Characterization of Potential Preferential Pathways in Soil Columns by X-ray Tomography and Infiltration Experiments
Original language description
Disturbances of soil structure, which originate from both biological and physical processes in soil often represents pathways of the preferential flow. Larger structures can be well identified by X-ray computed tomography (CT) of the soil. In this studythe regions of high porosity were identified. Five undisturbed soil columns from Cambisol and Oxisol series from different locations have been studied. Data from CT were analyzed in connection with the flow dynamics as monitored on the same soil columnsby experiments in laboratory. Experiments consisted of series of infiltration events done using modified tension infiltration disc placed on the top of the soil column. Cumulative outflow and the total mass of the soil core were recorded as well as pressure heads measured by tensiometers. Experiments revealed occurrence of the preferential flow for the soil from Cambisol series.
