This paper presents a functional formulation of the groundwater flow inverse problem that is
sufficiently general to accommodate most commonly used inverse algorithms. Unknown …

The potential for human activities to adversely affect the environment has become of
increasing concern during the past two decades. Concomitantly, the transport and fate of …

Engineers and applied geophysicists routinely encounter interpolation and estimation
problems when analysing data from field observations. Introduction to Geostatistics presents …

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 …

Stochastic Subsurface Hydrogeology is the study of subsurface, geological heterogeneity,
and its effects on flow and transport process, using probabilistic and geostatistical concepts …

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 …

In this study, we attempt to obtain higher-order solutions of the means and (co) variances of
hydraulic head for saturated flow in randomly heterogeneous porous media on the basis of …

A three‐dimensional solute transport model has been developed to study detailed
contaminant movements through large heterogeneous flow systems in porous media. The …

Formation properties are one of the key factors in numerical modeling of flow and transport
in geologic formations in spite of the fact that they may not be completely characterized. The …

This paper is the first in a four‐part series that describes the application of decision analysis
to engineering design for projects in which the hydrogeological environment plays an …
