(Open to international experienced researchers)
Research Project: Development of numerical models for the characterization of natural hydro-systems, and treatment of vadose and capillary zones contaminated by light non-aqueous phase liquid
Research Field: Flow and transport in porous media
LE STUDIUM Loire Valley Institute for Advanced Studies is looking for an experienced scientist to join the the large research PIVOTS Programme (Environmental Technology Innovation, Development and Optimisation Platforms project) in the Centre-Val de Loire region, France.
The PIVOTS Programme is a coordinated set of seven experimental and analytical platforms focused on environmental quality monitoring and sustainable management of natural resources (soil, subsurface, surface water, groundwater, sediment, and air) within a context of global change.
Innovation in the area of the environment, ecotechnology, and eco-services is a major challenge for sustainable development in today’s societies. Innovations may arise from an integrated approach based research involving academic and industrial experts together at all stages of the value chain, from fundamental research to the validation of products and services. The goal of the PIVOTS Programme is to accomplish this integration and to promote the emergence of an economic stream in the area of environmental metrology, remediation processes, and associated services.
The successful candidate will be invited for a one-year fellowship to work on the PRIME and O-ZNS (https://plateformes-pivots.eu/?lang=en) Platforms for the Vadose Zone fluid flows and Remediation and Innovation for Environmental Metrology and will benefit from the dynamic scientific environment of the region. As a LE STUDIUM Loire Valley Institute for Advanced Studies Research Fellow, s/he will be part of an outward-looking and stimulating pluri-disciplinary scientific and international community.
SCIENTIFIC RESEARCH CONTEXT
Sustainable and effective remediation of contaminants from the subsurface is one of the biggest challenges in current environmental issues. This requires the use of innovative and effective treatment techniques to remediate polluted sites and to limit the risk of spreading the contaminations to groundwater. A research team at BRGM (the French Geological Survey) and ISTO (Earth Science Institute of Orléans) is working to study the fate and transport of organic pollutants for remediation perspective using natural observatories and multiscale pilots approach (see references below). One of the main current research projects of the teams is to study natural flows on the unsaturated zone and new techniques for the characterization and treatment of vadose zone contaminated by light non-aqueous phase liquids (LNAPLs).
The vadose zone (VZ) is known to play a major role within the critical zone as a controlling agent in the transmission of recharging water as well as contaminants from the land surface to groundwater. O-ZNS observatory provides an instrumented experimental site located in the heart of the Beauce region and a specialized laboratory situated at the ISTO.
The objective of the work to be conducted through the fellowship is to develop a numerical model that appropriately integrates (i) the heterogeneous vadose zone architecture, (ii) the multi-scale aspects (iii) the imbibition and drainage behavior of LNAPLs in a three-phase system; (iv) (v)the complex behavior of the foam flow in porous media particularly, non-Newtonian and compressibility effects. The developed model will be then validated against the experimental and observatory data of the PRIME and O-ZNS platforms.
MISSION OF THE RESEARCH SCIENTIST
The successful candidate will have the following missions:
- to strengthen the theoretical and modeling knowledge of the research team
- to develop the numerical models to study the multiphase flows (air-water, air-water-LNAPL) in porous media at laboratory and observatory scales
- to use the simulation outcomes to help design and validate new experimental setup and protocol for the projects and identify missing measurements
- to use the PRIME and O-ZNS platforms as a frame to conceptualize and validate the developed model against the experimental and observatory results
- to carry out internationally outstanding research for the above-mentioned project
- to disseminate this research through articles in journals of international standing, monographs and other appropriate forms of dissemination, including national and international conference presentations
- to support, comply with, and fully contribute to research plans and policies of the PRIME / O-ZNS teams.
We are looking for a senior researcher profile with experience in modeling flow and multiphase transport in porous media, NAPL fate and transport, complex fluid flow in porous media and experience in pore and Darcy scale numerical simulation including multiphase flow.
Record of publications in international peer-reviewed journals and proven ability to initiate projects in the research field will be taken into consideration.
THE FELLOWSHIP OFFER
The position is based in Orleans, France and offers 12 months of residency (two periods of 6-month residency can be considered) under a French labour contract of employment include:
