Summary: Many places, especially in dry areas with hot climates, are facing the problem of water scarcity, particularly in the summer. Some companies have developed solutions to mitigate water evaporation by covering the water with floating balls or using floating solar panels, which not only reduce evaporation but also provide an additional power source for hydropower plants.

Summary: Operating rules play a crucial role in enhancing water utilization in reservoirs. Previous studies focused on minimizing the shortage index, but neglected the economic objectives. This study formulates a function to minimize economic loss for better supply-demand relationship. The results show that the derived function outperforms traditional rules and depicts a non-linear supply-demand relationship.

Summary: The study demonstrates a new method of fabricating Ta3N5 photoanodes using evaporated TaF5 as the source of tantalum. The as-synthesized Ta3N5 layers were uniformly deposited on different large-area substrates with columnar crystals, functioning as efficient active photoanodes for PEC water splitting. This approach could lead to high-quality Ta-based photoanodes over large areas, using insights gained from the precursor TaF5 for nitrides.

Summary: Water shortage is a serious issue in the North China Plain (NCP), a densely populated and urbanized region that is known for agriculture. A study on the changes in surface water body area (SWA) in the NCP from 1987 to 2020 revealed a significant expansion, mainly driven by the construction of reservoirs/lakes and aquaculture development. This expansion has led to increased water evaporation, exacerbating the water shortage in the region. Climate change is predicted to further increase water evaporation, posing more challenges to regional water resources.

Summary: Agricultural reservoirs in arid regions increase water stresses and threaten the sustainability of water resources. Limited research on their effects hampers a comprehensive assessment of sustainable water use. This study uses stable isotopes to evaluate the impact of agricultural reservoirs on hydrology, showing that they alter local hydrologic patterns, increasing evaporation and enriching the water near the reservoir. The cumulative effect of multiple reservoirs profoundly alters hydrologic processes, leading to evaporation-led water loss in inland river basins.

Summary: This study provides direct measurements of evaporation from Standley Lake, revealing its seasonal patterns and the factors influencing it. Summer evaporation is mainly driven by diurnal variations in wind speed and the vapor pressure gradient, while fall and winter are influenced by negative sensible heat transfer. Overall, evaporation plays a significant role in the energy balance of Standley Lake.

Summary: Evaporative losses from small seasonal water reservoirs in semiarid regions can be significantly reduced with self-assembling floating covers, with summer evaporation suppression ranging between 65% and 80%. The study also found that replacing black disks with water-filled black polyethylene balls improved suppression efficiency. Additionally, despite differences in energy partitioning, evaporation rates from white and black covers were relatively similar.

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: 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.
