ABSTRACT:
A method for quantitatively measuring the characteristic physical parameters of a porous medium, such as an aquifer that is initially recharged at a recharge rate and subsequently discharged at a discharge rate by a pumped fluid utilizing a single well into which a tracer is injected during recharge, and at which the tracer is subsequently detected during discharge. A measurement of the elapsed time, together with a formula based on a convective physical model relating the characteristic parameters to the time measurements is provided.
