The content of oxygen dissolved in water is one of the most important factors in determining the self-cleaning ability of a stream. Program QUAL2E allows, among other things, to simulate cycles of oxygen, nitrogen, phosphorus and algae. The effect of concentration of dissolved oxygen is reflected through the internal source or through fraction functions, resp. In modelling of the course of concentration of dissolved oxygen alongside the stream a coefficient of reaeration plays an important role, it appears in source or through fraction function used to describe the degree of the change in concentration of this parameter and may be placed by eight different methods. It is evident from the results of numeric analysis at the given possibilities of calibration of different methods that the best result provide the methods in which calibration is performed. The other methods, i.e. methods which cannot be calibrated, give worse results in dependence on the season.
