Variations of the Oxygen Isotopic Composition of the Yauza River within the City of Moscow in 2019–2021 under the Effect of Snow Melting and Heavy Rains
Abstract
Seasonal variations of the oxygen isotope composition (δ18O) of the Yauza River since June 2019 to November 2021 are studied based on weekly samples, along with the isotopic composition and amount of precipitation over this period in Moscow. The seasonal character of the isotopic composition variations is shown both for precipitation and river water with the amplitude of variations in the isotope characteristics in precipitation being appreciably higher than in river water. The features of changes in the isotopic composition of Yauza River water are shown for the periods of snow melting in 2020 and 2021, which differ in the amount of snow reserves in the preceding winter seasons and in the volumes of snowmelt water. It is also shown that heavy rains in spring and autumn can lead to rapid (within several hours or the next day after rain) changes in the isotopic composition of river water by 1.0–2.3‰.
期刊介绍：
Water Resources is a journal that publishes articles on the assessment of water resources, integrated water resource use, water quality, and environmental protection. The journal covers many areas of research, including prediction of variations in continental water resources and regime; hydrophysical, hydrodynamic, hydrochemical and hydrobiological processes, environmental aspects of water quality and protection; economic, social, and legal aspects of water-resource development; and experimental methods of studies.
