APPLICATION OF MULTI-CRITERIA EVALUATION TO IMPROVE THE EFFICIENCY OF THE COMBINED VOLGA ENERGY CASCADE

(STEF92 Technology, 2021-12-20, Alexander Ivanov, Rodney Stevens, Carlos Duque, Onwusameka Ogbowuokara)

Show more

The Volga River is today a cascade of lowland reservoirs. This allows flood prevention, river-sea navigation and hydropower generation. There are also disadvantages, such as the flooding of fertile floodplain lands, a decrease in water quality and drastic algal blooms in the summer season. Due to the problems triggered by the current system, alternative solutions have been proposed that include a decrease in the amount of water stored and a reduction in energy production being, which can be compensated with floati...

(STEF92 Technology, 2021-12-20, Lennart Bornmalm, Rodney Stevens, Alexander Ivanov, Ekaterina A. Mitina, Denis Vasiliev)

Show more

UNESCO’s Global Geopark Network reflects the importance of geo-heritage for society. The wide range of characteristics and the varied connections to the local ecology and culture are significant for their individual management. The aim of this article is to use comparisons between Geoparks as a step toward a generic, conceptual model that can be adapted and used to understand the crucial, functional relationships between system variables and how these variables can be optimized for stainable management. A general ...

MULTI-CRITERIA EVALUATION OF A POSSIBLE GEOPARK AT THE CONFLUENCE OF THE OKA AND VOLGA RIVERS

(STEF92 Technology, 2021-12-20, Alexander Ivanov, Lennart Bornmalm, E. Mitina, D. Malyshev)

Show more

The article includes estimates to confirm that the energy of the water of the Oka and Volga rivers at their confluence has being sufficient to erode transfer the volume of surrounding sedimentary rocks, and forming a height difference of about 100 m between the right and left banks and creating a unique landscape of stunning beauty and attractiveness. This phenomenon is due to the work of the Coriolis force and therefore is ubiquitous. However, at the confluence of the Oka and Volga rivers the transfer of sediment...

MULTI-CRITERIA EVALUATION OF THE VOLGA ENERGY CASCADE

(STEF92 Technology, 2021-12-20, Alexander Ivanov, Rodney Stevens, Carlos Duque Calvache, Onwusameka Ogbowuokara, Ivan Krayev)

Show more

The Volga River is essentially a cascade of reservoirs that provide hydroelectric energy. This technical solution made it possible to produce electricity for industrialization, to ensure the passage of river-sea vessels between five seas and to stop floods on the Volga River. Although often considered a green energy source, there are environmental and economic considerations that should be accounted for in a holistic and sustainable perspective, i.e. a life cycle of ca. 50 years, areal inundation by reservoir wate...

ENVIRONMENTAL RISKS AFFECTING HEALTH AND HERITAGE SITES IN LARGE HISTORIC CITIES

(STEF92 Technology, 2020-09-20, Alexander Ivanov, A. Platov, Ivan Krayev, Д.А. Малышев)

Show more

The goal of the research is to identify the most significant groups of environmental risks for large cities with heritage sites. Along with relatively rare events threatening heritage sites such as karst, floods and landslides, a group of risks associated with fast-paced processes has been identified, with immediate hazardous effects. These are the risk of hypothermia and frostbite, the risk of heat stress, the risk of immediate toxicological effects caused by heavy traffic, the risk of traffic noise and the risk ...

RESEARCH OF PHYTOPLANKTON DISTRIBUTION IN A STRATIFIED RESERVOIR

(STEF92 Technology, 2019-06-20, Alexander Ivanov)

Show more

The goal of integrated multidisciplinary research was to develop a model for estimating and forecasting the dynamics of phytoplankton depending on meteorological and hydrophysical parameters. The analysis of water samples from various horizons obtained in the Gorky reservoir from 2015 to 2018 was performed as an important part of the research. Samples were examined for the presence of algae using a Levenhuk microscope equipped with a digital camera and connected to a computer. The results of the identification of ...

A holistic approach to the design of ecological online services has been developed. The approach is based on the concept of the Internet of Things. Available online data includes local meteorological information and information on GPS coordinates of traffic flows. It allows to calculate in several seconds micro-weather characteristics, parameters of chemical and noise pollution of atmospheric air and parameters of algal processes of lakes and reservoirs. Verification of models of environmental online monitoring is...

BITUMEN DEPOSITS IN THE EASTERN PART OF THE SIBERIAN PLATFORM

(STEF92 Technology, 2017-11-20, Rinat Atlasov, Alexander Ivanov, Maria Nikolaeva, Ewaldt Tugi)

Show more

In order to exclude the unprofitability of heavy oil deposits development in Russia and abroad, it is necessary to search and create new more advanced technologies for heavy oil and bitumen deposits development aimed at improving and creating technologies for increasing oil recovery, which allow developing fields with the greatest economic efficiency. This is due to both the structure of "unconventional" oil reserves and the need for more complete production of hydrocarbon reserves with sufficient high production ...

EXPERIMENTAL RESEARCH ON FORMULATION SOLVENT FOR HEAVY OIL AND NATURAL BITUMEN EXTRACTION IN CRYOLITHOZONE

(STEF92 Technology, 2017-06-20, Alexander Safronov, Maria Nikolaeva, Rinat Atlasov, Alexander Ivanov, Victor Ivanov)

Show more

Some of the most promising areas for the extraction of heavy oil, maltha and asphalt in the eastern part of the Siberian platform are the southern and southeastern slopes of the Anabar anteclise. Using solvents for mining heavy oil and natural bitumen in a permafrost zone is the only option to steam injection, which is obviously cost ineffective there. Advantages of the solvents include convenience of transportation to field and storage stability. Moreover, the solvents have sufficiently high solubility with respe...

Within the eastern Siberian platform are known objects worth mentioning from the standpoint of organizing the extraction of heavy oil and bitumen. The Siberian platform is characterized by a wide spreading of the surface-bearing and shallow-lying rocks saturated with products of hypergenic oil conversion. The article describes the results of lithologic and petrographic studies of bitumen-saturated carbonate rocks of Anabar anteclise southern slope (Daldyno-Alakit region). The upper part of the section of the sedim...

MODEL DEVELOPMENT FOR ONLINE MONITORING OF WATER QUALITY IN THE LAKE TYPE RESERVOIR

(STEF92 Technology, 2017-11-20, Alexander Ivanov)

Show more

Online monitoring of plankton in lake-type reservoirs requires the development of a model which is based on previous information, can assess the current state and predict the concentration of plankton in the future. An improved view of previous periods is possible on the basis of reanalysis techniques. These data can be used as a basis for modeling the profile of wind characteristics and the temperature profile which varies with its influence. A one-dimensional model for lake type reservoir is used in the program ...
