Summary: Arid areas are highly sensitive to global warming and climate change, which greatly affects the fragile water resources system. This study focuses on the Daihai Lake in China's arid area and uses modeling to analyze the climate-hydrology coupling. The results show significant variations in precipitation and hydrological elements, with human activities playing a major role in the decrease of lake inflow.

Summary: This study focuses on the North and South Sources in the upper stream of Qiantang River Basin, China, and aims to identify the relative contribution of climate change and human activities to runoff variation. The results show that climate change dominated the runoff variation in the North Source, while human activities were the main driver for the South Source. Human-induced effects led to a decline in runoff in the North Source, while it contributed to continuous runoff increase in the South Source. The findings also indicate that runoff change due to climate change is more sensitive to precipitation than potential evapotranspiration.

Summary: Recent changes in the hydrological behavior of natural watersheds pose challenges for water planning under climate change. Future droughts may induce unexpected hydrological responses, and commonly used hydrological models cannot accurately represent these shifts in behavior. It is now necessary for hydrologists to determine the underlying causes of shifting behavior and incorporate more dynamic realism into operational models.

Summary: Climate change and human activities have had significant impacts on flow regimes and riverine ecosystems. Current methods for flow regime attribution using hydrological models often underestimate the effects of simulation errors. This study introduces a flow regime attribution framework that integrates hydrological model error correction to assess the impacts of climate change and human activities.

Summary: This study analyzed the responses of streamflow and baseflow in the Bahe River to climate change and human activities. The results showed a declining trend in hydrometeorological variables in the river basin. Precipitation had a stronger correlation with streamflow compared to baseflow. Human activities mainly affected upstream streamflow, while climate change had a greater impact on midstream baseflow. These findings contribute to our understanding of the response mechanisms of the hydrological cycle in a changing environment.

Summary: In this study, five single-type simulation models were used to simulate runoff and analyze the simulation quality by comparing evaluation indexes with a combined hierarchical structure hydrological model. The results showed that the calculated values of runoff obtained with single-type simulation models were more accurate and stable, and the contribution of meteorological factors to runoff could be described in more detail and with precision.

Summary: An extended Budyko framework is developed to analyze future seasonal runoff variations, combining traditional elasticity and decomposition methods. The study finds that human activities, including inter-basin water transfer and reforestation projects, have a substantial negative impact on seasonal runoff reduction in the upper reach of the Hanjiang River basin in China. Climate change projected by ISIMIP3b will intensify the effects in energy-limited seasons. The performance of the extended Budyko framework is robust, indicating its applicability in exploring future seasonal runoff variations.

Summary: Climate change and human activities are two major factors influencing hydrological processes. In the Hunhe basin in northern China with a semi-arid climate, human activities were found to be the main factor contributing to a decrease in runoff, accounting for over 86.3% of the reduction. Climate change increased winter runoff but decreased summer and autumn runoff, leading to an overall decrease in runoff. There is an increasing severity of hydrological drought in the basin, with climate change accounting for 28.2% of the total impact and human activities accounting for 72.8%.

Summary: This study assesses the impacts of climate change and human activities on runoff patterns in the Du River basin. The results show that human activities are the dominant driver of changes in runoff, with climate change also playing a significant role. The study predicts a continued decrease in runoff due to ongoing and future human activities.

Summary: This study investigated the temporal and spatial variations in frozen soil and its effects on streamflow and soil moisture in the Qinghai Lake Basin. The results showed a decrease in permafrost coverage and degradation mainly at elevations between 3600m and 4200m. Permafrost degradation led to an increase in soil liquid water storage and freezing season runoff.

Summary: The study analyzed the changes in temperature, precipitation, potential evapotranspiration, and snow cover area in the Jhelum catchment area in the Western Himalayas for future bi-decades using different emission scenarios. The results showed an overall increase in temperature, with a decrease in precipitation under RCP 4.5 and an increase under RCP 8.5. The snow cover area exhibited a negative relationship with river runoff.
