Example 2: A flow net is plotted for a homogeneous earthen dam of height 22 m and freeboard 2.0 m. The results obtained are, Number of potential drops = 10 Number of flow channels = 4. The dam has a horizontal filter of 30 m length at the downstream end and the coefficient of permeability of the dam material is 5 x 104 cm/sec. Calculate the discharge per m run of the dam.
