Job description

Offer DescriptionHydrogeophysical signals obtained from electrical methods are related to coupled ion transport processes, or so-called off-diagonal processes, occurring at the pore scale but being probed at a much larger scale using field geophysical measurements. The classical way of interpreting such signals is based on inversion methods that relate the signal to one in situ parameter of interest. However, because of the complexity of natural systems, the inversion method does not ensure the uniqueness of the interpretation of the geophysical signal. A direct modeling approach that takes into account the full complexity of the system would then be very useful to provide a sensitivity analysis of the interpretations. In this PhD thesis project, the candidate will address this problem, using recent developments made at ISTO, BRGM (France), and LBNL (USA) to carry out direct modeling of electrical signals in hydrogeophysics using a reactive transport modeling approach.RequirementsResearch Field Geosciences » Hydrology Education Level Master Degree or equivalentResearch Field Environmental science » Earth science Education Level Master Degree or equivalentResearch Field Physics » Computational physics Education Level Master Degree or equivalentSkills/QualificationsWe welcome applicants with a Master’s degree in engineering or natural sciences (Earth sciences, chemistry or physics). Experience with numerical modeling is required. Good knowledge of fluid mechanics and transport processes, as well as some experience with the use of Matlab or Python, will be appreciated. It is expected that the doctoral fellow closely cooperates with the aforementioned supervisors and possibly others, so the ability for interdisciplinary work and good organizational skills are required. The doctoral fellow should also be fluent in English (oral and written).Languages ENGLISH Level GoodAdditional InformationWork Location(s)Number of offers available 1 Company/Institute University of Orléans Country France City Orléans Postal Code 45071 Street rue de le Férollerie GeofieldWhere to apply E-mailchristophe.tournassat@univ-orleans.frContact CityOrléans WebsiteStreetrue Claude Guillemin Postal Code45071 E-Mailp.leroy@brgm.frSTATUS: EXPIRED
