Emulsions are suspensions of droplets ubiquitous in oil recovery from underground
reservoirs. Oil is typically trapped in geological porous media where emulsions are either …

Dynamics of flowing air in partially water‐saturated, porous geological formations are
governed by a wide range of forces and parameters. These dynamics are reviewed in the …

Hydrocarbon production, gas recovery from shale, CO2 storage and water management
have a common scientific underpinning: multiphase flow in porous media. This book …

Integrated, process‐based numerical models in hydrology are rapidly evolving, spurred by
novel theories in mathematical physics, advances in computational methods, insights from …

Preferential flow, a major influence in unsaturated soil and rock almost everywhere, occurs
by multiple phenomenologically distinct hydraulic processes. For the mode known as …

The two major flow mechanisms in the vadose zone are uniform flow and preferential flow.
Both types of flow occur often simultaneously, but have considerably different consequences …

The application of percolation theory to porous media is closely tied to network models. A
network model is a detailed model of a porous medium, generally incorporating pore-scale …

Dry water repellent soils are difficult to wet, forcing water and solutes to flow via preferential
paths through the unsaturated zone. A tracer field experiment was used to investigate the …

Emphasizing pioneering achievements, this work offers a clear and systematic description of
various soil-water phenomena and their applications to soil problems such as water …

This paper attempts to introduce the work described in this special section on colloid
transport within a more general perspective of the evolution of our understanding of the …
