Summary: Managed Aquifer Recharge (MAR) and Surface Water Recharge (MSWR) are effective strategies for climate change adaptation and have potential for thermal energy exploitation. However, adaptable implementation strategies of MAR and MSWR with concomitant exploitation of thermal energy potential have yet to be developed. This study presents strategies for the exploitation of hydrologic and energetic potentials of MAR and MSWR, taking into account hydrogeological conditions, legal aspects, and climate scenarios.

Summary: Managed aquifer recharge is a human intervention to supplement groundwater aquifers and mitigate climate uncertainty's impact on irrigated agriculture. It has the potential to increase groundwater levels and be subject to second-best arrangements among water users. However, the quantity recharged is sensitive to climate conditions and hydrological properties.

Summary: Research on the influence of climate change on groundwater recharge reveals that there is significant uncertainty in the models used, with most studies only considering inter-model uncertainty and not fully addressing intra-model uncertainty or emission scenario uncertainty. Overall, a decline in groundwater recharge can be expected in most regions, though the extent of the decline varies based on emission scenarios and seasons.

Summary: This paper proposes methods to quantify the sensitivity of groundwater level and recharge to temporal climate variability across Australia. It found that the sensitivity of head and recharge to precipitation change is nationally correlated, suggesting large-scale effects. These findings provide valuable insights for sustainable groundwater management.

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 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: Researchers in India conducted a pilot-scale hydrogeochemical study in the Ramganga sub basin, using a modified version of managed aquifer recharge (MAR) to effectively utilize floodwaters for groundwater recharge and quality improvement. The project successfully demonstrated the benefits of the modified MAR approach in enhancing aquifer recharge and improving water quality.

Summary: This research aims to evaluate the influence of groundwater table inclination, topography, and other local characteristics on Managed Aquifer Recharge (MAR) efficiency from the perspective of Groundwater-Dependent Ecosystem (GDE) restoration. The results suggest that initial hydraulic head difference, model length, and hydraulic conductivity are critical parameters affecting water level increase at the discharge area. The study provides insights into MAR efficiency and contributes to optimizing MAR systems.

Summary: Groundwater extraction exceeds renewability in most MENA countries, limiting freshwater resources for food production. Future climate predictions indicate increased rainfall, leading to more floods and flash floods in the region. Demand management and MAR technology are necessary to overcome groundwater depletion and climate change impacts, improving groundwater quality and reducing stress on resources.

Summary: Warming temperatures increase crop evapotranspiration demand, leading to increased irrigation and exacerbating water scarcity. Previous research on climate change impacts has relied on irrigation water requirement models, but these models have uncertainty and do not consider irrigators' risk-averse behavior. Using well-level data from the High Plains Aquifer in Kansas, we develop regression models to estimate how changes in vapor pressure deficit and precipitation affect groundwater withdrawals for corn, soybeans, and wheat. Increases in withdrawals are expected for all three crops, with the largest increase for soybeans. Accounting for CO2 improvements, total withdrawals are projected to increase by 5.9% (7.6%) by mid-century under RCP 4.5 (8.5). This increase in withdrawals is expected to accelerate aquifer water level decline, making it important to consider when projecting future aquifer conditions.

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: The Piper diagram is commonly used in groundwater hydrochemical studies, but faces limitations in representing large datasets. To address this issue, the D-Piper diagram displays spatial point density instead of individual points, improving visualization and interpretation as data points increase. Furthermore, various representation methods help users uncover hidden hydrochemical structures accurately.

Summary: This study conducted a 21-year research on eight ponds in Donana National Park in southern Spain, and found that local factors have a significant impact on the flooded area and water level of the ponds. The study shows that, in addition to a decrease in precipitation, ponds in areas closer to pumping facilities and at higher altitudes are more vulnerable to degradation.

Summary: Thermal recycling is a major cause of efficiency loss in groundwater heat pump systems and understanding its effects on system performance is crucial for system design. This study addresses the nonlinearity of the thermal recycling problem using distributed numerical models of groundwater flow and heat transport combined with thermodynamic models of geothermal heat pumps. Simulation results show that thermal interference between production and injection is unavoidable and can lead to the inoperability of the heat pump in certain scenarios. Thermal recycling is also found to increase operation costs and have an environmental impact. The findings of this study improve our understanding of thermal recycling as a complex and transient process that results in efficiency loss in groundwater heat pump systems.
