Summary: The study investigated the impact of the South-to-North water diversion Middle Route Project (MRP) on groundwater storage in North China Plain (NCP) by comparing changes before and after MRP operation. It found a significant recovery trend in groundwater storage after the operation of MRP, particularly in regions where groundwater over-utilization had occurred.

Summary: This paper investigates the spatiotemporal characteristics of groundwater storage changes in the North China Plain during 2003-2020. The study reveals that groundwater storage has continued to decrease after the implementation of the South-to-North Water Diversion Middle Route Project. However, the recovery of groundwater storage in Beijing is faster compared to the plain areas of Hebei and Tianjin. Precipitation is identified as the main driving factor of groundwater storage changes.

Summary: Based on 556 well monitoring observations over a period of 13 years, the sustainability of shallow groundwater in the North China Plain was evaluated quantitatively using various indices. The main conclusions are that there is a serious long-term deficit of shallow groundwater in the Piedmont Plain, while the reliability and resilience of shallow aquifers are below medium level in most areas. Non-climatic factors are found to be the dominant driver of shallow groundwater depletion in the region.

Summary: The South-to-North Water Diversion Project Central Route is the largest water control project ever built, aimed at reallocating water resources from South China to North China. Since its operation in 2014, it has significantly changed the water supply pattern in Beijing and reduced groundwater extraction and land subsidence.

Summary: In this study, the spatiotemporal evolution of groundwater storage (GWS) in a confined aquifer system in Hengshui, North China Plain was analyzed. The results show a significant decrease in GWS during the study period, primarily driven by climate variability and anthropogenic activities. The integration of different data sources allows for the separation of these two influences. Additionally, traditional well observations alone are insufficient to capture the spatiotemporal evolution of GWS due to their limited spatial density.

Summary: The South-to-North Water Diversion Project (SNWDP) has improved water shortage but its impact on groundwater chemistry, particularly fluoride and salinity, is still unclear. Research conducted in Cangzhou, a recipient city of the SNWDP, found that fluoride concentration decreased after the project, especially in areas with land subsidence. However, groundwater salinity increased after the SNWDP, leading to a rise in fluoride concentration. The findings provide valuable insights for groundwater resource management.

Summary: In this study, the changes in water storage in the water-receiving area of the South-to-North Water Diversion Eastern Route Project (SNWDP-ER) were analyzed using the latest Gravity Recovery and Climate Experiment (GRACE) technology. The study found that the implementation of SNWDP-ER aided the recovery of surface water but had little effect on groundwater and terrestrial water storage. Human activity and climate change have accelerated the decline of groundwater, leading to a decrease in terrestrial water storage.

Summary: The South-to-North Water Diversion (SNWD) is an infrastructure project in China that aims to alleviate water shortages in north China. It has had significant social, economic, environmental, and ecological impacts, particularly in the Beijing-Tianjin metropolitan area, since 2015. This study used various data sources to assess the impacts of SNWD on land subsidence in Tianjin and revealed that reduced groundwater pumping due to SNWD has slowed down the overall subsidence. The findings also highlight the importance of coordinating groundwater and surface water uses for land subsidence mitigation.

Summary: Following the operation of the middle route of the South-to-North Water Diversion Project, the total water transfer to Beijing has exceeded 5.0 km(3), leading to significant changes in Beijing's water use structure. While the SNWDP has helped alleviate land subsidence issues in Beijing, the main pressure on Beijing's water supply still comes from improved living standards, the popularization of water-using appliances, and rapid development in the accommodation and catering industries. With an expected increase in precipitation in the Beijing region over the next decade, there is a greater likelihood of rapid groundwater recovery, but climate extremes could potentially challenge the success of the SNWDP during certain dry periods.

Summary: Water resources management in Africa is critical. This study assesses the spatiotemporal variability in water storage and its controls in major African aquifers. The results show declining trends in water storage in northern Africa due to irrigation water use, while rising trends are found in western Africa due to land use change and increased recharge. Climate extremes strongly control water storage in eastern and southern Africa.

Summary: Nuclear magnetic resonance (NMR) logging is a promising method for estimating hydraulic conductivity (K). In this study, five models were used to derive estimates of K in glacial aquifers based on NMR logging data acquired in central Wisconsin. The sum-of-echoes (SOE) model showed the best agreement with direct push permeameter (DPP) measurements. The Timur-Coates model provided significantly different estimates of K compared to DPP measurements.

Summary: Glaciers in High Mountain Asia (HMA) have been retreating due to global warming, leading to water scarcity for humans and ecosystems. This study developed a hybrid modeling approach to project glacier change and found that maritime glaciers have higher melting rates and negative net balances compared to continental glaciers. By the year 2100, both glaciers are projected to almost completely melt under the highest emission scenario. The projected year for the continental glacier to halve in volume (area) is about 5-11 (14) years later than that of the maritime glacier.

Summary: This study introduces a new method that combines geodetic and in situ groundwater data to estimate groundwater storage change in the Parowan Valley. The results show that both fine- and coarse-grained layers contribute equally to the total groundwater storage loss, but fine-grained layers dominate in confined aquifers. These findings have important implications for understanding the source of groundwater in depleting aquifer systems.

Summary: This study found non-monotonic changes in river flows for seven major rivers originating from the Tibetan Plateau at warming levels of 1.5 degrees C, 2.0 degrees C, and 3.0 degrees C. River flows decreased by 0.1-3.2% at 1.5 degrees C warming level and increased by 1.5-12% at 3.0 degrees C warming level. The variations in river flows were influenced by rainfall, snowmelt, and glacier melt. Reduced river flows threaten water security in riparian countries, while elevated flood risks are expected with further temperature increases over the Tibetan Plateau.

Summary: The Lancang-Mekong River is an important transboundary river in Southeast Asia. Monitoring changes in reservoir water storage and quantifying the impact of reservoir operation is crucial. This study used multisource remote sensing to generate weekly water levels and water storages of nine largest reservoirs on the main stem of the river. The results demonstrate the great potential of multisource remote sensing for high-temporal-resolution monitoring of reservoir water levels and water storage.

Summary: Lake ice is an important factor in regulating regional hydroclimate and lake ecosystems. Traditional methods of estimating water levels in ice-covered lakes using satellite altimetry are often affected by winter anomalies related to the thickening of lake ice. This study presents a novel method that combines altimetric waveforms and backscattering coefficients to estimate lake ice thickness without relying on in situ data. The method shows high accuracy and is effective at detecting thin ice that cannot be retrieved by altimetric waveforms. The study also improves the estimation of water levels for ice-covered lakes through the merging of lake water levels derived from different threshold methods.
