Doctorat : modélisation basée sur les connaissances expertes pour évaluer la performance d'un recouvrement en restauration minière

The performance of soil barrier cover systems used to confine mine wastes relies on their ability to control the water balance. Yet, plants that establish with time on these covers impact their water balance and possibly their performance. Differing models are used to apprehend the hydrogeological behaviour of cover systems and evaluate their peformance (for example: UNSAT-H, SEEP/W, HYDRUS et LEACHM). Such models can include vegetation parameters as boundary condition but models are rarely calibrated and validated including vegetation effects.

This research project aims at calibrating and validating hydrogeological models for several types of vegetated covers by using in situ field data that were collected at the short-medium term, then to evaluate the long-term performance of cover system with a mature vegetation.

Field data are already available for the project and can be completed by in situ additionnal measurements when necessary.

Contrat doctoral

Bourse de recherche non-imposable allant de 23 000 à 26 000 $ CAD/année. Financement des frais de recherche et de la bourse déjà obtenus.

The RIME encompasses a major research program aimed at developing environmentally friendly, original, and practical solutions for the entire life cycle of a mine. Much of this work is accomplished while also training highly qualified personnel who represent the workforce of tomorrow.

Located at the Université du Québec en Abitibi-Témiscamingue, Quebec, Canada, the RIME expertise is recognized in Canada and internationnally. Nested in a mining region, the research is performed at the real scale on active and inactive mine sites, in collaboration with the managers of mine sites, to develop applied solutions.

The 16 professors work as a multidisciplinary team in collaboration with a hundred or so master and PhD students, as well as twenty or so research technicians and professionals.
