... A structure across a river or estuary, built in order to restrain or use water. Brichieri-Columbi and Bradnock (2003) Geog. J. 169, 1 discuss the development of a barrage for the Ganges–Brahmaputra–Meghna waters: which ‘would cause negligible population displacement, and making maximum use of existing river channels would minimize the environmental impacts associated with large canal or dam...

...a barrage required high level co-ordination by the newly created artillery staffs, but its control was most effective when delegated to the lower level commanders being supported. Early barrages often failed when their rigid, pre-planned timetables were overtaken by the unforeseen. If troops were held up by the enemy, the barrage would move on regardless, leaving them exposed; and rapid success often went unexploited because they could not advance through their own slower moving barrage. The ideal was to achieve tactical control over a flexible barrage, but...

...barrage A dam or barrier built across a tidal channel to allow a power-generating plant to operate. The siting of the barrage requires there to be a tidal range in excess of 5 m and a large water body open to the sea, with a narrow entrance. One barrage and generating plant in operation since 1960 is on the Rance estuary in Brittany, France. It generates electricity by the use of two-way turbines, as water flows in and out of the estuary through the barrage. The Severn estuary and Morecambe Bay are potential sites for tidal barrages in the British...

...barrage A 240 MW tidal barrage built across the Rance Estuary at St Malo in Brittany in France. Constructed between 1961 and 1967, it is 740 m long, carrying a road across the estuary, and incorporating a ship lock.The barrage was originally designed to operate with 24 reversible pump turbines allowing for two-way operation, and pumped storage giving almost uniform power operation throughout the day. However, technical problems meant that it is not used in two-way operation. Each turbine has a capacity of 10 MW, operating in a tidal range of up to 12 m,...
