Abstract

The project is aimed at tuning a multi-step, multi-scale and multi-disciplinary comprehensive analysis of Deep-seated gravitational slope deformation (DSGSD) processes, to better address their peculiarities in terms of both spatial and temporal scale in a hazard-oriented perspective. After a first phase of inventorying over large areas representative of the Apennine chain, especially where DSGSDs have been poorly studied, the application of techniques for landslides susceptibility assessment, properly adapted to the specificity of slope-scale processes, will allow for a better understanding of the physical process in relation to the conditioning factors, such as geological-structural and geomorphological properties. Satellite-based InSAR analyses will be applied for supporting the detection and assessing the state of activity, while catchment-scale geomorphometric analyses will be performed to assess the potential of geomorphic markers as proxies for DSGSD detection. Moving to the evaluation of risk associated to DSGSDs, especially in terms of potential to evolve as catastrophic failures, the project will focus on the detailed study of selected case histories to tune and refine a multi-modeling approach aimed at: i) framing the present stress-strain conditions in the long-term morpho-evolution that influences the process and ii) providing hints on the rock mass damage in terms of visco-plasticity properties of deforming slopes. Landscape evolution modeling will provide constraints to back-analyze in space and time the processes; multi-physics monitoring and modeling of an already equipped "site lab" will provide criteria for the visco-plastic parametrization of the slopes. The results will be integrated in a calibrated numerical model aimed at properly understanding the deformation rates inferred by satellite InSAR data in light of the creep behavior governing the process, thus providing useful hints for an efficient failure forecasting.
