One of the issues hampering progress in modelling greenhouse gas (GHG) emissions from
soils is a lack of co-ordination between models originating from different disciplines: soil …

Diffusion in Natural Porous Media: Contaminant Transport, Sorption/Desorption and
Dissolution Kinetics introduces the general principles of diffusion in the subsurface …

The structure of macroporous or aggregated soils and fractured rocks is generally so
complex that it is impractical to measure the geometry at the microscale (ie, the size and the …

In this paper, we describe a one-dimensional, process-based model to simulate production
and transport of CO2 in soil (PATCIS). The model is used to predict CO2 efflux from the …

A mathematical model was derived to examine the impact of gas advection, gas diffusion,
gas‐water mass transfer, gas‐water partitioning, sorption, and intraaggregate diffusion on …

The use of soil venting or vacuum extraction for remediation of contaminated soil has lead to
an increased interest in modeling gas‐phase processes. The majority of existing transport …

Sorption from the vapor phase is an important factor controlling the transport of volatile
organic compounds (VOCs) in the unsaturated zone. Accurate description of sorption from …

The partitioning of volatile organic compounds (VOCs) in soil multiphase system is a critical
process for vapour intrusion, however, the importance of vapour-solid interface adsorption …

Determination of liquid-phase diffusion through unsaturated soils is important for estimating
contaminant transport in soils and design of remediation processes for contaminated soils …

Minimally intrusive geophysical methods are required to monitor CO2 leakages from
underground storage reservoirs. We investigate the impact of gaseous CO2 on both …
