Problem Statement. The pollutant intake into water bodies is one of the issues of urban areas. The pollutant input from the residential area of the city with surface runoff can many times exceed the input of pollutants from industrial and recreational areas, as well as from point pollutant sources. The objective of the study is 1) assess the distribution of chemical elements in catchments of water bodies in an urbanised area, 2) accumulation of chemical elements in solid matter of bottom sediments of surface water bodies with catchments in the functional areas of the city, 3) identify the main mechanisms of transfer of elements in solid matter from catchments to water bodies. The study was conducted on the example of Ekaterinburg (Russia). The material for the study consisted of the results of a landscape environmental and geochemical survey carried out in the city area in 2019-2021. Results. The distributions of element concentrations between functional landscape zones in the catenaries of the Kharitonovsky Garden and Chemodanchik reservoir catchments in Ekaterinburg were obtained. The distributions of metal concentrations in the catchment components show a tendency for the transfer of substance of different origin from the landscape components by lateral migration flows to the local basis of denudation (a drainless surface water body). At the same time in the bottom sediments of the reservoir there is a multiple accumulation of both pollutants and elements of typomorphic association. Dust fractions are the main carrier of contaminants in catchments.
