Validation of global elevation models using ICESat-2 LiDAR data for floodplain modeling in the Ukrainian Carpathians

Accurate topographic data underpin hydrological and floodplain modeling in mountainous environments where steep gradients and dense forest cover amplify vertical errors in global Digital Elevation Models (DEMs). This study performs a comprehensive validation of freely available DEMs — SRTM v3, NASAD...
