Modes of seawater intrusion during transgressions
Analytical methods and numerical experiments are used to study salinization of groundwater in response to sea level rise. The system that is studied involves a saturated porous medium with an inclined upper surface. The upper surface is progressively inundated during sea level rise to simulate transgression, the landward migration of the shoreline. Four "modes" of seawater intrusion are disting...
متن کاملFormal derivation of seawater intrusion models
In this paper, we consider the flow of fresh and saltwater in a saturated porous medium in order to describe the seawater intrusion. Starting from a formulation with constant densities respectively of fresh and of saltwater, whose velocity is proportional to the gradient of pressure (Darcy’s law), we consider the formal asymptotic shallow water limit as the ratio between the thickness and the h...
متن کاملImpacts of seawater rise on seawater intrusion in the Nile Delta Aquifer, Egypt.
Several investigations have recently considered the possible impacts of climate change and seawater level rise on seawater intrusion in coastal aquifers. All have revealed the severity of the problem and the significance of the landward movement of the dispersion zone under the condition of seawater level rise. Most of the studies did not consider the possible effects of the seawater rise on th...
متن کاملDerivation of Seawater Intrusion Models by Formal Asymptotics
In this paper, we consider the flow of fresh and saltwater in a saturated porous medium in order to describe the seawater intrusion. Starting from a formulation with constant densities respectively of fresh and saltwater, whose velocities are proportional to the gradient of pressure (Darcy’s law), we consider the formal asymptotic limit as the aspect ratio between the thickness and the horizont...
متن کاملSeawater Intrusion in the Plain of Oristano (sardinia, Italy)
The site under study covers an area of 273 km in the Oristano plain on the west coast of Sardinia (Italy). Since 1950 the plain, formed during the Quaternary by alluvial deposits, has been under intensive cultivation and is an important dairy farming centre. In the coastal region, the large number of wells (25,000 tapped and not) some very close to each other, has resulted in over-exploitation ...
