Lay summary
This proposal is related to the acquisition of a new terrestrial laser scanning (TLS) system used to analyze slope mass movements and erosion processes. TLS is a laser scanner that acquires several thousands of x, y, z points per second. It allows a detailed analysis of slope surfaces and rock walls. Over the last 2.5 years we have developed a research topic dedicated to the monitoring, structural and geomorphologic approach based on the TLS techniques. The success of our research and the improvement of the first generation TLS devices have convinced us to buy a new TLS, which will have an enhanced range for the data acquisition (up to 1500 m) and a better sensitivity to reflectivity. This new device will permit us continue to improve our tools and models related to slope destabilization. By studying more and more cases, we expect to improve the knowledge about mechanisms that lead to slope failure and control instabilities. In addition we will able to quickly react when a landslide moves, as we did for the Eiger collapse in 2006. It will also allow us to reinforce international and national research collaborations.
