Summary: This study evaluated the trends of reference evapotranspiration (ET0) in the Senegal River Basin, finding that regional climate models (RCMs) were more robust than global circulation models (GCMs). ET0 was found to be more sensitive to relative humidity, maximum temperature, and solar radiation, with significant increases projected in ET0, maximum and minimum temperatures in the period 2036-2065.

Summary: This study used the Budyko framework to explore the impact of precipitation and human activities on streamflow variability in the Lancang River Basin. The results showed that the four parametric Budyko equations performed better in reflecting changes in catchment characteristics, and longer baseline periods yielded more reasonable results in attributing streamflow change. The study also found that human activities dominated the streamflow decrease during the transition and impact periods, while climate change further exacerbated the streamflow decrease in LRB.

Summary: This study evaluates the impacts of land use/land cover and climate change on hydrology and soil erosion processes in a humid tropical region in India. Using the SHETRAN model, the researchers compare past land use maps and climate data with future climate scenarios. The results show that land use, climate variability, and combined effects have different influences on streamflow and sediment load. The projections from a general circulation model indicate an increase in temperature, precipitation, streamflow, and sediment load in the future. The SHETRAN model proves to be effective in assessing the impact of climate change on hydrology and sediment yield, providing valuable insights for future river basin management.

Summary: This study focuses on determining trends in precipitation and streamflow series in the Upper Blue Nile River Basin in Ethiopia. The Discrete Wavelet Transform (DWT) and Mann-Kendall test were used to analyze the data. The results show an increasing but insignificant trend in precipitation stations, while streamflow stations exhibit a significant increasing trend. The combined use of DWT and Mann-Kendall test reveals that periodic events up to 4 years have a greater influence on the observed trends.

Summary: This study combines remote sensing and CMIP6 data with hydrological modeling to investigate the impact of climate change on hydrological parameters. Future changes in precipitation and streamflow were projected in the Hongshui River basin, and it was found that climate change contributes 11% to streamflow variability.

Summary: This study investigates the influence of water management on projected changes in streamflow in the Columbia River basin. The results indicate that regulation reduces shifts in winter and summer flows, but amplifies shifts in warm-season and annual high flows. Additionally, regulation reduces changes in dry-season low flows in headwater tributaries.

Summary: This study evaluates the effectiveness of reservoir regulation for changing hydrological extremes in the Lancang-Mekong River Basin in the 21st century. It found that reservoir regulation can mitigate basin-wide dry and wet hydrological extremes, although the lack of reservoir storage capacity presents a challenge for managing wet hydrological extremes in the basin in the future.

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: Climate change significantly affects the hydrological regime, and the integration of climate models with physical based models is crucial for accurate measurement of surface water changes. The study found that the INMCM-4 and MRI-CGCM3 models, as well as their ensemble mean, performed well in predicting rainfall and temperature in the Mahi River basin, India. The findings indicate that there will be an increase in average annual streamflow in the near future.

Summary: The study reveals that the streamflow in the Yellow River Basin is significantly decreasing, mainly due to human activity, with climate change playing a relatively smaller role in the reduction. This finding is crucial for water resource management in the Yellow River Basin.

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.

Summary: Climate change is a significant factor affecting water supply in semi-arid and arid areas such as Iran. This research investigates the impact of climate change and upstream land use on the Tajan River in northern Iran. The study shows that peak streamflow will increase by 4% and 5.7%, while average annual discharges will decrease by 16% and 16.5% from 2016 to 2066 under different climate scenarios. Furthermore, different land use change scenarios lead to an increase in average annual streamflow by 8.5-15.8%. It is concluded that downstream water users should implement strategies to cope with the changing climate and water scarcity.

Summary: The study investigates and reconstructs the historical hydroclimate variability of the Karnali River catchment in Nepal. The findings reveal past pluvial and low-flow periods, as well as an increasing frequency of extreme low-flow and pluvial events in the recent century. The study also identifies periodicities in the streamflow series that are teleconnected with climate modes like ENSO and PDO. The research provides valuable insights for water resource management and policies amidst current and future climate change.

Summary: The study reveals that in the future, the temperature in Southeast Asia will increase and annual precipitation will decrease, especially in the Mun River Basin after 2020. Projections suggest that streamflow in the Mun River Basin will gradually increase over the following decades, particularly during the wet season months.
