Question: A concrete dam rests on an alluvial solid foundation as shown in the scale drawing of Figure P7.8.4. Estimate the seepage rate (in m3/ day)

A concrete dam rests on an alluvial solid foundation as shown in the scale drawing of Figure
P7.8.4. Estimate the seepage rate (in m3/ day) for the 100-m-long dam if the permeability is 4 .45 X 10-7 m/sec and the upstream water depth is 20 m. Also estimate the energy head (using) the dam bottom as the datum) and the seepage velocity immediately below the middle of the dam. The soil porosity is 0.45.
