R. A. Gardner 1986 Time-of-travel and reaeration data were collected between June 1983 and August 1984 for seven small streams in Alabama. Rhodamine WT was used as a tracer for all the studies and propane was used in the reaeration studies. Mean velocities through the study reaches ranged from 0.06 to 0.67 ft/sec. Computed reaeration coefficients, corrected to 20 C, ranged from 1.7 to 45.8 days-1.
