“…The most intense temperature increase is observed from April to May by more than 7º, then the growth rate drops to 4º in June and 3º in July. August is characterized by a slight decrease in temperature by less than 1º, in September -November its rate increases to 7º for each month [13][14][15][16]. The average annual rainfall in the region is 424 mm.…”

Natural factors play an important role in the formation of the chemical composition and allocation of hydrogeochemical classes of groundwater in the Lower Don basin. The most resistant to human effects are groundwater of Sarmatian complex. The prospect of improving the quality of drinking water supply is associated with the involvement of groundwater in water management, but they are characterized by high hardness. Groundwater is influenced by geology, climate, biology, soil, and etc. Understanding the groundwater regime and pathways is essential because groundwater join and mixes with river water.

“…It should be noted the progressive increase in the groundwater level. Some periods of ground water level stabilization (1988 -1990, 1994 -1996) are noted [13][14][15]. Dynamics of temporary changes in groundwater in southwest of Russia is characterized by a long-term increase in the level.…”

“…Volga River frames itself into the future increase of global river flow as a consequence of climate change; predictions have shown an increase of 4-8% during 2071-2100 [62]. To be more specific, future trends in the area show an increase in precipitation, temperature and in the use and levels of waters in rivers [63]. The cyclic oscillations have occurred in the Volga River basin in the last half-century; this has influenced the water level in the reservoir, and therefore the erosion rates of the shoreline.…”

Over the last decades, the number of artificial reservoirs around the world has considerably increased. This leads to the formation of new shorelines, which are highly dynamic regarding erosion and deposition processes. The present work aims to assess the direct human action along the largest reservoir in Europe—Kuibyshev (Russian Federation) and to analyse threatened cultural heritage sites from the coastal area, with the help of historical maps, UAV (unmanned aerial vehicle), and topographic surveys. This approach is a necessity, due to the oscillating water level, local change of climate, and to the continuous increasing of natural hazards (in this case coastal erosion) all over the world. Many studies are approaching coastal areas of the seas and oceans, yet there are fewer studies regarding the inland coastal areas of large artificial reservoirs. Out of the total number of 1289 cultural heritage sites around the Kuibyshev reservoir, only 90 sites are not affected by the dam building; the rest had completely disappeared under the reservoir’s water. The scenario of increasing and decreasing water level within the reservoir has shown the fact that there must be water oscillations greater than ±1 m in order to affect the cultural heritage sites. The results show that the coastal area is highly dynamic and that the complete destruction of the last remaining Palaeolithic site (Beganchik) from the shoreline of Kuibyshev reservoir is imminent, and immediate mitigation measures must be undertaken.

“…Prolonged periods of drought and low water led to the transformation of the river regime, a decrease in the runoff, deterioration of the ecological state, and a negative affecting the fishery [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Changes in the hydrological regime of rivers and the waterlogging of adjacent territories lead to the degradation of natural associations.…”

Climate change leads to the transformation of the water regime of rivers. This paper examines the changes that occur with the Seversky Donets River in the Rostov region. To assess the influence of meteorological factors, studies of temperature changes (1974 - 2020) and precipitation (2001 - 2020) were conducted. An increase in the average annual (from 8 °C to 9.7 °C) and winter (-5.3 °C to -3.6 °C), spring (8.6 °C to 9.9 °C), summer (20.6 °C to 23.1 °C) and autumn (8.1 °C to 9.3 °C) were revealed. Precipitation data showed multidirectional processes; 2001-2010 were drier (294 mm) than the average (419 m), and 2011-2020 wetter (436 mm). Water flow changes analyse in the River Seversky Donets from 1982 to 2020. The assessment of the influence of hydrometeorological factors on the transformation of river flow is an important aspect. There is a tendency to decrease the average annual expenditure. The highest and lowest annual flow of the river was recorded in the 2000s. The minimum water flow in the river was recorded in 2020 (33.95 m3/s), and the maximum in 2006 (211.2 m3/s). The territory is experiencing high anthropogenic pressure in an arid climate. Significant seasonal changes are characteristic of the water flow in the River Seversky Donets. The maximum impact on changes in water levels in the river is provided by snow nutrition, which is associated with uneven water consumption throughout the year.
