Prerequisites
Good knowledge of geomaterials and soil mechanics as taught in courses LGCIV1031 and LGCIV1072
Main themes
The objective of this course is to learn how to manage the different scientific and technical aspects related to geoenvironmental and geoenergy hydrogeology, with links to geomechanics. It contributes to the management of environmental risk, which is an integral part of the geotechnical engineer's job, but also to current challenges related to new sources of energy and storage underground (geothermal, hydrogen, …), and the waste disposals (nuclear, CO2,…).
The course has two parts:
  • The first part deals with theoretical concepts: Fundamental principles of fluid flow and heat transport in porous media, behavior of unsaturated soils and rocks, poromechanics.
  • The second part deals with applications: geothermal energy, aquifer thermal energy storage, underground compressed air storage, industrial soil pollution, Nuclear and CO2 underground storage, unconventional oil and gas extraction.
Learning outcomes

At the end of this learning unit, the student is able to :

1 Regarding the AA reference system of the 'Master of Civil Engineering Construction" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes: AA1.1, AA1.2, AA1.3, AA2 .1, AA2.2, AA5.1, AA5.3, AA5.5, AA6.2, AA6.3, AA6.4.
At the end of this course, the student must be able to:
  • Understand transport and balance between the different soil phases (solid, liquid, gas)
  • Characterize advection, diffusion, dispersion and attenuation processes in saturated soil and unsaturated soil, through laboratory and in situ tests
  • Evaluate the mobility of non-aqueous fluids (light and heavy) in a given geoenvironmental context  
  • Determine hydrogeological parameters (transmissivity, storage, etc.) using in situ tests and transient pumping tests
  • Calculate flow velocities and drawdown induced by pumping under transient conditions
  • Pre-design a geothermal or hydrothermal installation
  • Know the challenges and technologies currenty developed for underground storage (Nuclear waste disposal, CO2, Hydrogen).
