Journal Article
Published: 01 February 2012
Vadose Zone Journal (2012) 11 (1): vzj2011.0100.
... helical computed tomography (CT). This method provides new quantitative information on preferential flow processes occurring in an unsaturated undisturbed soil. Twenty-four three-dimensional images were acquired every 3 min in transient flow regime and every 5 min in stationary flow regime during...

... with X-ray computed tomography while controlling the hydric state and monitoring N 2 O fluxes. We used a multistep outflow system to apply two wetting–drying cycles to an undisturbed soil. The soil core was scanned with coarse-resolution X-ray computed tomography, one time during wetting and several...

..., breakthrough experiments, and X-ray computed tomography (CT) on large soil columns. Substantial structural heterogeneity that resulted in significant variations in flow and tracer transport was observed, despite the textural similarity of the investigated samples. Quantification of macropore characteristics...

... soil structure with less soil crusting and surface sealing and discuss drivers for soil structural stability. Using model media ranging from glass beads to crushed tuff, Kulkarni et al. (2012) developed and tested an improved method for image segmentation of x-ray computed tomography (CT) data...
