Název v původním jazyce

3D MRI visualization of the flow in heterogeneous undisturbed soil samples

Popis výsledku v původním jazyce

A video of 3D MRI images of water flowing through the undisturbed soil sample of coarse sandy loam was obtained during infiltration-outflow experiment. Two cases were monitored: Recurrent ponded and tension infiltration. Hydraulic pressure heads and fluxes were recorded. The air-dry soil core was visualized by X-ray Computed Tomography. For both the infiltration and drainage, flow irregularities were observed. Decrease of the steady-state infiltration rate occurred between two successive runs of pondedinfiltrations. From the images it may be assumed that the unstable behaviour is mainly due to the air phase in combination with the uneven distribution of local pore flow rates.
