FIG. 6. . Vertical cross-sectional images (2-m-wide section below application strip) presenting results of the two-dimensional dual-permeability model (2D-DPERM) solute transport simulation during nonequilibrium situation at Day 97.74 (i.e., shortly after the first irrigation) for (top) 2D distribution of Br concentrations in (top left) soil matrix (SM) and (top right) preferential flow (PF) domain, and (bottom) for 2D vertical distribution of solute mass transfer rates. Here Br was applied in the SM domain only, and solute transfer rate coefficient, 
ss, was assumed relatively high (Table 2).
