Multiphase and Multi-component Interactions through the Unsaturated Saturated Zone Field and Model S We note a vertical, gravity driven, NAPL vertical displacement of the gaseous phase the velocity of which is also influenced by the gaseous pressure gradient. Fluids densities depend on TCE concentration, we thus note a density driven flow pattern. As TCE concentration decreases away from the NAPL

Solute contaminant transport in variably saturated dual-porosity/dual permeability chalk: field trac. The tracer experiments performed in the chalk were modelled using the finite element flow and transport simulator SUFT3D. The mathematical representation of the unsaturated properties of the fissured chalk is based on a new modified van Genuchten — Mualem relationship that takes into account the d

Hydrogeophysical characterization of subsurface solute transport at the Krauthausen test site: experlocal concentrations using an empirically derived relation with the tracer (bromide) concentration. The spatial variation of the stream tube local dispersion and stream tube velocity in the reference plane was then derived. This information can also be used to derive inversely the statistical proper

Biogeochemical modeling of reactive transport applied to laboratory and field studies on jet-fuel coment with measured biodegradation, mineralization and pyrite oxidation rate, and reproduced the overall microbial processes well, but they failed to mimic the observed ferrous iron. A dual porosity approach should be included..The second case with a jet-fuel contaminated plume under monitoring was s

Assessing the potential for natural or enhanced in-situ bioremediation at a TCE-contaminated site byd with modeling results might suggest the feasibility for enhancing . reductive dechlorination at the investigated site in order to achieve the stringent legislation limits. Such promising results will be verified through a field test performance before implementing the process at full-scale.
