Space and time analysis of the formation of spring overland runoff in forest-steppe and steppe regions of the Russian Plain has been carried out. It has been shown that, in addition to zonal climate conditions, its distribution over the area is largely determined by the agricultural load on river catchment areas, primarily, the structure of agricultural lands—the proportions of areas under winter tillage and consolidated tillage. The character of overland runoff response to present-day climate changes and agricultural activity has been identified, and quantitative estimates have been given to the manifold hydrological role of these factors. 相似文献

An algorithm has been proposed for assessing the hydrological role of the main anthropogenic factors governing the formation of Moskva R. runoff both separately and in total. The effect of landscape transformations, hydroengineering structures, and water use on the runoff in the Moskva R. basin has been analyzed for characteristic periods in the recent 150 years (the middle XIX century, the early XX century, 1960–1980, and the first decade of the XXI century, the period of calculation of the average long-term runoff). The main hydrological effect of urbanization in the Moskva R. basin on river runoff formation in recent decades has been demonstrated. The shares of the anthropogenic and climatic factors in the overall changes in Moskva R. runoff in the early XXI century have been evaluated. 相似文献

A scheme of water balance differentiation of a territory is proposed. The vertical and space-time structure of water balance are considered. A procedure for regional space-time analysis of water balance was developed and tested, allowing one to evaluate its different characteristics and relationships, to simulate the series of their mean annual values in points where no observations are available, and to carry out computeraided mapping of the obtained results. Electronic maps were constructed to characterize the distribution of river runoff and its surface and subsurface components over the European Russia, the correlation and conjunction between them, the distribution of annual precipitation, and the precipitation of the warm and cold periods over the territory. Statistical relationships, reflecting different aspects of space-time variations in the major water balance elements, are given. 相似文献

The causes of the failure of various dams, the existing approaches to determining the parameters of flood waves caused by dam failures, and the authors' method of calculation of these waves are considered. Characterization of the consequences of the dam-failure flood wave in the tailwater pool of the Volgograd hydroelectric station and some unfavorable aspects of possible evacuation of the Saratov reservoir are presented. 相似文献

Based on the methods of O.I. Krestovskii and recent information on the forestry of European Russia, the article offers the assessment of the impact of transformations in the structure of forests in the recent decades on the river runoff and evaporation. The accompanying changes in the runoff are shown to be relatively insignificant; however, in the XXI century they may become more significant and manifest themselves not only at the local but also at the regional level. 相似文献
