Fig. 2. Chloride concentration in drainage water in response to a Cl- pulse. The arrow indicates Cl discontinued in rainfall: (a) unsaturated flow (0.2 cm h-1 application rate, one replicate each of Hudson, Arkport, and Genesee soils); and (b) saturated flow (water applied under ponded conditions resulting in flow rates of 17.6 and 6.8 cm h-1 for Hudson and Genesee soils, respectively). Symbols are observed values. Lines are convective-dispersive equation best fits; parameter values are given in Table 3.
