seepage is occurring through the sandy layer underneath the concrete dam.Given: upstream water level = 15.8 m; downstream water level = 2.1 m; thickness of the sandy layer = 1.1 m; coefficient of permeability of the sandy layer = 0.0081 cm/s and L = 48 m. Determine: 1.The seepage flowrate per unit length of the wall in m3/hr/m. 2.Quantity of seepage per day if the dam is 400 m long.
