Summary: This study investigated the interaction between saline water, natural fresh groundwater, and freshwater injected in managed aquifer recharge (MAR) through sand tank experiments. The research found that injecting water near the saltwater-freshwater interface was more effective in reducing seawater intrusion, and the created freshwater bubble could act as a barrier against intrusion. Optimization of MAR is crucial in combating seawater intrusion effectively.

Summary: We conducted experimental tests on salt samples from different geographic origins including strain-controlled tests, constant mean stress tests, and long creep tests. The analysis of the experimental results considering heterogeneity is essential for reliable rock characterization and constitutive modeling, especially in relation to volumetric strains and dilatancy onset in salt formations. Material heterogeneity caused by impurities can explain the differences observed between local and global measurements. It is also important to consider the proportion of volumetric strains compared to deviatoric strains and the preconditioning process for accurate analysis.

Summary: This study aims to develop a predictive model for nitrate removal during infiltration in managed aquifer recharge (MAR) by synthesizing observations from laboratory tests, field experiments, and operational facilities. The study finds that urban areas have the highest potential for load reduction, even under relatively dry conditions.

Summary: This study discusses the possibility of backflushing a Vadose zone well (VZW). By isolating the clogged lower section of the well and saturating its surrounding with water through the unclogged upper screen, the water is sucked from the surrounding soil into the isolated section under negative pressure. The experiment shows successful reversal of flow direction in both cases with and without a gravel pack. The degree of redevelopment was measured by the drainage time of the well.

Summary: This study systematically tested the influence of salt basin geometry on salt tectonics through analogue experiments, showing that the initial salt depocenter location and mean salt thickness are dominant factors controlling deformation. The experiments were qualitatively analyzed using top view photography, and quantitatively through Particle Image Velocimetry (PIV) and 3D photogrammetry (Structure-from-Motion, SfM) to obtain surface displacement and topographic evolution.

Summary: Groundwater in shallow aquifers used for community water supply in cold climates is vulnerable to contamination from land-use and surface water intrusion. This study used stable water isotopes data, precipitation data, Geographic Information System analysis, and multivariate statistics to assess surface water intrusion risks and recharge conditions in Northern Finland. The results showed that warm season precipitation contributes to about 60% of the annual precipitation, and the aquifers have a mixture of warm and cold season precipitation. The use of stable water isotopes with lc-excess is a useful approach for assessing recharge and contamination risks in water management.

Summary: Mountain block recharge is an important component of the water budget for alluvial aquifers, but understanding and quantifying its dynamics is challenging. This study investigates two alluvial aquifers in Haiti and finds that river infiltration from the mountain block is a major source of recharge. The study also highlights the significance of the Massif de la Selle carbonate aquifer system, which has a much larger recharge than the alluvial aquifers and supplies a significant portion of the water to the metropolitan area of Port-au-Prince.

Summary: Pumping distress refers to the phenomenon of dynamic water entering a pavement and being pumped out of the pavement void under traffic loading. This study conducted a quantitative analysis through field investigations and laboratory experiments to understand the factors contributing to pumping distress on bridge decks. The results revealed that the formation reason, deterioration rate, and damage degree of pumping distress were different between the truck and emergency lanes, and were related to uneven construction, compaction segregation, and poor drainage.

Summary: Most river deltas are densely populated areas with intensive agriculture. The increased shortage of fresh surface water leads to increased groundwater pumping, resulting in sea water intrusion. Understanding the current distribution of fresh-salt groundwater is crucial for predicting the future of fresh groundwater resources in deltas, but uncertainties about these distributions and their drivers are significant.

Summary: This study examines the water scarcity issue in southwestern Bangladesh and the potential of Managed Aquifer Recharge (MAR) technology in providing safe drinking water. There is a mismatch between social necessity and technical suitability, leading to different solutions in different regions. The approach developed may serve as a useful guide for evaluating MAR potential in other saline deltas worldwide.

Summary: Research suggests that there is significant potential to build coproduction plants for seawater desalination in the United States, which could compete financially with existing desalination facilities and reduce carbon emissions. Selective salt recovery can help alleviate the issue of residual concentrate disposal, while also generating additional revenue.

Summary: The study assesses the potential impact of drought on arsenic exposure from private domestic wells in the conterminous United States. Results show that drought conditions increase the probability of elevated arsenic concentrations in domestic wells, indicating adverse effects on public health.

Summary: Research conducted in an experimental catchment in South Australia revealed a paradox in groundwater flow dynamics due to differing groundwater types and recharge rates. During droughts and dry years, high-salinity groundwater contributed a larger proportion of stream flow compared to low-salinity groundwater. This paradox can be explained by the differing drainage rates of the geological formations, leading to varying contributions to stream flow during different hydrological conditions.
