Question

For the Barrage shown in the figure below, Pond level - 24m 12m DS 21 m 10m 20m 19m EG , 17 m 1.11 15 Cs 14 D EC 0.5m D.10 m 14.5m 5m D/29m 24.500 44m 0.5 m
Using all three theories; (a). Draw H.G.L. (hydraulic gradient line) for static head condition (b). Check the safety against piping failure; assume the bed soil of the river is coarse sand. (c). Find the uplift pressure head at point A & B.
