Water flow and chemical transport in structured soils or soils with macropore features have been modeled using dual or multi-continuum approaches. For dual continuum (also referred to as dual-permeability) media, it is assumed that both the matrix and macropore domains contribute to solute advection and dispersion at differing rates based upon pore-water velocity in the respective domains. In this paper, we present some of the factors such as variability in sorption and biodegradation between the two domains and with depth which may lead to further variations in solute concentration profiles in these soils. In addition, we find that the land management practices such as tillage and organic amendment cause a variation in organic carbon profile. Through sensitivity analysis, we show that the effect of sorption and degradation variability on 2,4-D concentration profile.
