Rizzo 1;2 1 Dipartimento di Fisica e Scienze della Terra, Università di Ferrara, Italia 2 CNR-IMAA, Laboratorio Hydrogeosite, Marsico Nuovo-Tito, Italia In the last decade, the Applied Geophysics was intensively used in urban area where an indirect approach is necessary due the presence of large number of people and the cities are starting to be metropolises. The increase of the metropolises stresses the urban areas and intensive planning works is necessary. To date, more than half of the world’s population lives in large cities and these numbers will increase more and more. In fact, it is expected that in 2050 the number of metropolises will increase and 66% of the population will live in urban areas (UNDESA, 2014). Therefore, the development of new technologies and methodologies able to explore the subsoil and manage its resources in urban areas becomes an important source in terms of saving time and money. The paper of Lapenna V. (2017) defines this concept introducing the Urban Geophysics, which analyses the contribution, in terms of limits and potentialities, that geophysical methodologies can give for providing useful information about the subsoil, environment, buildings and civil infrastructures and supporting the public administrations in planning interventions in urban scenarios. The first part of this work introduces a laboratory test, that was performed at the Hydrogeosite CNR-IMAA laboratory of Marsico Nuovo (Basilicata region, Italy). The test consisted in a multisensor geophysical application on an analogue engineering model (Fig.1). Thanks to the possibility to work in laboratory conditions, a detailed knowledge of the structure was available, providing great advantages for assess the capability of the geophysical methodologies for analyse engineering issues, regarding the characterization of the infrastructural critical zone placed at the Fig. 1 - Analogue engineering model.
