The energy can be dissipated by addressing one or more parts of a spillway's design. [24] Steps. First, on the spillway surface itself by a series of steps along the spillway (see stepped spillway). [5] Flip bucket. Second, at the base of a spillway, a flip bucket can create a hydraulic jump and deflect water upwards. Ski jump
However, a siphon spillway operates as an actual siphon if it raises the flow higher than the surface of the source reservoir, as sometimes is the case when used in irrigation. [35] [21] In operation, a siphon spillway is considered to be "pipe flow" or "closed-duct flow". [36]
Siphon tubes are a basic implement used in irrigation to transfer water over a barrier (such as the bank of a raised irrigation canal), using the siphon principle. At the simplest they consist of a pipe with no working parts. To work they rely on the water level in the canal being at a higher level than the water level in the field being irrigated.

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 chamber is somewhat wider than the pipe, and narrows to approximately the pipe diameter at both ends. One end attaches to the pipe, the other end is open to the liquid. Within the chamber is a sphere, denser than the liquid to be pumped, small enough to move freely within the chamber but large enough to not be able to leave the chamber.
The spillway is designed and constructed to pass flows of three times the maximum recorded flow of the river at this site. [ 2 ] Lake Livingston has a surface area of 83,000 acres (360 km 2 ) and impounds 1,750,000 acre-feet (2.16 km 3 ) of water at its normal pool elevation of 131 feet (40 m) above mean sea level.
