Název v původním jazyce

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

Popis výsledku v původním jazyce

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.
