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 …

To better inform the subsurface scientist on the expected performance of parallel simulators,
this work investigates performance of the reactive multiphase flow and multicomponent …

Stochastic Subsurface Hydrogeology is the study of subsurface, geological heterogeneity,
and its effects on flow and transport process, using probabilistic and geostatistical concepts …

Surface flow and subsurface flow constitute a naturally linked hydrologic continuum that has
not traditionally been simulated in an integrated fashion. Recognizing the interactions …

Highly-resolved simulations and flow and transport in an alluvial system at the Lawrence
Livermore National Laboratory (LLNL) site explore the role of diffusion in the migration and …

ParFlow (PARallel FLOW) is an integrated hydrology model that simulates surface and
subsurface flow. ParFlow [2, 23, 28, 34] is a parallel simulation platform that operates in …

The impact of three-dimensional subsurface heterogeneity in the saturated hydraulic
conductivity on hillslope runoff generated by excess infiltration (so-called Hortonian runoff) is …

Flow of uniform mean velocity U takes place in a formation of spatially variable, random
conductivity K (x). Advective transport of a plume of an inert solute is investigated by the …

The influence of the vadose zone, land surface processes, and macrodispersion on the
shape and scaling behavior of residence time distributions of baseflow is studied using a …

The recently introduced geological entropy concept evaluates spatial order/disorder in the
structure of the hydraulic conductivity (K) field to explain and predict certain characteristics of …
