Structural Analysis of Water Quality Formation in an Urban Watercourse: Point, Non-Point, Transit, and Natural Components

Abstract

The decomposition of water quality formation of city watercourse was carried out. The ratio of natural and anthropogenic (local and transit) components of the watercourse water quality were determined in the case of the Belaya River. The mass of pollutants entering the water body from Ufa City territory through sources of different categories, including point and non-point, was estimated. It was established that the ratio of pollutant masses from point and non-point sources varies in different phases of water regime, depending on the pollutant type. In the study, it is shown that the system of river water quality monitoring should be improved taking into account the features of its formation within urban territory.
