Coastal Aquifers and Saltwater Intrusion

2008
As a large portion of the world's population (e.g. about 70%) dwells in coastal zones, sustainable and optimal coastal aquifer exploitation that controls saltwater intrusion is necessary. Especially in coastal zones, groundwater over- exploitation has disturbed the naturally established equilibrium between saltwater and freshwater which has resulted in

Contaminant transport in coastal aquifers

2009
Coastal aquifers are distinguished from other aquifers because of tidal effects which cause complicated groundwater flow and contaminant transport phenomena in regions immediately adjacent to the coast. This study is designed to address the significance of tidal influence on contaminant transport by focusing on one-dimensional homogeneous coastal ...

Groundwater ages in coastal aquifers

Advances in Water Resources, 2013
The interpretation of groundwater ages in coastal aquifers requires an improved understanding of relationships between age distributions and the processes accompanying dispersive, density-dependent flow and transport. This study uses numerical modeling to examine the influence of mixing and a selection of other hydrogeological factors on steady-state ...

Contaminant transfer in coastal aquifers

2009
Groundwater flow and contaminant transport processes in coastal aquifers can be complicated by tidal effectsadjacent to the coast. This study was designed to evaluate the significance of tidal influences on contaminanttransport by focusing on one-dimensional homogeneous coastal aquifers.

Coastal aquifers of Europe: an overview

Hydrogeology Journal, 2009
Europe has a long coastline along which many human activities are concentrated. Coastal aquifer development is often intensive and subject to salinity problems as a result of seawater intrusion, upconing of deep saline water, and residual salinity in aquitards.

On seawater encroachment in coastal aquifers

Water Resources Research, 1974
The seawater encroachment in a coastal aquifer is studied by means of a mathematical model. In some aquifers the dispersion amalgamates the encroaching seawater and the discharging freshwater to produce an extensive zone of diffusion. The coupled nonlinear conservation equations of mass and of salt are formulated and solved by the finite element method

Moving Interface in Coastal Aquifers

Journal of the Hydraulics Division, 1964
The movement of the interface between fresh water and sea water in coastal aquifers caused by changes in seaward flow of fresh water is considered. Approximate solutions to the moving interface, its shape, position, and velocity of displacement are suggested.

Analytical approximation for tidal dynamics in coastal aquifers

2003
Recently, considerable effort has been devoted to the studies of water-table fluctuations in coastal aquifers. However, most previous investigations have been based on one-dimensional models that describe the processes in the cross-shore direction alone, assuming negligible along shore variability.
