Sustainable water management -- sustainable development indices -- water resources -- Yenisei River basin

Аннотация: A system of sustainable water management is suggested. This includes natural water production; acceptable sanitary-epidemiological water state; conservation and maintenance of biological water diversity; development of socioeconomic functions of water management; and instruments for water policy to conserve sustainable management of water consumption and protect consumers from injurious water effects. The developed system was applied to analyse the situation in the Yenisei River basin (Russia). Analysis in the basin showed that it is currently unsustainable: the share of purified water has not increased; water cost per unit production is high; the quality of water in the Yenisei River is still characterised as 'polluted'; some people in the basin drink water containing injurious substances; and both purification facilities and water supply systems are in an unsatisfactory state. Hence, the financing of hydrological work is currently inadequate.

phytoplankton -- productivity -- Volga -- Yenisei -- environmental factors -- geographic zoning

Аннотация: The relationship between plankton primary production and the geographic latitude suggests the dependence of biological productivity of water bodies on natural climatic conditions. Comparative analysis of the key factors governing phytoplankton productivity in the Volga and Yenisei rivers was made to reveal this relationship; these rivers represent two large river systems which extend in meridional direction, pass through various natural climatic zones, and differ in aquatic life habitats.

    Relationships between the biomass and production of bacterio- and phytoplanktonic communities
/ A. D. Aponasenko, L. A. Shchur // Microbiology. - 2016. - Vol. 85, Is. 2. - P243-248, DOI 10.1134/S0026261716020028 . - ISSN 0026-2617
Аннотация: Quantitative ratios of the biomasses of bacterio- and phytoplankton, interrelation of their production characteristics, and association of the functional characteristics with environmental factors were studied for Lake Khanka, the Yenisei River, and the Krasnoyarsk Reservoir. The ratio between the biomasses of bacterioplankton (Bb) and phytoplankton (Bp) in these water bodies was shown to vary within the range exceeding three orders of magnitude. Bacterioplankton biomass was relatively stable and varied from sample to sample by an order of magnitude. In more than 50% of the samples (total sample number, 495), bacterioplankton biomass exceeded that of the phytoplankton. The average Bb/Bp ratios for Lake Khanka, Yenisei River, and Krasnoyarsk Reservoir were 5.1, 2, and 1.4, respectively. Increased Bb/Bp ratios were found to correlate with elevated specific (per unit biomass) phytoplankton production. This finding indicated additional supply of biogenic elements to phytoplankton due to their recycling by bacterial communities. The ratio between bacterioplankton and phytoplankton production for Lake Khanka varied from year to year (0.07 to 0.76). For the Yenisei River and the Krasnoyarsk Reservoir these ratios were on average 0.19 and 0.27, respectively. According to the literature data for other water bodies, bacterial production may reach from 10 to over 100% of the primary production. The equilibrium density of bacterioplankton (maximal density of the population) in Lake Khanka was ~1.5 times higher than in the Yenisei River and the Krasnoyarsk Reservoir due to higher content of suspended mineral matter and associated organo-mineral detritus in the lake. The interaction between dissolved organic compounds sorbed on the surface of mineral particles results in chemical alteration of biochemically stable substrate into compounds which may be assimilated by aquatic microorganisms. © 2016, Pleiades Publishing, Ltd.

    Geoinformation Support and Web Technologies for Problems of Hydrobiological Monitoring of Yenisei River
/ A. Andrianova, N. Shaparev, O. Yakubailik // MATEC Web of Conferences. - 2016. - Vol. 79: 7th Scientific Conference on Information-Measuring Equipment and Technologies, IME and T 2016 (25 May 2016 through 28 May 2016, ) Conference code: 124242, DOI 10.1051/matecconf/20167901056 . -
Аннотация: Results of long-term hydrobiological monitoring for the Yenisei river section from the Krasnoyarsk hydroelectric power station dam to the village Zotino (Turukhansk district of the Krasnoyarsk region) are considered. Researching of zoobenthos showed significant changes of its structure after the Krasnoyarsk HPP dam construction. In particular, the proportion of amphipods (crustaceans) in the zoobenthos biomass increased by 10 times. In the expeditionary studies, seven species of amphipods were identified, but it should be noted that only two species develop and clearly dominate among them. Data obtained during the hydrobiological research formed the basis of geospatial database developed as a result of the work. The geospatial database with the observation results is available in the ICM SB RAS geoportal. The geoportal services provide data visualization in the form of interactive thematic maps, information about the objects on the map as "tooltips", information downloading in tabular form, direct access to the data through the web mapping services. Information and analytical support for the monitoring system based on the considered approach can simplify access to the needed information, provide new opportunities for analysis and modeling, promote the development of cross-disciplinary researches. © The Authors, published by EDP Sciences, 2016.

    Peculiarities of the antioxidant activity of tissues of rheophilic zoobenthic species in accordance to the results of chemiluminescent analysis
/ G. V. Makarskaya, A. V. Andrianova, S. V. Tarskikh // Contemp. Probl. Ecol. - 2016. - Vol. 9, Is. 5. - P574-581, DOI 10.1134/S1995425516050103 . - ISSN 1995-4255
Аннотация: Adaptations of living organisms to the environment are formed and manifested at different levels, from molecular to biocoenotic. Nowadays, the metabolic antioxidant system (AOS) is considered the key part of the process of adaptation; its activation is considered a general response of biota to the negative effect of the environment. The usage of AOS components as biomarkers of the stress condition in hydrobionts has good prospects; it is actively applied in the monitoring of aquatic ecosystems. Here, the kinetics of the free radical formation in various zoobenthic species from the Yenisei River (amphipods, oligochaetes, leeches, and chironomids) and in the amphipods from the Us River (a small mountain river, the Yenisei tributary) is analyzed. The parameters of kinetics of radical formation were registered in vitro in the homogenates of hydrobionts tissues under the initiation of the oxidative stress by the hydrogen peroxide using luminol-dependent chemoluminescence. In amphipods, unlike other invertebrates, the antioxidative activity is characterized by two chemiluminescent peaks. In addition, the kinetics of free radical elaboration has interspecific and agerelated variability in amphipods. In Gmelinoides fasciatus Stebb., the peak of the free radical elaboration and their total number significantly exceeded these parameters for Gammarus sp. and Eulimnogammarus viridis Dybowsky in a 60-min period. The increase of the production of free radicals in E. viridis and Gammarus sp. and its decrease in G. fasciatus were age-dependent. A significantly higher production of free radicals has been registered in G. fasciatus and E. viridis inhabiting the zone of elevated anthropogenic load in the Yenisei River. © 2016, Pleiades Publishing, Ltd.

cell size -- downstream of dam -- phytoplankton -- ratio between living and dead cells -- Yenisei River -- algae

Аннотация: Based on a daily examination of phytoplankton in the Yenisei River downstream of the Krasnoyarsk Hydroelectric Power Station (HPS) within a 4-year period, the ratio between living and dead cells is estimated and the size fractions of phytoplankton are described. It is found that, despite the certain negative effects of passing through the turbine blades of the high-head dam, high current speed, and influence of water discharges from the HPS, living algae cells dominate over dead ones in the water column of the studied reach of the Yenisei River during almost the entire year, except for several dates in late autumn and winter. It is shown that microphytoplankton (20–64 ?m in size) and nanophytoplankton (2–20 ?m), which make up 83% of the total algae count, pass through the turbine blades of the HPS and mostly remain undamaged, with the fraction of living cells varying from 21% in the winter period to 96% in the spring–summer period. © 2016, Pleiades Publishing, Ltd.

Аннотация: Адаптации живых организмов к условиям окружающей среды формируются и проявляются на самых различных уровнях - от молекулярного до биоценотического. В настоящее время метаболическая антиоксидантная система (АОС) считается ключевым звеном адаптационных процессов, а ее активация рассматривается как универсальный отклик биоты на негативное воздействие окружающей среды. Использование компонентов АОС в качестве биомаркеров стрессовых воздействий на гидробионтов активно внедряется и имеет большие перспективы в системе мониторинга водных экосистем. В данной работе проанализирована кинетика образования свободных радикалов у различных представителей зообентоса из р. Енисей (амфиподы, олигохеты, пиявки, хирономиды) и амфипод из р. Ус (малая горная река, приток Енисея). Параметры кинетики радикалообразования регистрировали методом люминолзависимой хемилюминесценции при инициировании оксидативного стресса перекисью водорода in vitro в гомогенатах тканей гидробионтов. Выявлено, что у амфипод, в отличие от других беспозвоночных, процесс антиокислительной активности характеризуется двумя вспышками хемилюминесценции. Кроме того, у амфипод наблюдались межвидовые и возрастные отличия по параметрам кинетики генерации свободных радикалов. У Gmelinoides fasciatus Stebb. пик интенсивности генерации свободных радикалов и их общее количество за 60-минутный период регистрации достоверно превосходили данные показатели для Gammarus sp. и Eulimnogammarus viridis Dybowsky. С возрастом наблюдалось увеличение объема продукции свободных радикалов у E. viridis и Gammarus sp. и снижение у G. fasciatus. Отмечено достоверно более высокое значение объема генерации свободных радикалов у G. fasciatus и E. viridis, обитающих в зоне р. Енисей с повышенной антропогенной нагрузкой.
The adaptation of living organisms to the environmental conditions is formed and manifested at different levels - from the molecular to the biocenotic. Nowadays, the metabolic antioxidant system (AOS) is considered to be the key part of adaptive processes, and its activation is regarded as a general response of biota to the negative impact of the environment. The usage of AOS components as biomarkers of stressful influence on hydrobionts has good prospects and is actively applied in the monitoring system of aquatic ecosystems. In this paper the kinetics of free radical formation in various zoobenthos representatives from the Yenisei River (amphipods, oligochaetes, leeches, chironomids) and in amphipods from the Us River (a small mountain river, the Yenisei tributary) is analyzed. Parameters of kinetics of radical formation were registered using the method of luminoldepended chemoluminescence under the initiation of oxidative stress with hydric dioxide in vitro in homogenates of hydrobionts tissues. It was revealed that in amphipodes, as opposed to other invertebrates, the process of antioxidative activity is characterized by two chemiluminescent flashes. What is more, interspecies and age-related differences in parameters of the kinetics of free radicals formation were noticed in amphipodes. In Gmelinoides fasciatus Stebb. the intension peak of the formation of free radicals and their total number during the 60-minute registration period authentically exceeded these parameters for Gammarus sp. and Eulimnogammarus viridis Dybowsky. With age, the increase in volume of production of free radicals in E. viridis and Gammarus sp. and its decrease in G. fasciatus were observed. The authentically higher value of volume of production of free radicals in G. fasciatus and E. viridis inhabiting the zone of the Yenisei River with heightened anthropogenic load was marked.

   Перевод заглавия: Temporal dynamics of structural and functional characteristics of the Yenisei river phytoplankton downstream of the Krasnoyarsk hydroelectric power station
Аннотация: Представлены результаты изучения формирования фитопланктонного сообщества и флуоресцентных характеристик вод в условиях сброса высоконапорной Красноярской ГЭС. Сезонные и межгодовые изменения фитопланктона оценивали на основе численности и биомассы клеток фитопланктона, а также концентрации хлорофилла а. Выявлены закономерности сезонных сукцессий и межгодовых вариаций структурно-функциональных характеристик фитопланктона. Обнаружено, что основу флористического списка в реке Енисей составляют диатомовые водоросли (66% от общего видового состава), преобладающие в планктоне во все сезоны года. Наибольший вклад в общую численность и биомассу фитопланктона вносят нанофитопланктон (2-20 мкм) и микрофитопланктон (20-64 мкм). В комплекс доминантов вранневесенний период входили Diatoma vulgare Bory и Hannaea arcus (Ehrb.) Patr., в летний - Aulacoseira islandica (O. Mull.) Sim. и Cyclotella radiosa (Grun.) Lemm., позднелетний - Fragilaria crotonensis Kitt. Вместе с тем на фоне увеличивающегося видового разнообразия и интенсивного развития водорослей в весенне-летний период отмечен спад концентрации хлорофилла а. Установлено, что во все рассматриваемые годы пики численности и биомассы фитопланктона приходятся на июнь за счет колониальных диатомовых водорослей, попадающих в нижний бьеф со стоком из верхнего бьефа.
The Yenisei River is the biggest waterway in Siberia. In the second half of the 20th century, the Yenisei River was overlapped by dams, and it deeply damaged the natural hydrological, hydrochemical and hydrobiological regimes of the river. As a result of constructing the Krasnoyarsk hydroelectric power station, a significant river component - phytoplankton, which occupies the central place in the formation of the aquatic ecosystem - has changed downstream of the river. In the river, phytoplankton is formed from phytoperiphyton and allochthonous algae, including phytoplankton species of upstream reservoirs. Therefore, knowledge of transformation laws of phytoplankton species composition, which occurs during the regulation of the river flow and formation of reservoirs, may contribute to the development of ideas about changing the aquatic communities. The aim of this research was to explore the formation of phytoplankton under the conditions of water discharge in the Krasnoyarsk HPS and to study chlorophyll a concentration. We collected phytoplankton samples at a distance of 34 km below the Krasnoyarsk HPS (55°59'1.8"N, 92°47'13.4"E) in 2008-2014 and analyzed them according standard hydrobiological methods (See Table). In 2012-2014, we measured fluorescent water characteristics along with the study of algae. We took the nomenclature for algae considering taxonomic transformations according to the system adopted by the International algae database (http://www.algaebase.org). A quantitative processing of phytoplankton samples was conducted daily, species composition and biomass of algae was determined weekly. In size, algae cells were differentiated according to Rainey. The degree of complexity of phytoplankton communities was determined calculating the Shannon species diversity index (by biomass). The dominant algae included species making the main contribution into the total phytoplankton biomass. In 20122014, along with the study of algae, we determined chlorophyll а concentration by fluorimetric method, weekly (See Fig. 3). We collected and processed a total of 2453 qualitative and quantitative phytoplankton samples for the period of study; 89 samples to determine chlorophyll а content. Altogether, we found 99 species, kinds and forms of algae from 6 groups in the river phytoplankton. In the Yenisei River, diatoms, which predominate in plankton in all seasons, are characterized by the maximum number of species. There is a certain sequence in the appearance of dominant algae. From late April to late May, Diatoma vulgare Bory and Hannaea arcus (Ehrb.) Patr. were recorded in quantities, in June -Aulacoseira islandica (O. Mull.) Sim., in July - Cyclotella radiosa (Grun.) Lemm., in August - Fragilaria crotonensis Kitt. (See Fig. 1). Upstream of the Krasnoyarsk reservoir A. islandica had a dominant position in nephotic cold layer in June, in July and August - C. radiosa; F. crotonensis was a subdominant. It is known that deep water discharge through the dam (18-40 м) is specific for the Krasnoyarsk reservoir. This causes the flow of algae over the dam. In general, the dynamics of the total number and the total biomass of phytoplankton had the form of unimodal curve within the year (with a peak in June) (See Fig. 2). Nanophytoplankton (2-20 mkm) and microphytoplankton (20-64 mkm) made the biggest contribution to the total biomass of phytoplankton. We recorded peaks of number and biomass of phytoplankton in June in all years in question. We found that the percentage of chlorophyll content per phytoplankton biomass unit had seasonal variations and increased in winter (See Fig. 5). It is known, that the concentration of chlorophyll a depends on dimensional structure of phytoplankton. In spring and summer, the domination of algae cells with bigger volumes in phytoplankton caused a decrease in chlorophyll а concentration.

   Перевод заглавия: Influence oF Krasnoyarsk hydropower station discharge rate on dynamics of phytoplankton population downstream the dam
Аннотация: В результате многолетних натурных наблюдений определены факты влияния повышенной скорости сброса воды через шлюзы плотины Красноярской ГЭС на динамику фитопланктона р. Енисей ниже плотины. Высказано предположение, что механизм влияния данного фактора заключается в следующем: повышенный сброс воды изменяет температуру воды реки в нижнем бьефе, что в свою очередь влияет на динамику численности фитопланктона. Справедливость данного предположения подтверждается данными 2008-2016 гг. Полученные результаты могут быть применены для составления прогнозов динамики фитопланктона в нижнем бьефе в следующие временные периоды.
Using multiyear measurements, we investigated the influence of high flow rates at Krasnoyarsk hydropower station (Krasnoyarsk HPS) on the phytoplankton population of Yenisei River downstream the dam. We propose the hypothesis that flow rate variations change water temperature, which is influencing the phytoplankton dynamics. This hypothesis is verified by measurements conducted in 2008-2016. The results obtained can be used for the forecast of phytoplankton dynamics downstream the dam.

Аннотация: Рассматривается состояние эндемичных байкальских амфипод в р. Енисей, приводятся результаты экспедиционных исследований. Отмечается факт многоразового увеличения количества амфипод в Енисее после зарегулирования плотиной Красноярской ГЭС.

The purpose. The purpose of the work is the theoretical and practical studies of the possibilities for using the geoinformation web-system modern technologies for improving the efficiency of hydrobiological monitoring, and design of software tools of data presentation and analysis for field research. Methods. The technologies for development of distributed information systems in multi-tier architecture, along with software interfaces and protocols, information exchange standards are considered. The possibilities for using of geoinformation and cartographic modelling methods for searching the relationship between the spatial distributions of Baikal amphipods in the Yenisei river with different environmental factors are investigated. Results. The technologies and related software are developed for the considered problem. The geospatial database is generated and filled with the results of own longterm hydrobiological field studies, it has become an integral part of the geoportal of ICM SB RAS, which was formed by the separate thematic section. The focus is on the results of extensive field studies of the Yenisei implemented in 2015 and 2016. As to database content, the information about the quantitative distribution of zoobenthos (animals inhabiting the ponds bottom), in particular endemic Baikal amphipods, in the area from Yenisei river headwaters to its delta was used. It was revealed that the amphipods - the endemics of the Baikal lake - spread far beyond its limits not only downward, but also upstream the Yenisei river. After the commissioning of the Krasnoyarsk hydroelectric power station, their share in the total zoobenthos biomass is increased by 10 times. Gmelinoides fasciatus crustacean is especially active; it has massively populated the area of the Upper Yenisei river below the Sayano-Shushensky reservoir. The density and the fraction of crustaceans in the zoobenthos in the area of the Angara - Podkamennaya Tunguska has increased over the last 15 years. Conclusions. Creation of a geospatial database alongside with the results of expeditionary research and the introduction of a GIS web-system for information-analytical support of hydrobiological monitoring significantly expands opportunities for the analysis and presentation of geodata, forms the basis for interdisciplinary research.

Аннотация: Представлены результаты экспедиционных гидробиологических исследований, проведённых в 2015-2016 гг. в нескольких зонах русла р. Енисей от истока до устья. Данная работа посвящена про- странственной динамике сообщества амфипод, в котором лидирующие позиции занимают виды - вселенцы из оз. Байкал, распространившиеся через р. Ангару не только вниз, но и вверх по течению р. Енисей. Выявлено 8 видов амфипод, среди них два представителя нативной фауны ( Pontoporeia affinis и Gammarus sp. ) и 6 байкальских эндемиков. На всём протяжении реки среди гаммарид коли- чественно доминировал Gmelinoides fasciatus, второе место занял Philolimnogammarus viridis. Лишь в низовье и дельте Енисея лидирующие позиции перешли к P. affinis - представителю эстуарно- реликтового комплекса организмов, эндемику дельты Енисея. Байкальские эндемики активно засе- лили участок ниже Саяно-Шушенского водохранилища, особенно в зонах массового распростране- ния макрофитов. Основным вектором распространения байкальских эндемиков в Енисее является саморасселение через р. Ангару, замеченное исследователями еще в XIX в. Для G. fasciatus дополни- тельным стимулом роста численности ниже и выше Красноярской ГЭС стала его преднамеренная интродукция в Красноярское водохранилище в конце 1960-х гг. с целью обогащения кормовой базы. Натурализации Ph. viridis на участке Верхнего Енисея способствовала, вероятно, случайная интро- дукция. Наблюдается дивергенция экологических ниш у G. fasciatus и Ph. viridis в Енисее: доминант предпочитает заиленные песчано-галечные биотопы со спокойным скоростным режимом; субдоми- нант склонен к каменисто-галечным грунтам, омываемым быстрым течением. За последние 15 лет возросла плотность и доля амфипод в зообентосе на участке Ангара - Подкаменная Тунгуска. Ре- зультаты гидробиологических исследований оформлены в виде геопространственной базы данных на геопортале, который предоставляет возможности визуализации информации в виде интерактив- ных тематических карт и обеспечивает возможность прямого доступа к данным через картографи- ческие веб-сервисы из современных ГИС.
The results of hydrobiological studies of expeditions, conducted in 2015-2016 in several zones of the Yenisei River from its head to the mouth, are presented. This work deals with the spatial dynamics of the amphipod community, in which the leading positions are occupied by invaders from Baikal. The invaders spread through the river Angara not only downstream, but also upstream the Yenisei. Eight species of amphipods were identified, and there were two representatives of native fauna ( Pontoporeia affinis and Gammarus sp.) and six Baikal endemics among them. Throughout the river, Gmelinoides fasciatus dominated quantitatively among the gammarids, Philolimnogammarus viridis took the second place. Only in the lower reaches and in the delta of the Yenisei the leading positions were surrendered to Pontoporeia affinis - a representative of the estuary-relic complex of organisms. Baikal endemics populated actively the Upper Yenisei section below the Sayano-Shushensky hydroelectric power station (HPS), especially in the areas of massive macrophyte distribution. The main vector of Baikal endemics spreading in the Yenisei is self- colonization through the river Angara, noticed by researchers in the 19th century. For G. fasciatus, its intentional introduction into the Krasnoyarsk Reservoir in the late 1960s with the aim of increasing the food supply was an additional stimulus for the growth of the population below and above the Krasnoyarsk HPS. Naturalization of Ph. viridis in the Upper Yenisei section was probably contributed by an accidental introduction. There is a divergence of ecological niches in G. fasciatus and Ph. viridis in the Yenisei: the dominant prefers silty sand-and-shingle biotopes with a calm speed rate; the subdominant tends to prefer stony-pebble bottom washed by a rapid current. Over the last 15 years, the density and proportion of crustaceans in the zoobenthos have increased in the Angara - Podkamennaya Tunguska section. The results of hydrobiological studies have been designed in the form of geospatial database in the geoportal, which gives the possibility to visualize information as interactive thematic maps and which provides the direct access to data via web mapping services from the modern GIS software.

    Analysis of elastic waves generated in frozen grounds by means of the electromagnetic pulse source "yenisei

Detkov // IOP Conference Series: Earth and Environmental Science : Institute of Physics Publishing, 2018. - Vol. 193: 5th All-Russian Conference with International Participation on Polar Mechanics 2018 (9 October 2018 through 11 October 2018, ) Conference code: 141746, Is. 1, DOI 10.1088/1755-1315/193/1/012058 . -
Аннотация: Computational technology for multiprocessor computing systems of cluster architecture is developed, the ultimate goal of which is numerical modeling of wave fields generated by the electromagnetic pulse source "Yenisei" in blocky-layered geomedia. To describe the wave processes, mathematical models of the dynamics of elastic and elastic-plastic media, of porous and granular materials are applied. The algorithms of numerical realization are constructed based on the method of two-cyclic splitting with respect to spatial variables. Computational experiments showed that the proposed technology allows reproducing the system of waves near the region of excitation of seismic oscillations in 3D setting with a high degree of details and accuracy. The results of computations can be used in working out the optimal modes of functioning the source "Yenisei", when mechanical characteristics of the layers vary in a wide range from solid and frozen grounds with inclusions of rock till granular and clayey water-saturated grounds. Numerical analysis makes also possible to obtain the averaged data, necessary for the adequate simulation of the localized pulse action from the source, using simplified mathematical models for calculating the synthetic seismograms of reflected waves over large scale and at great depth of layers bedding in complex geomedia. © Published under licence by IOP Publishing Ltd.

    Numerical modeling of seismic wave propagation generated by the electromagnetic pulse source in layered medium
/ M. P. Varygina, E. P. Chentsov // AIP Conference Proceedings : American Institute of Physics Inc., 2018. - Vol. 2025: 10th International Conference for Promoting the Application of Mathematics in Technical and Natural Sciences, AMiTaNS 2018 (20 June 2018 through 25 June 2018, ) Conference code: 141497, DOI 10.1063/1.5064919 . -

Аннотация: The processes of seismic waves propagation generated by the non-explosive electromagnetic pulse source "Yenisei" are under investigation. Rheological properties of the layered medium including fractured interlayers are taken into account. For numerical implementation, a computational algorithm based on the space-variable two-cyclic splitting method in combination with monotone finite-difference schemes is developed. Parallel software for the analysis of the fields of velocities and stresses in layered medium is designed. Parallelisation of computations is performed by the CUDA technology for supercomputers with graphical accelerators. The results of numerical computations of seismic waves propagation are shown. © 2018 Author(s).
