Chapter 7, Problem 7.22P

Refer to Figure 7.24. The following data were collected during the field permeability measurement of a confined aquifer using a pumping test. Determine the hydraulic conductivity of the permeable layer. Use Eq. (7.49).

Thickness of the aquifer, H = 4.5 m

Piezometric level and radial distance of the first observation well:

h1 = 2.9 m; r1 = 17.8 m

Piezometric level and radial distance of the second observation well:

h2 = 1.8 m; r2 = 8.1 m

Rate of discharge from pumping, q = 0.5 m3/min
