Summary: This study investigates the impacts of different potential evapotranspiration (ETp) inputs on runoff simulation and projection. The XAJ model is used to project runoff in the North Johnstone catchment, northeast Australia. The study finds that future climate scenarios will lead to a significant decrease in spring and winter runoff, mainly due to a decrease in rainfall. The uncertainty in runoff projection is primarily caused by global climate models (GCMs) and their interaction with different representative concentrative pathway (RCP) scenarios.

Summary: This study examined the decline of wetlands in Iran and found that non-climatic factors, particularly changes in land use and land cover, had a greater impact than climate change. The analysis also revealed that the increase in evapotranspiration and decrease in runoff were the main drivers of wetland decline.

Summary: The Arkansas River and its tributaries play a crucial role in providing water resources for agriculture, hydropower, and public water supply in the Arkansas River Basin. However, climate change and other environmental factors have significantly impacted the hydrological processes in the region, leading to ecological and economic consequences. This study used a process-based model to project future river flow patterns in the ARB under different climate and socio-economic scenarios. The results indicated a decline in river flow, with warming and drying climates accounting for the majority of the reduction. The study provides valuable insights into the spatial patterns of water availability changes and the underlying mechanisms, which are essential for developing effective management strategies and mitigating the adverse impacts of climate change on water resources.

Summary: Based on satellite observations and model outputs, this study finds a global increase in vegetation growth and a decrease in terrestrial water storages across drylands from 1982 to 2016. The negative correlation between terrestrial water storages and vegetation growth is especially pronounced in cropland-dominated regions and when vegetation productivity increases. The reduction in terrestrial water storage is primarily driven by precipitation and evapotranspiration variability, rather than runoff.

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: The study reconstructs a high-quality daily runoff time series of Lake Como inflow and outflow in the Adda river basin for the period 1845-2016. Analysis indicates that while there is a non-significant decrease in annual precipitation, annual runoff volumes are decreasing, primarily due to anthropogenic factors such as water abstraction for irrigation and increased evapotranspiration losses caused by natural afforestation.

Summary: The study investigated the impacts of climate change on groundwater recharge in Minnesota using climate models under different emissions scenarios. Despite projections of higher precipitation, overall recharge is expected to decline due to warming-induced evapotranspiration increases. However, soil moisture limitations in drier regions may help buffer the decrease in recharge.

Summary: A water balance model was used to evaluate trends and spatial patterns in Actual Evapotranspiration (AET) and Climatic Water Deficit (CWD) across the Continental United States. The study found increasing drought and decreasing AET in the western US, with opposite trends in the eastern US. When limitations on plant performance due to AET and CWD are exceeded, vegetation assemblages change.

Summary: ET0 in the Tarim River basin exhibited a decreasing trend on an annual timescale, mainly driven by a decrease in summer, while increasing trends were observed in other seasons. Climatic factors such as maximum temperature, relative humidity, and wind speed had significant effects on ET0, with wind speed playing a key role in inducing changes in ET0 in the TRB.

Summary: The contribution of greening to evapotranspiration (ET) in Siberia has been revealed using the Penman-Monteith-Leuning (PML) model. Greening was found to be the major driver of ET variations, accounting for 37% of the variations. Surface net radiation (Rn) and wind speed (Um) also had significant effects on ET, contributing 33% and 19% to the variations, respectively.

Summary: Significant changes in runoff have occurred in many regions in recent decades, and understanding the causes of these changes is crucial for water resource management. A new framework based on the ABCD model was proposed to explicitly identify the effects of climate change and human activities on annual and seasonal runoff changes. The study found that the impacts of climate change and human activities varied among different catchments, and precipitation was identified as the dominant climatic driver.

Summary: Machine learning algorithms have shown better performance in streamflow prediction compared to traditional hydrological models. In this study, researchers proposed a methodology to test and benchmark ML algorithms using artificial data generated by physically-based hydrological models. They found that deep learning algorithms can correctly identify the relationship between streamflow and rainfall in certain conditions, but fail to outperform traditional prediction methods in other scenarios.

Summary: Combined sewer overflows pose significant threats to public health and the environment, and various strategies have been proposed to mitigate their adverse effects. Smart control strategies have gained traction due to their cost-effectiveness but face challenges in balancing precision and computational efficiency. To address this, we propose exploring machine learning models and the inversion of neural networks for more efficient CSO prediction and optimization.

Summary: This study developed a N-cycling model for lowland rural rivers covered by macrophytes and investigated the N imports, exports, and response to sediment dredging. The findings showed a considerable N retention ability in the study river, with significant N imports from connected rivers and surrounding polders. Sediment dredging increased particulate nitrogen resuspension and settling rates, while decreasing ammonia nitrogen release, denitrification, and macrophyte uptake rates.

Summary: High-resolution climate data is crucial for predicting regional climate and water environment changes. In this study, a two-step downscaling method was developed to enhance the spatial resolution of GCM data and improve the accuracy for small basins. The method combined medium-resolution climate data with high-resolution topographic data to capture spatial and temporal details. The downscaled climate data were then used to simulate the impacts of climate change on hydrology and water quality in a small basin. The results demonstrated the effectiveness of the downscaling method for spatially differentiated simulations.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.

Summary: This study investigated the distribution and transformation of dissolved organic nitrogen (DON) in riverbed sediments impacted by effluent discharge. The authors found that the spectral characteristics of dissolved organic matter (DOM) in surface water and sediment porewater could be used to predict DON variations in riverbed sediments. Random forest and extreme gradient boosting machine learning methods were employed to provide accurate predictions of DON content and properties at different depths. These findings have important implications for wastewater discharge management and river health.
