Modeling of Nonequilibrium Bromide Transport through Alluvial Gravel Vadose Zones

Dann, Rodney; Bidwell, V; Thomas, S; Wohling, T; Close, M

Description

Understanding solute transport and flux through the vadose zone is important for predicting potential contaminant loading to groundwater systems. Two dual-permeability models: mixing cell (MC) and HYDRUS 1D (H1DDP) were used to simulate long-term nonequilibrium Br- leaching using data derived from suction cup samples at two field sites (sampled to 7- and 4-m depths) on the Canterbury Plains, New Zealand. Effective model parameters were derived by inverse methods to represent average transport...[Show more]
