Abstract
Two new methods for estimating the reaeration coefficient in rivers have been developed. The methods use measurements of dissolved oxygen and incident radiation with a solution to the oxygen mass balance equation. Parameters are estimated by minimizing the squared error between predicted and observed oxygen values. Night-time values of dissolved oxygen can be used to estimate the reaeration coefficient provided respiration is nearly constant. The coefficient can also be estimated by comparing net productivity with incident radiation. Field studies show the two methods to be reliable.
