Summary: This study investigates the contribution of functioning playas to aquifer recharge in the Central High Plains region using physical and geochemical evidence. The results indicate higher recharge rates beneath the playa compared to the interplaya, similar to findings in the Southern High Plains region.

Summary: Population growth and climate variability have increased the need to enhance freshwater security and diversify water supplies, leading to the global use of managed aquifer recharge (MAR). However, the introduction of recharge water may alter geochemical and hydrological conditions in receiving aquifers, potentially mobilizing toxic naturally occurring contaminants and threatening human and ecosystem health.

Summary: Bank filtration has been proven effective in removing diclofenac through various biogeochemical processes. The ideal conditions for diclofenac removal include aerobic conditions, higher temperatures, neutral pH, and sediments with heterogeneous fractions. However, there is still debate on which factor contributes the most to the attenuation mechanism. Further research is necessary to better understand the degradation and mobility of diclofenac for improved removal efficiency.

Summary: The late Miocene Ogallala Formation constitutes a significant portion of the High Plains aquifer in North America, mainly located in the central High Plains region. However, there is limited research on this formation in this particular area. In western Kansas, the Ogallala Formation is well-exposed along the bluffs of Ladder Creek Canyon, with a thickness of up to 40 meters. It consists of stacked and laterally extensive sandy channel bodies, indicating the presence of braided river systems.

Summary: Aquifer recharge is crucial for understanding groundwater volumes and sustainable use of natural water resources. This study evaluated various methods to determine recharge in a flood basalt terrain, revealing the influence of snowmelt on recharge. By combining groundwater modeling and hydrologic tracers, the appropriate recharge values were determined for different terrains.

Summary: This study investigates the stream-aquifer interactions in the Lower Flint River Basin in Georgia, USA. The results show the effects of local water use on streamflow and provide new insights into hydraulic processes in karst systems. It also estimates hydraulic parameters for future modeling efforts.

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: 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: The acequias de careo are ancient water channels excavated during the early Al-Andalus period in Southeastern Spain, which collect snowmelt and runoff to recharge aquifers in the Sierra Nevada mountain range. This system not only extends water availability in the lowlands during dry seasons, but also increases total aquifer recharge by 92%.

Summary: The study used a reactive transport model to analyze the impact of Agricultural Managed Aquifer Recharge (AgMAR) on nitrate (NO3-) leaching to groundwater under different management strategies. Simulation results indicated that finer textured sediments are crucial for providing conditions needed for denitrification, while applying water all-at-once may exacerbate groundwater quality issues but also increase denitrification within the vadose zone. The research concludes that AgMAR can be designed to enhance denitrification in the subsurface and reduce NO3- leaching to groundwater.

Summary: Over the past three decades, the average farm size in the United States has more than doubled, impacting the agricultural industry and rural communities. Research shows that increasing farm size can decrease groundwater extraction, but larger farms using different irrigation technologies offset this reduction, leading to a slight increase in overall groundwater use. Groundwater depletion also increases the likelihood of farmland being sold to larger farms, exacerbating the cycle of groundwater depletion and farmland consolidation.

Summary: This study examines the potential benefits of adding an artificial recharge facility in California to offset groundwater overdraft and prepare for drought. The results show that this facility can increase groundwater storage, reduce overdraft, and increase hydropower without significantly impacting environmental flows. Additionally, artificial recharge has economic benefits by reducing water shortage and surface water storage costs, and increasing hydropower revenue.

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: 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.
