Reaeration-coefficient measurements of 10 small streams in Wisconsin using radioactive tracers : with a section on the energy-dissipation model

Reaeration-rate coefficients were measured for 10 small streams in Wisconsin using the radioactive-tracer method. The coefficients ranged from 2.06 to 55.2 per day (base e at 25 degrees Celsius). Stream discharges ranged from 0.3 to 37.0 cubic feet per second, most discharges being less than 10 cubic feet per second. Data also were collected for evaluation of the energy-dissipation model. The escape coefficient of 0.090 per foot at 25 degrees Celsius may be used for small streams similar to those studied. (Woodward-USGS).
