Summary: The study found significant changes in water yield in the Upper Brahmaputra River basin during 1982-2013, mainly influenced by climate and cryosphere, with minimal impact from vegetation. Decreased precipitation in recent years has led to a decrease in water yield, but meltwater may alleviate water shortages.

Summary: Analyzing the runoff variation and quantifying the impact of different factors on the runoff in the source area of Lancang River is important for ecological protection and sustainable development. The Budyko method is used to calculate the contribution rate of human and climate factors to the runoff change. Results show a significant decrease in annual runoff at Qamdo hydrological station from 1961 to 2018, with 1966 as the mutation year. Precipitation, potential evaporation, and human factors all contribute to the runoff changes. This study has important theoretical and practical significance for the Lancang River ecosystems.

Summary: The Hanjiang River plays a fundamental role in supporting water supply security in northern China while maintaining the health and stability of ecosystems within the basin. However, the combined influence of climate change and anthropogenic interference has resulted in a significant change in the flow regime of the basin, challenging the sustainability of the river system.

Summary: This study estimated the evolution characteristics of runoff and the underlying surface parameter n in the Kuye River Basin using trend analysis and non-linear regression methods. It also determined the contribution of runoff changes and found that complex human activities were the main reasons for the sharp decrease in runoff. In addition, temperature changes and human activities influenced the underlying surface parameters and ultimately changed the runoff.

Summary: This study investigates the impact of climate-induced changes in vegetation on hydrology and environment in the Jialing River Basin. The results show that climate change will cause increased runoff and nitrogen losses, and decreased sediment discharge and phosphorus losses in the basin. The changes in vegetation, predicted to be promoted by climate change, will have significant effects on the basin. The models used in this study provide useful information for formulating management measures.

Summary: Significant changes in runoff have occurred in many regions in recent decades, and understanding the causes of these changes is crucial for water resource management. A new framework based on the ABCD model was proposed to explicitly identify the effects of climate change and human activities on annual and seasonal runoff changes. The study found that the impacts of climate change and human activities varied among different catchments, and precipitation was identified as the dominant climatic driver.

Summary: This study investigates the factors affecting the changes in water resources in the middle reach of the Jinsha River Basin in the upper reach of the Yangtze River. The results show that climate change and reservoir operation significantly impact the runoff and sediment yield of the basin. The findings provide scientific support for the management of water and sediment resources in cascade reservoir watersheds.

Summary: In recent decades, the Vyatka River basin has shown statistically insignificant changes in water discharge, with a slight increase in spring snowmelt-induced floodwater flow and a significant rise in discharge during warm and cold seasons. The decrease in suspended sediment load and erosion intensity is mainly attributed to increased precipitation, especially heavy rainfall in the warm season, as well as land-use/cover changes following the collapse of the Soviet Union. The most noticeable changes were observed in the agriculturally developed southwest and south parts of the river basin.

Summary: This study used an improved Budyko model to quantitatively assess the effects of climate change and ecological restoration on runoff and sediment change in the Nandong Underground River System. The results showed that climate change was the main factor of runoff reduction, while ecological restoration was the main factor of sediment reduction. This study highlighted the need to pay more attention to the reduction of runoff caused by climate change.

Summary: This study utilized suspended sediment yield field data measured by the national and regional hydrological services to investigate the factors influencing sediment yield in Italy. The research found a wide variation in sediment yield and attributed the marked decrease in sediment yield in Italy to factors such as reduced annual precipitation and forest expansion.

Summary: The study reveals significant changes in runoff and sediment load in the Yangtze River Basin, China, due to human activities and climate change. Human activities are identified as the primary cause of the hydrological regime changes, while climate change has a varying impact on runoff, with some areas experiencing increased runoff. These findings have implications for water resource management and environmental protection in the Yangtze River Basin.

Summary: This study investigates the influence of human-induced climate change on the probability of river flood events and finds that it has increased the likelihood of flooding, particularly in Asia and South America. However, in certain regions of North/South America and Asia, the occurrence of flood events is suppressed by human-induced climate change, possibly due to reduced snowfall.

Summary: The study found that climate change has led to an increase in precipitation and temperatures in the Pulangi River Basin, resulting in higher sediment yield and runoff, exacerbating the threat of floods and soil erosion.
