In heterogeneous porous aquifers, simulations and predictions of groundwater flow and
solute (contaminant) transport require detailed knowledge of aquifer parameters and their …

Tracer testing is a mature technology used for characterizing aquatic flow systems. To gain
more insights from tracer tests a combination of conservative (non-reactive) tracers together …

A comprehensive understanding of the transport and fate of per-and poly-fluoroalkyl
substances (PFAS) in the subsurface is critical for accurate risk assessments and design of …

Multiphase flow and contaminant transport in porous media are strongly influenced by the
presence of fluid‐fluid interfaces. Recent theoretical work based on conservation laws and …

Studies of NAPL dissolution in porous media have demonstrated that measurement of
saturation alone is insufficient to describe the rate of dissolution. Quantification of the NAPL …

Pore-scale processes govern fundamental behavior in multiphase porous media systems. A
high-resolution, three-dimensional image of the interior of a multiphase porous media …

Fractured rock is the host or foundation for innumerable engineered structures related to
energy, water, waste, and transportation. Characterizing, modeling, and monitoring fractured …

Several innovative tracer techniques have been introduced during the past 5 years for
enhanced characterization of the “source zones” at sites contaminated with non-aqueous …

This volume is meant to provide the practitioner with information on the natural mixing
processes occurring in aquifers as well as to describe basic strategies that can be …

A series of gaseous miscible displacement experiments were conducted to estimate specific
air–water interfacial areas (ai) and water contents in an unsaturated sand column. A straight …
