Soil Water Flow Dynamics Studied by Neutron Imaging
Original language description
The wetting dynamics of the water infiltration into a porous soil system has a strong influence on the amount of entrapped air inside the soil. Simultaneously, a higher volume of entrapped air obstructs a water flow. This effect is more noticeable in soils with preferential pathways because the soil matrix has a higher capillary forces and therefore the air is accumulated in preferential pathways. In the presented study, two experiments were conducted on the same sample. The first experiment was performed under the constant water level condition (CWL) and the second experiment under the constant water flux condition (CWF) at the top of the sample. Infiltration experiments were monitored by neutron radiography and tomography at Paul Scherrer Institut in Switzerland (stations BOA and NEUTRA). From series of corrected radiograms taken at different angles three-dimensional (3D) image was reconstructed. Then the series of 3D images mapped the wetting of the porous system over the corresponding phase of infiltration process.
