HYDRAULICS OF ONE-DIMENSIONAL AND 2-DIMENSIONAL FLOW-FIELDS IN AQUIFERS

New solutions in the Laplace and time domains are developed that descr ibe the transient response of a leaky aquifer to constant and transien t discharge into a fully or partially penetrating sink with storage. A parameter estimation procedure based on the Newton-Raphson algorithm is found to be robust in a synthetic example involving a pumping test of a large-diameter well situated in a leaky strip aquifer. The analyt ical solutions presented may find applications in describing water mov ement in strip aquifers, in aquifers discharging into channels or stre ams, or in thin laboratory tanks.
