Description	Není k dispozici (cs) CT images of dry undisturbed soil samples of the coarse sandy loam of Korkusova Hut and the fine sand of Hupselse Beek are analysed concerning the image resolution, the direction of scanning and the evaluation of a boundaries between the fast and slow flow domains. The image resolution appears to be a less important factor than the direction of scanning. Additional data sets are recommended for partitioning the fast and slow flow domains. Comparison is made with the tracer breakthrough pictures, MR images and outflow volumes obtained from infiltration outflow experiments. The two soils under study appeared to have essentially different flow dynamics. The fast flow in the KH sandy loam soil occurs in the high local porosity regions. However, in case of the HB fine sand the sample appeared to consist of a dense part, where the flow process took place, and the more porous part, which stayed dry. Flow instability was detected on MR images for the KH soil.
