Abstract
A method is proposed for assessing nutrient pollution flows in the catchment - water body system, based on the following indicators: the eutrophication potential of the catchment area and water body, the eutrophication potential of diffuse pollution of the catchment area of a water body, the potential for retaining biogenic pollution in the catchment area of a water body. The components of the eutrophication potential for the catchment area of the river Kazanka, located in the left - bank of the Kuibyshev reservoir. It has been established that the eutrophication potential of the catchment area and the waters of the river Kazanka for nitrogen and phosphorus compounds is 2259 and 170 and 705 and 56 t • year −1, respectively. It is shown that the potential for retaining nutrient pollution in the catchment area of the river Kazanka of nitrogen and phosphorus compounds is 69 and 67%, respectively.
