1st Int. Workshop RootS23 – “SOIL-PLANT-ATMOSPHERE INTERACTION: MECHANISMS, PROCESSES AND GEOTECHNICAL ENGINEERING IMPLICATIONS” – University of Perugia, Perugia (Italy) – 20th-21st April 2023

Dear Colleagues, 

we are delighted to inform you about the 1st International Workshop RootS23 – “SOIL-PLANT-ATMOSPHERE INTERACTION: MECHANISMS, PROCESSES AND GEOTECHNICAL ENGINEERING IMPLICATIONS”, which will be held on April 20th and 21st in Perugia, Italy

The 1st Int. Workshop RootS23 will focus on the current state of knowledge and research concerning the topic of soil-vegetation-atmosphere interaction. This is a very broad and multidisciplinary research theme, spanning several scientific fields, each contributing to the investigation and modeling of specific aspects of the soil and plant behavior, upon variable climatic conditions. The Workshop is mainly addressed to researchers in geotechnical engineering, but the participation of researchers working in other fields (e.g., foresters, agronomists, soil physicians, ecologists, ….) is very welcome and considered fruitful for a constructive contamination of knowledge. 

Twenty invited Speakers will present their research on two main aspects: 

– the mechanisms through which vegetation favours ground mechanical reinforcement;  

– the phenomena and processes underlying soil-plant-atmosphere interaction, which typically require thermo-hydro-mechanical (THM) coupled analyses

and in more detail on: plant’s physical and hydrological properties; root architecture and properties; experimental evidence of the effects of vegetation evolution on soil hydrological and mechanical conditions; THM numerical analysis of the soil-vegetation-atmosphere interaction; ground bio-engineering techniques for shallow slope stability.  

Two ‘open discussions’ will be specifically dedicated to researchers who shall contribute from the floor with very short presentations (3-4 minutes) dealing with in-progress research, aiming at a fruitful and inspiring cross-contamination. 

You may find attached the programme and the flyer of the workshop. 

We hope that the workshop will represent an opportunity to share ideas and encourage new research collaborations, thus improving the strength of the academic network. 

If any of you may find this workshop interesting, we will be happy to give further information about the location and the venue. 

In this case, please contact Manuela Cecconi ( and Vito Tagarelli ( 

We sincerely look forward to seeing you in Perugia next April. 

On the behalf of the organizing committee  (Manuela Cecconi, Federica Cotecchia, Vincenzo Pane, Vito Tagarelli)

International conference dedicated to the memory of Prof. Pierre Bérest

An international conference on “Underground Storage and Geoenergies” will be held in Ecole Polytechnique (Palaiseau close to Paris) on 14-15 June 2023. This conference is dedicated to the memory of Prof. Pierre Bérest and will follow a summer school on the same topic on 12-13 June. 

The scope covers salt cavern storage, C02 sequestration, nuclear waste disposal and geothermal energy.

There is no registration fees (but registration is mandatory). The organization covers lunches and coffee breaks.

IRN GeoMech workshop series on “hydromechanical instabilities”, Aix-en-Provence, May 2-3 2023

Dear colleagues,

In the framework of the IRN GeoMech and the INRAE department AQUA, we organise a workshop on “hydromechanical instabilities” in Aix-en-Provence the 2nd and 3rd of May 2023.

The main objective of this workshop is to review recent advances in the understanding of the elementary mechanisms of destabilization of granular materials and their impact on failure modes (e.g. liquefaction, strain localization).

The topics addressed during the workshop may be related, for instance, to the mechanical response and stability of geomaterials in the presence of capillary or solid bridges (sintering, bio-calcification, dissolution/precipitation, …), internal erosion (suffusion and clogging), surface erosion, etc.

You will find more information on the workshop and all practical details on the following page:

Please note that the workshop is as usual free of charge which includes meals and accommodation (see details on the web page).

For people presenting, we ask you to send an extended abstract (2-4 pages) ahead of the workshop so that we can publish a booklet.

Here is the registration link (before March 31st) :

We are looking forward to see you in Aix-en-Provence next spring and enjoy thriving scientific discussions in an outstanding natural setting at the foot of the “montagne Sainte-Victoire”.

Best regards

The local organizing committee: Antoine Wautier, Nadia Benahmed, Pierre Philippe (INRAE, UMR RECOVER)
