"The dissolved oxygen concentration (DO) is one of the most important indicators of the water quality of a river. While many processes affect the dissolved oxygen balance in a river and the evaluation of the DO depends on the rates at which all these processes occur, many of these processes are biological and chemical in nature and cannot be easily modelled. However, the process of oxygen absorption from the atmosphere is a physical process and can be related almost entirely to the flow conditions in the river. This atmospheric reaeration rate is the measure of the self-purification capacity of a stream and is an essential piece of information for water quality modelling"--Introduction, page 1.
