Hydrogeological and hydrogeochemical insights on the salinization of the shallow groundwater aquifer in Siwa Oasis – Western Desert – Egypt

Scientific African, 2023
Siwa Oasis is one of the most important Oases in the Western Desert. Groundwater is the only water source. Nubian Sandstone Aquifer is the main supplier of fresh water. Carbonate aquifer is represented by two zones, shallow fracture limestone aquifer and

Hydrogeochemical Evaluation and Health Implications of Groundwater in Magura Sadar Upazila, Bangladesh: Application of GIS and Multivariate Statistics

Journal of Chemistry, Volume 2025, Issue 1, 2025.
Groundwater (GW) quality is a critical factor for its use in drinking and irrigation purpose and has become a significant concern in the southwestern region of Bangladesh. This study aims to conduct an in‐depth hydrogeochemical characterization and assess the suitability of GW for both drinking and irrigation purposes.

Tracing Groundwater‐Surface Water Interactions in a Volcanic Maar Lake Using Stable Isotopes and 222Rn

Journal of Geophysical Research: Biogeosciences, Volume 129, Issue 12, December 2024.
Abstract Isotope hydrological studies to understand groundwater‐surface water interactions in tropical, high‐elevation catchments are limited. These interactions are important in controlling lake water residence time, aqueous biogeochemistry, and water availability for downstream communities and ecosystems. To better comprehend the complexity of spatio‐

Sedimentary dolomite in Western Australia and the dolomite problem: Genesis of channel and playa uranium deposits

Sedimentology, Volume 71, Issue 7, Page 2248-2289, December 2024.
ABSTRACT Quaternary to Recent sedimentary dolomite in groundwater calcrete and saltmarsh sediments of Lake Way and Lake Maitland, Western Australia, provide new information about the formation of low‐temperature dolomite. Dolomite can form through numerous pathways depending on the depositional and diagenetic environment.

Advances in understanding natural groundwater quality controls in coastal aquifers [PDF]

, 2005
Groundwater quality in coastal aquifers is largely influenced by the interaction between the sea and the bordering aquifer systems. This interaction can result in freshening of saline aquifers or salinization of fresh water bodies.

Faulting patterns in the Lower Yarmouk Gorge potentially influence groundwater flow paths [PDF]

, 2019
Recent studies investigating groundwater parameters, e.g., heads, chemical composition, and heat transfer, argued that groundwater flow paths in the Lower Yarmouk Gorge (LYG) area are controlled by geological features such as faults or dikes.

Phreatic overgrowths on speleothems (POS) from the Mallorca caves: Morphology, mineralogy, and crystal fabric classification

Earth Surface Processes and Landforms, Volume 49, Issue 13, Page 4289-4309, October 2024.
An important number of POS (tracers of past seawater levels) sampled from the coastal caves of Mallorca (Spain) have been studied. A systematization has been done according to their morphology, crystal fabric and mineralogy and to their position above or below the current sea level.
