Summary: The study utilized SDSM and SWAT models to evaluate the impact of the Fukushima accident on the hydrological processes in HRW, indicating that future climate change will lead to a decrease in annual precipitation and evapotranspiration, with a slight increase in spring. The climate-sensitive RCP8.5 scenario consistently generated larger magnitudes of climatic variables and water balance components compared to other scenarios.

Summary: Climate change has affected hydrological processes and redistributed water resources. This study used the SDSM model, BMA method, and QM method to downscale and correct climate data in the Yongding watershed. The results showed an upward trend in temperature, precipitation, and runoff under future climate scenarios, suggesting a potential alleviation of water shortage in the watershed. These findings are of great importance for decision-making in water resources management and protection.

Summary: The study aims to analyze future drought characteristics in the Kessie watershed, upper Blue Nile Basin, under the impact of climate change. Three drought indices were used: Reconnaissance Drought Index (RDI), Streamflow Drought Index (SDI), and Agricultural Standardized Precipitation Index (aSPI). The results indicate that the research area will experience high magnitude and increasing frequency of meteorological, agricultural, and hydrological droughts, with a stronger association between hydrological and agricultural droughts as the accumulation period lengthens.

Summary: This study investigated the impact of anthropogenic activities on the environment in the Ashi watershed of northeast China, predicting the effects of land use/land cover changes on hydrological processes in 2030 under different scenarios. The results indicate that urbanization and agriculture expansion have significant impacts on water resources and hydrological balance. It is recommended to regulate urban sprawl and agricultural activities to maintain hydrological balance in the watershed.

Summary: This research utilized remote sensing technology to analyze historical trends and predict future changes in land use, land cover, and climate. The findings reveal an increasing built-up area, decreasing vegetation, and rising land surface temperature in the Multan region. This study underscores the importance of remote sensing technology in understanding past and predicting future land transformations and temperature variations, providing valuable insights for decision makers in sustainable land use and climate adaptation.

Summary: The upper Yellow River Basin (UYRB) plays a crucial role in the freshwater supply of the Yellow River. Research shows that while there will be continuous wetting and vegetation greening in the UYRB in a future with warmer temperatures, the impact on hydrological drought changes remains uncertain due to interactions between climate change, land cover change, and reservoir operations. A study using the CSSPv2 + Reservoir model reveals that increased precipitation during dry seasons can reduce the duration of hydrological droughts at different warming levels, but the severity of droughts is limited. However, a significant increase in leaf area index under higher warming levels intensifies evapotranspiration and exacerbates drought severity. Furthermore, reservoir operations aimed at stable hydropower generation can decrease drought duration but increase drought frequency and severity, highlighting the need for a balance between hydropower generation and drought mitigation in future reservoir operations.

Summary: This study examines the impacts of climate change and human activities on hydrological drought in the Hanjiang River basin. The results show that both climate change and human activities exacerbate the severity of hydrological drought, with climate change playing a dominant role in the 1990s. However, human activities have gradually surpassed the impact of climate change on hydrological drought since the 21st century. Reservoir regulation can extend the duration and severity of drought but mitigate the peak. These findings provide valuable information for drought management and water resource regulation in changing environments.

Summary: This study used the SWAT model to investigate the effects of climate change on runoff in the Alvand mountain basin in Iran. The results showed that future climate conditions would lead to an increase in temperature and a decrease in rainfall, resulting in a significant reduction in runoff. Additionally, the study found that the intensity of drought would increase under all scenarios.

Summary: Land use change has a significant impact on the runoff characteristics of the basin, with different land use types showing varying hydrological responses. However, the impact on annual runoff is minimal. Returning farmland to woodlands and grasslands promotes groundwater recharge and plays a positive role in ecological restoration in the basin. These findings are of great importance for understanding the hydrological consequences of land use change and for the rational planning of land use patterns in river basins.

Summary: This study assesses the impact of climate change on hydrological variables in the Bharathapuzha river basin in southern India. Five global circulation models were used to simulate future scenarios, and the SWAT hydrological model was employed for continuous simulation. The results indicate that rainfall, evapotranspiration, soil moisture, and surface runoff are projected to increase in the future.
