FIG. 8. . Time series comparing measured and simulated results of (top) Br concentrations in tile outflow and (bottom) cumulative Br mass leaching. Curves are obtained with two-dimensional single porosity model (2D-SPM) and with two-dimensional dual-permeability model (2D-DPERM) for higher (2D-DPERM high) and lower (2D-DPERM low) values of the solute mass transfer rate coefficient, _ss, for the case of bromide application in both domains (Table 2). Blue columns indicate irrigation and a following rainfall event.
