Around the world, coastal groundwater is increasingly subject to seawater intrusion (SWI). The quality and characteristics of such waters differ from those surface groundwater. In current study, trihalomethane (THM) formation under varying levels SWI, natural organic matter (NOM), chloride-to-bromide (Cl/Br) ratio was evaluated. Different SWI were simulated by mixing deionized water with real (...

The possible zones of submarine groundwater discharge (SGD) and seawater intrusion (SWI) along the west coast Kanyakumari in southernmost Indian Peninsula were identified by integrating surface temperature anomaly, water table fluctuation, quality analysis. Temperature map sea from Landsat 8 satellite data, which helped to demarcate SGD areas with significant thermal contrast, exists between di...

We analyze the combined effects of aquifer heterogeneity and pumping operations on seawater intrusion (SWI) in coastal aquifers, a phenomenon which is threatening Mediterranean and worldwide regions. We conceptualize the aquifer as a three-dimensional randomly heterogeneous porous medium, where the spatial distribution of permeability is uncertain. The geological setting of our study is pattern...

Abstract Low‐elevation coastal areas are increasingly vulnerable to seawater flooding as sea levels rise and the frequency intensity of large storms increase with climate change. Seawater can lead salinization fresh aquifers by vertical saltwater intrusion (SWI). Vertical SWI is often overlooked in zone threat assessments despite risk it poses critical freshwater resources salt‐intolerant ecosy...

Many coastal aquifers have experienced seawater intrusion (SWI) into fresh groundwater aquifers. The principal causes of SWI include over-pumping and events such as climate change (CC) rising sea levels. In northern Morocco, the Rmel-Oulad Ogbane aquifer (ROOCA) supplies high-quality for drinking water agriculture. This favorable situation has led to increased pumping, resulting in environmenta...

Seawater intrusion (SWI) is a critical issue for coastal aquifers, especially in islands where groundwater the sole source of water supply. The objective this study was to develop straightforward approach evaluating vulnerability SWI, using statistical method with spatial analyses applied four basins Jeju volcanic island. In study, five factors were parametrized, including hydraulic conductivit...

For managing the freshwater in worldwide coastal aquifers, it is imperative to understand hydrogeochemical processes and flow patterns mixing freshwater/saltwater zone. The Egyptian Nile Delta aquifer a typical example. management of seawater intrusion (SWI) requires detailed investigations wedge dynamic Thus, multidisciplinary approach was applied based on holistic hydrogeochemical, statistica...

BACKGROUND Immersion in seawater after open chest trauma may induce acute lung injury. Higher osmotic pressure is one of the main characteristics of seawater. The effects of vascular endothelial growth factor (VEGF) on endothelial cell permeability and proliferation have been demonstrated in studies. The early responses and effects of the VEGF on acute lung injury induced by seawater immersion ...

In this study, abstraction, desalination and recharge method and SEAWAT numerical model are used to investigate seawater intrusion repulsion in a hypothetical two-dimensional coastal aquifer to understand the relation of seawater intrusion with abstraction, desalination and recharge parameters (i.e. abstraction/recharge rate, wells distance and depth). Abstraction, desalination and recharge con...

Abstract Coastal fresh groundwater management is a challenging research topic due to the relevance of these resources and huge suffered risks global change overpopulation. The geometrical features coastal aquifers play control role in saltwater intrusion (SWI). Seawater level rise reduction aquifer storage are promoting SWI. All key factors considered with two different numerical approaches def...
