Role of the clay lenses within sandy aquifers in the migration pathway of infiltrating DNAPL plume: A numerical investigation [PDF]
arXiv, 2023 The use of numerical based multi-phase fluid flow simulation can significantly aid in the development of an effective remediation strategy for groundwater systems contaminated with Dense Non Aqueous Phase Liquid (DNAPL). Incorporating the lithological heterogeneities of the aquifer into the model domain is a crucial aspect in the development of robust ...

Evaluation of climate change effects in a coastal aquifer in Morocco using a density-dependent numerical model [PDF]
, 2010 A density-dependent numerical groundwater model was applied to study the climate change impact in a shallow aquifer in the Mediterranean coast of Morocco, the Saidia aquifer. The stresses imposed to the model were derived from the IPCC emission scenarios

Managed Aquifer Recharge (MAR) in Sustainable Urban Water Management
, 2018 To meet increasing urban water requirements in a sustainable way, there is a need to diversify future sources of supply and storage. However, to date, there has been a lag in the uptake of managed aquifer recharge (MAR) for diversifying water sources in ...

Effects of aquifer geometry on seawater intrusion in annulus segment island aquifers [PDF]
Hydrology and Earth System Sciences, 2021 Abstract. Seawater intrusion in island aquifers was considered analytically, specifically for annulus segment aquifers (ASAs), i.e., aquifers that (in plan) have the shape of an annulus segment. Based on the Ghijben–Herzberg and hillslope-storage Boussinesq equations, analytical solutions were derived for steady-state seawater intrusion in ASAs, with a

Dispersion of a fluid plume during radial injection in an aquifer [PDF]
, 2021 This study outlines a model for injected fluid flow in a vertically confined porous aquifer with mechanical dispersion. Existing studies have investigated the behaviour and geometry of immiscible fluid flow in this setting, where the injected fluid displaces the resident fluid, forming a sharp interface between the two.

Numerical Simulation of Bijar-Divandere Plain Aquifer Using MODFLOW Code and Investigation in The Effects of Drought on Its Quantitative Changes [PDF]
محیط زیست و مهندسی آب, 2022 In this study, quantitative changes in groundwater in Bijar-Divandere plain with MODFLOW code in GMS software were investigated. Aquifer simulation was performed for a period of six years and a monthly step from October 2010 to June 2016.

Structural and hydrogeological features of a Lias carbonate aquifer in the Triffa Plain, NE Morocco [PDF]
, 2012 The rising demand for water and the contamination of shallow water table aquifers has led authorities in NE Morocco to look for deeper groundwater resources in the Triffa Plain, namely in Lower Jurassic (Lias) dolomitic limestones. The liassic aquifer is

Aquifer Arsenic Cycling Induced by Seasonal Hydrologic Changes within the Yangtze River Basin.
Environmental Science and Technology, 2016 Consumption of groundwater containing >10 μg L(-1) arsenic (As) adversely impacts more than 100 million people worldwide. Multiyear trends in aquifer As concentrations have been documented, but strong seasonal variations are not commonly observed.
