Abstract

Using a 2m DTM we realized a high level topographical and morphological characterization of a mountain basin. The method compares different approaches for hydrologic terrain analysis to estimate the potential dynamic phenomena areas. The analysis focuses on the terrain preprocessing using ArcHydro. Furthermore, we tested the use of terrestrial laser scanner and drone survey to create dynamic 3D simulation of rapid mass movement concerning natural hazard phenomena. GIS is a helpful instrument for the public administration to evaluate the analysis results.
