Description	Analýza bromidového experimentu na ploše s drenážním systémem pomocí dvourozměrného modelu duální permeability (cs) Preferential flow has been hypothesized as an important factor for chemical leaching from tile-drained agricultural fields with structured soils originating from glacial till sediments. The objective of this paper was to analyze the tile outflow and leaching patterns using a two-dimensional dual-permeability and a standard approach for comparison. Simulated drainage rates and Br-effluent concentrations were made comparable with collector data from a field experiment by weighing results for irrigated and nonirrigated plots according to their area fractions. Results from the dual-permeability analyses suggest that conditions at the soil surface, near the water table, and of the field-scale mixing are significantly affecting leaching patterns, in addition to local nonequilibrium effects. The description of preferential flow toward tile drain could be strongly improved with the 2D-DPERM compared with the 2D-SPM.
