Ground penetrating radar and electrical resistivity tomography investigations in the southern sector of the Roman Forum. First results on the pre-Augustan phases of the Basilica Julia

A research project aimed at the study of the archaeological context of the Basilica Julia in the Roman Forum (Rome, Italy) and the transformation phases of the building involved the use of different techniques of geophysical prospecting. In particular, Ground-penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT) surveys were carried out in order to record the buried structures of the Basilica and the previous buildings laying in the southern part of the Forum.

Three-dimensional reconstruction of a masonry building through electrical and seismic tomography validated by biological analyses

In this paper, we present an integrated approach, for assessing the condition of an ancient Roman building, affected by rising damp and cracking phenomena. The combination of high-resolution geophysical methods, such as seismic and electrical tomography, with biological information, allowed a more detailed evaluation of the state of conservation of the masonry building. A preliminary three-dimensional electrical survey was conducted to detect the existing building foundations and to determine the variation of the resistivity in the ground.
