The purpose of this project was to study two of the major assumptions of the hydrocarbon gas tracer technique for the measurement of reaeration rates. The first assumption states that the ratios of the reaeration rate coefficient to the desorption rate coefficients of ethylene and propane, R//E AND R//P, respectively, are constant and independent of temperature and mixing intensity. Mean values of the ratios were found to be 1. 14 for R//E and 1. 36 R//P. These values compared well to the values of 1. 15 and 1. 39 reported by previous experimental studies. The second assumption which was studied states that losses of dissolved ethylene and propane due to adsorption on suspended sediment and organic material are negligible. The results of the tests showed that the adsorptive losses of ethylene and propane were negligible within the accuracy of the hydrocarbon measurement techniques.
