Reference no: EM13550396

The initial piezometric head in a confined aquifer has a thickness of 11.6 m is 85.7 m above sea level. A well with a radius of 0.5 m pumps at a constant rate of 1240 m3/day. After the cone of depression has achieved equilibrium, the piezometric heads at two observation wells 40 and 95 m from the pumping well are measured as 78.9 and 83.4 above sea level, respectively. Also, the piezometric head in the pumping well during equilibrium remains at 46.6 m.
