Università
degli Studi di Milano Bicocca
The
Department is part of the new University of Milano-Bicocca. Its main research
subjects concern the assessment of risks: hydrogeological (landslides, floods,
groundwater contamination, etc.), seismic and volcanic, environmental on land
and at sea. The staff is composed of about 25 persons (professors, researchers
and technicians) with experience in different fields of geology and of risk
assessment. The staff developed extensive experience in the field study and
modelling of engineering geological problems, slope stability (rockfalls, debris
flows, deep seated gravitational deformations, liquefaction processes,
distribution and triggering thresholds, numerical simulation), sedimentological
aspects of fluvial transport and deposition, soil and rock properties
characterization (lab and in situ), marine geology and geotechnology,
geophysics. The Department is equipped with different technical laboratories for
mechanical testing on soil and rock, numerical simulations and data processing,
GIS analyses, aero-photogrammetric studies. Geophysical and hydrogeological
equipment is available for in situ testing.
The
Engineering Geological group has been partner and coordinator of national and
international research projects. Innovative research has been conducted to
develop a set of leading-hedge techniques for landslide modelling and hazard
assessment. More than 100 papers have been published on international journals
and proceedings of international conferences on these research topics.
The
department staff working on geological and hydrogeological risks has continuous
collaboration with other national and international universities and research
centers as well as with SMEs and university spin-off companies.
Contribution to CARiMan:
Geological
and hydrogeological processes are quite complex in nature and quite sensitive to
external constrains. End users, working on geological and hydrogeological risks,
are quite interested in the formulation of triggering thresholds for landlslides
or the transition from slow to very fast moving or catastrophic events. We want
to develop such thresholds for different geological and hydrogeological
phenomena (landslides of different types, groundwater contamination, etc.)
starting from in situ monitoring, with different techniques, and using both
expert knowledge as well as relatively simple algorithms. The results could be
developed in a user friendly system for end users to estimate level of risk in
different stages. This approach will be strongly supported by the use of GIS
tools as a consequence of the spatial distribution of the examined phenomena.
The
development of computer aided systems will be a major link with other partners
in the project with advanced experience in the development of such systems.
UNIMIB
could work as a Workpackage Manager (WP-Manager): development of new tools and
criteria for geological and hydrological risk management
The
workpackage will consist of the following main steps:
Data
acquisition for different phenomena with particular attention to monitoring
data. These will include, for example, landslide displacement, velocity,
acceleration, acoustic emissions, etc. surveyed both through ground-based and
satellite-based system. Our group will include a SME (TRE srl) working on
Synthetic Aperture Radar data collected through different satellites (ERS1 and
ERS2, RADARSAT, etc.). Groundwater contamination problems will be coped by
collecting data on the type of contaminant, its spatial and temporal
distribution through the adoption of hydrogeophysical methods. Various
contaminated sites will be examined with different techniques.
Definition
of thresholds for the triggering of different hazardous phenomena: transition
from slow to fast and very fast moving landslides; transition from limited
short-duration contaminations to fast-moving and long duration phenomena;
individuation of source areas for small fast moving landslides or for
groundwater or vadose zone contamination.
Definition
of algorithms, empirical, semi-empirical or physically-based, for the emission
of different alert phases to be linked with specific limiting risk actions by
the end.
Eventuial
development of such algorithms in computer aided risk management systems in
collaboration with other interested partners
Testing
and demonstration of the developed techniques on some specific cases of public
interest. Verification of the advantages of the application of these new
approaches in collaboration with end users involved directly in rosk management
at different levels.
Training
of researchers and technicians from public administrations to the use of such
tools
Short
description of the organisation
The
Department of the University of Milano-Bicocca has been founded on 1999. Its
main research subjects concern the assessment of geological and hydrogeological
risks. The staff is composed of 25 persons (professors, researchers and
technicians) with experience in different fields of geology and of risk
assessment in different geological fields and both in land and marine
environment. Soil mechanics, rock mechanics, marine geology, applied geophysics,
numerical modelling, GIS, and aerial photointerpretation
laboratories are available.
Different
original risk evaluation approaches have been developed at the department and
are currently under development or already in use by local and regional
technical administrations.
CV of the partners
Prof. Giovanni B. Crosta graduated in geology on 1987
at the University of Milano, PhD in Engineering Geology at the University of
Milano in collaboration with the United States Geological Survey (USGS) and the
University of Colorado, Boulder. Visiting scientist at the USGS Golden, Branch
of Risk Assessment. Research assistant at the University of Milano, between 1992
and 1997, associate professor at the University of Milano Bicocca since 1998.
Coordinator of the research unit of Milano Bicocca for different national and
international projetcs (Italian Space Agency, EC projects: INTERREG IIC,
DAMOCLES Project 5th framework) and
of research contracts for various private and public administrations and
companies. He developed some methods for landslide displacement analyses and the
modelling of different slope instability phenomena. Collaboration with national
and international universities and reserach centers.
