Geomatics in support of geotechnics in landslide forecasting, analysis and slope stabilization

Innovative researches developed by the Authors are described in order to demonstrate the usefulness of GIS (Geographic Information System) in support of geotechnical analysis, with particular reference to risk zoning and mitigation and to the monitoring of slopes. A multivariate statistical procedure for the estimation of landslide susceptibility, an automatic procedure providing maps of the countermeasures to recommend for slope stabilization and reinforcement, and a cognitive/predictive hydrological-geotechnical (IHG) model coupled with a dense, low-cost network of sensors are presented. The contribution of GIS environment to the analysis and prevention of landslide susceptibility, both at wide area and at local scale, as well as to the support in the choice of the suitable countermeasures is highlighted.
