Abstract
By using advantages of a semi-analytical approach and Laplace transform technique, a Laplace Transform Finite Layer (LTFL) method is presented for the problem of unsteady flow in leaky confined aquifer systems. The finite layer formulation for drawdown response is developed in the Laplace space. Based on the solution in Laplace space, the groundwater drawdown at a given time and an arbitrary point is obtained by using numerical inversion of Durbin algorithm. The validity of the LTFL scheme is verified based on the existing analytical solution and finite difference method, and the applicability for groundwater flow in modeling flow to partially penetrating wells (PPWs) in the anisotropic leaky confined aquifers is demonstrated.
