Objective Question & Answer

A masonry dam 100 m long and overlying an impervious soil is founded on a soil with anisotropy

in permeability. The upstream water level is 12.5 m and the tail water level is 3.5 m above the

ground level. The vertical permeability of the soil is 1.40 m/day and the horizontal permeability is

9 times as that of the vertical permeability. The flow net drawn on a transformed section yields 6

flow channels and 8 equipotential drops. The seepage through the foundation soil, per 'm' length

of the dam is
