Dual-continuum modeling of dye tracer infiltration into soil with biopores
Original language description
Adequate modeling of infiltration into heterogeneous structured soils from ponded sources represents an important scientific problem with numerous implications for practical hydrological tasks. Reliable predictions of the 3D flow of water are often complicated by the presence of preferential pathways. The present study is focused on numerical modeling of a field infiltration experiment. The experiment involved ponded infiltration from a single infiltration ring into the soil profile containing biopores.The presence of biopores network in the soil of interest was proved by the accompanying tracer experiment. To quantify the preferential flow effects, numerical model based on the dual-continuum approach was employed. The spatial distribution approximatevolumetric fraction of the preferential pathways were evaluated by means of digital image analysis. The results provide valuable information about the movement of water through soils with biopores.
