A comparison of Eulerian and Lagrangian transport and non-linear reaction algorithms
(Elsevier, 2017-01)
Article
Open AccessWhen laboratory-measured chemical reaction rates are used in simulations at the field-scale, the models typically overpredict the apparent reaction rates. The discrepancy is primarily due to poorer mixing of chemically ... -
A locally adaptive kernel regression method for facies delineation
(2015-12-01)
Article
Open Access -
A random walk solution for modeling solute transport with network reactions and multi-rate mass transfer in heterogeneous systems: Impact of biofilms
(Elsevier, 2015-12)
Article
Open AccessThe interplay between the spatial variability of the aquifer hydraulic properties, mass transfer due to sub-grid heterogeneity and chemical reactions often complicates reactive transport simulations. It is well documented ... -
Assessing the joint impact of DNAPL source-zone behavior and degradation products on the probabilistic characterization of human health risk
(Elsevier, 2016-02)
Article
Open AccessThe release of industrial contaminants into the subsurface has led to a rapid degradation of groundwater resources. Contamination caused by Dense Non-Aqueous Phase Liquids (DNAPLs) is particularly severe owing to their ... -
Elimination of the reaction rate 'scale effect': application of the Lagrangian reactive particle-tracking method to simulate mixing-limited, field-scale biodegradation at the Schoolcraft (MI, USA) site
(2017-12)
Article
Open AccessMeasured (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 reduced rates are commonly attributed ... -
Probabilistic human health risk assessment of degradation-related chemical mixtures in heterogeneous aquifers: risk statistics, hot spots, and preferential channels
(2015-06)
Article
Open AccessThe increasing presence of toxic chemicals released in the subsurface has led to a rapid growth of social concerns and the need to develop and employ models that can predict the impact of groundwater contamination on human ... -
Toward efficiency in heterogeneous multispecies reactive transport modeling: A particle-tracking solution for first-order network reactions
(2014-09)
Article
Open AccessModeling multispecies reactive transport in natural systems with strong heterogeneities and complex biochemical reactions is a major challenge for assessing groundwater polluted sites with organic and inorganic contaminants. ...
