dcterms:description
Aims The main aim of this study was to validate the HYDRUS-2D model for the simulation of Cd, Cu, Pb and Zn transport within a soil column and their accumulation by willows. Methods A simulation of metal transport and uptake by willow was implemented using the HYDRUS-2D code. Two scenarios of the column experiment were compared: soil (C) and soil with planted willows (V). Seeping water, soil water content and actual transpiration were measured. Metal contents in soil water and willows were analysed. Results The single-porosity model (applied for isotropic soil media) was sufficient for scenario C. The single-porosity (applied for anisotropic soil media) and dual-porosity models (characterizing non-equilibrium water flow) were explored in scenario V. Measured cumulative Cd and Zn uptake showed a 20- and 10- times higher accumulation, respectively, in comparison with the modelled ones. On the other hand, modelled cumulative Pb uptake was reduced by reducing the maximum value of the root uptake concent Aims The main aim of this study was to validate the HYDRUS-2D model for the simulation of Cd, Cu, Pb and Zn transport within a soil column and their accumulation by willows.
