Pondage usually refers to the comparably small water storage behind the weir of a run-of-the-river hydroelectric power plant. Such a power plant has considerably less storage than the reservoirs of large dams and conventional hydroelectric stations which can store water for long periods such as a dry season or year.
Mettur Dam capacity: 93.4 Tmcft Tmcft , ( Tmc ft ), ( TMC ), ( tmc ) is the abbreviation of thousand million cubic feet (1,000,000,000 = 10 9 = 1 billion ), commonly used in India in reference to volume of water in a reservoir [ 1 ] or river flow.
For self-similar time series, H is directly related to fractal dimension, D, where 1 < D < 2, such that D = 2 - H.The values of the Hurst exponent vary between 0 and 1, with higher values indicating a smoother trend, less volatility, and less roughness.
By damming a river, the head is available to generate power at the face of the dam. A dam may create a reservoir hundreds of kilometres long, but in run-of-the-river the head is usually delivered by a canal, pipe or tunnel constructed upstream of the power house. The cost of upstream construction makes a steep drop desirable, such as falls or ...
During uniform flow, the flow depth is known as normal depth (yn). This depth is analogous to the terminal velocity of an object in free fall, where gravity and frictional forces are in balance (Moglen, 2013). [3] Typically, this depth is calculated using the Manning formula. Gradually varied flow occurs when the change in flow depth per change ...
They can be used to divert, disrupt or completely stop the flow. An example of a hydraulic structure would be a dam, which slows the normal flow rate of the river in order to power turbines. A hydraulic structure can be built in rivers, a sea, or any body of water where there is a need for a change in the natural flow of water. [1]

December 2023) (Learn how and when to remove this message) In hydrology , discharge is the volumetric flow rate (volume per time, in units of m 3 /h or ft 3 /h) of a stream . It equals the product of average flow velocity (with dimension of length per time, in m/h or ft/h) and the cross-sectional area (in m 2 or ft 2 ). [ 1 ]
