A weir has a solid horizontal floor length of 40 m with two lines of cutoff 5 m depth below the river bed at its two ends. The floor thickness ism at the upstream end and 2 m at the downstream end with its upper level being in flush with the river bed. For an effective head of 4 m over the weir, calculate the uplift pressure at the points C and E and at D and D. And also exit gradient. U/S 5m C1 DI 4m 1m 40 m 2011 D/S Eq 5m D2
