A field test is conducted in a confined aquifer by pumping a constant discharge of 14.9 m3/hr from 20-cm-diameter well. After an approximate steady state is reached, a drawdown of 0.98 m is measured in the pumped well. Also measured are drawdowns of 0.73 m, 0.65 m, 0.60 m, and0.57 m, respectively, at 8.0 m, 30.0 m, 80.0 m, and 132 m from the pumped well. Determine the transmissivity of this aquifer. Also, determine how far away from the well...

In a pumping test of a confined aquifer, the steady state water level in an observation well 10m from the pumping well was 38mOD and was 42 mOD in another observation well 100m from the pumping well. The water levels in both wells were steady at 50mOD before the test began and then water was pumped at a constant rate of 0.005m^3/s from the pumping well. Estimate the aquifer transmissivity. If the aquifer is 15m thick, estimate the hydraulic conductivity...
