Salt-water intrusion (SWI) is a worldwide problem increasingly affecting coastal aquifers, exacerbated by climate changes and growing demand of fresh-water. Therefore, research on this topic using both physical numerical modeling has been intensified, aiming to achieve better predictions the salt-water wedge evolution design suitable countermeasures its negative effects. This work presents labo...

Five periods of increased electrical conductivity have been found in the karst conduits supplying one of the largest first magnitude springs in Florida with water. Numerous well-developed conduit networks are distributed in the Woodville Karst Plain (WKP), Florida and connected to the Gulf of Mexico. A composite analysis of precipitation and electrical conductivity data provides strong evidence...

[1] The classic Ghyben‐Herzberg estimate of the depth of the freshwater‐saltwater interface together with the Dupuit approximation is a useful tool for developing analytical solutions to many seawater intrusion problems. On the basis of these assumptions, Strack (1976) developed a single‐potential theory to calculate critical pumping rates in a coastal pumping scenario. The sharp interface assu...

Numerical modeling applications in hydrogeology range from pore scale to global simulations, and help quantify fluid and solute transport dynamics in variably saturated, multi-permeability, and multiphase systems. Simulations of flow are essential for addressing issues of fundamental hydrologic science, and even more so for developing and testing management or remediation strategies. Numerical ...

We study a seawater intrusion problem in a confined aquifer. This process can be formulated as a coupled system of partial differential equations which includes an elliptic and a degenerate parabolic equation. Existence results of weak solutions, under realistic assumptions, are established through time discretization combined with parabolic regularization.

Freshwater resources in coastal areas are under intense pressure from excessive groundwater extraction, which amplifies saltwater intrusion (SWI) into freshwater aquifers, such as the Mekong Delta. Studies that combine socioenvironmental data and households’ psychological factors next to salinity measurement design conservation strategies rare. In this study, these aspects combined explore thei...

A multidisciplinary study involving hydrogeochemical sampling and borehole geophysics was undertaken to study the nature and occurrence of saline groundwater on two islands in British Columbia, Canada. Saturna and Hornby Islands are located at the south and north ends, respectively, of the Canadian Gulf Islands situated off the lower mainland of British Columbia. Two large-scale geochemical sam...

Abstract Seawater intrusion and drinking-water fluorosis are frequently documented along coastal plains. Groundwater is characterized by high OH−, Na+, total dissolved solids, low Ca2+ because of seawater intrusion, such conditions favor sediment fluoride-leaching fluorosis. But the geological process has not been noticed when high-fluoride groundwater areas discussed. The sediments in a typica...
