Název v původním jazyce

Short-term transport of cadmium during a heavy rain event simulated by a dual-continuum approach

Popis výsledku v původním jazyce

The objective of this study was to examine transport of cadmium (Cd) in response to an extreme rainfall event for three different soils using numerical modeling. The Cd transport during a single rain event was predicted with the S1D model for light, medium-heavy and heavy soil in the same region. The cadmium transport through the soil profile was simulated by the one-dimensional dual-permeability model. The rainfall event with extremely high rainfall intensity induced deep penetration of cadmium in themedium-heavy and heavy soil, which may indicate increased vulnerability to shallow groundwater pollution for the respective sites in Danubian Lowland region. The highest cadmium leaching was predicted for heavy clay soil, where the preferential particle-facilitated transport of cadmium through the soil profile was significant due to the contrasting properties of the soil matrix domain and the preferential flow domain.
