This doctoral research in the field of geosciences explores the use of remote sensing techniques such as aerial photogrammetry, infrared thermography, and satellite interferometry (InSAR) for the study and management of landslide-associated risks, through a multi-methodological approach. The adoption of a holistic analytical framework allows for leveraging the strengths of each survey technique, compensating for their relative limitations, and providing a detailed and multi-scale view of landslide phenomena. The research is structured around two main case studies: the first case examines the synergistic application of digital and infrared aerial photogrammetry for assessing geomechanical parameters in intensely fractured rock masses; the second case focuses on the use of InSAR to monitor large-scale ground deformations, with particular attention to areas subject to slow gravitational movements. Both case studies demonstrate the effectiveness of remote sensing techniques in providing valuable insights into slope movements and associated deformations, highlighting the importance of an integrated approach for effective land management. This research aims to enrich the field of applied geology, proposing innovative methodologies to address the challenges associated with the prevention of and response to geological risks, with significant implications for the safeguarding of communities and the conservation of the environment in risk-prone areas.
Questa ricerca dottorale nel campo delle geo-scienze esplora l’utilizzo di tecniche di telerilevamento quali, la fotogrammetria aerea, la termografia ad infrarossi e l’interferometria satellitare (InSAR), per lo studio e la gestione dei rischi associati alle frane, attraverso un approccio multi-metodologico. L'adozione di un quadro analitico olistico permette di sfruttare i punti di forza di ciascuna tecnica di rilievo, compensando le relative limitazioni e fornendo una visione dettagliata e multi-scalare dei fenomeni franosi. La ricerca si articola in due casi di studio principali: il primo caso esamina l'applicazione sinergica della fotogrammetria aerea digitale e infrarossa per la valutazione dei parametri geomeccanici in ammassi rocciosi intensamente fratturati; il secondo caso si concentra sull'utilizzo dell'InSAR per monitorare deformazioni del terreno su larga scala, con particolare attenzione alle aree soggette a movimenti gravitativi lenti. Entrambi i casi di studio dimostrano l'efficacia delle tecniche di telerilevamento nel fornire insight preziosi sui movimenti di versante e sulle deformazioni associate, evidenziando l'importanza di un approccio integrato per una gestione efficace del territorio. Questa ricerca si propone come un punto di arricchimento nel campo della geologia applicata, proponendo metodologie innovative per affrontare le sfide associate alla prevenzione e alla risposta ai rischi geologici, con implicazioni significative per la salvaguardia delle comunità e la conservazione dell'ambiente in aree a rischio.

Abstract
This doctoral research in the field of geosciences explores the use of remote sensing techniques such as aerial photogrammetry, infrared thermography, and satellite interferometry (InSAR) for the study and management of landslide-associated risks, through a multi-methodological approach. The adoption of a holistic analytical framework allows for leveraging the strengths of each survey technique, compensating for their relative limitations, and providing a detailed and multi-scale view of landslide phenomena. The research is structured around two main case studies: the first case examines the synergistic application of digital and infrared aerial photogrammetry for assessing geomechanical parameters in intensely fractured rock masses; the second case focuses on the use of InSAR to monitor large-scale ground deformations, with particular attention to areas subject to slow gravitational movements. Both case studies demonstrate the effectiveness of remote sensing techniques in providing valuable insights into slope movements and associated deformations, highlighting the importance of an integrated approach for effective land management. This research aims to enrich the field of applied geology, proposing innovative methodologies to address the challenges associated with the prevention of and response to geological risks, with significant implications for the safeguarding of communities and the conservation of the environment in risk-prone areas.File | Dimensione | Formato | |
