“…The Xiaolangdi Dam is responsible for approximately 52% of outflow reduction both in a year and outside of the flood season and for approximately 32% of flow increase during the flood season [40]. The study by Luan et al [41] regarding the separation of the impact of the check dam on outflow from climate and vegetation changes on a loess plateau showed that the accumulated value of outflow reduction rapidly grew with an increase in the retention capacities of the dams. The highest importance is obviously credited to reservoirs on large rivers, although, according to Lehner et al [42], smaller reservoirs have a substantial effect on the spatial range of flow changes.…”

Water resources are of elementary economic and environmental importance, and the observed global transformations as well as regional environmental conditions necessitate activities aimed at providing an optimal amount of water at different levels. One such solution is hydrotechnical infrastructure that permits the precise control of the amount of water in the catchment. This paper presents results concerning changes in the water flow in the Główna River in Poland before (1955–1983) and after (1984–2021) the construction of the Kowalski Reservoir. In the former period, there were no changes in water flow, and the obtained results were not statistically significant (p 0.05). In the period after the construction of the reservoir, a decreasing trend in monthly flow was observed in December, April, July, September, and October. Moreover, a decrease in 1, 3, 7, and 90 day maximum flow was observed. For maximum 30 day flow, the changes were below the threshold of the adopted significance level. Moreover, minimum flow in the period after the construction of the reservoir showed no significant decreasing trend. In hydrological terms, the reservoir served its purpose by contributing to the stabilisation of the water flow. This information is important from the point of view of an increase in retention and corresponds with a broader programme conducted in the territory of Poland. In the context of the construction of further reservoirs, it is important to investigate the current range of changes in water circulation for objects of the type already functioning in the environment, constituting an actual point of reference.

Human activities are the main reasons for reducing sediment transport in the Yellow River, with thousands of check dams playing a crucial role. Quantifying the sediment reduction efficiency and analyzing the future development of check dams can help ecological construction and management in the Yellow River basin. This study developed a calculation method for sediment reduction by check dams and calculated the annual sediment reduction, and further estimated the sediment reduction efficiency at different periods. In addition, this study also analyzed the construction intensity and proposed construction strategies of check dams in the Yellow River basin. The results show that from 1952 to 2011, the cumulative sediment reduction of check dams in the middle reaches of the Yellow River was 8056 million tons, the annual sediment reduction varied from 0 to 403 million tons, with a multiyear average of 134 million tons. Among the major tributaries in the middle reaches of the Yellow River, the sediment reduction efficiency of check dams ranged from 0.51% to 76.88% due to the ecological management of slopes and the loss of sediment retention capacity by small‐ and medium‐sized check dams, the sediment reduction efficiency from 1980 to 1999 was higher than from 2000 to 2011. Following the analysis of the suitability of check dam construction, we calculated the potential and intensity of check dam construction in the Yellow River basin. The intensity of check dam construction exceeded 50% in the TDG‐LM region (Toudaoguai hydrological station to Longmen hydrological station) in the middle reaches of the Yellow River. We analyzed the siltation situation of large‐sized check dams and proposed strategies for the construction and management of check dams.
