  Information - NH3.02 Landslides and erosion monitoring and characterization using high resolution DEM, LIDAR and other DEM techniques

Event Information
The new techniques of acquisition of high resolution digital elevation model (DEM) open new field of researches in terrain analysis because of the increasing precision and availability of these documents. Now high resolution DEM (HRDEM) are easily acquired either by airborne or terrestrial LIDAR (Light Detection And Ranging). In particular, HRDEM permit new monitoring methods, geomorphic and morphometric analysis:
- The simple visual inspection of a shaded relief HRDEM permits to identify most of present and past instabilities.
- HRDEM time series for monitoring, coupled with DGPS (Differential Global Positioning System) or not, permits to analyze the entire slope movements and processes.
- HRDEM allows also detailed rock face structural analysis which is fundamental for the rock slope stability analysis.
- Erosion by debris-flow and river can be qualified using ground base LIDAR.
- HRDEM are used too for the detection of instable volumes at several scales and the estimation of their distributions.

The goal of this session is to share experiences related to new HRDEM analysis techniques and also to discover some new case studies. HRDEM analysis is a challenge for the future research in slope hazard assessment and erosion processes.
