Question

A long-term pumping test was conducted to determine the hydraulic conductivity of a 82 mthick confined aquifer. The non-pumping piezommetric surface was 109.5 m above the confinedlayer. The pumping rate was 0.03 m'/s. The steady-state drawdown at an observation well 45 maway from the pumping well was 3.6 m. The drawdown at an observation well 65 m away fromthe pumping well was 1.4 m.

(a) Determine the hydraulic conductivity of the confined aquifer.

(b) Determine the influence radius of this pumping well system.

Answer 1

We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.
