Representative hydraulic conductivities in saturated groundwater flow

X Sanchez‐Vila, A Guadagnini… - Reviews of …, 2006 - Wiley Online Library
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 …

Multifaceted nature of hydrogeologic scaling and its interpretation

SP Neuman, V Di Federico - Reviews of Geophysics, 2003 - Wiley Online Library
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 …

Convergence assessment of numerical Monte Carlo simulations in groundwater hydrology

F Ballio, A Guadagnini - Water resources research, 2004 - Wiley Online Library
Numerical Monte Carlo simulation is considered to be one of the main tools to be used in
groundwater hydrology (1) to quantify the uncertainty in the flow predictions due to imperfect …

Upscaling of flow in heterogeneous porous formations: Critical examination and issues of principle

G Dagan, A Fiori, I Jankovic - Advances in water resources, 2013 - Elsevier
We consider heterogeneous media whose properties vary in space and particularly aquifers
whose hydraulic conductivity K may change by orders of magnitude in the same formation …

Two‐dimensional characterization of hydraulic heterogeneity by multiple pumping tests

W Li, A Englert, OA Cirpka… - Water Resources …, 2007 - Wiley Online Library
The conventional analysis of pumping tests by type‐curve methods is based on the
assumption of a homogeneous aquifer. Applying these techniques to pumping test data from …

Correlation Structure of Steady Well‐Type Flows Through Heterogeneous Porous Media: Results and Application

G Severino, C Fallico… - Water Resources Research, 2024 - Wiley Online Library
Steady flow toward a fully penetrating well takes place in a natural porous formation, where
the erratic spatial variations, and the raising uncertainty, of the hydraulic conductivity K are …

Seismic diffusivity and the influence of heterogeneity on injection‐induced seismicity

R Haagenson, H Rajaram - Journal of Geophysical Research …, 2021 - Wiley Online Library
The spatiotemporal patterns of injection‐induced seismicity (IIS) are commonly interpreted
with the concept of a triggering front, which propagates in a diffusion‐like manner with an …

Uncertainty quantification in scale‐dependent models of flow in porous media

AM Tartakovsky, M Panzeri… - Water Resources …, 2017 - Wiley Online Library
Equations governing flow and transport in randomly heterogeneous porous media are
stochastic and scale dependent. In the moment equation (ME) method, exact deterministic …

Stochastic analysis of well‐type flows in randomly heterogeneous porous formations

G Severino - Water Resources Research, 2011 - Wiley Online Library
Well‐type flow takes place in a heterogeneous porous formation where the transmissivity is
modeled as a stationary random space function (RSF). General expressions for the …

Laboratory tracer tests on three-dimensional reconstructed heterogeneous porous media

C Danquigny, P Ackerer, JP Carlier - Journal of Hydrology, 2004 - Elsevier
Tracer tests have been performed on a 3D tank of dimensions 560× 100× 100 cm3. These
experiments at laboratory scale are used to define effective hydraulic conductivity and …
