Morphological evidences and computer science techniques in order to evaluate tsunami inundation limit - Evidenze morfologiche, rilievo digitale ed applicazioni informatiche al fine della valutazione del limite di inondazione da tsunami

Terrestrial Laser Scanner surveys performed in coastal area have generated 3D cloud points used to obtain digital elevation model and standard deviation of the micro-topography of coastal surfaces. Starting from data collected, roughness. coefficients have been estimated for each surface typology characterizing the coastal area (sand calcarenite, vegetation, etc). Applying Machine Learning techniques on digital images, the extension and the surface typology of these areas have been obtained. All data collected have been elaborated by means of software implemented stalling from known hydrodynamic formula to evaluate the inland penetration of a hypothesized tsunami.
