An earthdam has a crest width of 15 feet , total height of 40 feet and the inclinations at heel and at toe both at 45 degrees w.r.t. the horizontal. If the coefficient of permeability of the earthdam material is 0.00042 ft/min, determine the seepage rate in cubic feet/day/ft of dam. Height of water at upstream is 30 feet. Use Dupuit's method.
