Training course on geophysics and geoelectric resistivity method, Médenine, Tunisia, April 07th – 12th 2014

Within the geo-electrical campaign carried out in Medenine (Tunisia) between the 07th – 12th April 2014, a training course was organized  in order to provide the basic principles of the electrical resistivity method and the galvanic coupled resistivity system aiming at the production of 2D resistivity tomographies for the definition of the stratigraphy of the area and the related saturation condition of the subsoil.

The training was attended by 12 participants and was divided into two sessions, a theoretical one (two day course) and a training in the fields of Oued Naggueb,  Oued Gettar – Oued Arniane and Oued Jani – Oued Arniane. Lectures on electrical resistivity method and data processing were provided as follows:
Day 1: lecture on electrical resistivity method - Objective where to provide the basis on the theory of the geoelectric resistivity method and to analyse the physical parameters controlling the rocks and soils conductivity. Main electrode arrays employed for geological studies have been described. The device Abem Terrameter SAS1000 Lund Imaging System and field procedures have been also illustrated. Finally, specific case studies and success stories have been presented to show the potential application of the electrical resistivity tomography.
Day 2: data processing - Objective: Use of Res2Dinv ver. 3.4 (Geotomo software) for data processing; analyses of the main inversion parameters and post-processing of the data.
All lectures have been presented in PowerPoint format, and documents and hands-on provided to all participants. Data processing has been performed on personal computers of each attendant to the course.
Field based operations and training lectures have been directed by Prof. Giorgio Ghiglieri,  Dr. Claudio Arras, Dr. Stefano Cuccuru, Dr. Vittorio Longo and Dr. Valeria Testone of the University of Cagliari (Italy) and University of Sassari (Italy) with the support of IRA (Tunisia) technicians attending this session and belonging to the WADIS-MAR Project Partnership.
