Geophysical And Hydrogeological Studies In A Coastal Plain Affected By Salt Water Intrusion

Gravity, electrical and reflection seismic surveys, along with classical hydrogeological<br>investigations, were carried out in a coastal plain affected by salt water intrusion, within<br>the framework of a project aimed at constructing a structural and hydrogeological model<br>of the area. Hydrogeological investigations provide data necessary for characterizing the<br>aquifers at a depth of a few tens meters and show the zone of high contamination.<br>Gravity surveying allowed the depth to the basement to be estimated and hence the<br>thickness of sediments and alluvium. Electrical and seismic reflection surveys proved<br>to be effective tools for recognizing deep aquifer characteristics and the complex<br>stratigraphic structure of the plain.
