Emergency stabilization of a landslide in Pirin National Park

A landslide in Pirin National Park, Bulgaria, was rapidly stabilized due to its critical threat to infrastructure. The landslide, occurring in December 2021 on a steep slope, measured 20 meters wide, 15 meters long, and up to 4 meters deep, primarily affecting a road embankment and endangering the nearby 'Syrchaliytsa' hydraulic canal. The study employed on-site inspections, geotechnical mapping, archival data analysis, and expert experience to assess terrain conditions and stability factors. A conceptual stabilization solution was developed based on these findings, leveraging local expertise in similar cases. This work highlights the importance of rapid intervention in high-risk areas, particularly within protected natural sites like Pirin National Park.
