FIGURE 9.11
Measured and predicted nitrate nitrogen concentrations at various depths for Windsor soil.
tailing was not observed based on the experimental data, however. Results
for nonreactive tracer solute are shown in Figure 9.13. Here experimental
(symbols) and simulated (dashed and solid lines) breakthrough results for
tritium in a two-layered soil column (Sharkey clay → sand, column B) under
different layering orders are presented and clearly illustrate that the order
of layering does not influence solute transport under steady flow conditions.
