The Politecnico di Torino research unit focuses on GBInSAR data evaluation and interpretation (WP1) and on developing realistic landslide-evolution scenarios through numerical modelling (WP5).

Monitoring and modelling activities concern three reference sites: Torgiovannetto di Assisi in the Province of Perugia, the pilot area; Stromboli in the Province of Messina; and Beauregard in the Aosta Valley, both experimental sites.

Ground-based radar interferometry is validated through comparison with conventional monitoring data. Interferometric acquisition and interpretation support three-dimensional slope surveys for numerical-model geometry and provide spatially distributed displacement measurements for model validation and back-analysis.

The IBIS-L apparatus, acquired by RU3 in 2008, measures displacement across areas illuminated by electromagnetic waves emitted at regular intervals. Within the project, it is used to monitor the three reference landslides.

Interferometric campaign data are processed with dedicated software, with particular emphasis on innovative techniques for reducing atmospheric errors in ground-based radar measurements.

Corner reflectors and atmospheric stations installed on the slopes provide reference points and records of air pressure, humidity and temperature. These parameters are compared with radar and conventional measurements to optimise atmospheric-error evaluation and removal.

In-situ monitoring provides the basis for numerical modelling aimed at reproducing plausible large-rock-landslide evolution. Research addresses both model initialisation—geometry and mesh generation—and interpretation for scenario development.

Continuum approaches such as FEM and FDM, discontinuum approaches such as DEM, particle-based techniques and combined Finite-Discrete Element Methods (FDEM) are employed. Automatic tools support the efficient creation of three-dimensional models using commercial and open-source software.

Monitoring and numerical results are compared at significant georeferenced slope locations using GIS applications. Validated models are used to produce run-out scenarios, estimate critical levels and define threshold values that support pre-operational alerting procedures in collaboration with RU1 and in accordance with national regulations.
