barrages. Historically, Pakistan has been designing and constructing weirs and barrages, which has led to the state-of-the-art present-day knowledge. Even before the creation of the country, the areas now included in Pakistan were under-going developments to build some gigantic and remarkable engineering works. In 1871, the weir across River Ravi was built at the head of Bari Doab canal in
Abstract. Barrages are hydraulic structures constructed across rivers to divert flow into irrigation canals or power generation channels. The most of these structures are founded on permeable foundation.

A barrage is a weir that has adjustable gates installed over top of it, to allow different water surface heights at different times. The water level is adjusted by operating the adjustable gates. The water level is adjusted by operating the adjustable gates.
The different water levels are increased with respect to time then weir is raised and barrages are constructed. Gates: are constructed to increase the water level. When it is required to increase the water level the gates are closed and vice versa.

Barrages and weirs A barrage is typically an active structure for diverting the course of a river (for irrigation, hydropower or to reclaim land), to control the downstream river height (for flood protection or navigation), to better manage supply and salinity (for drinking water supply, agriculture or industry) or to contain a lagoon (for tidal energy).

For a weir to be fully contracted, (B-b) must be greater than 4h max, where h max is the maximum expected head on the weir (USBR, 1997). A partially contracted weir has B-b between 0 and 4h max . Weir contractions cause the water flow lines to converge through the notch.

RIVER STRUCTURAL WORKS AND OPERATION Diversion Works

A weir is a concrete or masonry structure which is constructed across the open channel (such as a river) to change its water flow characteristics. Weirs are constructed as an obstruction to flow of water. These are commonly used to measure the volumetric rate of water flow, prevent flooding and make

After the establishment of the River Murray Commission in 1917, regulating structures including weirs and locks were constructed along the River Murray. Weir & Lock 1 at Blanchetown was the first to be completed in 1922. Other weirs and locks were progressively constructed, with Yarrawonga Weir being the last to be completed in 1939 and the
Diversion Head Works: Weir and Barrage The works, which are constructed at the head of the canal, in order to divert the river water towards the canal, so as to ensure a regulated continuous supply of silt-free water with a certain minimum head into the canal, are known as Diversion Head works.

A simplified approach to the design of impounded estuarine tidal power schemes is described, based on the mean tidal amplitude and the surface area of the enclosed basin.
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 only difference between a weir and a barrage is of gates, that is the flow in barrage is regulated by gates and that in weirs, by its crest height. Barrages are costlier than weirs . Weirs and barrages are constructed mostly in plain areas.
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 structural details are worked out.
Design and operation of Locks and Weirs A lock is a simple design; a rectangular chamber of concrete with gates at each end. The locks permit boats to move from one level to another.
