Generalized one-dimensional model of self-purification and dilution processes of sewage water in the distributed river system

Abstract

Paper presents the new approach to the synthesis of the generalized one-dimensional model of the self-purification and dilution processes of the river pollutants inflowed with sewage. The mathematical model for the calculation of indices range changing of river water quality, i.e. the mathematical model allows to determine both minimum and maximum values of the given index of river water quality in each river station has been developed. The mathematical model is applicable to small and middle rivers, in the first approximation the one-dimensional mathematical models of the dilution and admixing processes of sewage with river water can be applied.
