Special Issue Information

Dear Colleagues,

This Special Issue on “Groundwater Hydrology Research” focuses on recent advances and progress in groundwater studies. Human activities and the impact of climate change on the water environment cause a permanent increase in the importance of good-quality groundwater. Therefore, the efforts of hydrogeologists focus on the study of groundwater recharge, flow, and drainage processes in pore, fissure, and karst systems. Quantitative assessments aim to ensure that residents have access to sufficient amounts of water, while qualitative research and constant monitoring must secure the supply of drinking water. The above being the case, the challenges faced by water researchers continue to increase with population growth and environmental pollution problems. In different parts of the world, approaches to environmental protection vary, so the exchanging of experience becomes very important.

We organize this Special Issue to call on colleagues to present the latest achievements in the field of the recognition of complex hydrogeological conditions in terms of resource assessments as well as the protection and quality of groundwater, with particular emphasis on new field/laboratory techniques, innovative instrumentation, and numerical modeling. By presenting this integrative and multidisciplinary volume, we would like to emphasize the complexity of the processes governing the flow of groundwater in order to indicate assumptions for the sustainable development of groundwater resources.

China has implemented a series of ecological protection and restoration projects in Tianshan Mountain and Yili Valley in Xinjiang, which have significantly improved regional vegetation coverage. Vegetation improves soil structure through roots, especially increasing non-capillary porosity, which enhances the precipitation infiltration performance, thus reducing surface runoff, increasing the interception and infiltration of groundwater resources, and enhancing regional water retention capacity of soil. In order to quantitatively study the impact of ecological conservation and restoration (represented by fraction of natural vegetation coverage, FVC) on groundwater storage (GWS), we investigated GWS changes in this region, identified the main factors, and quantified their relative impacts. Here, we combined data from the Gravity Recovery and Climate Experiment (GRACE) satellite, GRACE Follow-On (GRACE-FO), and Global Land Data Assimilation System (GLDAS) hydrological model from January 2003 to December 2020 and evaluated GWS changes. We used the variable importance in projection and partial least squares regression methods to determine the main influencing factors. We found that (1) before and after 2012, GWS decreased at a rate of 0.80 cm/yr and 0.75 cm/yr (with statistical significance p < 0.01), respectively. (2) Before 2012, the main factors affecting the decrease in GWS were agricultural planting areas, and after 2012, they were temperature, evaporation, and FVC, with relative contributions of 54.72%, 34.59%, and 10.69%, respectively. FVC has a positive regulating effect on the increase in regional GWS. Full article

As far as we know, universal solutions (or type-curves) for scenarios of flow through anisotropic unconfined aquifers due to pumping wells cannot be found in the literature. On the contrary, those theoretical solutions in hydrogeological manuals are commonly based on Dupuit solutions for isotropic soils or simplifying other characteristics of the chosen medium. In this study, the application of the discriminated nondimensionalization technique allowed for the inclusion of vertical and radial hydraulic conductivities in the data set, with which the monomials ruling unknown variables of the problem, pumping flow and seepage surface in their dimensionless form are obtained. One of the main findings of this research is depicting these relationships as type-curves from a large number of precise numerical simulations based on the Network Simulation Method. The other main finding is an easy-to-apply methodology to estimate vertical and radial hydraulic conductivities employing these type-curves. This methodology can be considered as an inverse problem. In addition, an example of the problem is presented, in which the influence that measure deviations may have on the estimated values of the hydraulic conductivities in anisotropic soils is also studied and discussed.
