Regularities in the Spasmodic Development of Deltas
Water Resources - Tập 48 - Trang 897-904 - 2021
M. V. Mikhailova
Regularities of spasmodic delta formation, a rare type of the process, accompanied by breakthroughs and radical transformations of delta hydrographic network, are discussed. The physical prerequisites of this type of delta development are identified; a new scheme of process development and its new division into stages are proposed. Examples are given.
The Regime of Water and Chemical Runoff in the Upper Volga Basin under Global Warming
Water Resources - Tập 45 - Trang 35-43 - 2018
R. G. Dzhamalov, O. S. Reshetnyak, T. I. Safronova, K. G. Myagkova, K. G. Vlasov
The present-day conditions of the formation and distribution of the water resources and chemistry under global warming during the recent decades have been considered. The variations in the characteristics of river water and chemical runoff in the upper Volga basin have been estimated and analyzed. The regional features in the formation of river runoff and water quality variations in 1990–2015 have... hiện toàn bộ
Factors and Processes of Salt Lake Formation on Baikal Shore
Water Resources - Tập 48 - Trang 273-284 - 2021
A. M. Plyusnin, A. V. Ukraintsev, M. K. Chernyavskii, E. G. Peryazeva, N. A. Angakhaeva
The article considers the conditions under which the water resources and chemistry are forming in the mineral Bormashovoe Lake, which lies on the Svyatoi Nos Peninsula on the eastern coast of Lake Baikal. The study was focused on water and free gas, which releases from bottom deposits and lakes in the Svyatoi Nos Peninsula. The results represent the analysis of water samples taken in ice-free and ... hiện toàn bộ
Spatiotemporal variability of algae in monitoring aquatic environment in the Panjiakou Reservoir (Northern China)
Water Resources - Tập 43 - Trang 690-698 - 2016
Jianhua Wang, Yuyan Zhou, Weihua Xiao, Yaohuan Huang, Yanjie Bi, Liting Wang, Zefan Yang
The spatial and temporal variations of algae within a large drinking water reservoir with mesotrophy (Panjiakou Reservoir, Northern China) were investigated in relation to variations in environmental factors over a 6-month period (May to October) in 2013 and 2014. The analysis based on in-situ samples upstream to downstream (Puhekou, Jiajia’an, Yanziyu Panjiakou and Baqian) showed that three harmf... hiện toàn bộ
Analysis of errors in estimating changes in water body areas by satellite data: Case study of thermokarst lakes in Yamal Peninsula
Water Resources - Tập 44 - Trang 180-191 - 2017
S. G. Kornienko
Errors in the estimates of changes in the area of individual water bodies and their groups have been studied in the central part of Yamal Peninsula based on Landsat satellite imagery. For the first time, the overlap zone of two satellite images along satellite trajectory has been proposed for the choice of the most efficient algorithm for identifying water surfaces and estimating the errors in wat... hiện toàn bộ
The status of transboundary rivers in Turkey

Methods of the Theory of Water Flow in Porous Media in Problems Arising in Bog Watering
Water Resources - Tập 45 - Trang 532-541 - 2018
A. Yu. Belyaev, G. N. Krichevets, N. P. Akhmet’eva
The analysis of hydrogeological problems arising in bog watering by methods enabling the depth to groundwater table to be controlled was used to develop a method for estimating the efficiency of such control when data for directly solving groundwater flow problems are lacking. The effect of nonmonotone dependence of the rate of groundwater level rise on the hydraulic conductivity of peat underlain... hiện toàn bộ
Anthropogenic transformations of the Arctic ecosystem of Lake Imandra: Tendencies for recovery after long period of pollution
Water Resources - - 2009
T. I. Moiseenko, N. A. Gashkina, A. N. Sharov, O. I. Vandysh, L. P. Kudryavtseva
Transformation of an Arctic aquatic ecosystem (a case study of Lake Imandra) under the impact of a mining industrial complex is considered. Water chemical composition and the ecosystem’s structural components (phyto- and zooplankton, zoobenthos, and ichthiofauna) are analyzed for the following periods: the preindustrial background (reference) conditions, industrial development of mineral resources... hiện toàn bộ
Natural and Anthropogenic Variations of the Concentrations of Iron, Copper, and Zinc in Water Streams of the Republic of Bashkortostan
Water Resources - Tập 45 - Trang 873-886 - 2018
T. B. Fashchevskaya, Yu. G. Motovilov, N. B. Shadiyanova
The natural and anthropogenic sources of iron, copper, and zinc in water streams in the Republic of Bashkortostan are considered. Statistical analysis of long-term hydrochemical monitoring data was used to establish the spatial year-to-year and annual regularities in metal concentrations in water streams. The acceptability of river water quality for different types of water use was estimated. The ... hiện toàn bộ
