Review: Advances in the methodology and application of tracing in karst aquifers Hydrogeol. J. (IF 2.641) Pub Date : 2021-01-20 Ralf Benischke
Tracer methods have been widely used in many fields of environmental and natural sciences, and also in human health sciences. In particular, tracers are used in the study of karst hydrogeology, typically focusing on phenomena such as sinkholes, sinking rivers and large karst springs. It is known that tracers have been used since antiquity. The aim of tracer tests has been to investigate underground

Diagnosing the subsurface buffer on ground-surface temperature under long-term groundwater pumping: effects of the bottom boundary condition placement Hydrogeol. J. (IF 2.641) Pub Date : 2021-01-19 Chen Yang, Tingting Zheng, Kun Huang, Zheng Lu, You-Kuan Zhang, Xiaofan Yang
The terrestrial subsurface acts as a buffer in regulating land-surface water and energy processes. In integrated modeling with land-surface models, the regulating capacity of the subsurface is largely determined by the bottom boundary condition placement (BBCP). However, the sensitivity of land-surface processes to BBCP in Earth system modeling and integrated hydrologic modeling under conditions of

Karst-aquifer operational turbidity forecasting by neural networks and the role of complexity in designing the model: a case study of the Yport basin in Normandy (France) Hydrogeol. J. (IF 2.641) Pub Date : 2021-01-09 Michaël Savary, Anne Johannet, Nicolas Massei, Jean-Paul Dupont, Emmanuel Hauchard
Karst aquifers are highly susceptible to pollution transport, particularly turbidity, because these aquifers do not filter water to any significant degree. This may occasionally induce sanitary issues for the population and, therefore, it is operationally important to predict the mobility of water with high turbidity. In this study, deep specific architectures, recurrent and feed-forward, inspired

Dams and reservoirs in karst? Keep away or accept the challenges Hydrogeol. J. (IF 2.641) Pub Date : 2021-01-09 Petar Milanović
The distribution and flow of groundwater in karstified rocks can be extremely complex and not readily predictable, a far from friendly environment for constructing dams and reservoirs. There have been many expensive failures such as unacceptable leakage rates at and around dams, and/or reservoirs that could not be filled to the design levels. This is never the fault of site geology but always of human

Single-borehole dilution tests (SBDTs) are a method for characterizing groundwater monitoring wells and boreholes, and are based on the injection of a tracer into the saturated zone and the observation of concentration over depth and time. SBDTs are applicable in all aquifer types, but especially interesting in heterogeneous karst or fractured aquifers. Uniform injections aim at a homogeneous tracer

The Bayesian approach is attractive because it can consider various uncertainties in the inverse process. Although the Bayesian algorithm has strong random ergodicity, it still lacks the ability to perform local optimization. Therefore, an improved single-component adaptive Metropolis (SCAM) algorithm based on Bayesian theory was developed to solve this problem and it was applied to the simultaneous

In southwestern Bangladesh, clean drinking water is scarce, since rainwater is only available during the monsoon, pond water is often bacteriologically polluted, and groundwater may exhibit high salinity and arsenic levels. Managed aquifer recharge (MAR) might potentially provide safe drinking water by storing abundant freshwater from the wet season in aquifers for year-round use. Regional potential

Float-laser device for measuring the water table and freshwater–saltwater interface in laboratory-scale experimental systems Hydrogeol. J. (IF 2.641) Pub Date : 2020-11-07 Byunghee Nam, Adrian D. Werner, Namsik Park
Processes in coastal aquifers involving variable-density fluids are often investigated using laboratory sand tanks. However, experimental monitoring of the interface between liquids of different densities is challenging, typically requiring dye tracers and photographic analysis. These are susceptible to problems of tracer adsorption and image inhomogeneity, and experiments are often limited to two-dimensional

Effects of non-isothermal flow on groundwater recharge in a semi-arid region Hydrogeol. J. (IF 2.641) Pub Date : 2020-08-06 Zaiyong Zhang, Wenke Wang, Chengcheng Gong, Ming Zhao, Zhoufeng Wang, Haizhen Ma
Groundwater recharge is critical to water circulation in arid and semi-arid regions. The accurate determination of groundwater recharge is required for assessing water resources and effectively managing groundwater, especially in water-limited areas. Based on field experiments and numerical models in a semi-arid region, this study assessed the effect of non-isothermal flow on groundwater recharge.

Hydraulic characterization of a highly anthropized coastal aquifer subject to tidal fluctuations Hydrogeol. J. (IF 2.641) Pub Date : 2020-08-04 P. Fischer, A. Jardani, M. Krimissa, C. Couegnas
The hydraulic characterization of a highly anthropized coastal aquifer in France is presented. The current industrial operations of the study site prevent the use of standard ‘active’ hydrogeological investigation methods (pumping, slug tests). However, the studied field is bordered on its north-western side by a channel directly connected to the sea, which allows for characterization of the hydraulic

Global sensitivity analysis on a numerical model of seawater intrusion and its implications for coastal aquifer management: a case study in Dagu River Basin, Jiaozhou Bay, China Hydrogeol. J. (IF 2.641) Pub Date : 2020-07-31 Di Zhang, Yun Yang, Jianfeng Wu, Xilai Zheng, Guanqun Liu, Xiaomin Sun, Jin Lin, Jichun Wu
Seawater intrusion (SWI) has triggered an accelerating process of freshwater contamination and significantly affected the soil fertility and local groundwater supply in the coastal area of Jiaozhou Bay, Shandong Province, China. This study establishes a three-dimensional numerical model based on SEAWAT code to simulate transient regional SWI to coastal aquifers in Dagu River Basin (DRB) adjacent to

Estimating the specific yield of the Pampeano aquifer, Argentina, using superconducting gravimeter data Hydrogeol. J. (IF 2.641) Pub Date : 2020-07-31 Jonatan E. Pendiuk, Luis Guarracino, Marvin Reich, Claudio Brunini, Andreas Güntner
Specific yield is a key parameter for the sustainable management of unconfined aquifers, since it relates water-table fluctuations to aquifer storage-changes and thus impacts water supply. However, estimating specific yield is still a challenge due to theoretical and methodological limitations. Water-storage changes in the aquifer and in the overlying unsaturated soil profile cause local changes in

An empirical porosity–depth model for Earth’s crust Hydrogeol. J. (IF 2.641) Pub Date : 2020-07-23 Jianxin Chen, Xingxing Kuang, Chunmiao Zheng
Porosity is one of the most basic physical properties of a stratum. Previous studies have shown that porosity generally decreases with depth. There are five main types of empirical models available for describing such a porosity–depth relationship: the linear model, the exponential model, the power law model, the reciprocal model, and the parabolic model. For the majority of past and existing studies
