A concrete dam retains water to a height of 9 m. It has rows of sheet piling at both heel and toe which extend half way down to an impervious stratum. From a flow net sketched on a transformed section, it is found that there are four flow channels and sixteen head drops. The average horizontal and vertical permeabilities of the soil are 6 × 10^–3 mm/s and 2 × 10^–3 mm/s, respectively. What is the seepage in cubic meter per day, if the length of the dam is 150 meters?
