Results from the 9.6 mm h–1 (left) and the 6.2 mm h–1 (right) experiments: (A) breakthrough curves showing the relative concentration both as a function of time and the cumulative water input (the insets show early time behavior), (B) breakthrough curves in log-log plot, and (C) cumulative tracer recovery.

Results for the solute (left) and the colloidal tracer (right) at 4 mm h–1: (A) breakthrough curves showing the relative concentration both as a function of time and the cumulative water input (the insets show early time behavior), (B) breakthrough curves presented in log-log plot, and (C) cumulative tracer recovery.
