The processes of formation and distribution of the resources of fresh groundwater and surface water in the territory of Crimea Peninsula are considered. Water availability in the natural–historic and administrative regions of the republic is characterized. The proportions between different categories of groundwater resources are shown with their role in water supply to Crimea taken into account. The presentday development of groundwater resources is analyzed and the possible increase in water consumption meeting geoecological requirements is substantiated. 相似文献

The formation and distribution of present-day water resources under the effect of changing climate are studied. Seasonal, annual, and many-year variations in the regime of spring-flood and dry-season runoff of rivers with drainage areas from 2000 to 20000 km2, reflecting the zonal landscape-climatic conditions of runoff formation, are considered. It is shown that various and often contradictory demands of water users to water supply distribution over seasons of the year result in that the entire water management complex depends on not only the total volume of water resources, but also on the water regime characteristics of rivers in different phases of hydrological year. It was established that the climate changes recorded in the recent decades radically change the pattern of space and time variations in runoff characteristics. 相似文献

The role of bogs as filters on the path of pollutant migration to surface and subsoil waters is demonstrated. Sorption hysteresis is shown to play a major role in the retention of pollutants by peat mass. The mathematical problem of pollutant transport and absorption in bogs is formulated and solved numerically.Translated from Vodnye Resursy, Vol. 32, No. 2, 2005, pp. 205–213.Original Russian Text Copyright © 2005 by Belyaev, Dzhamalov, Krichevets, Polyakova, Yushmanov. 相似文献

The dynamics of natural recovery of bog massifs in Tver oblast, which suffered from fire in 2010, is discussed. The presented conclusions are based on three-year field observations at check sites of Galitskii mokh bog along with monitored variations of the physicochemical properties of peat ash and pyrolyzed peat, bog water chemistry, the development of microbial communities, and vegetation recovery. Moreover, some features of bog massif flooding are discussed. 相似文献

Variations in the characteristics of the annual, dry-season, and minimal monthly runoff in rivers of European Russia for the recent 35 years (1975?C2005) have been estimated and analyzed in comparison with a period of approximately the same duration (1935?C1969). The genesis of runoff for different river basins and the major causes of current changes in runoff characteristics have been studied. Regional regularities in the hydrological and geohydrological processes have been identified, and zoning of the territory has been performed with identification of specific features in the formation of river runoff in the European North and the basins of the Volga, Don, Ural, etc. The natural resources of surface and subsurface waters over 1970?C2005 have been re-estimated with the construction of appropriate maps. Water availability and load on water resources have been analyzed. 相似文献

Analysis is given of a relatively new method for studying the distribution and dynamics of land water resources, which is based on measuring the anomalies of Earth gravity field with the use of GRACE satellite system. The international satellite experiment on determining the gravity and climate changes has been carried out since 2002 with the aim of making high-frequency (within the frequency range of 10900?C36000 GHz) measurements of time variations in Earth??s gravity field. The measurement method and the procedure of data processing and evaluating the hydrological-geohydrological characteristics of large river basins and regions based on GRACE data. 相似文献

The natural-climatic causes of changes in river runoff and seasonal recharge of groundwater in Don basin are considered. Joint
analysis is made of changes in the statistical characteristics of the series of air temperature and precipitation, mean annual
and dry-season-averaged runoff for both the entire observation period and of periods 1940–1969 and 1970–2000 with comparable
durations. The presence of statistically reliable ascending trends in air temperature, precipitation, and dry-season (groundwater)
runoff for period 1970–2005 is demonstrated. Climatic changes in Don basin also have their effect on the formation of extremely
low water in small and medium rivers, including cases of zero runoff. Zoning of the territory by runoff formation conditions
is carried out, and new estimates of natural groundwater resources in Don basin for period 1970–2000 are constructed. Appropriate
maps are compiled. 相似文献

The study is focused on the specific features of water resources formation in Eastern Siberia under variable climate and regional occurrence of permafrost rocks. Expert estimates are given to the effect of greenhouse gas emissions on climate evolution in this large region. Under present-day climate conditions, featuring temperature rise and some increase in precipitation as resource-forming factors, the most significant changes are shown to have taken place in the formation of water resources and regime of dry-season runoff in individual rivers of Eastern Siberia, including the Lena, Indigirka, Kolyma, etc. Present-day resources of surface water and groundwater resources in the region are mapped and the dynamics of the annual and dryseason runoff of the rivers are plotted. 相似文献
