Abstract	An inverse boundary element method is developed to characterise the components of the hydraulic conductivity tensor ${\mathbf K}$ of anisotropic materials. Surface measurements at exposed boundaries serve as additional input to a Genetic Algorithm (GA) using a modified least squares functional that minimises the difference between observed and BEM-predicted boundary pressure and/or hydraulic flux measurements under current hydraulic conductivity tensor component estimates.
