Q.3 Calculate the seepage through an earth dam (Shown in figure) resting on an impervious foundation. The relevant data are as follows: (20) Height of the dam= 60.0 m Upstream slope = 2.75: 1 (H:V) Downstream slope = 2.50: 1 (H:V) Freeboard = 2.5 m Crest width = 8.0 m Length of drainage blanket= 120.0 m Coefficient of permeability of the embankment material : In x-direction = 4 x 10-7 m/s In y-direction = 1 x 10-7 m/s +8 2.75 2.5 1 60 120 Note: All dimensions in above figure are in meter.
