Managed aquifer recharge and changes in crop type or nutrient management on agricultural lands are promising approaches to address groundwater quality degradation by nitrate. Tools to assess nonpoint-source contaminant transport are needed to better understand the interaction between agricultural management practices and long-term nitrate dynamics in groundwater basins. This study investigates the impact of time-resolution upscaling of groundwater flow stresses (i.e., recharge, pumping, and evap...

The small islands in the Mediterranean Sea suffer water shortages, aggravated by pressure from tourism during the dry season. Many are affected by the intense and increasing human water demand and the harsh climatic and geographic nature of the island terrain. The present study, carried out on the island of Favignana, Egadi Archipelago (southern Italy), evaluates the regime of recharge to the subsurface, and hypothesizes a solution for identifying the areas where groundwater is most abundant, as...

The influence of lunar semidiurnal tides on coastal groundwater aquifers has been conceptualized for decades. However, a thorough understanding of the impact of tides on groundwater dynamics due to the widely distributed waterways and heterogeneous sediments in estuarine aquifers, is still needed. This study shows the tidal impact on groundwater dynamics in the Pearl River estuary in southeast China through wavelet and time series analysis. The groundwater level and electrical conductivity (EC),...

Simulation optimization is a robust tool in the design of groundwater remediation strategy. Simulation models for groundwater contaminated by dense non-aqueous phase liquids (DNAPLs) are usually computationally expensive, especially when used within a simulation optimization framework. Surrogate models have been proved to possess the potential to speed up complex models without sacrificing accuracy or detail. In this study, a constrained trust region (CTR)-based adaptive dynamic surrogate model ...

A cold-region watershed located in the discontinuous permafrost zone near Umiujaq (Nunavik, Canada) was studied in order to increase understanding of the subarctic water cycle and permafrost dynamics. This essay gives an overview of the research, summarised in a collection of six papers that: respectively characterize the physical three-dimensional cryo-hydrogeological system, present a detailed water balance of the watershed, characterize groundwater and surface-water hydrogeochemistry, describ...

For the quantitative evaluation of the impact of mining on a groundwater system, it is necessary to constrain the hydrogeological and mechanical properties. However, the in situ estimation of the mechanical properties of rock such as compressibility and porosity, is often difficult. Additionally, determining the hydraulic properties such as hydraulic conductivity, of rock by conventional methods is often expensive. The response of the groundwater level to external loading such as Earth tides and...

The karst hydrogeology systems of the Watuputih Hills region of Central Java, Indonesia, have many springs with varying discharge and are composed of formations with complex geological structures. This work characterized the karst hydrogeology by studying 50 hydrogeological features (caves, springs and wells) and by analyzing the chemical-physical properties of groundwater in the field (pH, temperature, EC, HCO3−, 222Rn) and the major ions and stable isotopes of the groundwater samples in the la...

Seismic waves can influence subsurface fluid and mass transport and can be used for aquifer remediation, carbon dioxide sequestration, and oil production. The influence of particle size on transport was investigated using three particle-size classes in sand-column experiments. For each size class, three flow rates and five ultrasonic powers were used to examine the roles of hydrodynamic force and ultrasonic stimulation. The number of particles captured in porous media (by straining, wedging, fou...

The effect of an aquitard above a leaky aquifer on retarding characteristic pollutants is very important for evaluating groundwater vulnerability. A case study is presented of the leaky aquifer in the Tongzhou Plain of China. On the basis of analyses of the environmental and hydrogeological characteristics of the study area, an indicator system to evaluate the leaky aquifer’s vulnerability was constructed, comprising eight indicators: the depth to groundwater (D), the net recharge (R), the impac...

Improving water availability and distribution is key to combatting water stress in semi-arid regions. This study presents an approach that integrates hydrogeological surveys and economic analysis at a pilot site in the eastern Lower Jordan Valley to assess the potential for managed aquifer recharge (MAR). Based on exploratory drillings, hydraulic tests, water-quality analyses and previous studies, an appropriate storage space in the alluvial fans along the eastern margin of the valley was found....
