Large plain reservoirs are water bodies of a slow water exchange with Кw less than 10 year-1 contributing to multi-year (annual) flow regulation. All reservoirs of the Volga-Kama cascade belong to this type of reservoirs, except the Cheboksary and Saratov reservoirs with Кw about 20 year-1. Weekly and daily fluctuations of the runoff are observed in these reservoirs. This mode of operation of hydraulic constructions leads to an increase in the flow rate and fluctuations of the level, which determines the specific conditions for the formation and accumulation of bottom sediments characteristic of river systems. It is shown that the areas of coarse-grained sediments are 55 and 70%, respectively. The reservoirs under consideration are transit reservoirs for suspended substances and aerators for the oxidation of chemical pollutants and their neutralization, so they play a crucial role in the natural self-purification and management of natural water quality. Methods. The aim of the study is to characterize the spatial and temporal transformation of the lower layer of the ecosystem in reservoirs with high water exchange (by the example of the Cheboksary and Saratov reservoirs) and to identify its role in water self-purification taking into account biomarkers. It is known that river systems or systems similar to them are more efficient and are characterized as potentially saturated with food organic/mineral resources for hydrobionts. The assessment of water quality and bottom sediments of different hydro-morphometric characteristics, dynamics of water masses and operating conditions is presented using methods of bioassay and toxicology by the example of chironomid larvae and antioxidant defense system of benthic fish. Results. Based on the data of the integrated hydrobiological cruises during the growing season 2014–2020, it is difficult to say that the quality of water and bottom sediments, biotic and toxicological parameters depend on the flow rate, so further studies are required. The work is original, because there are no analogues in the world for monitoring of bottom sediments in reservoirs and quantitative assessment of sedimentation processes in space and time. The results of the biogeochemical analysis indicate, that in terms of the degree of deterioration of the eco/toxicological state, the Volga reservoirs are in a series: Volgograd = Saratov > Kuibyshev > Cheboksary > Gorky.

The real-time water discharge computation involves practical real-time computation of water discharge values to ensure forecasting and preventing dangerous hydrological phenomena, as well as daily monitoring of river water content and information support for the functioning of water management facilities in river basins. Nowadays the task of the real-time discharge accounting is very relevant. The article presents the outcomes of the study of two methods of computation of the real-time water discharges in the conditions of the unsteady flow that enable to pass to automatic operative accounting of the river flow. The first method is based on using of optimal extrapolation of the relative deviations of the measured water discharges from the reference rating curve obtained from the data of water discharge measurements for previous years. The second method is a new approach based on the Jones formula. The parameters of the Jones formula were obtained from measurements of water discharge over the past years using an optimization tool based on the generalized reduced gradient method. The daily real-time water discharges calculated in two ways were compared with the daily water discharges published in the reference books of the water cadaster «Daily data on the regime and resources of land surface waters». As a result, it was found that both methods can be used for automated real-time water discharge computation in conditions of unsteady flow.

The article presents an analysis of the long-term dynamics of the hydrochemical conditions of the water of the Shershnevsky reservoir for 1972-2020 during the spring flood and summer low water. The features of the development of water quality indicators over time are determined: pH, mineralization, turbidity, color, suspended solids, the content of dissolved oxygen and organic substances by permanganate oxidability and BPK5, as well as changes in the concentrations of ammonium, nitrite, nitrate nitrogen and phosphates. In the water of the Shershnevsky reservoir for the period 1972-2020, trends of a significant decrease in mineralization, turbidity and permanganate oxidability were noted in both phases of the hydrological mode. In the summer low water period, a significant increase in chromaticity, oxygen content in water and orthophosphates was detected.. The revealed features of changes in the hydrochemical regime indicate an increase in the processes of anthropogenic eutrophication of the Shershnevsky reservoir – the only drinking source of the Chelyabinsk agglomeration and make it possible to predict the state of the aquatic ecosystem. The information obtained can be implemented in the process of making management decisions on environmental protection measures for the Shershnevsky reservoir.

The objective of the article is assessment of many-year changes of the Lena River basin rivers’ runoff on the territory of Trans-Baikal Kray and its correlation with atmospheric precipitation as a leading factor of the water flow formation. Studying of the rivers’ water regime and determination of their water content cycles is especially relevant in view of extreme climate changes over the past decades and the necessity to elaborate a strategy of sustainable social/economic development of regions in contemporary conditions. However, the Lena River basin hydrological characteristics within the boundaries of Trans-Baikal Kray have been studied insufficiently. Methods. The analysis was carried out according to the data on the average monthly water consumption over the period from 1976 to 2018. To analyze the current climatic conditions we have used air temperature and atmospheric precipitation observation data from six meteorological stations. When used Pearson correlation analysis we have revealed correlation between the runoff at the posts under study and its within-year dynamics, as well as have calculated the connection with atmospheric precipitation. We have revealed many-year tendencies of the water flow by calculation and analysis of linear trends computed by the least-squares method and by plotting differential integral curves. Results. More than 80 % of river runoff is formed during the spring-summer period, at that the total winter (December-March) runoff on the average is less than 2 % of the annual runoff. In the studied sections of large rivers (Chara, Olekma), the average annual water discharge varies from 3.20 to 54.5 m3/s, small (Karenga, Bugarikhta, Kuanda) – from 10.2 m3/s up to 47.3 m3/s. The greatest consistency of water discharges is noted for the spring (April-June) and summer (July-September) hydrological seasons, since it is due to the distribution of atmospheric precipitation during the year, with which their significant correlation was revealed. During the study period, the full cycle in the sections of the studied rivers was not traced, which most likely indicates its longer duration relative to other rivers of the Trans-Baikal Kray. At present, we observe the high-water phase of the hydrological cycle.

In the conditions of climate change and increase of anthropogenic load upon environment ,one of the main direction of scientific hydrological research in the nearest decades will be assessment of water resources. The paper presents the results of assessment of the Lenkoran Nature Region river water status change over the period from 1990 to 2017 based on observation data from 13 closing ranges. The computations were carried out with taking into account runoff data of the rivers. Considerable number of the points has short observation series or gaps in observations; therefore, we in advance have reduced short series to the single many-year period. Runoff from the territories that had not been covered by hydrometric measurements was determined by computations by the analog rivers’ runoff or by the runoff maps. When assessing water resources for a number of ranges affected by economic activities, we have used the data on water abstraction and disposal and results of researches on assessment of evaporation from the catchment surface. The carried out computations resulted in statement that natural average many-year annual runoff of the Lenkoran Nature Region rivers is 0.993 km3.

The relevance of research is particularly high for the Central Black Earth Region due to the high population density and the presence of numerous dispersed sources of environmental risk with a chemical type of impact on natural waters. People are forced to use water that does not meet health standards for drinking purposes, which poses a serious threat to their health. The article presents the results of calculating the non-carcinogenic risk from exposure of the body to priority chemicals (iron, manganese, nitrates) contained in the drinking water supply sources of the region, based on average annual concentrations at 174 monitoring points of control (m.t.c.) of the distribution network in settlements Voronezh Oblast. Methods. As a methodological basis for assessing environmental risks, the regulatory document R.2.1.10.1920–04 “Guidelines for assessing the risk to public health when exposed to chemicals that pollute the environment” was used. Results. According to the results of the study, it was revealed that nitrates remain the dominant indicator of drinking water pollution in the region. Calculations showed that in 9 settlements of 7 districts of the Oblast and the city of Voronezh (19 m.t.s. out of 174), the quantitative value of the non-carcinogenic risk poses an objective threat to the health of both children and adults living in these territories. The practical significance of the work is determined by the possibility of using the results of the study to improve regional water policy and increase the environmental safety and comfort of water use in the region.
