Among the current problems that hydrogeologists face, perhaps there is none as
challenging as the characterization of fractured rock (Faybishenko and Benson 2000). This …

Heterogeneity is the single most salient feature of hydrogeology. An enormous amount of
work has been devoted during the last 30 years to addressing this issue. Our objective is to …

Geostatistics as a subfield of statistics accounts for the spatial correlations encountered in
many applications of, for example, earth sciences. Valuable information can be extracted …

A governing equation of stable random walks is developed in one dimension. This Fokker‐
Planck equation is similar to, and contains as a subset, the second‐order advection …

This monograph presents, for the first time, a unified and comprehensive introduction to
some of the basic transport properties of porous media, such as electrical and hydraulic …

Hydrogeological variables of a groundwater system, for example, the hydraulic head and
contaminant concentration, vary with space and time. The variability is due to spatial …

The concept of scale can be used to quantify characteristic lengths of (a) a natural process
(such as the correlation length of the spatial snow water equivalent (SWE) variability);(b) a …

A large‐scale natural‐gradient tracer test in a highly heterogeneous aquifer at the
Macrodispersion Experiment (MADE) site on the Columbus Air Force Base in Mississippi is …

Over the past two decades there have been repeated calls for the collection of new data for
use in developing hydrological science. The last few years have begun to bear fruit from the …

Geology is ubiquitously heterogeneous, exhibiting both discrete and continuous spatial
variations on a multiplicity of scales. It is therefore natural to expect that hydrogeologic and …
