Using the dye tracer experiment for characterisation of parameters of the dual-permeability model

Popis výsledku v původním jazyce

This study is focused on the visualization of the preferential flow in different soil types using the dye tracer experiment. The field ponding dye infiltration experiments were performed in two soil types: Haplic Luvisol and Haplic Cambisol. The tensiondisc infiltrometer and the Guelph permeameter measurements were performed in the field at various horizons. In addition, the thin soil sections were made and micromorphological images were used to study soil aggregate structure and dye distribution at amicroscale. While preferential flow in Haplic Luvisol was caused by soil aggregation and biopores, preferential flow in Haplic Cambisol was caused only by biopores and large gravitational soil fractures. Information about the dual-domain geometry and thedual-permeability models in HYDRUS-1D and HYDRUS 2/3D were then used to simulate preferential flow in studied soil types.
