Summary: The Mexico City Metropolitan Area, as the most important economic center in Mexico, has been facing challenges due to overexploitation of groundwater and the resulting impacts on hydrological conditions and infrastructure. This article presents a new integrated conceptual model of the Mexico Basin Aquifer, which improves the understanding of aquifer characteristics and current groundwater dynamics. The model can serve as a basis for building a numerical model and testing different management scenarios for decision-making.

Summary: Land subsidence is the gradual or sudden dropping of the ground surface developed by increasing the total stress. This study evaluates the hydrogeological and water chemistry characteristics of construction sites with land subsidence. The findings show that groundwater levels gradually increased after land subsidence, while groundwater quality continued to be affected by saltwater.

Summary: The study reveals the hydrogeological framework and urbanization impact on the groundwater resources in the Quaternary aquifer of south Bengal Basin, India. It shows that long-term groundwater overdraft has led to land subsidence and deterioration of groundwater quality, with the area of groundwater trough expanding significantly due to rapid urbanization between 1985 and 2016.

Summary: In developing countries like Honduras, sustainable groundwater management is hindered due to nonexistent or outdated hydrogeological information. This study focuses on the Siguatepeque aquifer and highlights the lack of adequate management strategies, which jeopardizes the sustainability of the aquifer as the main water supply source. The study establishes the hydrogeological units and water balances of the aquifer, providing essential information for groundwater management. The analysis of historical data reveals a continuous decline in groundwater levels, particularly in urban areas, indicating potential overexploitation of the aquifer.

Summary: This study used an integrated methodology to assess the causes of waterlogging and its impact on groundwater quality in the desert fringes of the Nile Valley in Egypt. Findings suggest that flood irrigation, non-planned cultivation, and wrong management decisions significantly contributed to the development of waterlogging in the area.

Summary: This study aims to develop an efficient and cost-effective method to extract and evaluate microplastics in a sedimentary aquifer based on the hydrogeological characteristics of the area. The findings show that microplastics in groundwater have higher circularity and Feret diameter compared to those in surface waters, indicating that their shape plays a more significant role in transport in porous aquifers. Additionally, aquifer recharge does not alter the characteristics of microplastics in groundwater.

Summary: In response to the increasing water demands in expanding cities, many aquifers in Mexico, particularly in the Aguascalientes Valley, are being overexploited and deplete, resulting in land subsidence, ground faulting, and damage to infrastructure. This study, utilizing the longest SAR survey conducted in the Aguascalientes Valley, analyzed the structurally-controlled subsidence process and associated risks. The research revealed a pattern of subsidence linked to alluvial/fluvial deposits, with maximum settlement rates increasing over time. The study also identified previously unknown deformation patterns and zones of strain, providing valuable insights for subsidence risk assessment and urban planning in the region.

Summary: The groundwater exploitation in Dezhou has led to accelerated land subsidence. The main contributors are AgII and AgIII, accounting for 74% of the total subsidence. Understanding the deformation mechanism of AgII is crucial for subsidence control.

Summary: This study provides a comprehensive review of global land subsidence (LS) cases, revealing that LS predominantly occurs in large metropolitan cities and coastal plain and river delta regions. Human-induced factors, particularly groundwater extraction, play a significant role in LS occurrences, showing strong correlations with groundwater withdrawal and groundwater level decline.

Summary: This study focuses on the confined aquifer system in the Calama basin of northern Chile, using a combination of hydrodynamic, hydrogeochemical, and isotopic methods to evaluate groundwater residence time, recharge sources, and isotopic fractionation. The research provides insights into the interaction between groundwater and surface water in hyper-arid areas and the potential applications in managing scarce groundwater resources.

Summary: Land subsidence in the Nile Delta is caused by excessive pumping from the aquifer, which can lead to damage to infrastructure and agricultural resources. Reducing aquifer recharge and increasing abstraction both contribute to land subsidence, and their combination intensifies the subsidence.

Summary: Tracking the inelastic deformation of an aquifer is crucial for understanding the stress it experiences and evaluating the impact of extraction practices in a region's hydrogeological setting. However, monitoring the transition from elastic to inelastic deformation is challenging, especially in a dry climate like the Abarkuh Plain (AP). In this study, we used multi-sensor Interferometric Synthetic Aperture Radar data from 2003 to 2020 to define the confined extent of the aquifer system and track the spatial evolution of inelastic deformation in central Iran. Our findings indicate that previously unaffected areas are now experiencing inelastic deformation, resulting in irreversible subsidence and aquifer storage loss. The thickness of compacted clay units and declining water heads within the confined extents of the aquifer system play significant roles in controlling and driving long-term compaction.

Summary: Geological deformations like anticlines play a significant role in aquifer system functioning. A multidisciplinary approach is proposed to characterize and quantify the impact of these features. Research in southwestern France has led to a better understanding of the complex architecture of aquifers and their interconnections with confining units.

Summary: Unsustainable groundwater extraction can result in various negative impacts including aquifer compaction, damages to infrastructure, changes in water accumulation, and reduced water storage capacity. This study focuses on the heavily exploited aquifers in the New South Wales Riverina region of Australia and uses satellite radar imagery to detect ground deformation caused by groundwater extraction. Four areas with potential for groundwater-induced deformations are identified, and the study provides valuable information for water managers to mitigate the risks associated with groundwater-related ground deformation.

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: A hydro-mechanical model is established to investigate the monopile-seabed interaction in cross-anisotropic sandy seabed under wave loadings, considering the nonlinear behaviors of slip and separation between monopile and soil. The results show that increasing seabed anisotropy leads to a decrease in vertical coefficient of permeability, an increase in vertical elastic modulus and shear modulus, and a decrease in Poisson's ratio. These effects have implications on excess pore water pressure, momentary liquefaction, lateral displacement, bending moment, and wave-induced settlement of monopiles.
