Inversion strategies for seismic surface waves and time-domain electromagnetic data with application to geotechnical characterization examples.
Geophysical methods are broadly used to map the subsurface. Their ability to investigate large areas in a short time and to reach significant depths with good resolution makes them suitable for a wide range of applications: from hydrological studies, mineral exploration, archaeological …

LAKEMAGING: GEOPHYSICAL DATA INTEGRATION FOR GROUNDWATER MODELLING
Groundwater models are often affected by strong uncertainties because hydrogeological information is commonly derived from sparse boreholes, local hydraulic tests, and indirect observations that do not adequately describe subsurface heterogeneity. In this context, geophysical methods, and …

DEVELOPMENTS IN E&EM GEOPHYSICS:JOINT INVERSION, TIME-SERIES ANALYSIS AND SYSTEM CALIBRATION
The research presented in this Ph.D. thesis stemmed from the largest Airborne Electromagnetic (AEM) campaign ever conducted in Italy between 2021 and 2023, and from the specific challenges arising from this project. The campaign aimed to investigate the geological and hydrogeological architecture …

Surface Wave Analysis in Laterally Varying Media
This work studies the possibility of using surface wave analysis as a tool for a robust estimation of the S-wave velocity behaviour in laterally varying media. The surface wave method, in fact, can be effectively adopted for different purposes and at different scales, but I focused on the …

Seismic reflection imaging of near surface structures using the Common Reflection Surface (CRS) Stack Method
This PhD thesis aims to evaluate whether the Common-Refl ection-Surface (CRS) stack method can be considered as a more cost efficient processing alternative to the conventionally used Common Midpoint (CMP) stack method for processing of shallow and ultrashallow reflection data. The CRS stack is a …
