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 combines geochemical tracers and geophysical methods to assess anthropogenic aquifer recharge (AAR) processes in a small floodplain in the Mornag plain, NE of Tunisia. The results confirm the connection between streams and aquifers, and detect the AAR from saline effluent in the downstream area. Isotopic tracers and electrical resistivity tomography are effective tools in investigating recharge processes and the role of the Wadi. The evaluation of groundwater suitability for irrigation shows that except for the water from the hill dam and upstream groundwater, the remaining zones are not suitable. The findings emphasize the water sustainability threat in the region and advise decision-makers to control Wadi runoff and protect it from pollution sources.

Summary: The increase in extreme precipitation events due to climate change and urban development has led to a need for new stormwater management facilities. The Canary Islands have developed a unique facility called a dry gallery, which utilizes water mines for the management of stormwater. However, the lack of scientific knowledge about these facilities has hindered their proper design and management. This study provides the first simulation of the infiltration process and wetting front propagation from dry galleries, offering recommendations for their installation and sizing. The results show that the infiltration process is highly transient and neglecting unsaturated conditions or geological configuration could lead to a significant underestimation of sizing.

Summary: Growing demands on water supply have led to overexploitation of aquifers, resulting in a decline in groundwater quality. Managed aquifer recharge (MAR) has been proposed as a solution, but its effectiveness on improving regional groundwater quality caused by non-point sources is uncertain. This study used geostatistical and numerical models to investigate the impacts of different MAR strategies on groundwater quality, and found that strategic, high-intensity recharge operations in geologically favorable subregions can significantly improve groundwater quality in terms of salinity. However, it would take decades to alleviate groundwater quality concerns in the studied region.

Summary: The Zagreb aquifer is a crucial water supply source for the capital of Croatia. However, in the past 50 years, the groundwater levels have significantly decreased, particularly at the Mala Mlaka water-supply site, affecting normal functioning. Managed aquifer recharge methods are proposed to address this issue and ensure continuous water supply.

Summary: This study examines well clogging in an aquifer storage transfer and recovery (ASTR) system used for securing freshwater supply for a flower bulb farm. The system faced clogging issues due to the composition of the collected tile drainage water (TDW) exceeding clogging mitigation guidelines. Substituting sand filtration with disc filters led to insufficient treatment and rapid clogging of injection wells. Physical clogging by particles was identified as the main cause, and measures such as periodical backflushing and regulating maximum turbidity protected ASTR operation but reduced injected TDW volume.

Summary: Assessing the morphodynamic groundwater reserves is crucial for sustainable water resource management. A study proposes an information-based model to evaluate natural groundwater reserves in a part of the Ganga basin in Northern India, where there is spatial variability in natural groundwater reserves. The study utilizes marginal information of rainfall data and transinformation between rainfall and monthly depth to groundwater level measurements to estimate recharge rates and annual rainfall input to groundwater reserves, providing guidance for sustainable groundwater resource management in the morphodynamic system of the Ganga river basin.

Summary: Through laboratory experiments and numerical simulations, it was found that cold freshwater recharge performs better in mitigating seawater intrusion compared to hot water, which induces a marked overshoot of salinity distribution.

Summary: Groundwater in Iraq is considered an alternative source of water for areas far from surface water. A study simulated the effect of artificial recharge on groundwater quantity using a modeling system, showing that injecting treated water can raise water levels and potentially create new agricultural areas.

Summary: This study investigates the combined effects of density and dual-domain properties on aquifer storage and recovery (ASR). The results show that the interactions between density effect and dual-domain mass transfer can lead to complex controlling patterns and influence the recovery efficiency and mixing processes during ASR.

Summary: This research focuses on the importance of the vadose zone in artificial recharge and the impacts of infiltration basin features and vadose zone factors on water distribution. The experimental results showed that different formation characteristics have varying effects on evaporation, and there are consistent or different variation trends between infiltration and recharge.
