HYDROGEOLOGICAL RISK MITIGATION OF AN UNSTABLE SIDE

As part of the design of "hydrogeological risk mitigation interventions connected to the instability of the hilly slopes in Loc. Cortedomini and capital" in the municipal area of ​​Castel San Giorgio (SA), Geotec S.r.l. He performed drone, topographical, aerophotogrammetric, geomatic and geological and geophysical investigations to define any sub-work, as well as the geomechanical characteristics of the rocky clusters present in the studio area and the danger of landslides in rock and fall boulders to which the inhabited center is exhibited. The work phases consisted of a preliminary high -resolution aerofotogrammetric relief with SAPR aid (remotely piloted aircraft system) for the creation of three -dimensional models and the cartographic bases of representation; Processing, filtering and data processing collected by photogrammetry, in order to create a three -dimensional model of the area, for morphometric analyzes and the creation of planimetric and perspective cartographies; extrapolation of 3D detailed models of rocky fronts for gestructural and morphometric analyzes by means of semi -automatic calculation algorithms; Fall analysis of boulders through simulations on high resolution DTM; Data processing in the GIS field, realization of the thematic synthetic theme cartographies.
