Currently, there is an increase in anthropogenic pressure on all ecological systems, including water bodies. It should be noted that the cost is high for experimental studies of the dynamics of the distribution of non-conservative impurities in the aquatic environment because they are associated with the use of expensive equipment (spectrophotometric, polarographic, spectrographic, etc.) and experimental facilities. In this regard, mathematical methods of modelling natural processes play an important role. In the work, a mathematical model is developed for studying the distribution of pollutants in rivers, taking into account chemical reactions, and the results of numerical experiments characterising the distribution of non-conservative nitrogen impurities in different periods of the year are presented.
