The dam shown has a base of which 2m below the ground surface. The pressure distribution diagram at the base of the dam can be obtained from the equipotential lines as follows: k=4.5 m/day. if H=6m determine the seepage through the foundation.
A concrete dam is 30 m long from upstream side to downstream end. The dam is situated on a 15-m-thick stratum of soil that has a coefficient of permeability equal to 0.5 m per day.
