“…According to World Meteorological Organization [32] recommendations «Climatological standard normals: Averages of climatological data computed for the following consecutive periods of 30 years» and the period from 1961 to 1990 has been retained as a standard reference period for long-term climate change assessments. Similar patterns are noted in the work [23] which state that: "The highest reductions of flow appear in the wetter northern basins". The authors also point to a decrease in runoff and significant changes in its intra-annual distribution.…”

Warmer climate caused a large complex of effects that appeared in every link of the global hydrological cycle. In most cases, these changes have a non-linear nature and occur with different intensity in hydrological and meteorological systems. Therefore, it is important to study such processes together, which will allow simultaneous detection of their mutual effects. The water balance method, when all components are calculated in the same dimensions (mm), and then compared with each other, is best suited for solving such a problem. The increase in air temperature by 1,2°C caused significant changes in the overall structure of the Horyn River basin water balance: an increase in the expenditure parts uncertainty for the water balance components for the modern period 1991-2020. The closure error increase occurs mainly due to the cost part and its main component of total evaporation. According to Mali Vykorovychi hydrological gauge notes a decrease in the annual precipitation by 18 mm, river runoff by 21 mm, and an increase in total evaporation by 35 mm in absolute values. In the 1961-1990 according to the calculation of climatic water balance, the moisture accumulation prevailed over its utilization almost in 5 times but now, due to the increase in air temperature, their ratio has almost leveled off. Today river water regime almost moved from the excessively moistened to sufficiently moistened, and there are trends indicating the moisture consumption processes dominance in the basin over its accumulation.

“…Previous studies have shown that global runoff has increased over the 20th century [5]. However, river flow has decreased significantly in many basins worldwide, such as the Spanish basins [6], the Lake Issyk-Kul Basin [7], East African basins [8], as well as some basins in China, such as the Yellow River Basin [9] and the Shiyang River Basin [10], especially in arid and semi-arid regions [11,12]. The continuing decline in runoff has caused a severe water crisis and ecosystem imbalance, threatening the high state and sustainable development of the economy and society [13].…”

Abrupt runoff reduction in the Wei River Basin (WRB) has attracted extensive attention owing to climate change and human activities. Nevertheless, previous studies have inadequately assessed the respective contributions of climate variability and human activities to runoff change on different spatial scales. Using Mann–Kendall and Pettitt’s methods, this study identified long-term (1970–2018) changes in hydro-meteorological variables. Furthermore, the Budyko-based method was used to quantify the influence of climate change and human activities on runoff change at different spatial scales of the WRB, including the whole WRB, three sub-basins, and sixteen catchments. The results show that a significant decrease trend was identified in runoff at different spatial scales within the WRB. Runoff in almost all catchments showed a significant downward trend. Temperature, potential evapotranspiration, and the parameter n showed significant increases, whereas no significant trend in precipitation was observed. The change in runoff was mainly concentrated in the mid-1990s and early 2000s. Anthropogenic activities produced a larger impact on runoff decrease in the WRB (62.8%), three sub-basins (53.9% to 65.8%), and most catchments (–47.0% to 147.3%) than climate change. Dramatic catchment characteristic changes caused by large-scale human activities were the predominant reason of runoff reduction in the WRB. Our findings provide a comprehensive understanding of the dominate factors causing runoff change and contribute to water resource management and ecosystem health conservation in the WRB.
