Summary: This study conducted laboratory experiments on sandy columns and found that hydrological and biogeochemical controls play essential roles in regulating nitrogen dynamics during different stages of wetting-drying cycles in intermittent managed aquifer recharge (MAR) systems. Intermittent MAR functioned as a nitrogen sink while providing a carbon source for nitrogen transformations, but it occasionally became a source of nitrogen under intense flushes of preferential flow. A saturated zone mediated nitrogen dynamics by creating oxygen-limited conditions for denitrification and buffering the effects of preferential flow.

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: The mobility of molybdenum in groundwater systems has been studied using a comprehensive hydrochemical dataset collected during a multi-cycle aquifer storage and recovery test. It was found that the initial mobilization of molybdenum occurs through a series of reactions, involving pyrite oxidation, dolomite dissolution, and the release of molybdenum bound to soluble sulfurized organic matter. Once released, molybdenum mobility is primarily controlled by pH-dependent surface complexation reactions and the capture by iron sulfides.

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: Managed aquifer recharge (MAR) techniques are needed to address water scarcity challenges caused by climate change and excessive groundwater usage. One major technical issue with MAR systems is physical clogging, which reduces the infiltration capacity of the recharge site over time. This study aims to identify key factors contributing to clogging in the field and develop a model for reproducibility at other sites. The research is conducted in Suvereto, Italy, and includes analysis of spatial factors and erosion processes. The model is validated through field measurements and offers advantages over existing clogging models in terms of transferability to other MAR sites.

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: This study focuses on the unsustainably high levels of groundwater use in Dak Lak province, Vietnam. It explores the potential of managed aquifer recharge (MAR) to boost groundwater storage and presents findings from five farm-scale pilots. The study highlights the contrasting performance of the pilots and the influence of factors such as water quality and farmer attitudes. These insights can be valuable for regions with high groundwater dependence but limited experience in MAR.

Summary: Managed Aquifer Recharge (MAR) is the intentional recharge of water to aquifers for subsequent recovery or environmental benefit. MAR can increase water security in drought more economically than new dams, augment existing dams with higher efficiency storage, augment groundwater desalination schemes, and facilitate conjunctive use of surface and groundwater resources. Australia currently has 10 operational MAR schemes to increase agricultural activity, providing a total capacity of around 70 x 10(6) m(3)/year.

Summary: Overpumping and overexploitation of groundwater pose major threats to aquifer systems in arid and semi-arid regions. Managed aquifer recharge (MAR) is suggested as a sustainable and effective method to mitigate these negative impacts. Optimizing artificial recharge involves selecting suitable MAR sites based on surface and subsurface characteristics.

Summary: This study developed a flow and multi-component reactive transport model to evaluate the impact of managed aquifer recharge (MAR) on groundwater quality and geochemical processes. The results showed that groundwater geochemistry can be significantly altered during MAR, with nitrate dilution being the main process responsible for observed changes in groundwater quality. Regular monitoring and reactive transport modeling analysis are recommended to minimize the adverse impact of MAR operations on groundwater quality.

Summary: This paper provides a comprehensive overview of using remote sensing techniques for monitoring geomorphology and introduces a new perspective for defining and recording the characteristics of geomorphodiversity using remote sensing data. The five characteristics discussed in this paper are geomorphic genesis diversity, geomorphic trait diversity, geomorphic structural diversity, geomorphic taxonomic diversity, and geomorphic functional diversity. The paper also discusses the challenges and limitations of monitoring geomorphodiversity using remote sensing and presents new approaches and methods for monitoring geomorphodiversity. The importance of the digitization process and data science in geomorphology research is emphasized.

Summary: The goal of this study is to recommend dispersivity values for modeling contaminant transport in groundwater based on a comprehensive analysis of field experiments. The study finds that macrodispersivity coefficients are related to the spatial variability of hydraulic conductivity in groundwater. In the absence of experimental data, practitioners often use ad hoc values for macrodispersivities.

Summary: The Neckar Valley and the Swabian Jura in southwest Germany are hotspots for severe convective storms. A field campaign called Swabian MOSES was conducted to investigate the reasons for the high frequency of thunderstorms and associated event chains. Researchers from various disciplines used a wide range of observation systems, including advanced radar and lidar technologies, to collect data. The study period saw a high number of convective events, and highlights from two intense observation periods are presented in this paper.

Summary: This paper examines the impact of training response variable uncertainty on prediction uncertainties by comparing it with probabilistic prediction obtained using quantile regression random forest. The results provide an uncertainty quantification of the impact on the prediction. The approach is illustrated using the example of probabilistic regionalization of soil moisture derived from cosmic-ray neutron sensing measurements, which produces a regional-scale soil moisture map with data uncertainty quantification for the Selke river catchment in eastern Germany.

Summary: Heavy Precipitation Events (HPE) occur when massive amounts of water vapor are transported to a limited area, leading to floods that can cause damage. By combining mobile and stationary observing systems, we can capture the various processes involved in HPE formation and flooding, such as atmospheric transport, precipitation patterns, and runoff dynamics.

Summary: This paper introduces a mobile wireless ad hoc sensor network (MWSN) concept that automatically records sufficient close-range data to bridge the gap between standardized and available close-range and satellite remote sensing (RS) data. By cross-calibrating the two systems, comparable spectral characteristics of the data sets could be achieved. Additionally, an analysis of the data reveals the influence of spatial and temporal heterogeneity on the data.
