    Impact of the biopores morphology on in.ltration properties of soil

  • Original language description

    Disturbances of soil structure, originated from biological activity, often represent potential pathways of the preferential flow. This study sums the results of experiments performed on five undisturbed soil columns, which were examined by the axial computed tomography (CT) and were the subject of the infiltration-outflow experiments. CT imaging was used to reveal the morphology of potential preferential pathways. The 3D reconstruction of biopore structure from CT images was done by means of segmentation based on the mathematical morphology operations pore erosion and dilation. The patterns of high porosity regions, which include also the empty biopores or biopores filled with loose material were reconstructed. The connectivity, total volumes and semivariograms of structures were analyzed in connection with the flow dynamics as monitored during infiltration-outflow experiments.

    Vliv morfologie biopórů na infiltrační vlastnosti půdy

  • Czech description

    Narušení půdní struktury způsobené biologicou aktivitiou často představuje potenciální cesty pro preferenční proudění. Tato studie představuje souhrn experimentů uskutečněných na pěti neporušených půdních vzorcích, které byly snímkovány počítačovou tomografií (CT) a byly na nich provedeny infiltračně výtokové experimenty. Snímkováním CT byly vizualizovány potenciální preferenční cesty. Byla analyzována konektivita, celkový objem, a semivariogramy potenciálních preferenčních cest.
