Drone usage for Rivers

4K images dozen of meters above water surface allow for tracking the flow speed in this confluence, the change in velocity determines the driving forces (Newton´s 2nd Law) and the prediction of effects and control measurements. Drone videos and further image processing are affordable tools for real scale studies.

4K  Images during this year first rise, flights were stable and the resolution pretty much fine.

Limitations, accuracy, Ground Control Points support, Structure from Motion, what can be done at the moment ? Latest research available at:  https://www.mdpi.com/journal/drones/special_issues/DroTop

No wind, clear sky, and all dry for the moment. As you can guess ... the first drill is to fly below the bridge, go and return !

Testing a DJI Mavic 2 Zoom to feel familiar with stable heights, angles and video parameters, although January is usually windy at Saragosse and wind speeds over 10 m/s are not secure, as happens now; current wind speed map provided by darksky.net .
