Solute Mass Transfer Effects in Two-Dimensional Dual-Permeability Modeling of Bromide Leaching From a Tile-Drained Field

Popis výsledku v původním jazyce

Preferential flow (PF) depends on processes and structures in soil at the small scale and can affect flow and transport processes at much larger scales. For studying PF processes, the discharge and solute effluent from subsurface drained experimental fields has frequently been used as a field-integrated signal that included combined effects of macropore flow and lateral transport toward the drain. The objective of this study was to better understand effects of the mass transfer coefficients on bromide (Br) leaching in a two-dimensional dual-permeability concept. The Br leaching was simulated for data of a Br tracer irrigation experiment on a drained field at Bokhorst. Flow and transport in 2D vertical cross-sections was described using a numerical 2D dual-permeability model. For applied Br, influx of Br only in the soil matrix (SM) domain, only in the preferential flow (PF) domain, and proportional to the water influx in both domains was considered to assess the impact of small-scale r
