Official Flood Zones - Slovenia

The Official Flood Zones – Slovenia dataset is a national vector layer delineating areas
exposed to fluvial (river) flooding at multiple return periods, produced in compliance
with the EU Floods Directive (2007/60/EC) by Slovenian authorities. The dataset maps
the spatial extent of flood inundation across three hazard classes from High (10-year)
to Low (500-year). It is essential for flood risk assessment, insurance exposure
modelling, urban planning, and regulatory compliance with national and EU-level flood
hazard mapping requirements.

Technical information

Data coincides with the actual GeoNetwork catalog record - this is our most recent verified data.

Interpreting the data

each polygon is classified by its return period attribute — lower
return periods indicate more frequent, higher-probability flood events; higher return
periods indicate rarer but potentially more severe events. Classes range from High
(10-year, 10% annual probability) through Moderate (100-year) to Low (500-year,
0.2% annual probability). The intensity score is inverted relative to return period so
that more frequent flooding scores higher.

Resolution and update frequency

vector polygons; accuracy depends on the source cartographic scale
(to be confirmed). Coverage limited to Slovenia. Aligned with EU Floods Directive flood
hazard map reporting cycles.
