The Hantush-Bierschenk method does not provide T or S, but does provide well loss coefficients and an equation describing well drawdown with pumping rate as the independent variable. The Eden-Hazel method works with increasing or decreasing discharge rates as well as recovery data. Show here is an arithmetic time-drawdown graph where the initial step was pumped at a higher rate than subsequent steps. Even this data can provide reliable estimates of aquifer transmissivity with StepMaster. Shown here is the above data analyzed with the Eden-Hazel method.
Show here is a semi-logarithmic graph of the above recovery data.
