“…Research indicates that the average threshold year for flow variability in Eastern Europe is 1978, which closely aligns with our study's findings [68]. Furthermore, 1977 marks a significant turning point delineating a transition between a period of relatively undisturbed natural conditions in the basin and a time when human activities and climate change intensity became more pronounced [69].…”

Climate warming globally has a profound effect on the hydrological regime, amplifying evapotranspiration and precipitation and accelerating the processes of snow melt and permafrost thaw. However, in the context of small river basins—those encompassing less than 10,000 km2—the response of the hydrological regime to climate change is intricate and has not yet been thoroughly understood. In this study, the Zhizdra River Basin, a typical small river basin in the eastern European plain with a total drainage area of 6940 km2, was selected to investigate the long-term variability of the hydrological regime and its responses to climate warming. Our results show that during the period of 1958–2016, the average runoff in the Zhizdra River Basin was approximately 170 mm, with significant fluctuations but no trend. Sensitivity analysis by the Budyko framework revealed that the runoff was more sensitive to changes in precipitation (P) compared to potential evapotranspiration (E0), implying that the Zhizdra River Basin is limited by water availability and has a slightly dry trend. A comprehensive analysis based on the seasonality of hydrometeorological data revealed that temperature predominantly affects spring runoff, while P mainly controls autumn runoff. Both factors make significant contributions to winter runoff. In response to climate change, the nonuniformity coefficient (Cv) and concentration ratio (Cn) of runoff have noticeably declined, indicating a more stabilized and evenly distributed runoff within the basin. The insights gleaned from this research illuminate the complex hydrological responses of small river basins to climate change, underlining the intricate interrelation among evapotranspiration, precipitation, and runoff. This understanding is pivotal for efficient water resource management and sustainable development in the era of global warming.

“…In areas of seasonally frozen ground, surface water-groundwater interactions are primarily modulated by the seasonality of groundwater recharge and subsequent discharge into the surface water network (26,39). For instance, a reduction in seasonal freeze depth, due to the rising winter soil temperature, favors infiltration of melting water that can ultimately reach the underlying aquifer (18,40). This then increases deep flow as well as early and late season groundwater discharge (26).…”

Global climate warming disproportionately affects high-latitude and mountainous terrestrial ecosystems. Warming is accompanied by permafrost thaw, shorter winters, earlier snowmelt, more intense soil freeze-thaw cycles, drier summers, and longer fire seasons. These environmental changes in turn impact surface water and groundwater flow regimes, water quality, greenhouse gas emissions, soil stability, vegetation cover, and soil (micro)biological communities. Warming also facilitates agricultural expansion, urban growth, and natural resource development, adding growing anthropogenic pressures to cold regions’ landscapes, soil health, and biodiversity. Further advances in the predictive understanding of how cold regions’ critical zone processes, functions, and ecosystem services will continue to respond to climate warming and land use changes require multiscale monitoring technologies coupled with integrated observational and modeling tools. We highlight some of the major challenges, knowledge gaps, and opportunities in cold region critical zone research, with an emphasis on subsurface processes and responses in both natural and agricultural ecosystems. Expected final online publication date for the Annual Review of Environment and Resources, Volume 46 is October 2021.

“…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.
