Analysis of unsaturated flow and transport in arid regions is important, not only in water
resource evaluation but in contaminant transport as well, particularly in siting waste disposal …

While gravity fingering of water in unsaturated sands has been demonstrated and studied
under constrained laboratory conditions, its significance under field conditions in the vadose …

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

Fracture transmissivity and detailed aperture fields are measured in analog fractures
specifically designed to evaluate the utility of the Reynolds equation. We employ a light …

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

Five physically based models for predicting liquid saturation from light transmission in 2D
laboratory systems containing translucent porous media were developed and tested …

Flow visualization experiments were conducted on a transparent replica of a natural, rough‐
walled rock fracture from the Stripa Mine, Sweden, for inlet conditions of constant pressure …

Microscale experiments can provide mechanistic insights into larger‐scale flow and
transport phenomena. Studies of the microscale mechanics involved in preferential flow in …

Understanding of single‐phase and multiphase flow and transport in fractures can be greatly
enhanced through experimentation in transparent systems (analogs or replicas) where light …

The structure of fractures in nature rock appears irregular and induces complicated seepage
flow behavior. The mechanism and quantitative description of fluid flow through rock …
