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 …
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 …

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 …

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 …
This Work deepens the issue of groundwater connectivity and the behavior of permeable (alluvial) pathways from a thermodynamic viewpoint. Groundwater pathways have been …
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 …
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 …

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 …
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 …
