In this work, hydrochemical and hydromorphological characteristics of urban reservoirs of southwestern Belarus in the spring of 2020 were investigated. Hydromorphological characteristics of reservoirs were determined by field methods and GIS mapping methods. Hydrochemical assessment of water quality of reservoirs in the spring period was carried out according to 15 indicators. Multivariate statistical methods were used to analyze surface water quality. Based on the analysis of hydrochemical and

... hydromorphological indicators, an assessment of the ecological state of the reservoirs of the urboterritories of southwestern Belarus in the spring period of 2020 was given. During the study, patterns of distribution of morphometric characteristics of the reservoirs within the studied territory were established. The analysis of hydrochemical characteristics showed that the water quality of urban reservoirs depends on the types of anthropogenic effects.
