MODELLING THE LOCAL VARIATION OF AQUIFER PARAMETERS WITH THE HELP OF THE ANALYTIC ELEMENT METHOD

Abstract

The Analytic Element Method (AEM) for groundwater flow modelling and also its application possibilities were presented in an earlier volume, [2,3]. The present paper focuses on one certain element of it, the so-called inhomogeneity. The inhomogeneity describes the local variation of aquifer parameters, like its thickness, base elevation or permeability. After a short introduction of the method, the mathematical description and application conditions for the different approaches of inhomogeneities are given in details. Finally, some recommendations are given to help in the decision which approach to use.
