Abstract
The formation history of the Irkutsk Reservoir is considered along with its effect on changes in the nearby area and water chemistry. The results of hydrochemical studies, carried out by the authors in 2022 in reservoir bays and tributaries are analyzed and compared with earlier studies. The waters of rivers flowing into the Irkutsk Reservoir were found to belong to sulfate-hydrocarbonate magnesium-calcium type. The chemistry of the waters of rivers, bays of the Irkutsk Reservoir in the key areas, where inhabited localities, cottage settlements, and garden plots are situated, was found to differ from the background chemistry and to be chloride-hydrocarbonate magnesium-calcium. The microelement composition of water in the major portion of the reservoir corresponds to the ranges of the basic concentrations of microelements at the source of the Angara River.

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‰.

Abstract
This paper presents the results of frequent observations of the intensity of production processes in the surface water layer in the Krasnovidovo pool of the Mozhaysk Reservoir from June 17, 2018 to September 26, 2018. Measurements were carried out using an automatic production meter developed by A.V. Goncharov, a system of water temperature recorders, subaquatic illumination, photosynthetically active radiation (PAR), and meteorological characteristics. No statistically significant relationship between gross production and the main predictors determining its value have been recorded throughout the measurement period, while its relationships with water temperature and illumination proved to be statistically significant for the period with no limitation of biogenic elements and for the autumn cooling period. According to the results, an important factor determining the amount of gross production is dynamic mixing.

Abstract
An isotope–hydrochemical study of the surface and groundwater was carried out in the basin of the Ala-Archa River located on the Northern slope of the Kyrgyz ridge, Kyrgyzstan. The results of studies of stable isotopes of δ2H and δ18O, the isotope composition of uranium and the physicochemical parameters were used to carry out the diagnostics of runoff components of the mountain river basin Ala-Archa and to determine river runoff components in the zone of development of modern glaciation. The contribution of buried ice to river flow was determined.

Abstract
The Kolyma is the largest river, the basin of which lies entirely in the zone of continuous permafrost and is subject to considerable climate changes, which affects its hydrological regime. The current dynamics of water flow and runoff-formation factors over 1979–2020 are analyzed, and the sensitivity of water regime characteristics of the Kolyma River to changes in climate parameters is studied. The comparison of the mean values of meteorological characteristics in the Kolyma basin over 2000–2020 with the mean values over 1979–1999 showed an increase in the normal annual air temperature by 1.3°C, the total annual precipitation increased by 8.3% with the most abrupt increase in September and March. According to observation data, the annual river runoff at the Kolymskoe gage (283 km from the Kolyma mouth), increased by 5.2%. Physical-mathematical models of river runoff formation have gained in popularity as a tool for studying the features of the water regime and its dynamics. In this study, the ECOMAG model is applied to the Kolyma R. basin, where its calibration and verification for two gages showed a good reproducibility of the actual water discharges. To better understand the mechanisms of the response of Kolyma water regime to changes in the climate characteristics based on ECOMAG model, the sensitivity of runoff characteristics to air temperature and precipitation was analyzed.

Abstract
The study of the isotope hydrogeology of bogs in the Northwestern Russia included the analysis of the potential of the integrated use of changes in the major hydrogeochemical characteristics of bog water and radon-222, an alternative marker of groundwater flow, in the hydrological continuum of the Ilasskii Bog Massif (IBM), which is a typical bog of the southern White-Sea type, common in the region. It was found that the hydrogeochemical runoff from the IBM forms mostly by internal bog water rather than by surface water bodies.

Abstract
A newly-developed high-resolution regional model of the Kara Sea was used to carry out numerical experiments aimed to study the dynamics and thermodynamics of the Kara Sea, as well as the evolution of river plumes and the influence of river runoff on the simulated thermohaline structure of waters. It has been found that the use of a daily-mean river runoff forcing in the model provides a model solution that is closer to the observed distribution of temperature and salinity compared to specifying a climatic monthly-mean river runoff.
