Though popular in the geophysical modeling community, specification of spatially distributed parameters at a scale commensurate with prevailing geological heterogeneity has not been possible in common groundwater modeling practice. The principal reasons for this are (1) the high computational burden of obtaining derivatives necessary for parameter estimation, (2) the memory required to store th...
