Název v původním jazyce

Application of the single-porosity, dual-porosity and dual-permeability models for description of herbicide transport in the soil

Popis výsledku v původním jazyce

Non-equilibrium water flow and contaminant transport in soil porous media are frequently observed phenomena. Numerical models that assume bi-modal soil porous systems have been developed to describe non-equilibrium flow and solute transport. Single-porosity, dual-porosity and dual-permeability models in HYDRUS-1D (Šimůnek et al., 2003,2005) were applied in this study to estimate soil hydraulic parameters from laboratory multi-step outflow experiment via numerical inversion and to simulate chlorotolurontransport in the soil profile that was experimentally studied in the field. Two examples are shown here. First the applicability of single-porosity model for the simulation of herbicide transport in Haplic Luvisol is documented. Second the most suitablemodel for description of observed herbicide behavior in Greyic Phaeozem, which was influenced by preferential flow, is studied. Results of single-porosity, dual-porosity models are compared with the measured values. Concentrations simulat
