“…Maximum river discharges are usually associated with flood hazard (Shiklomanov et al 2007;Frolova et al 2017). However, tendencies in maximum water level tendency which results in out-of-bank flow does not always correlate with tendencies of maximum discharge in North Caucasus, owing to sedimentation processes and anthropogenic factors (Rets and Kireeva 2010;Frolova et al 2017;Vishnevskaya et al 2016;Kotlyakov et al 2016). Accordingly, changes in maximum river runoff can be referred to as climatic prerequisites of modification of presentday flood hazard.…”

“…In the beginning of the 21 th century frequency and intensity of dangerous hydrological processes in North Caucasus was substantially higher then during the previous years that is usually associated with recent climate change (Frolova et al 2017, Semenov andKorshunov 2008;Bazeluk and Lurie 2014;Rets et al 2016;Rets and Kireeva 2010;Malneva and Kononova 2012;Seynova 2008).…”

Based on observational data from 70 hydrological stations in the North Caucasus an evaluation of present values of mean annual runoff, minimum monthly winter and summer runoff was carried out. Series of maps was drawn. Significant changes in mean annual. minimum monthly and maximum runoff during last decades have been revealed in the North Caucasus. A rise in both amount of water availability and potential natural hazard is characteristic of the most of the North Caucasus that is considered to be caused by recent climate change. Mean annual runoff during 1978-2010 increased compared to 1945-1977 by 5-30 % in the foothills and by 30-70% in the plain area. An increase in winter minimum monthly runoff is as well most intensive in the plain part of study area (>100%). Within the foothills it amounts to 50-100%. In mountainous area long-term oscillation of winter minimum monthly discharge strongly depends on local factors, such as geological structure. The rate of the increase in summer minimum monthly discharge regularly grows from central foothill part of Northern Caucasus (30-50%) to the Western plain territory (70-100%). In Kuban river basin 30% of analyzed gauging stations show positive trend in maximum instantaneous discharge, while 9% negative. On the contrary, in the Eastern part – Terek river basin – negative trend in maximum instantaneous discharge is prevalent: 38% of gauging stations. Positive trend in Terek river basin is characteristic of 9.5% of analyzed gauging stations.

“…3 В то же время в регионах, о которых идет речь, по году в целом осадков выпадает довольно значительное количество, в среднем от 900 до 1500 мм/год. Значительные материальные и трудовые ресурсы ежегодно тратятся на противопаводковые мероприятия [2]. Однозначно стоит вопрос об аккумуляции воды, обильно выпадающей в осенне-зимний период.…”

Purpose: to study the influence of the water head in the upstream and the backwater on the part of the downstream on the seasonal storage dam, built in a mountainous area. Materials and methods: complex geological conditions of anchoring a responsible in terms of safety structure in a mountainous area prompted us to a more detailed study of the issue of its stress-strain state with the ability to offer designers in detail the limits of possible changes in the parameters of the displacement of the seasonal storage dam foundation. The need for the dam construction in the mountainous area is due to several factors. First of all, it is a fundamental need to accumulate water on the Black Sea coast of the North Caucasus, where there is an ever-increasing deficit both for the needs of agricultural producers and for public water supply, while in the autumn-winter period, precipitation falls in the region even in abundance, as it is evidenced by flood control costs. Secondly, the mountainous relief and their gorges is the nature-created volume for water accumulation. Thirdly, the lands of mountain gorges are the most unsuitable for agricultural use lands, in contrast to the lands of the valleys, where reservoirs are currently located. Results: the study of the influence of the water head in the upstream and the backwater from the downstream on the dam was carried out using numerical modeling using the Midas and Maxima software products, which made it possible to cover the entire range of actions necessary for solving such problems. Conclusions: it was found that in the range of backwater changes in the headwater of the dam from 0.6 to 2.8 m, displacements at the dam foundation have extreme values at constant values of the head at the dam of 1.0; 5.0 and 10.0 m. In general, the largest displacement values at the dam foundation are observed at the highest head of the dam in the upstream, equal to 10.0 m.

Большое внимание уделяется оценке и картографированию опасности наводнений [1][2][3][4][5][6][7][8][9], а также определению риска и возможного ущерба от наводнений с использованием современной геоинформационной технологии [10][11][12][13][14][15]. Активное развитие получило геоинформационное моделирование пространственно-временных параметров наводнений с использованием данных дистанционного зондирования [16][17][18][19][20][21].…”
