Summary edit
| Description |
English: Swift water sampling. This video demonstrates how you can collect a water sample using a drone in very fast-flowing waters. In this case, the Verde River was flowing at about 5500 CFS - a flow that made it very difficult to sample.
Notice the shadow of the collector entering the frame at top left about half-way through the video. The rig is lowered into the river, flows downstream, and is extracted. When it extracts, it swings back to the upstream side of the drone, whereupon it's quickly lowered back into the water. This allows the rig ample time to sink and the vials to fill. Takes some practice, but as you can see, it works! Verde River Institute verderiverinstitute.org facebook.com/verderiver Verde River @ Clarkdale, Clarkdale, Arizona. Shot using a DJI Phantom 4 Pro quad-copter (drone). |
