Colloids have the potential to enhance the mobility of strongly sorbing radionuclide contaminants in groundwater at underground nuclear test sites. This study presents an experimental and numerical investigation of colloid-facilitated plutonium trans

Aquifer heterogeneity controls spatial and temporal variability of reactive transport parameters and has significant impacts on subsurface modeling of flow, transport, and remediation. Upscaling (or homogenization) is a process to replace a heterogen

summary Identification of chemical reaction processes in subsurface environments is a key issue for reactive transport modeling because simulating different processes requires developing different chemical–mathematical models. In this paper, two so

Unsaturated compacted bentonite is the buffer material foreseen for deep geological high-level radioactive waste repositories because it provides mechanical and chemical stability, hydraulic isolation, and radionuclide retardation. FEBEX (Full-scale

Multiphase, multicomponent numerical models of long-term unsaturated-zone liquid and vapor movement were created for a thick alluvial basin at the Nevada Test Site to predict present-day liquid and vapor fluxes. The numerical models are based on rece

An extensive set of chlorine-36 (36Cl) data has been collected in the Exploratory Studies Facility (ESF), an 8-km-long tunnel at Yucca Mountain, Nevada, for the purpose of developing and testing conceptual models of flow and transport in the unsatura

Predictions of subsurface radionuclide transport are used to support the groundwater pathway analysis for the performance assessment of the low-level, solid radioactive waste site at Los Alamos National Laboratory. Detailed process-based models rathe

The computational burden associated with multidimensional, multicomponent, numerical solute transport models can be prohibitive. To solve these CPU intensive problems efficiently and accurately, we have implemented and extended a local adaptive grid

[1] In this study, we present first-order (in terms of the log conductivity variance) analytical solutions to displacement covariances Xij and macrodispersion coefficients Dij for transport of conservative solutes in two-dimensional, bounded heteroge
