Dealing with landscape heterogeneity in watershed hydrology: A review of recent progress toward new hydrological theory

PA Troch, GA Carrillo, I Heidbüchel… - Geography …, 2009 - Wiley Online Library
Predictions of hydrologic system response to natural and anthropogenic forcing are highly
uncertain due to the heterogeneity of the land surface and subsurface. Landscape …

Recent advances in scalable non-Gaussian geostatistics: The generalized sub-Gaussian model

A Guadagnini, M Riva, SP Neuman - Journal of hydrology, 2018 - Elsevier
Geostatistical analysis has been introduced over half a century ago to allow quantifying
seemingly random spatial variations in earth quantities such as rock mineral content or …

A kriging approach based on Aitchison geometry for the characterization of particle-size curves in heterogeneous aquifers

A Menafoglio, A Guadagnini, P Secchi - … Environmental Research and …, 2014 - Springer
We consider the problem of predicting the spatial field of particle-size curves (PSCs) from a
sample observed at a finite set of locations within an alluvial aquifer near the city of …

Generating random fields with a truncated power-law variogram: A comparison of several numerical methods

F Heße, V Prykhodko, S Schlüter, S Attinger - Environmental modelling & …, 2014 - Elsevier
In this study we describe and compare four numerical methods for the generation of random
fields with a truncated power-law variogram; the Fourier method, the Randomization …

A multimodel data assimilation framework via the ensemble Kalman filter

L Xue, D Zhang - Water Resources Research, 2014 - Wiley Online Library
Abstract The ensemble Kalman filter (EnKF) is a widely used data assimilation method that
has the capacity to sequentially update system parameters and states as new observations …

Entropy, fractality, and thermodynamics of groundwater pathways

M Schiavo - Journal of Hydrology, 2023 - Elsevier
This Work deepens the issue of groundwater connectivity and the behavior of permeable
(alluvial) pathways from a thermodynamic viewpoint. Groundwater pathways have been …

Multimodel B ayesian analysis of groundwater data worth

L Xue, D Zhang, A Guadagnini… - Water Resources …, 2014 - Wiley Online Library
We explore the way in which uncertain descriptions of aquifer heterogeneity and
groundwater flow impact one's ability to assess the worth of collecting additional data. We do …

Multiscale relationships between fracture length, aperture, density and permeability

SP Neuman - Geophysical Research Letters, 2008 - Wiley Online Library
Fractured rocks exhibit a hierarchical structure which renders their attributes scale‐
dependent. In particular available data indicate a tendency for fracture length scales to be …

Examining the influence of heterogeneous porosity fields on conservative solute transport

BX Hu, MM Meerschaert, W Barrash… - Journal of Contaminant …, 2009 - Elsevier
It is widely recognized that groundwater flow and solute transport in natural media are
largely controlled by heterogeneities. In the last three decades, many studies have …

Upscaling of solute transport in disordered porous media by wavelet transformations

M Moslehi, FPJ de Barros, F Ebrahimi… - Advances in Water …, 2016 - Elsevier
Modeling flow and solute transport in large-scale (eg) on the order of 10 3 m heterogeneous
porous media involves substantial computational burden. A common approach to alleviate …
