toolsFor 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.


TRIGRS - A Fortran Program for Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Analysis, Version 2.1.

  • 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 Delineation
  • 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)





Statistical treatment of landslide sizes


    • Some GRASS GIS Python scripts for (i) generating a bedding attitude layer starting from a bedding trace layer and a DEM, and (ii) for interpolating bedding attitude data and obtaining a morpho-structural layer (cataclinal, anaclinal, orthoclinal slopes) - (by Ivan Marchesini)
    • We have contributed to the ICL Landslide Teaching Tools, edited by Kyoji Sassa, Bin He, Mauri McSaveney, Osamu Nagai, and published by ICL & UNESCO [ISBN: 978-4-9903382-2-0].




Geostat 2010 Materials


  • A GRASS GIS python code developed to alter a DEM according to the presence of a road network. The roads are dug into the DEM (typically having a resolution of 5 to 10 meters) - (by Ivan Marchesini)
