The effect of temperature on the aeration of receiving waters is often described by an equation of the form KT = K20 θ(T-20) where K20 is the 20○ C value of the absorption coefficient and KT is the value at some other temperature, T. In the past, θ has been considered to be a constant with various values assigned to it by different investigators. It is shown that θ is not a constant but depends on the level of turbulence and temperature. Values of θ appropriate for streams are determined by using the film penetration model and experimental results. These values are compared with values reported in the literature.
