Workshop Outline08.45 - 09.00 Welcome and Introduction, Outline of Expected Workshop Outcomes
Session 1 09.00 - 10.30 Present State of Practice and Challenges in Numerical Analysis of Natural and Man-Made Slopes (Approximate Duration: 90 mins.)
The first part of the workshop aims to provide an understanding of building a systematic approach towards constructing conceptual models for the idealization of slope stability assessments in soils and rock masses. Fundamental methods (limit equilibrium, finite elements, models based on block theory) for building numerical models for slope stability analysis will be introduced, along with their major assumptions and domains of validity.
The perspective is to be presented focusing on the current state of art in conventional design procedures, including the ones not necessarily being outlined by codes and regulations. Needs for advanced level of discussion such as implementation of physical and model-based uncertainties, characterization options, external loading conditions and varying state of pore pressure distributions will be addressed. An overview of the cutting-edge numerical modelling tools incorporating rigorous methods of reflecting discontinuity-controlled nature of rock masses on numerical models will be assessed. The discussions will be kept restricted to problems which can be characterized through limited deformation concepts.
The examples will be presented in an order of increasing complexity, coupled with discussions on case specific sensitivity of key input parameters. Discussed subtopics will be supported by 2D/3D numerical analyses, within an interactive framework augmented by participant feedback. Interpretation of results will be made with special attention to compatibility in reflecting the expected or experienced in-situ behaviour. Justification of conducting analyses in 3D wherever required, and possible will be made. Making the most out of observational method, thus field measurement-based model calibration attempts will be introduced.
The closure session is dedicated to allowing time and space for pronounced feedback from participants on the delivered content, with specific comments and/or questions on addressing the needs of current projects, evolving code requirements and challenges. This part is organized with an intend to generate a free speech platform among geo-professionals on slope stability assessment with the motivation of blending common engineering sense with smart utilization of advancing software tools, leading into rational and insightful decisions for community benefit.

Workshop Outline08.45 - 09.00 Welcome and Introduction, Outline of Expected Workshop Outcomes
Session 1 09.00 - 10.15 Multi-temporal multi-platform satellite DInSAR data for geotechnical applications (Approximate Duration: 75 mins.) - Prof. Dario Peduto
The first part of the Session is aimed at highlighting the potential of merging conventional (ground-based) and innovative (remote sensing) monitoring techniques in the field of geotechnical engineering and engineering geology applications. Special focus will be devoted to ground displacement monitoring from small to wide areas with data derived from the interferometric processing of Synthetic Aperture Radar (SAR) images. As for SAR, background information will be provided concerning sensors, Differential Interferometric image processing (DInSAR), precision/accuracy, procedures for their use at different scales, and their integration with ground-based techniques.
In the second part of the session, an overview of possible applications in the field of geotechnics/engineering geology will be provided through a case history dealing with different phenomena (i.e. slow-moving landslides, subsidence, active faults, post-seismic ground settlements) involving different types of structures/infrastructure (i.e. buildings, roads, embankments, bridges).
10.15 - 10.30 Break (15 mins.)Session 2 10.30 - 12.30 The use of satellite DInSAR data for landslide characterization and consequence analysis to the built environment (Approximate Duration: 120 minutes) - Dr. Gianfranco Nicodemo
The first part of this session will be devoted to a tutorial for the selection of the optimal SAR sensor and image dataset for a target area. Practical examples of data acquisition through web portals will clarify current data accessibility. Procedures for the upload, analysis, post-processing, and interpretation of the DInSAR-derived displacement map will be presented and implemented.
The second part will consist of a tutorial focusing on the use of DInSAR data for slow-moving landslide mapping and characterization at different scales highlighting specific limits and potential.
The third part will involve the participants in the practical use of multi-source data (DInSAR data and damage survey results) to derive cause (i.e. ground displacements) - effect (i.e. damage) relationships for buildings in slow-moving landslide-affected areas, also showing their exploitation for landslide vulnerability and risk assessment.
12.30 - 12.45 Break (15 mins.)Session 3 12.45 - 13.00 Closure Remarks (Approximate Duration: 15 minutes) - Prof. Dario Peduto and Dr. Gianfranco Nicodemo
