APPLIED GEOPHYSICS

The course will be composed of two parts:
part 1: introduction to exploration geophysics, will introduce the general concepts of Geophysics applied with particular regard to:
• physical principles of the main electrical, elettomagnetic, seismic, magnetic and gravimetric methods
• concepts of resolution and penetration
• general definition of geophysical inversion
• basic concepts about data acquisition of the main methodologies

Part 2: exploration methods for environmental purposes. The methods that will be discussed are:
-traditional and tomographic geo-electrics, particularly with special regard to hydrological and hydrogeological applications
-spectral induced polarisation with applications to identify contaminants in the subsurface
-low frequency electromagnetic methods for contaminated site exploration and identification of structures in the first meters of the subsoil
- GPR and its potential applications to stratigraphy, engineering, hydrology, with a particular focus on processing and interpretation
-advanced high-resolution seismics for structural and stratigraphic definition of the top tens to hundreds of metres
-seismic refraction and surface waves seismic engineering and their geotechnical applications
-seismic, radar and geoelectrical cross-hole geophysical methods
- well logs and their environmental and hydrological applications.

For all methods special attention will be given to their applications, with examples from literature and from the experience of the lecturer. Demonstration will be given of the main methods methods, followed by processing, inversion and interpretation of laboratory data.
