Simulated rainfall runoff event hydrographs. Each marker on the line represents a sample.

 


Fig. 4.

Cumulative transport of bifenthrin in over-irrigation runoff and simulated rainfall runoff. For each event, the first sample represents the first 1.89 liters of runoff; the second sample represents 18.9 L, and all successive samples represent 37.8 L intervals.
