| Course contents : | For the duration of this course, virtual geophysical companies will be created by teams of several students. Several case studies focusing on "engineering" or "research" aspects will be offered to students. These case studies will be distributed to the different teams who will design the project and carry out the study, from the bid offer price or the research project, which will be analyzed by an external expert, until the presentation of results. The proposed sites (urban or rural conditions, a study of polluted sites, hydrogeological study, environmental study civil engineering or geological study neotectonics, mining site) generally fit in an existing problem in connection with the real world.
This course requires a good knowledge of the different geophysical methods (seismic, electrical, electromagnetic, magnetic, gravimetric) and a good understanding of the inherent limitations of these (resolution, depth investigation, contrast) in order to identify how to reach the objectives of each study. The project includes not only geophysical aspects, but also aspects concerning the matter in hand (hydrogeology, geotechnical, tectonics, environmental, mining). It is important for the success of the project that students cooperate effectively within teams.
The aim is therefore to give an overview of teamwork in the real world and to give students a certain freedom of action to ensure a better autonomy in geophysics (set up, price, acquisition and analysis of a geophysical study at a hectometric scale). |
|
| Course objective : | The main objective of this course is put students in the role of an engineer's team which must conduct a geophysical study with specific goals. The overall objective can be broken down into several sub-objectives:
- The completion of specifications and a bid offer for the study or research project proposal;
- Teamwork;
- The design of a geophysical survey at a site;
- The collection of geophysical data;
- The processing and interpretation of geophysical data;
- The presentation of geophysical results;
- The integration of geophysical results with other geological data, geotechnical, hydrogeological...

| Prerequisites : | GEOL0001-1 Course of Geology and Engineering Geology or equivalent
GEOL0021-7 Geophysical Prospecting or equivalent |
|
| Workshops : | Interpretation of geophysical data in the classroom (software commonly used: Matlab, Res2dinv, sardin, reflexw, geopsy):
- Viewing and comparison of data;
- Data processing;
- Modeling and inversion;
- Presentation of results.
Implementation of geophysical methods on site
- Direct current methods (profiles, surveys, tomography, spontaneous potential);
- induced polarization in the time domain (trailed, surveys, tomography);
- Seismics (P and S, refraction, reflection, surface waves);
- Ambient seismic noise (H / V);
- Micro-gravimetry;
- (Subject to availability: radar, magnetism and electromagnetism induced).

|
| Organization : | The course is organized during the first quarter as follows *:
Weeks 1 and 2:
- The various projects will be exposed, groups formed and projects assigned;
- selection of secretaries and leaders of brainstorming meetings **;
- The reference documents will be presented (books, newspapers, websites, previous projects);
- meetings brainstorming 1 and 2 logistics and methods choice;
- site visit between week 1 and 2 (mandatory);
- first draft of specifications at the end of the week 2.
Weeks 3 and 4: Weeks 5 and 6
- Meeting "brainstorming 3" on the processing and data analysis of the day test (minutes delivered at the end of the week 6).
Week 7
- Final version of the specification and the bid offer.
Week 8 to 12
- Acquisition of geophysical data. For each day of acquisition, a brief overview of acquisition settings and data must be provided ***.
Week 13 to 14
- Interpretation of data and writing the final report, oral presentation.
* The schedule may be tailored to the needs of students and availability of equipment.
** All meetings "brainstorming" (brainstorming session on a theme chosen) will have to be minutes in which presences, decisions and actions will be noted. These PVs should be handed Professor for the day after the meeting. These PVs are listed as the final report or oral presentation.
*** Not rated but mandatory, you can check the quality of data. |
|
| Written notes : | The previous projects are available, and some other real world projects as well. In addition, several reference books will be available to students. |
|
| Assessment : | The course evaluation will be based on a weighted average of minutes, the specifications and price offer or the research project, the final report and oral presentation of results.
Minutes (1 to 6 weeks): 1 individual grade for each secretary and convener
Specifications and price offer / research project (week 7): 1 team grade
Final Report (14 weeks): 1 team grade
Oral presentation (examination): 1 individual grade
The review is a presentation of project results. Each team presents the results together. Following the presentation, questions are raised individually to each member of the team.
The jury will be composed of teachers and engineers. |
