In a groundbreaking study published in the ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, researchers have unveiled critical insights into how extreme rainfall events, such as the 2018 Vaia Storm, can induce significant ground deformations in vulnerable regions like Cortina d’Ampezzo, Italy. This area, renowned for its tourism and sporting activities, has been under scrutiny due to its susceptibility to landslides, making the findings particularly relevant for the construction sector.
Lead author R. Eskandari from the Politecnico di Milano emphasizes the importance of understanding these deformations, stating, “Our analysis provides a comprehensive view of how extreme weather conditions can dramatically alter ground stability, which is crucial for planning and construction in at-risk areas.” The research utilized advanced InSAR (Interferometric Synthetic Aperture Radar) data from the European Ground Motion Service (EGMS) to assess ground displacement before and after the storm, revealing that the extreme rainfall led to a notable acceleration of displacements, particularly in the horizontal East-West direction.
The implications of this research extend beyond academic interest; they pose significant commercial impacts for the construction industry. As construction projects increasingly occur in regions prone to extreme weather, understanding ground deformation patterns can inform risk assessments and project planning. With the potential for enhanced predictive models, construction firms can better anticipate and mitigate risks associated with landslides and ground instability, ultimately protecting their investments and ensuring safety.
Eskandari’s team found that areas with high pre-event displacement velocities experienced the most substantial changes post-storm. “This correlation indicates that regions already under stress are more likely to experience significant alterations in stability following extreme weather,” he adds. Such insights are invaluable for civil engineers and project managers who must navigate the complexities of building in environmentally sensitive areas.
As climate change continues to exacerbate weather extremes, the findings from this study could shape future developments in construction practices. By integrating real-time data and advanced monitoring techniques, the industry can evolve to prioritize safety and resilience, adapting to the increasing unpredictability of weather patterns.
