Geophysical prospection of an archaeological site (Grand, France): Characterization of a hydraulic system in a karstic context

The application of geophysical methods for the detection of archaeological features is well-established nowadays. Geophysical surveying is the investigation of shallow subsurface layers with non-destructive tools to obtain quickly information on buried structures without harming these structures. Moreover, excavations, sometimes expensive and disappointing, can frequently be avoided as a result. The paper is a case study of a Gallo-Roman site and the results of the latest geophysical prospect...
