Summary: This study analyzes the impacts of long-term precipitation and land use change on the annual surface runoff in Liuxihe River Basin. The results show that human activities and increased precipitation have both contributed to a significant increase in runoff, with the conversion of croplands to constructed lands being equally responsible as precipitation. Moreover, the study discusses the influence of surface water area, particularly ponds, on peak flow during rainstorms, suggesting it as an important measure for flood mitigation.

Summary: This study investigated the spatially organized links between river runoff time series and climate variability indices, concluding that ENSO is the primary determinant. Machine learning approach, particularly convolution neural network, was found to model river runoff better than traditional baseline methods.

Summary: The study focused on the potential impacts of climate change on river flows in Northern Ireland and surrounding sub-catchments, using a grid-based hydrological model. Results showed possible future decreases in spring-autumn mean flows, especially in summer, and increases in winter mean flows. Additionally, there were projected reductions in 10-year return period low flows and increases in high flows for some locations.

Summary: The climate sensitivity and radiative climate feedback of Earth vary over time due to changing surface warming patterns, which are influenced by the Atlantic meridional overturning circulation (AMOC). This study examines two groups of members from climate model experiments and finds significant differences in the AMOC response to increased CO2 concentration. It suggests that the AMOC plays an important role in setting surface warming patterns, particularly in the Northern Hemisphere extratropics.

Summary: The increase in sediment and nutrient loads from land use practices threatens the Great Barrier Reef. This study reconstructs sediment fluxes using coral records and reveals a tripling of sediment loads since European settlement, indicating an extreme degradation of river catchments.

Summary: Understanding the response of historical extratropical cyclone tracks to global warming is important for predicting future storm activity. This study analyzes long-term data sets and finds that the intensity of extratropical cyclones has increased, along with an increase in North Pacific storm frequency and precipitation and wind gusts in North Atlantic storms.

Summary: The study aims to characterize dry spells and extreme drought events in the Amazon River Basin (ARB) from 1901 to 2018. While a weak basin-wide drying trend was observed, there was no evidence of a trend in extreme drought events. However, a transition to drier-than-normal conditions has been evident since the 1970s.

Summary: Warming in mountainous areas has elevation dependence and impacts runoff change. The Urumqi River Basin showed significant warming, especially in winter. Glaciers sharply retreated, leading to changes in glacial meltwater runoff.

Summary: This study assessed the climate change impacts on the Kara River watershed in northern Togo using sixty years of rainfall data from six measuring stations. The results showed significant spatiotemporal variability of rainfall and aquifer recharge, with a decreasing tendency upstream and an increasing one downstream.

Summary: Taiwan is facing severe disasters such as droughts and floods. Studying the hydrologic response characteristics is crucial for understanding catchment behavior and evaluating river's ability to maintain streamflow. This study divided water flow into four components: fast runoff, intermediate interflow, slow runoff, and dry weather flow, providing a more realistic presentation of the rainfall-runoff process. Results showed that baseflow consisted of intermediate interflow, slow runoff, and dry weather flow. Rainfall intensity was found to be the most important factor affecting streamflow composition. These findings are valuable for establishing rainfall-runoff models and guiding sustainable water resource management.

Summary: This article quantitatively analyzes the impact of vegetation restoration and climate variation on runoff in the Luan River Basin from 1982 to 2018. The results show that vegetation restoration leads to a decrease in runoff, and both the vegetation index and Budyko parameter have a significant influence on the reduced flow.

Summary: This paper investigates the future runoffs of the headwaters of the Tarim River Basin and finds that temperatures are projected to increase and precipitation is expected to increase, especially in the summer. This will pose challenges in flood risk management.

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.
