Abstract
An inverse boundary element method is developed to characterise the compone nts of the hydraulic conductivity tensor K of anisotropic materials. Surfac e measurements at exposed boundaries serve as additional input to a Genetic Algorithm (GA) using a modified least squares functional that minimises th e difference between observed and BEM-predicted boundary pressure and/or hy draulic flux measurements under current hydraulic conductivity tensor compo nent estimates.
