EDITORIAL
Dear ALERT members,
it’s a great pleasure for me to open a new“ALERT” year, rich of
scientific and didacticevents, always aimed at sharing the
knowl-edge in Geomechanical fields. ALERT, overthe years, becomes
more and more a meet-ing platform for scientists, researchers
andstudents, as it is demonstrated by the largeparticipation to our
meetings, and by the nu-merous people that daily visit our
website(http://alertgeomaterials.eu/) in all its spe-cific
sections.
Three Workshop sessions and a DoctoralSchool (held as usual in
Aussois, France), to-gether with the ALERT summer school -
OlekZienkiewicz Course (this year organized inAssisi, Italy) have
been organized. All theprograms are very stimulating, and I
thankall the organizers for their hard (and silent!)work. Detailed
presentations of these eventsare provided hereafter.
The year 2017 represents a very importantpassage for our
association, and I truly haveconfidence that all our members will
assuretheir contribution. Following our Statute, inOctober, during
the Aussois meeting, the elec-tion of the new ALERT Board of
Directors willtake place, together with the choice of thenew
President and the formation of the newALERT Bureau. Board of
Directors, President
and Bureau, in front of the General Assem-bly, will share the
responsibility of managingour association for the next three years
(2017-2020). One section of the present issue of theNewsletter is
specifically devoted to this im-portant point, but I warmly ask
right now toeach responsible of each ALERT institution topromote
the internal debate among the mem-bers. This is the only way to get
new manag-ing organisms that can be representative ofall the
different souls of our association: noone is excluded!
I would thank all the members of the presentBoard of Directors
(2014-2017), for havingalways guaranteed a high scientific level
toall our activities. Finally, I would also per-sonally thank the
colleagues of the Bureau,Prof. Manuel Pastor, Prof. Ivo Herle with
MaxWiebicke and Prof. Stéphane Grange, for theireffortless and
always proactive contributionto the management of the current (and
some-time very boring!) administrative duties theassociation.
Once again, I close this Editorial by invitingall of you to
enrich this newsletter: all contri-butions for the next issues are
welcome!
Happy new “ALERT” year to all of you!!

ALERT Workshop 2016
In 2016 the annual ALERT Workshop was heldfrom Monday, 3rd until
Wednesday, 5th Oc-tober again in Aussois, France. The
regionaldistribution of the participants from the insti-tutional
members of ALERT Geomaterials isshown on the left hand side. In
total, 153 par-ticipants registered for the ALERT workshop2016.
As it was introduced in 2013, the session onTuesday lasted only
half a day allowing theBoard of Directors meeting, the PhD-prize
cer-emony and the Special lecture to be held inthe afternoon.
The three topics of the ALERT Workshop 2016are listed below:

Alessandro Tengattini(University of Sydney, Université
Grenoble-Alpes)
ALERT PhD Prize 2016
The jury of the ALERT PhD Prize 2016 wascomposed of the
professors Manuel Pastor(Universidad Politécnica de Madrid),
TakashiMatsushima (University of Tsukuba), GaryCouples (Heriot-Watt
University) and MichaelHicks (Delft University of Technology).
OnlyPhD students from one of the institutions be-longing to ALERT
are eligible candidates forthe prize which is dated to 1000
Euro.
The three finalists Alessandro Tengattini (Uni-versité
Grenoble-Alpes and University of Syd-ney), Alessandro Leonardi
(Swiss Federal In-stitute of Technology, Zurich) and Benoît
Par-doen (Université de Liège) were chosen bythe jury out of 9
applications.
The jury awarded the PhD student AlessandroTengattini for his
work entitled
A micro-mechanical study ofcemented granular materials
With his thesis Dr. Tengattini contributed tothe development of
a methodological frame-
work for cemented granular materials. Thisis accomplished by
relating the behaviour ofindividual grains to their collective
responseobserved at engineering scale by developing acombination of
analytical, experimental andnumerical approaches.
The acknowledgement of grain-scale be-haviour within this
methodological frame-work allows for a realistic validation of
theconstitutive models not only at the scale ofthe specimen
response and its localisation fea-tures, but also at the scale of
individual grains.This is pivotal in a number of open engineer-ing
problems where the localised evolutionof the micro-structure
dictates the observedresponse (e.g. the compartmentalisation
ofhydrocarbon reservoirs due to localised per-meability
reduction).
The abstract of the PhD thesis of Dr. Alessan-dro Tengattini is
available on the ALERT web-site.

ALERT Doctoral School 2016
The ALERT Doctoral School 2016 lasted fromThursday, 6th October
to Saturday, 8th Octo-ber and was attended by 96 participants.
Theschool was dedicated to
Modelling of instabilities andbifurcation in Geomechanics
The organization was carried out by JeanSulem, Ioannis Stefanou
(both from École desPonts ParisTech, France), Euripides Papami-chos
(Aristotle University of Thessaloniki,Greece) and Manolis Veveakis
(University ofNew South Wales, Australia). The accompany-ing book,
containing articles referring to thelectures, can be downloaded
from the ALERTwebsite.
The lectures were presented by
• Jean Sulem (École des Ponts ParisTech)• Tomasz Hueckel (Duke
University, USA)• Ioannis Stefanou (École des Ponts Paris-
Tech)• Pierre Bésuelle (Laboratoire 3SR)• Antonis Zervos
(University of Southamp-
ton)• Panos Papanastasiou (University of
Cyprus)• Euripides Papamichos (Aristotle University
of Thessaloniki)• Manolis Veveakis (University of New
South Wales)• Frédéric Collin (Université de Liège)• Thomas
Poulet (University of New South
Wales)
In order to tackle this topic, the school wasdivided into two
main parts:
• lectures that explained the theoreticalbackground to
experimental evidence andfinally the numerical modelling of
suchproblems
• an extensive practical session on Satur-day. The organisers
supplied a virtual boxwith all the software already installed tothe
participants and thus, lead smoothlythrough different numerical
aspects of bi-furcation analysis.
On behalf all the ALERT members we wantto thank the lecturers
and the organizers fortheir commitment.

ALERT Olek Zienkiewicz Course 2016
The 8th ALERT Olek Zienkiewicz Course washeld for five days in
September 2016 at theUniversity of Salerno, Italy.
Within the framework of an institutionalagreement, the 8th ALERT
OZ Course washeld jointly with the first week of the LARAMSchool
(International School on LAndslideRisk Assessment and Mitigation)
and it wasorganized by L. Cascini (University of Salerno,Italy) and
C. di Prisco (Politecnico di Milano,Italy).
The topic of the Course was
Geomechanics of Landslides
which represents a traditional yet challeng-ing field of
investigation discussed in threeRankine Lectures: 4th Rankine
Lecture “Long-term stability of clay slopes”, (A.W. Skempton,1964),
39th Rankine Lecture “Natural slopesand cuts: mevement and failure
mechanisms”,(S. Leroueil, 1999), and 57th Rankine Lec-ture
“Triggering and Motion of Landslides” (E.Alonso, 2017).
The objectives of the course were to pro-vide PhD students and
researchers with anoverview of the current knowledge in ge-
omechanics of materials involved in land-slides as well as
insights into modelling andgeomechanics-based susceptibility
analysis oflandslides.
Lectures and tutorials covered several issues:
• Soil characterization for landslide analysis• Constitutive
modeling for rainfall-induced
and earthquake-induced landslides• Diagnosis of landslide
processing in clayey
soils• Modeling of rock slides, rock falls and
landslides in coarse-grained soils• Landslide susceptibility
deterministic (and
statistical) analysis
Lectures and tutorials were delivered by: E.Alonso, M. Calvello,
L. Cascini, F. Cotecchia,S. Cuomo, C. di Prisco, S. Ferlisi, F.
Nadim, M.Pastor, C. Scavia.
The 8th ALERT Olek Zienkiewicz Course wasattended by 54 PhD
students and 2 YoungDoctors from 21 Countries (including the
stu-dents of the LARAM School). Besides the lec-tures, the ALERT
students had the opportunityto share scientific and technical
knowledgewith the colleagues of the LARAM School.

ALERT Olek Zienkiewicz Course 2017
The 10th edition of the ALERT OlekZienkiewicz Course will be
held from Monday,26th June to Friday, 30th June 2017 in
Assisi,Italy. The topic of the school is
Geotechnics of soft and organic soils
The school is organised by Cristina Jommi(Delft University of
Technology, the Nether-lands) and Claudio Tamagnini (University
ofPerugia, Italy).
Abstract: All over the world, habitable spacein deltas and river
areas is under increasingpressure from economic expansion,
growingpopulation, subsidence and the impact of cli-mate change. In
such environments, the typ-ical geological profile consists of soft
to verysoft soils, including soft clays, organic claysand peats,
which are particularly challengingboth from the theoretical and the
engineer-ing viewpoint. High compressibility togetherwith
relatively high shear strength, anisotropy,time-dependent
behaviour, biodegradation ofthe organic matter are some of the key
is-
sues which typically characterise these soils.Geotechnical
engineering in these contexts isextremely challenging and requires
advancedmaterial behaviour models and analysis tools,to reduce the
risk for damage and casualtiesand improve design and assessment
method-ologies. The main goal of the course is toprovide PhD
students and researchers witha comprehensive overview on soft soils
me-chanics and engineering, as well as an insightinto current
issues and advanced topics. Bothfundamental and applied topics are
tackled,during 4.5 days organised with lectures andpractical
sessions.
Lectures covering the following topics as wellas practical
sessions on some of them will bedelivered:
• Fundamental Behaviour• Constitutive Modelling• Modelling and
Numerical Implementation• Engineering of Soft Soils

The ALERT Special Lecturer 2017Prof. William G. Gray
Special Lecture 2017: Prof. William G. Gray
The Special lecture during the coming ALERTWorkshop 2017 will be
presented by Prof.William G. Gray from University of North
Car-olina, Chapel Hill and University of Vermont,Burlington. He
will talk about
Systematic Description of MultiphaseFlow in Porous Media
The mathematical description of the behav-ior of the fluid and
solid phases in porousmedia systems has evolved over the last
150years primarily in concert with, and as lim-ited by,
experimental capabilities to measurephysical system features. More
recent theo-retical approaches have advocated derivationof
governing equations based on conservationand thermodynamic
relations and rigorousmathematical tools. The resulting govern-ing
equations confirm that standard modelsare significant
simplifications of more gen-eral equations. A more complete and
con-sistent set of model equations includes de-pendence on
parameters and quantities thatare inaccessible using older
experimental ap-proaches. The extended theories, which in-clude
quantities such as interfacial areas per
volume and which recognize the formationof disconnected phases,
make demands onexperimentalists to develop methods for ac-cessing
time-dependent deformation and dis-tribution of phases in a system.
The neededexpertise is not to mine data in an effort tocome up with
correlations that describe thesystem behavior but to use the data
to deter-mine coefficient and function values in de-rived
equations. Concurrently, access to ad-vanced supercomputers
provides the ability tosimulate multiphase flows within porous
sys-tems at an intrapore scale. Knowledge gainedfrom highly
resolved studies sets the stage forsupporting larger scale models
of real systems.The recognition of the importance of
phasedistributions within a system provides a chal-lenge both in
simulating these distributions ata manageable scale and in
parameterizing themodels of the transient distributions. Here,we
will highlight some of the challenges andopportunities for
advancing physically-based,systematic theoretical descriptions of
multi-phase flow in porous media for practical us-age.
