Abstract

The paper refers about combined geophysical and hydrogeological surveys carried out in a coastal plain in SW Sardinia (Italy). Concerning geophysical methods, reflection seismology, electrical resistivity soundings and TDEM were applied. These surveys confirm, with a high detail level, that the aquifers of the plain constitute a complex, multilayer system and that in the middle of the plain, due to presence of of thick impermeable Miocene materials, the probability of finding fresh water at a depth of less than 350-400 m is very low.
