WebDec 1, 2024 · Weirs are hydraulic structures used for measuring discharge. The stage-discharge relationship of a inclined non-rectangular weir is theoretically deduced. The stage-discharge relationship is deduced by dimensional analysis and self-similarity theory. The theoretically stage-discharge relationship is tested by experimental data. Abstract WebExample - Discharge Over A Rectangular Weir Problem A weir of 8m long is to be built across a rectangular channel to discharge a flow of 9m3 /s. If the maximum depth of water on the upstream side of weir is to be 2m, what should be the height of the weir ? Adopt C d = 0.62. Given, L = 8 m Q = 9 m 3 /s Depth of water = 2m C d = 0.62
