Problem #1 Saturated Flow
Water flows through three confined aquifers in series as shown below. For piezometric heads in
the observation wells of 75.3 m and 63.6 m, determine the flowrate per unit width of the
aquifer and the change in piezometric head in each component of the aquifers between the
observation wells.
