For our own research, we have designed and developed specific tools, mostly software. Here we provide information on software tools prepared or used by our team, or by scientists working with us. We try to keep the page updated with the latest releases of the SW. Should you need further information on the listed SW, or should you not be able to download or use the SW, you can write us.
This is a parallel implementation of TRIGRS, the Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Model for the timing and distribution of rainfall-induced shallow landslides. The saturated and unsaturated model with finite and infinite soil depth options are parallelized in the framework of the Message Passing Interface. In addition, the code contains new features and bug fixes, with respect to version 2.0.

Slope-units (SU) are a special type of terrain units bounded by drainage and divide lines that prove particularly well suited for landslide susceptibility modelling (LS) and associated terrain zonations.
We provide the new r.slopeunits software for the automatic delineation of SU.
The software, written mainly in the Python language for GRASS GIS 7.0, automates the process of delineating SU, given a DEM and a set of user-defined input parameters. (by Ivan Marchesini and Massimiliano Alvioli)

- TRIGR-S: A modified version of the Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Analysis (TRIGRS) code, version 2.0, originally prepared by the U.S. Geological Survey and available @ http://pubs.usgs.gov/of/2008/1159/. The new code (TRIGRS-S) uses a stochastic approach to compute, on a cell-by-cell basis, transient pore-pressure changes, and related changes in the factor of safety due to rainfall infiltration (by Salvatore Raia & Massimiliano Alvioli)
