“…Evaporation is a key component of groundwater drainage and contributes to the fluctuation of the groundwater table (Figure 1). 28,29 The monthly evaporation loss of 916 reservoirs in China increased significantly for 33 years, and the total loss of evaporation reached 140.2 × 10 8 m 3 in 2018, which provided the evidence that evaporation played a non-negligible role in controlling the 29 rainfall, 32 tide, 40 lateral recharge and drainage, 47 surface water, 49−51 irrigation, 63,64 and groundwater pumping 68 ). There is a mixing zone between freshwater and seawater in a coastal aquifer, and salinity drives high-salinity seawater into freshwater aquifers.…”

The groundwater table fluctuation (GTF) zone is an important medium for the hydrologic cycle between unsaturated soil and saturated aquifers, which accelerates the migration, transformation, and redistribution of contaminants and further poses a potential environmental risk to humans. In this review, we clarify the key processes in the generation of the GTF zone and examine its links with the variation of the hydrodynamic and hydrochemistry field, colloid mobilization, and contaminant migration and transformation. Driven by groundwater recharge and discharge, GTF regulates water flow and the movement of the capillary fringe, which further control the advection and dispersion of contaminants in soil and groundwater. In addition, the formation and variation of the reactive oxygen species (ROS) waterfall are impacted by GTF. The changing ROS components partially determine the characteristic transformation of solutes and the dynamic redistribution of the microbial population. GTF facilitates the migration and transformation of contaminants (such as nitrogen, heavy metals, non-aqueous phase liquids, and volatile organic compounds) through colloid mobilization, the co-migration effect, and variation of the hydrodynamic and hydrochemistry fields. In conclusion, this review illustrates the limitations of the current literature on GTF, and the significance of GTF zones in the underground environment is underscored by expounding on the future directions and prospects.

“…This water is considered recharge since the depth‐to‐water table is within 1–6 m below the model boundary. Principally, recharge may also occur via infiltration of surface waters into an aquifer (Gumula‐Kawecka et al, 2022). However, at our study site no surface water bodies are present so that our assumption to focus on soil water infiltration is sound.…”

“…The first year of each simulation (1970) was considered as a 'spin-up' run to let the soil water in the model equilibrate at an initial stage (Gumula-Kawecka et al, 2022). The results of the first year of each run was therefore always discarded from further analysis.…”

The fraction of precipitation that infiltrates soils and subsequently becomes recharge is one of the principle components of an unconfined aquifer's water budget (this fraction is here termed recharge efficiency). Here we tested how recharge efficiency will respond to climate change including a possible plant physiological response to climate change (e.g., stomatal closure; increasing leaf area) in a catchment used for drinking water production in western Germany. To this end we used a soil water model (HYDRUS‐1D) forced with climate data spanning the time period from 1971 to 2099. Three different vegetation types were considered: turf grass representing the primary infiltration sites within residential areas; maize representing the main crop on agriculturally used land; and beech representing the forested parts of the catchment. We found that, the positive effects of climate change on recharge efficiency (more rain during the main recharge season in winter, less crop water demand due to faster plant ripening in spring and summer, increased plant water use efficiency, reduced global radiation as cloud density increases) were not completely compensated by the negative effects (less precipitation, higher leaf area index and increasing vapour pressure deficit in summer season) at our study site. Because total annual precipitation increased slightly until the end of the 21th century, changes in the amount of total annual recharge were also positive, though moderate (up to +20% change in the period 2071–2099 as compared to 1970–2000). The results of this study will be helpful for water authorities managing water rights under the perspective of a changing climate. In the future, our study site is expected to receive sufficient recharge from precipitation to maintain current rates of groundwater withdrawal for public water supply and irrigation. Thus, the region's agriculture sector may become a ‘global warming winner,’ when cropping in other regions in Europe may increasingly suffer from drying conditions during the growing season.

“…This approach produces recharge estimates that compare well other methods when the water table elevation varies smoothly and aquifer properties are relatively well known (Cuthbert, 2010). The water table fluctuation method requires the specific yield as the only parameter (Gumuła‐Kawęcka et al, 2022). However, such a quantity is difficult to determine, as it depends on the type of soil, depth to the groundwater table, and water dynamics in the vadose zone (Healy & Scanlon, 2010).…”

Water table elevation is a key feature for identifying the groundwater behaviour. Accordingly, appropriate measurements—in terms of both frequency and spatial distribution—play a crucial role for capturing the aquifer response to recharge and withdrawals. However, numerical models simulating the main features of the behaviour of the water table elevation may help groundwater management, as an additional tool. In this article, soil moisture data from three well‐established global reanalyses (ERA5, CFS, and JRA‐55) are used for evaluating the flux in the vadose zone towards shallow unconfined aquifers, Fg$$ {F}_g $$, in the Umbria region (central Italy). Then, according to the methodology proposed in Bongioannini Cerlini et al. (2021), where for the considered aquifers most of the recharge derives from the unsaturated zone, Fg$$ {F}_g $$ is used for simulating the water table evolution in time. With the aim of assessing which reanalysis is the most appropriate in simulating the evolution of groundwater levels, the properties of the correspondent land surface models (LSM) are examined, as they provide Fg$$ {F}_g $$. For the considered aquifers, the analysis of the performance of the selected reanalyses confirms the validity of the proposed approach. Moreover, it points out the crucial role of the spreading of the water table elevation with respect to its mean value, as a significant parameter for selecting the most adequate reanalysis to use. In addition, the role in the LSM of the explored soil depth, hydraulic conductivity curve, and spatial resolution is highlighted. These results, in line with recent literature on the performance of the reanalyses, suggest to extend future work to other regions of the world.
