) wide, controlled by three 110-foot (34 m)-wide drum gates each weighing 500 US tons (454 t). When the reservoir is full, the gates cannot entirely prevent leakage but can raise the water level up to 28 feet (8.5 m) above the spillway crest. [45]

If inflow to the reservoir exceeds the gate's capacity, an artificial channel called an auxiliary or emergency spillway will convey water. Often, that is intentionally blocked by a fuse plug . If present, the fuse plug is designed to wash out in case of a large flood greater than the discharge capacity of the spillway gates.
Gate valves may have flanged ends drilled according to pipeline-compatible flange dimensional standards. Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. All-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber ...
