A concrete dam is 32m long from the upstream side to the downstream end. The dam is situated on an 18 m thick stratum of soil that has a coefficient of permeability equal to 0.5 m per day. Firm, hard clay and rock lie underlie the described soil stratum. The base of the dam is installed at a level 2 m below the natural soil surface. Required:
Draw the flownet for seepage occurring beneath the dam, and compute seepage in cubic meter per day per meter of dam width (perpendicular to the paper) for the conditions where the reservoir water against the upstream face of the dam is 20m above the soil surface and water level at the downstream end is at 2m above the soil surface.
