Based on its scientific and technical expertise, Terranum carries out complete consulting works in the field of natural hazards, from regional detection to site-specific modelling, with:
Susceptibility mapping of gravitational hazards can be carried out by modelling potential source areas and runout, based on advanced geographic information system (GIS) processing and remote sensing data, such as aerial and mobile LiDAR, spaceborne RaDAR interferometry, aerial imaging. It aims at detecting, at a regional scale, sectors that can be potentially affected by slope instabilities, such as large slope deformations, shallow landslides, rockfalls, rock avalanches, debris flows and snow avalanches.
Hazard and stability assessments of single slope deformations can be carried out, based on detailed field mapping, destabilization and triggering factors assessment, landslide kinematic modelling, displacement monitoring (terrestrial LiDAR, Ground-Based InSAR, GNSS, extensometers, inclinometers, etc.), 2D and 3D runout modelling, and/or Safety Factor computations.
Terranum is carrying out complete and optimized landslide monitoring, from the design and acquisition to the final interpretation and recommendation. In addition to classic geotechnical tools such as inclinometers, extensometers or piezometers, Terranum is dealing with high-level monitoring systems in association with: CSG Srl and its multi-parametric geotechnical column DMS™, Ellegi Srl and its GB-InSAR device LiSALab™ and the University of Lausanne for LiDAR and GNSS facilities.
Hazard maps and quantitative risk assessments can be performed for all landslide types. Early Warning Systems (from field setup to data analysis and alarm sending) can be designed according to your needs.
