Description
  • The main objective of our research is the prediction of the transport of cadmium in structured soils in response to rainstorm events. To model the subsurface movement of cadmium we use single-domain code HYDRUS 5 (Vogel et al., 1996), as a reference code, and the two-domain model S_1D_Dual (Vogel et al., 2000). The latter of the two models is based on dual-permeability approach and allows for simulation of preferential flow effects. In our particular case, the use of single-permeability model may result in a significant under-prediction of the depth of cadmium penetration in case that preferential flow develops, i.e. due to the presence of macropores.

  • Cílem našeho příspevku je predikce pohybu kadmia v strukturní půdě během přívalové srážky. K účelu modelování transportu kadmia v půdním profilu byl použit tradiční koncept mechaniky kontinua zahrnutý v modelu HYDRUS 5 (Vogel et al., 1996) a model založený na existenci dvou pórových domén - model duální permeability S_1D_Dual (Vogel et al., 2000). Druhý numerický model umožňuje simulovat preferenční efekty při proudění vody a pohybu chemických látek v půdním prostředí. Použití pouze tradičního konceptu s jednoduchou pórovitostí by vedlo v našem případě k významnému podhodnocení průniku kadmia. (cs)
