Videos and imagery collected of the Arkansas River at Parkdale, CO on March 20–21, 2018 as part of the US Geological Survey (USGS) "2018 Airshow". These videos capture ground conditions of river flow at three locations in the vicinity of the USGS 07094500 Arkansas River at Parkdale, CO streamgage. The videos were captured by either a tripod-mounted digital camera, smartphone, or unmanned aerial system. All videos are named according to the date, time, and location of acquisition. Included with each video is an image with annotation indicating ground control points. The absolute distances between each ground control points are described in the included "Sensor_Cameras.csv" table on which this metadata is based. ...

The U.S. Geological Survey contracted with Juniper Unmanned to conduct field tests of the Infrared Cameras Inc. (ICI) Mirage camera on the Blue River just upstream of its confluence with the Colorado River near Kremmling, Colorado, on October 18, 2018. The objective of this project was to assess the potential to infer surface flow velocities in rivers by applying a particle image velocimetry (PIV) algorithm to aerial thermal infrared image time series collected from an unmanned aircraft system (UAS). The ICI Mirage (3-5 µm thermal IR) and a Sony DSC QX-30 (natural color) cameras were mounted on a Gremsy H7 gimbal, integrated with the ICI sensor control module (SCM), and mounted to a DJI Matrice 600 Pro UAS owned...

A variety of new technologies are being evaluated to mitigate the spread of invasive carps from the Illinois River to the Great Lakes. In 2022, the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and U.S. Geological Survey undertook a field-scale interagency study to determine the efficacy of an Automated Barge Clearing Deterrent (ABCD) in flushing live fish away from commercial barge vessels entering Peoria Lock on the Illinois River. The ABCD is a forced air manifold system that is placed at the channel bed to create a longitudinal array of bubble plumes. Illinois Department of Natural Resources (IDNR) staff operated a DJI Phantom 4 Pro v2.0 small uncrewed aerial system (sUAS) during a demonstration...
