Groundwater models are essential for understanding aquifer systems behavior and effective
water resources spatio-temporal distributions, yet they are often hindered by challenges …

Non‐Fickian (or anomalous) transport of contaminants has been observed at field and
laboratory scales in a wide variety of porous and fractured geological formations. Over many …

Understanding the role of connectivity for the characterization of heterogeneous porous
aquifers or reservoirs is a very active and new field of research. In that framework …

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

A complete treatment of the theory and practice of groundwater engineering, The Handbook
of Groundwater Engineering, Second Edition provides a current and detailed review of how …

Heterogeneity can be dealt with by defining homogeneous equivalent properties, known as
averaging, or by trying to describe the spatial variability of the rock properties from geologic …

We describe the upscaled groundwater flow and solute transport characteristics of two‐
dimensional hydraulic conductivity fields with three fundamentally different spatial textures …

We investigate the spatiotemporal nonlocality underlying fractional-derivative models as a
possible explanation for regional-scale anomalous dispersion with heavy tails. Properties of …

The sustainability of irrigated agriculture in many arid and semiarid areas of the world is at
risk because of a combination of several interrelated factors, including lack of fresh water …

We review the basic mathematical concepts of random walk particle tracking (RWPT) and its
advantages and limitations. Three different numerical approaches to overcome the local …
