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 river in order to power turbines.

Turbine characteristics are normally established on the basis of tests carried out in hydraulic laboratories on homologous models of the machine and of certain associated water passages, be it distributor pipework and nozzles in the case of a Pelton wheel, or a portion of the inlet pipe, the spiral casing and the draft tube in the case of a reaction :// How to Design Barrage. The Barrage and the Head Regulators of feeder channels and appurtenant structures will be designed on the basis of standard design criteria established for other barrages and allied structures, already constructed on the Indus River and its tributaries. The design criteria, including formulae, coefficients and constants will be used in all hydraulic designs as ://    Coefficient of contraction is the ratio of (A) Actual velocity of jet at vena contracta to the theoretical velocity (B) Loss of head in the orifice to the head of water available at the exit of the orifice (C) Loss of head in the orifice to the head of water available at the exit of the orifice (D) Area of jet at vena-contracta to the area of orifice   Hydraulic structures for flow diversion and storage: Design of the Main Diversion Structure of a Barrage: PDF: kb: Hydraulic structures for flow diversion and storage: Design of Barrage Appurtenant Structures and Rules for Barrage Operation: PDF: kb: Hydraulic structures for flow diversion and storage: Structures for Water Storage?

  The barrage method of extracting tidal energy involves building a barrage across a bay or river that is subject to tidal flow. Turbines installed in the barrage wall generate power as water flows in and out of the estuary basin, bay, or river. These systems are similar to a hydro dam that produces Static Head or pressure head (a height of water The barrage is about 2, m long and started its operation on Ap (Salman & Uprety, ). The purpose of the construction of the barrage was to div cusec (equivalent to 1, m 3 /s) water from the Ganges River to the moribund Hooghly River (a distributary of the Ganges) for maintaining the navigability of the Kolkata   design of barrage the design of any hydraulic structure comprises of two steps: • hydraulic design, to fix the overall dimensions and profiles of the structure (dimensions are usually fixed by empirical formulae) • structural design, where the various sections are analysed for stresses under different loads and reinforcement or other   Endnotes [1] Arunabh Saikia, “Manipur asks for a review after the ruling BJP wants Loktak hydroelectricity project broken down”, Scroll, Aug [2] The Imphal Free Press, “Consult indigenous peoples before commissioning mega projects: AHRC”, Centre for Research and Advocacy Manipur, Septem [3] R.
