oa Relations between hydrogeologic and geoelectric parameters. A case study: The Setúbal peninsula, Portugal

The Setubal Peninsula is located southern of Lisbon City, in the midst of Portugal (fig. 1). This belt (area) belongs to the Tejo and Sado river basins and it's located between them. It comprises the most important aquifer system of the country. Geohydrological data from the thousand water extraction wells, and more than one hundred Vertical Electric Sounding (VES) surveys exist from that region (fig. 2). Merging of these different data yields better knowledge about constitution and protection of the system.
