vEGU 2021 – call for abstracts – session NH8.4 on vegetation effects on slope stability and climate-induced geohazards
The NH8.4 session of the EGU General Assembly 2021 (vEGU, April 2021) is entitled ” Vegetation as nature-based solution for mitigating climate induced geo-hazards and associated consequences along slopes and streambanks” and is coordinated by Vittoria Capobianco (Norwegian Geotechnical Institute – NGI), Sabatino Cuomo (University of Salerno), Dominika Krzeminska (Norwegian Institute of Bioeconomy Research – NIBIO) and Anders Solheim (Norwegian Geotechnical Institute – NGI).
Contributions documenting, both through numerical or experimental studies, how vegetation can be beneficial in slope stability and plant-soil-atmosphere interaction in the unsaturated zone are welcome.
Specific topics and research questions related to this session are:
• How the plant-soil-atmosphere interaction affects the unsaturated zone and thus the slope stability?
• Measuring and quantifying the effects of vegetation as NBS for mitigating climate induced geo-hazards and associated consequences at or near instable slopes and along stream banks – case studies at full scale or laboratory scale
• How to ensure interdisciplinary interaction for sustainability and mutual synergies for studies containing vegetation as NBS for mitigating climate induced geo-hazards and associated consequences at or near instable slopes and along stream banks.
Further information about the session can be found here: https://meetingorganizer.copernicus.org/EGU21/session/38969
Interested participants are welcome to submit an abstract within 20 January 2021, which will be followed by an online presentation to be given during the virtual session.

Title: Micromechanics of cracking of clay subjected to air drying and/or gas breakthrough
Duration: 3 years
Start date: from 01/10/2020 to 31/12/2020
Eligibility: Applications from UK/EU applicants only, First Class Honours (or equivalent)
Where: Department of Civil and Environmental Engineering, University of Strathclyde, Glasgow, Scotland
Supervisors: Dr Matteo Pedrotti (https://www.strath.ac.uk/staff/pedrottimatteomr/) and Professor Alessandro Tarantino (https://www.strath.ac.uk/staff/tarantinoalessandroprof/)
This 3-year PhD at the University of Strathclyde will focus on investigating the mechanisms at the micro/particle scale underpinning the process of crack formation in clay associated with air drying and/or exposure of the clay interface to gas at high pressure.
The research will mainly be experimentally-based and the PhD candidate will make use of state of the art technologies for the investigation of the clay microstructure including X-Ray Computed Tomography, Environmental Scanning Microscopy, and Mercury Intrusion Porosimetry.
Despite 100 years of research on the macro-mechanical behaviour of clay, we are still largely ignoring underlying mechanisms at the particle scale. Clay micromechanics involves the understanding of the configuration of elements (particles) and the forces controlling the kinematics of such elements. Clay micromechanics (including the evolution of particle configuration in clays when subjected to mechanical loading) has rarely been investigated explicitly and is a young and rapidly growing discipline in the field of soil mechanics.
Besides joining a vibrant geotechnical community at Strathclyde, the candidate will join the International Research Centre For Clay Micromechanics (https://www.irccm.net ) which will provide the opportunity for international collaborations and to spend a period abroad in one of the partner universities (i.e. Chalmers University of Technology – Sweden, University of Twente – The Netherlands, Université Grenoble Alpes – France, University of Brasilia – Brazil, Politecnico di Bari – Italy, Technical University of Denmark – Denmark) .
Industrial contacts will be mainly focused, but not only, towards the Carbon Storage and Sequestration sector.
Two new experimentalist positions are available in the Geomechanics and Porous Media research group at Université de Pau et des Pays de l’Adour, Basque Coast Campus, Anglet, France:
Research Engineer Assistant in experimental porous media. Starting date: September 1st, 2020 (16 months). Details may be found at:

Vi segnaliamo, nell’ambito della EGU General Assembly 2020 (Vienna, 3-8 maggio 2020), la sessione sulla geotermia superficiale per il condizionamento degli edifici.
La sessione ERE 2.8, intitolata Shallow geothermal systems for building heating and cooling: geoscience and engineering approaches, è coordinata da Giorgia Dalla Santa (Università di Padova), Witold Bogusz (Polish Building Research Institute, Warsaw), Francesco Cecinato (Università di Milano), Fleur Loveridge (University of Leeds) e Donatella Sterpi (Politecnico di Milano). È possibile presentare entro il 15 gennaio 2020 un sommario a cui farà seguito una presentazione orale o tramite poster, da tenere nell’ambito della sessione durante il convegno.
The session welcomes contributions about shallow geothermal energy applications, including traditional closed- and open-loop borehole heat exchangers as well as so-called energy geostructures (e.g. thermo-active foundations, walls, tunnels).
Different types of analysis and approaches are relevant to this session, spanning from the evaluation of ground thermal properties to the mapping of shallow geothermal potential, from energy storage and district heating to sustainability issues and consequences of the geothermal energy use, from the design of new heat exchangers and installation techniques to the energy and thermo-(hydro-) mechanical performance of energy geostructures. Contributions based on experimental, analytical and numerical modelling are welcome as well as interventions about legislative aspects.

Opportunity for PhD studies on Unsaturated Geomaterials and Contaminant Transport at Monash University (Melbourne)
Three scholarships are available for PhD studies commencing in 2019. The scholarships will provide support for three years on a full-time basis for a research project leading to a PhD.
Project 1: the project aims at developing an experimentally validated theory of the behaviour of geosynthetic clay liners (GCLs) under high temperatures and salt gradients that will lead to a significant improvement in the understanding of their hydraulic behaviour. The PhD will focus on the evaluation of temperature effects, wet/dry cycles salt gradients and stress changes on the water retention curves (WRCs) of geosynthetic clay liners.
Project 2 (2 scholarships): the project will focus on contaminant transport through lining systems. Particular emphasis will be given to chemical compatibility issues between a suite of emerging contaminants (PFAS, etc.) and soil and geosynthetic liners. This project aims at providing practitioners with better tools to estimate the design life of hydraulic barriers systems.
Applicants should have an Honours 1 or First Class Honours Degree in Engineering or Science and an interest in analytical/numerical and experimental research. The scholarship value is A$28,500 per annum, with the possibility of a top-up depending on academic standing and/or experience. The potential for further earning is also possible through tutoring.
For further information, contact Prof. Malek Bouazza, at email@example.com. Applications including a curriculum vitae, a copy of academic transcript, evidence of English-language proficiency (international applicants only) names and contact details of at least two academic referees should be sent to the above email address.
Applications are invited for a one year full-time researcher based in the Department of Civil and Environmental Engineering at Imperial College London in the area of discrete element modelling and computational fluid dynamics. The successful applicant will join the Geotechnics research group as a member of research staff and will conduct research on an EPSRC funded project entitled “Particle-scale investigation of seepage induced geotechnical instability”. The work will be conducted under the supervision of Professor Catherine O’Sullivan.
The start date for this research post is July 1 2019.
