Pumping test characterization of deep vadose zone properties Open
To analyze contaminant transport in a deep vadose zone (DVZ) such as that found beneath the 200 Area of Hanford one must characterize its saturated and unsaturated hydraulic properties. There presently are no known ways to do so directly o…

Observation and analysis of a pronounced permeability and porosity scale-effect in unsaturated fractured tuff Open
Over 270 single-hole (Guzman et d., 1996) and 44 cross-hole pneumatic injection tests (Illman et al., 1998; Illman, 1999) have been conducted at the Apache Leap Research Site (ALRS) near Superior, Arizona. They have shown that the pneumati…

Mean and variance of DNAPL ringer development in a saturated, randomly heterogeneous porous medium. Open
Chlorinated organic solvents such as TCE and PCE are among the most ubiquitous and problematic groundwater contaminants at many sites. They usually enter the subsurface in the form of organic liquids which exhibit low miscibility with wate…

Comment on hess-2023-15 Open
Abstract. The geostatistical characterization of the subsurface is confronted with the double challenge of large uncertainties and high exploration costs. Making use of all available data sources is consequently very important. Bayesian in…

Geostatistical representation of multiscale heterogeneity of porous media through a Generalized Sub-Gaussian model Open
<p>Characterization of spatial heterogeneity of attributes of porous media is critical in several environmental and industrial settings. Quantities such as, e.g., permeability, porosity, or geochemical parameters of natural systems a…

Twenty Lessons Drawn From My Subsurface Hydrology Career Open
This personal perspective complements a Brief Autobiography I (Figure 1) wrote for the journal Ground Water (Neuman, 2008). Whereas there I described my personal life from early childhood to my career stage at the time, here I focus on key…

Theoretical analysis of non‐<span>G</span>aussian heterogeneity effects on subsurface flow and transport Open
Much of the stochastic groundwater literature is devoted to the analysis of flow and transport in Gaussian or multi‐Gaussian log hydraulic conductivity (or transmissivity) fields, ( x being a position vector), characterized by one or (less…

Inverse modeling of unsaturated flow using clusters of soil texture and pedotransfer functions Open
Characterization of heterogeneous soil hydraulic parameters of deep vadose zones is often difficult and expensive, making it necessary to rely on other sources of information. Pedotransfer functions (PTFs) based on soil texture data consti…

Comment on “Advective transport in heterogeneous aquifers: Are proxy models predictive?” by A. Fiori, A. Zarlenga, H. Gotovac, I. Jankovic, E. Volpi, V. Cvetkovic, and G. Dagan Open
Fiori et al. (2015) examine the predictive capabilities of (among others) two “proxy” non‐Fickian transport models, MRMT (Multi‐Rate Mass Transfer) and CTRW (Continuous‐Time Random Walk). In particular, they compare proxy model predictions…

Comment on “Is unique scaling of aquifer macrodispersivity supported by field data?” by A. Zech et al. Open
Zech et al. [2015] reevaluate published estimates of longitudinal dispersivity from field experiments in unconsolidated porous materials to deduce that available data do not support a unique scaling law for “macrodispersivities.” Consideri…

Theory and generation of conditional, scalable sub‐<span>G</span>aussian random fields Open
Many earth and environmental (as well as a host of other) variables, Y , and their spatial (or temporal) increments, Δ Y , exhibit non‐Gaussian statistical scaling. Previously we were able to capture key aspects of such non‐Gaussian scalin…

New scaling model for variables and increments with heavy‐tailed distributions Open
Many hydrological (as well as diverse earth, environmental, ecological, biological, physical, social, financial and other) variables, Y , exhibit frequency distributions that are difficult to reconcile with those of their spatial or tempor…

Scalable statistics of correlated random variables and extremes applied to deep borehole porosities Open
We analyze scale-dependent statistics of correlated random hydrogeological variables and their extremes using neutron porosity data from six deep boreholes, in three diverse depositional environments, as example. We show that key statistic…
