Course contents :

| Applied Geophysics aims to investigate the underground, whether within the Earth or under an engineering site using principles of physics. The physics of methods range from seismic waves propagation to the study of the Earth's gravitational field.
Geophysical exploration rely a vast range of subjects including physics, geology, mathematics, modern means of measurements and computations. Besides mastering these technical capabilities, it is essential for an engineer to learn to diagnose problems given a geological context in order to design appropriate solutions and to add to the knowledge a practice field intuition. That is why field work will be done by students, and examples in connection with the various fields of application (environment, hydrogeology, oil exploration and mining, public works, geotechnical exploration in marine, ...) will be analyzed during the course.
The course covers the main modern geophysical methods (seismic, electrical, electromagnetic, gravity, magnetic) and introduce several specific methods (surface waves, nuclear magnetic resonance). For each method, the course discusses the advantages and limitations, petrophysics, physical basis, field implementation, data processing and interpretation. |
|
Learning outcomes of the course :
|
| * Understand how and why geophysics allow a non-destructive recognition the underground.
* Understand the underlying basics of mathematics and physics behind geophysical methods and their interpretation.
* Be able to analyze the possibilities and limitations of various methods.
* Be able to design a survey on the basis of the geoscientific context (geological, hydrogeological, mining, tectonics, etc. ...).
* Know how to interpret geophysical results and how to integrate them among other data. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| A basic training in physics, mathematics and earth sciences is desired. |
|
Planned learning activities and teaching methods :
|
| The lab work consists of three parts:
The analysis of real world examples in which the geophysical results are acquired and processed;
The use of software for the processing and modeling of geophysical data to obtain the geophysical results;
Field work devoted to the implementation of certain methods, processing and interpretation of data collected. |

|
Recommended or required readings :
|
| Slides available on WEBCT. |
|
Assessment methods and criteria :
|
| The final note is obtained through a geometrical weighted average between:
