TL;DR: In this article, the authors used X-ray computed tomography (CT) scans to evaluate gas transport behavior in macropore networks under these conditions and found that CT-derived macroporosity and air-filled porosity for the limiting-quarter section of each column were highly correlated with both k a20 and T 5% (R 2 from 0.6 to 0.8).

TL;DR: In this article, X-ray computed tomography (CT) can be applied for this characterization, and in this study CT-derived parameters were used to explain water, air, and solute transport through soil.

TL;DR: In this paper, a combination of standard physical measurement methods for air and water permeabilities, breakthrough experiments, and X-ray computed tomography (CT) on large soil columns was used to establish links between the structural pore space and preferential transport.

TL;DR: In this paper, the authors used X-ray computed tomography (CT) to estimate hydraulic properties of macropore hydraulic properties in three horizons of an Andosol and a Gleysol.

TL;DR: In this article, the authors evaluated the contribution of roots in soil erosion control and the effect of root density in soil erodibility and soil physical properties, and found a positive correlation between soil shear strength and root density, but no influence of roots on bulk density and saturated hydraulic conductivity.
