Semi-analytical solution for flow in a leaky unconfined aquifer toward a partially penetrating pumping well
r a 200 .029 : +1 208 cgiss.bo Summary A semi-analytical solution is presented for the problem of flow in a system consisting of unconfined and confined aquifers, separated by an aquitard. The unconfined aquifer is pumped continuously at a constant rate from a well of infinitesimal radius that partially penetrates its saturated thickness. The solution is termed semi-analytical because the exact...
متن کاملNon-Darcian flow toward a larger-diameter partially penetrating well in a confined aquifer
In this study, non-Darcian flow to a largerdiameter partially penetrating well in a confined aquifer was investigated. The flow in the horizontal direction was assumed to be non-Darcian and described by the Izbash equation, and the flow in the vertical direction was assumed to be Darcian. A linearization procedure was used to approximate the nonlinear governing equation. The Laplace transform a...
متن کاملA semi-analytical solution for transient streaming potentialsassociated with confined aquifer pumping tests
We present a semi-analytical solution for the transient streaming potential response of a confined aquifer to pumping at a constant rate through a fully-penetrating line sink. Confined aquifer flow is assumed to occur without fluid leakage from the confining units and is thus described by the solution of Theis (1935). The confining units, which are typically more electrically conductive than th...
متن کاملA Comprehensive Solution for Partially Penetrating Wells with Various Reservoir Structures
This paper presents analytical solutions and simulations for pressure transient behavior of the partially penetrating wells (PPWs). The Newman’s product method was adopted to develop the basic instantaneous source functions which characterize the response of PPWs. These results were obtained based on the solution of fully penetrating wells (FPWs) and they were presented in Laplace domain. Furth...
متن کاملFlowing partially penetrating well: solution to a mixed-type boundary value problem
A new semi-analytic solution to the mixed-type boundary value problem for a ̄owing partially penetrating well with in®nitesimal skin situated in an anisotropic aquifer is developed. The solution is suited to aquifers having a semi-in®nite vertical extent or to packer tests with aquifer horizontal boundaries far enough from the tested area. The problem reduces to a system of dual integral equati...
