Post-fire hydrological analysis; Czech Bohemian Switzerland national park

Abstract

In 2022, Bohemian Switzerland National Park experienced the largest wildfire in the recent history of the Czech Republic, affecting over 1,000 hectares. The aim of this study was to perform a hydrological assessment of the post-fire conditions in the Sucha Bela sub-basin, located in the park, using the HEC-HMS software package. Rainfall–runoff relationship data and landscape classification data specific to the Sucha Bela sub-basin were categorized using Sentinel-2 imagery and local surveys. The results showed that the forest fire temporarily affected the soil infiltration capacity and therefore influenced runoff.
