An experiment was conducted to determine the hydraulic conductivity of an artesian (i.e., pressured confined aquifer). The piezometric heads at two points 150 m apart were found to be 60 m and 56 m above a datum (reference level). A tracer injected into the first piezometer was observed after 20 hours in the second well. A test on porosity of a sample of the aquifer shows that α = 24%. a) What are the Darcy velocity (q) and seepage velocity (v) of groundwater flow. b) What is the conductivity of the aquifer?
