In this paper, a technique to restore the balance between freshwater and saline water in coastal aquifers in order to mitigate seawater intrusion problems is presented, where brackish water can be pumped from the dispersion zone and then used to develop green lands in coastal areas or to irrigate certain types of crops.Abstract:
This paper presents a technique to restore the balance between freshwater and saline water in coastal aquifers in order to mitigate seawater intrusion problems. Brackish water can be pumped from the dispersion zone and then used to develop green lands in the coastal areas or to irrigate certain types of crops. A two-dimensional finite element model (2D-FED), has been employed to verify this technique. The model is based on the dispersion zone approach with a variable density flow. Simulations were preformed in the vertical view and equiconcentration and equipotential lines were plotted for different locations of brackish water pumping. In all of the tested runs the width of dispersion zone has reduced significantly due to brackish water pumping. The quality of the pumped water differs according to the location of pumping. A study case on the Madras aquifer in India is presented.read more

Geochemical and isotopic evidence for palaeo-seawater intrusion into the south coast aquifer of Laizhou Bay, China
TL;DR: Li et al. as discussed by the authors improved the current knowledge of groundwater salinisation processes in coastal aquifers using combined hydrochemical and isotopic parameters and inverse hydrochemical modelling. But their work was limited to three sampling campaigns along a vertical transect in the ChangyiLiutuan area, 95 ground and surface-water samples were collected for major ion and isotope analysis.

Seawater intrusion in coastal aquifers : concepts, methods, and practices
TL;DR: In this paper, a semi-Empirical approach to intrusion monitoring in Israeli Coastal Aquifer is presented, based on a three-dimensional model of Coupled Density-Dependent Flow and Miscible Salt Transport, and the Modified Eulerian Lagrangian Method for Density Dependent Miscible Transport.
SUTRA (Saturated-Unsaturated Transport). A Finite-Element Simulation Model for Saturated-Unsaturated, Fluid-Density-Dependent Ground-Water Flow with Energy Transport or Chemically-Reactive Single-Species Solute Transport.
TL;DR: SUTRA as mentioned in this paper is a computer program which simulates fluid movement and the transport of either energy or dissolved substances in a subsurface environment, which employs a two-dimensional hybrid finite-element and integrated-finite-difference method to approximate the governing equations that describe the two interdependent processes that are simulated by SUTRA.
