Abstract

A geostatisticai formulation, based on Stochastic Indirect Bound- ary Element Method (SIBEM). is obtained for the determination of hydraulic conductivities in aquifers. Using a perturbation technique the governing equations are reduced to an asymptotic series of partial differential equations (PDEs). The ensuing perturbed PDEs are con- verted into boundary integral relations which can be manipulated to provide suitable expressions for the geostatistics of aquifers. INTRODUCTION The integrity and usefulness of hydrogeological models are closely linked to the accurate determination of key parameters that affect the tran
