Hydro-morphological mapping of river reaches using videos captured with UAS

Anette Eltner et al.

Summary: Unmanned aerial systems (UASs) are commonly utilized in fluvial geomorphology for their ability to capture continuous data. This study introduces a (semi-)automated workflow for measuring river bathymetry and surface flow velocities using UAS videos and imagery. By combining video frame filtering, structure from motion (SfM) photogrammetry, and image velocimetry analysis, the workflow accurately estimates flow patterns and discharge, providing valuable input for hydro-morphological models.
