Summary: This study focuses on changes in groundwater storage and their relationship with groundwater-level changes in the groundwater basin underlying the City of Albuquerque. Repeat micro-gravity measurements were used to measure groundwater storage change from 2016 to 2021. The study produced a map of specific yield based on gravity-derived storage change and groundwater-level change, allowing inference of this property over a wide region.

Summary: Groundwater lens is crucial for providing freshwater supply for inhabitants of small islands, and its profile and volume are sensitive to factors such as topography, soil type, and human activities. Spatial recharge patterns have a significant impact on the lens volume, with smaller recharge areas or a more concentrated recharge rate resulting in a larger lens volume for a given constant total recharge.

Summary: The depletion of surface water due to climate change increases the global water demand, making groundwater resources the primary source of freshwater supply. However, overexploitation and inadequate management can lead to irreversible contamination. This study evaluates the use of geophysical methods to estimate hydrogeological parameters and assesses marine intrusion in a coastal aquifer in Algeria. The results provide valuable information for groundwater resource management and effective delineation of the seawater/freshwater interface.

Summary: Modeling groundwater is an important aspect in hydrology, providing support for human life and agricultural land. Artificial recharge, a crucial part of groundwater modeling, helps estimate groundwater levels and varies based on ground conditions. Spatial representations are used to estimate groundwater mapping. The MODFLOW model is commonly used for designing the graphical structure. This review collects ground-level data from various regions and discusses existing works, providing support for researchers in overcoming past difficulties and finding better solutions for the future.

Summary: This paper presents a novel analytical approach to estimate groundwater travel time distribution in urban areas, considering the impervious urban structure and modified aquifer hydraulic properties. The proposed analytical model is verified through comparison with numerical results and sensitivity analysis. The results show that urban groundwater travel time distribution is strongly dependent on construction-related parameters and aquifer compressibility, suggesting the need for adaptive groundwater management strategies for different aquifer types. The proposed model has important implications for water resources management, urban groundwater utilization, and aquifer quality in urban areas.

Summary: This study analyzes surface deformation in California's San Joaquin Valley using radar and positioning data, showing that subsidence rates were twice as high in 2016 compared to 2017, possibly due to increased groundwater pumping. In the wetter 2017 water year, the locations of greatest subsidence migrated outward, possibly reflecting a surplus of water supply in low-lying areas. Patterns in seasonal deformation reveal entry points and potential pathways for groundwater recharge.

Summary: This study investigates the effect of oceanic tides on the control of seawater intrusion through artificial freshwater injection. The results show that the effectiveness of artificial freshwater injection is significantly reduced under tidal conditions, with higher salinity concentrations experiencing faster movement and seaward displacement. The study also finds an overshoot phenomenon that further decreases the effectiveness of freshwater injection, especially with increased injection rates and tidal amplitudes.

Summary: The majority of freshwater in the aquifers of the Ningbo Basin has been replaced or mixed with seawater due to tectonic activity. Only one freshwater lens remains in the central area of the basin. Research on the deep confined freshwater lens in the basin is lacking and evidence is insufficient. Data from monitoring wells indicate ongoing groundwater exploitation. Tectonic stress field evolution and fault analysis suggest that concealed faults likely act as conduits for water. Tests and analyses of hydrochemical ions and isotopes confirm the hypothesis that the deep confined aquifers are recharged with modern water from the bottom through concealed faults.

Summary: Given the decline in groundwater levels in California's Central Valley, it is important to implement managed aquifer recharge to supplement groundwater systems. This study assessed the use of airborne electromagnetic (AEM) data to locate incised valley fill (IVF) deposits, which can serve as optimal sites for recharge. The AEM data successfully identified IVF deposits in the Kings River alluvial fan, demonstrating the potential for this method to rapidly locate and utilize these valuable natural infrastructures for groundwater recharge.

Summary: This study developed a steady-state analytical solution using the single potential approach to quantify the maximum safe pumping rate in sloping unconfined coastal aquifers. It found that coastal aquifers with a higher aquifer bed towards inland yield a higher maximum safe pumping rate compared to those with a horizontal aquifer base. Neglecting the aquifer base slope can lead to significant errors in estimating the maximum safe pumping rate. The results provide valuable insights into the effect of the aquifer base slope on pumping-induced seawater intrusion in coastal aquifers and offer a useful tool for quick assessment.

Summary: The study analyzed the temporal and spatial variations of groundwater in the Quaternary aquifer in UAE, revealing a significant decrease in freshwater resources and increase in brackish water. Continuing the current groundwater exploitation could deplete freshwater resources in agricultural areas, necessitating more focus on the management of brackish water resources.

Summary: Studies have shown that applying mathematical integration to line-sink solutions, like the one developed by Hantush in the 1960s, can be directly used to derive analytical solutions for a variety of hydrogeological settings. This approach allows for the consideration of different factors such as the presence of pumping wells, aquifer boundaries, and recharge areas, providing a unique solution that can be applied to managed aquifer recharge designs.

Summary: The study assessed the use of electrical resistivity tomography (ERT) combined with borehole data to analyze the spatial variability of groundwater storage in weathered/fractured basement rock aquifers. Results showed the importance of hydrogeological conceptual constraints provided by ERT and the influence of clay minerals on resistivity data in accurately predicting groundwater storage properties. The study demonstrated the potential of resistivity tomography for quantifying groundwater storage heterogeneity in such aquifers with reasonable uncertainty.

Summary: The livelihoods of the rural population in the Cambodian Mekong delta are influenced by annual floods, but the dynamics of floodplains are changing due to climate change and hydropower development. While previous studies have assessed the changes in river discharge and flood extent on a larger scale, this study focuses on the local and specific scales, using a methodology to track the evolution of hydrological regimes and inundations. The results show changes in the incidence, duration, and spatial distribution of floods, with a decrease in inundation duration and frequency during the traditional flood season.

Summary: This brief provides the necessary data for calculating and assessing the robustness of a water level-flood link (WAFL) in the Cambodian Mekong Delta. The data includes raster files for two zones in the delta, as well as in-situ water level data, vegetation extents, and raster files representing the incidence and duration of inundations. These data are important for analyzing long-term changes in Monsoon inundations in the region.
