In May 2023, heavy rainfall across Central Europe triggered flooding alerts in Eastern Slovenia, raising concerns of soil erosion and landslide hazards in the Drava region. To accurately assess risks, the Surveying and Mapping Authority of Slovenia provided national LiDAR-derived Digital Terrain Models (DTM) with 1-metre resolution. This authoritative elevation dataset enabled detailed evaluation of hazard zones across Maribor and Cirkulane, covering nearly 300 km². The analysis revealed that around 20% of the region faced moderate to severe soil erosion risk, while landslide susceptibility was generally very low, with only a few localised areas identified as high risk. The study demonstrated the effectiveness of integrating national geospatial data with Copernicus EMS Risk and Recovery Mapping, ensuring timely and evidence-based decision-making.
