A sluice gate. A sluice (/ s l u s / SLOOS) is a water channel containing a sluice gate, a type of lock to manage the water flow and water level. It can also be an open channel which processes material, such as a river sluice used in gold prospecting or fossicking.
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.
[1] [3] The dam measures 293 feet (89 m) and includes 4 vertical sluice gates. [ 4 ] The lock and dam are used to maintain a 9-foot navigation channel, and for flood control purposes, primarily to limit diversion from the lake during normal periods, and mitigation of backflows into Lake Michigan during large storm events which reverse the ...
A gatehouse, gate house, outlet works or valve house for a dam is a structure housing sluice gates, valves, or pumps (in which case it is more accurately called a pumping station). Many gatehouses are strictly utilitarian, but especially in the nineteenth century, some were very elaborate.
An electric multi-turn actuator on a gate valve. A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.
The controlling works contains eight sluice gates along its piers, each measuring 10 feet (3.0 m) x 10 feet (3.0 m), allowing water from Lake Michigan into the river for navigational and sanitation purposes during normal weather operations, and for allowing water out of the swollen river into the lake during heavy rainfall periods as a measure ...
A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is of Scots origin, and was inherited from the earlier technology of mill ponds and watermills, with penstocks diverting pond waters to drive the mills.
The sluice gates applicable to tidal power are the flap gate, vertical rising gate, radial gate, and rising sector. Only a few such plants exist. The first was the Rance Tidal Power Station , on the Rance river , in France, which has been operating since 1966 and generates 240MW.
