Summary: The hydrological effects of afforestation in different basins across China were explored using hydrologic observations and remote sensing data. It was found that afforestation and reduced precipitation contributed to runoff reduction in cold and dry basins, while afforestation and drying climate induced a significant decrease in runoff in a semi-arid basin. Wet basins showed insignificant changes in total runoff, but an increase in baseflow during dry seasons. The study highlights the long-term variable effects of forest expansion and local climatic variability on basin hydrology.

Summary: This study proposes a semi-automatic method called direction-dominated change vector analysis (DCVA) for detecting from-to information of forest change. DCVA, by determining change directions first and setting different magnitude thresholds for each change type, holds the advantage of accurately detecting different types of forest change. Experiments with Sentinel-2A satellite images demonstrate the effectiveness of DCVA in forest change detection, showing successful extraction of changed areas for four types of forest change.

Summary: Terracing is an effective method for soil and water conservation in sloped terrains. The resolution of the digital elevation model (DEM) used in hydrological models can influence the accuracy of terrain representation and model performance. This study found that DEMs derived from LiDAR data improved the accuracy of terrain representation and increased the accuracy of the SWAT hydrological model in simulating streamflow. Comparing simulations with and without terraces, it was found that the presence of terraces reduced streamflow by 28% to 36%, demonstrating the effectiveness of terraces in water conservation.

Summary: Interception loss is an important part of the hydrological cycle and can be influenced by fire. This study found that fire can alter the process of rainfall partitioning, increasing throughfall rate and decreasing interception loss and stemflow. The revised Gash model can accurately predict rainfall partitioning and interception loss in burned forests. The dominant components of interception loss still come from evaporative processes in the canopy, and the predicted interception loss is highly sensitive to changes in canopy cover, rain intensity, and evaporation rate.

Summary: Vegetation changes, especially due to plant diseases, can have significant impacts on the hydrological cycle. In the northern Rocky Mountains, the invasion of white pine blister rust resulted in the mortality of western white pine and a subsequent shift to shade-tolerant tree species. By analyzing long-term records, researchers found that this vegetation change caused an increase in streamflow over several decades. This study highlights the importance of long-term ecohydrological data and demonstrates how land cover changes can affect hydrological dynamics.

Summary: Climate change has complex and uncertain impacts on the forest-water nexus, inhibiting adaptive forest watershed management. It alters watershed hydrology in various regions and at different scales, with different responses based on tree species, forest types, climate types, and hydrological regimes. Forest changes and management can exacerbate or mitigate the negative hydrologic impacts of climate change.

Summary: The study explores the dynamics of the landscape in the Three Lakes Region of Western Switzerland, with a particular focus on the formation and degradation of mires. Over the past 2000 years, hydrodynamic and geomorphic activities have increased, leading to severe degradation of moorlands, with mean annual carbon losses of 4.9 t ha(-1) in agricultural land and 2.4 t ha(-1) in forests. Forests can limit but not completely stop the degradation of mires, suggesting that agroforestry may be a potential alternative land-use system for sensitive areas in the future.

Summary: The study systematically sampled xylem and phloem water to show that phloem water is significantly less enriched in heavy isotopes than xylem water. The results also revealed a larger isotopic difference between xylem and phloem during phloem water refilling and under periods of tree water deficit. These findings suggest that radial water transport across the xylem-phloem boundary may drive the relative depletion of heavy isotopes in phloem and their relative enrichment in xylem.

Summary: This study evaluates the performance of three different HBV model structures on 14 heterogeneous boreal catchments, showing that the three-bucket structure performs better in larger catchments while a single reservoir structure is sufficient for lake-influenced catchments with lower elevation. Although estimates of mean catchment storage varied between different model structures, the ranking between catchments largely agreed across the different structures.

Summary: This study investigated the ability of the long short-term memory (LSTM) model to predict daily discharge under changing climate conditions in six snow-influenced catchments in Switzerland. The results showed that the LSTM had a better fit than the HBV model during calibration, but its performance dropped considerably during validation. However, using longer time series improved the robustness of the LSTM model. Overall, the HBV model was found to be less sensitive to contrasting climate conditions compared to the LSTM.

Summary: Previous studies on tree water source partitioning have mostly focused on the growing season, leaving little known about the source of tree transpiration before, during, and after snowmelt. This study investigates the water use of boreal forest trees during spring snowmelt, particularly after winter stem shrinkage. The results show that snowmelt is a significant source for stem rehydration and transpiration in the boreal forest during the spring onset.

Summary: In this study, a 98 m soil core from the Loess Plateau of China was sampled and the relationship between pore water isotopic values and hydroclimate history was examined. The results showed that the δO-18 and δH-2 values between 14-50 m were anomalously low, corresponding well to the Little Ice Age period from 1420 to 1870. This identification was consistent with other standard proxies in the region and revealed the temporal dynamics of temperature anomalies. The study highlights the potential of stable isotopes of soil water for paleoclimate reconstruction in deep soils.

Summary: An isotope-enabled module of Hydrus-1D was used to trace the origin and transit time of irrigation water in a glasshouse experiment with a potted olive tree. The soil hydraulic parameters were optimized through inverse modelling, and the model's performance was validated with observed sap flow z-scores and xylem water O-18. The study found that on average, 26% of irrigation water was removed by plant transpiration with a mean transit time of 94 hours, suggesting transit time as a functional indicator for irrigation water uptake in agricultural ecosystems.

Summary: Hydrological catchment models are important tools for water resource management planning. Although computer capabilities have greatly increased, some relatively simple models are still widely used. The HBV model, first applied in Sweden 50 years ago, is a typical example of a conceptual catchment model. The history of model development, from consideration of different model structures to studies using numerous catchments and cloud computing facilities, is described, and the wide range of model applications is discussed.
