An accurate representation of permeability anisotropy is needed to accurately model the rate and direction of groundwater flow. Wavelet analysis can be used to characterize principal directions of permeability anisotropy; however, if the permeability field contains regions with different principal directions, wavelet analysis may only identify the principal direction of the primary region. We present a combined wavelet analysis and filtering method to characterize primary and secondary principal directions of permeability anisotropy.
