Mathematical Modeling of Small Watercourse Pollution by Biogenic Substances in the Nonchernozem Zone of the Russian Federation

S. N. Kovalenko

The pollution of surface inland waters under the influence of anthropogenic activity is of the global nature. A process of the pollutant concentration formation is considered as the stochastic one. The dividing of observational series into separate time periods is proposed to obtain the homogeneous series of the pollutant concentration. A technique of the mathematical modeling of pollutant concentration taking account and regardless of the autocorrelation dependence is given. The results of mathematical modeling of biogenic substance concentration in small watercourses in the northwest of the Russian Federation are estimated.
