The reliable identification of subsurface sedimentary structures (ie, geologic heterogeneity)
is critical in various earth and environmental sciences, petroleum reservoir engineering, and …

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 …

Reliable characterization of subsurface structures is essential for earth sciences and related
applications. Data assimilation‐based identification frameworks can reasonably estimate …

Hydrologically mediated hot moments (HM‐HMs) of transient anomalous diffusion (TAD)
denote abrupt shifts in hydraulic conditions that can profoundly influence the dynamics of …

Groundwater flow and mass transport predictions are always subject to uncertainty due to
the scarcity of data with which models are built. Only a few measurements of aquifer …

The complexity of mass transfer processes often complicates solute transport simulations.
We present a new approach for the implementation of the multirate mass transfer model into …

Understanding the effect of sample size on hydraulic characteristics of porous media and
estimating their scale-dependent properties have been challenging in subsurface hydrology …

Mounting evidence suggests ecosystem changes that alter subsurface water fluxes and
carbon dioxide concentrations in carbonate terrains may drive measurable changes in …

Random walk particle tracking (RWPT) is a well established and efficient alternative to grid‐
based Eulerian approaches when simulating the advection‐dispersion transport problem in …

Measured (or empirically fitted) reaction rates at groundwater remediation sites are typically
much lower than those found in the same material at the batch or laboratory scale. The …
