Empirical computation of reaeration coefficients generally requires knowledge of mean velocity and mean depth of a stream. A practical method for obtaining this knowledge is described herein. The method involves time-of-travel, streamflow, and cross-sectional measurements, the development of discharge-velocity curves, streamflow profiles, and the computation of cross-sectional areas. Values for mean velocity and mean depth are determined and related to mean discharge.
