One of our approaches for river monitoring in the TEMBO project includes image velocimetry using OpenRiverCam for river velocity estimation, dry bed bathymetry using photogrammetry in OpenDroneMap, and wet bed bathymetry using sonar via a fish finder. Work to date has piloted this approach at three locations in Ghana within the Black Volta Basin. Some visualization of this work is available in this preliminary video introducing the work.
