Snow is a fascinating material with a complex and evolving microstructure. Snow avalanches, notably slab avalanches, are generally initiated by failure and collapse in the snowpack of a so-called weak layer, whose thickness can be very small (a few mm). This phenomenon, in which the instability of a whole slope is ultimately controlled by rupture mechanisms at the scale of the microstructure of the weak layer, is intrinsically multiscale.

Key points of the PhD:

• Development of an innovative numerical approach
• Applications to natural hazards (snow avalanches)
• Stimulating and multidisciplinary work team

The project CURE (Coupled multiprocess research for reducing landfill emissions) investigates the reduction of the emission potential of landfills by in situ stabilisation measures and will develop predictive tools to forecast the pertaining processes and residual emissions. The objective of the research carried out in this particular PhD project is to quantitatively analyse the spatio-temporal response of landfills to different in-situ stabilisation measures by monitoring the change in quantity and quality of emissions through the water and gas phase as well as the change in the landfills’ structural architecture. This will be achieved by high-resolution measurements of

• Leachate quantity and quality, including stable isotopes and DNA/RNA profiling
• 3D temperature time series and 3D water content time series
• Gas quantity and quality
• Stabilisation-induced consolidation.

I would like to invite applications for a Severo Ochoa PostDoc Researcher Position at the CIMNE-UPC Geomechanics group  in Barcelona. It is an opportunity to join an active research group working in advanced coupled numerical analysis.  The appointment is intended to run for three years. The deadline for applications is June 14th.  More details are provided in the attached file.

Context:This PhD will take place within HoTMiX which is a joint French-German academic research project funded for 3 years by the ANR and DFG agencies. It brings together 6 academic labs and is supported by the St Gobain and Safran companies. The aim of the project is to provide a deep understanding of the relationships between the nonlinear mechanical response of oxide materials at very high temperature and their microstructure at the nanoscale. The relationship between microstructure and mechanical properties will be explored by combining two different approaches. In situ measurements at very high temperature or under applied stresses will be carried out using X-ray based advanced techniques at synchrotron radiation beamlines and accurate microstructural modelling based on virtual microstructures submitted to temperature and external stresses evolutions will be developed. More details on the HoTMiX project can be found here: www.bam.de/hotmix

Applications are welcomed for a joint PhD position between GeoRessources laboratory (University of Lorraine), LFCR laboratory (University of Pau) and IRSN. The objective of this thesis is to propose mesoscopic models capable of taking into account Hydromechanical and Electrokinetic couplings when simulating flow and transport in large representative elemental volumes (REVs) typically out of reach of molecular methods.

The candidate must be a highly motivated and autonomous person with a recent university master’s degree (or equivalent) in mechanics, reservoir engineering, applied mathematics, civil engineering or other relevant field. He or she must demonstrate a fundamental knowledge of the principles of fluid mechanics governing the behaviour of porous media. Experience in the development of numerical methods, in particular LBM methods would be an asset. The successful applicant will work under the supervision of

Dr Fabrice Golfier (GeoRessources) and Dr Amael Obliger (LFCR), as well as Dr Anne-Julie Tinet (GeoRessources) and Dr Magdalena Dymitrowska (IRSN).

Candidates are invited to submit their CV, master’s transcripts and cover letter here: https://bit.ly/2W2NFhI

The Geotechnics Research Group (GRG) in Department of Architecture and Civil Engineering (ACE) at Chalmers University of Technology, Sweden, is looking for PhD students and  Postdoctoral Researchers in Infrastructure Geotechnics (max. two positions each). The applicants are expected to be passionate about introducing/developing the state-of-the-art of modelling and testing of coupled processes (thermo-hydro-mechanical) into geotechnical engineering. The current research projects in infrastructure geotechnics include application of deep mixing under road and railway embankments and bottom support of excavations, as well as modelling natural and man-made slopes etc. These are problems, where the coupling of mechanical, hydraulic and thermal response, as well as soil-structure interaction, is important. The applicants are expected to engage with industry, to create innovative solutions for major stakeholders. In parallel with research,  the applicants are expected to contribute to teaching at undergraduate or Masters level (typically max. 10%-20% of their time), with focus on Geotechnical Engineering. The positions area temporary research positions (4-5 years for PhD, 2 years for Postdoc), fully funded by external research projects.
