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...
