Deterministic Modeling of Bromide Tracer Transport During the Tracer/Time-Lapse Radar Imaging Test at the Boise Hydrogeophysical Research Site in August, 2001

Contaminant transport and remediation strategies are based on knowledge of site specific parameters and states (e.g., hydraulic conductivity, porosity, hydraulic gradient, plume density). Often

Heterogeneity and Prior Uncertainty Investigation Using a Joint Heat and Solute Tracer Experiment in Alluvial Sediments

In heterogeneous aquifers, imaging preferential flow paths, and non-Gaussian effects is critical to reduce uncertainties in transport predictions. Common deterministic approaches relying on a

Effects of uncertainty of lithofacies, conductivity and porosity distributions on stochastic interpretations of a field scale tracer test

We investigate the importance of selecting two different methodologies for the determination of hydraulic conductivity from available grain-size distributions on the stochastic modeling of the

Radial solute transport in highly heterogeneous aquifers: Modeling and experimental comparison

We analyze solute transport in a radially converging 3‐D flow field in a porous medium with spatially heterogeneous hydraulic conductivity (K). The aim of the paper is to analyze the impact of

Hydraulic travel time, attenuation, and steady shape inversions are complementary methods for tomographic aquifer characterization. In this work, a coupled procedure is pre-sented that facilitates

On single well forced gradient tracer tests : implications of aquifer physical heterogeneity and tracer behaviour

Single well forced gradient tracer tests are a potential cost-effective approach to estimate in situ aquifer contaminant fate and transport parameters for use in natural attenuation assessments and

How accurate is predictive modeling of groundwater transport? A case study of advection, macrodispersion, and diffusive mass transfer at the Forsmark site (Sweden)

We study predictive modeling of groundwater transport that accounts for three mechanisms: mean advection, macrodispersion, and mass transfer. A general methodology is presented and applied to a


A new method is proposed to delimitate wellhead protection areas in a confined aquifer where hydraulic conductivity is assumed as spatially random function. In a natural formation the heterogeneity



Integrating geophysical and tracer test data for accurate solute transport modelling in heterogeneous porous media

Aquifer heterogeneity has a critical influence on the subsurface movement of water and contaminants. To optimize remediation techniques or to delineate protection zones, heterogeneity has to be

Numerical simulation of tracer tests in heterogeneous aquifer

A large-scale, natural-gradient tracer test in a heterogeneous aquifer at a site near Columbus, Miss. is simulated using three-dimensional (3D) hydraulic conductivity distributions derived from the

Numerical modelling of reactive transport using aquifer analogue data

Even at well-instrumented groundwater research test sites like Borden or Cape Cod, the subsurface characterization of the aquifer systems is insufficient to predict the detailed transport of a

Evaluation of Reactive Transport Processes in a Heterogeneous Porous Aquifer Within a Non-Parametric Numerical Stochastic Transport Modelling Framework Based on Sequential Indicator Simulation of Categorical Variables

A non-parametric Monte Carlo type stochastic transport model is applied to simulate the simultaneous transport of nonreactive and reactive (sorptive) tracers in groundwater as observed during a

Nonreactive and reactive solute transport in three-dimensional heterogeneous porous media: Mean displacement, plume spreading, and uncertainty

The field-scale transport of reactive and nonreactive solutes by groundwater in a statistically anisotropic aquifer is examined by means of high-resolution, three-dimensional numerical solutions of

Design, performance, evaluation and modelling of a natural gradient multitracer transport experiment in a contaminated heterogeneous porous aquifer.

For the investigation of solute transport within a contaminant plume in a highly heterogeneous porous aquifer with complex boundary conditions, a natural gradient multitracer test was performed. In

Reactive transport in porous media: a comparison of model prediction with laboratory visualization.

Groundwater transport models that accurately describe spreading of nonreactive solutes in an aquifer can poorly predict concentrations of reactive solutes, demonstrating that models assuming complete mixing at the pore scale can overpredict reaction during transport.
