First results of waterborne geophysical surveys around the Malpasso site (Tuoro sul Trasimeno, Italy) for geological and archaeological characterization

Geological characterization of shallow sediments in water-covered areas is a difficult task with traditional survey techniques. Geophysical techniques can be very useful to investigate sediments which are entirely located beneath a water-covered area. With the aims of both reconstructing the geological setting of the area around the Malpasso site (Tuoro sul Trasimeno, Italy) and eventually localizing some archeological remains of the Trasimeno battle (217 BC) we carried out several waterborne geophysical surveys on the area. Adopted methodologies were: magnetic surveys, seismic reflection profiles and Continuous Vertical Electric Soundings (CVES). Within this paper we report some preliminary results for the last two methodologies underlining the main evidences observed and further planned processing and data integration.
