It is now widely recognized that groundwater aquifers exhibit significant three-dimensional, small-scale variability in their hydraulic properties and that this variability controls the migration and dispersion of contaminants at the field scale. Quantitative study of the impact of small-scale variability upon field-scale transport has been a central theme of groundwater research in recent years; this research has been motivated by a host of important questions. How can properties measured on small samples in the laboratory be extrapolated to larger scales? Are fundamental constitutive relations derived from studies at the laboratory scale valid at field scales? How can we quantify the inherent uncertainty in our information on spatially varying soil properties? What is the effect of this uncertainty upon the reliability of model predictions?
