| Abstract: | The radioactive and modified tracer techniques were used to measure the reaeration coefficients of two reaches each of Black Earth Creek and the Madison Effluent Channel near Madison, Wis. Coefficients measured with the modified technique were from -8.96 to +3.61 and from +15.7 to +32.2 percent different from the coefficient measured with the radioactive tracer technique on Black Earth Creek. The larger coefficients measured with the modified technique on the second reach were attributed to increased wind conditions during the latter part of the modified-technique experiment. Interpretation of the Madison Effluent Channel study was complicated by an unsteady flow condition during the modified-technique experiment which required estimation of the dye loss and the discharge increase. Using these estimated values, the coefficients measured with the modified technique were from +25.3 to +57.9 and from -4.74 to +2.94 percent different from the coefficient measured with the radioactive technique on the Madison Effluent Channel. Results of this study suggest that the modified technique is a promising alternative to the use of radioactive tracers. (Woodard-USGS) |
