Post-doctoral position in geosciences M/F

id="offer-description" class="ecl-u-type-heading-2 ecl-u-mt-none ecl-u-mb-l">Offer Description At CNRS, ISTO, the main mission of the postdoctoral position is to model reactive transport in the unsaturated zone (UZ), on tentative representative scale of the Beauce aquifer. Thanks to the characterization of O-ZNS materials in the laboratory, petrophysical and hydrodynamic parameters determination over the entire unsaturated zone a hydrogeological model will be developed. The targeted model is to provide an in-depth understanding of the vadose structure and to identify the key physicochemical processes with their multilevel couplings and inter- dependencies across different scales and fluid phases. The O-ZNS observatory, located at an agricultural site in Villamblain (Centre Val de Loire, France), offers a unique observation/monitoring setup composed of an exceptional well having a depth of 20 m and a diameter of 4 m, along with a variety of boreholes and environmental sensors suitable for geochemical, microbiological, and hydrogeological investigations ( https://www.isto-orleans.fr/2022/03/17/installation-de-lobservatoire-o-… ). The observatory instrumentations allow the deployment of innovative sensors that can provide quantitative, massive, and highly resolved 3D measurements related to fluid flow and heat/mass transfer processes within the vadose zone (including reactive chemicals, redox processes/barriers, soil water content, electrochemical and electro-kinetic signals, et
