The distance-drawdown method is an equilibrium or steady-state method, thus storage cannot be estimated. 58 pages, Paperback. Published February 11, 2013. WebThe vertical permeability of a confining bed often can be determined from the results of pumping tests by using the nonsteady-state leaky artesian aquifer equation derived by Hantush and Jacob (1955). A time-drawdown type curve method for analyzing pumping test data under nonsteady-state conditions is described in detail.
