The U.S. Geological Survey (USGS) is actively investigating the use of innovative remote-sensing techniques to estimate surface velocity and discharge of rivers in ungaged basins and river reaches that lack the infrastructure to install conventional streamgaging equipment. By coupling discharge algorithms and sensors capable of measuring surface velocity, streamgage networks can be established in regions where data collection was previously impractical or impossible. One of the remote-sensing techniques uses a Doppler (velocity) radar (QCam) mounted and integrated on a small unmanned aircraft system (sUAS or drone). QCam measures the along-track surface velocity by spot dwelling in a river cross section at a vertical...

A USGS Unoccupied Aircraft Systems (UAS) Aquatic Airshow field testing and demonstration event occurred March 20–21, 2018, on the Arkansas River at Parkdale, CO, USA. At the airshow, a group of USGS scientists and technicians gathered to test non-contact sensors for measuring stream discharge using UAS and a sensor mounted on a tag line. Scientists at the event performed a series of tests to measure river discharge with experimental non-contact techniques. USGS scientists and field personnel traditionally conduct a discharge measurement either by wading or working from a boat. Due to the potential danger and high risk to personnel safety, hydrologic measurement work is limited during very high flow events, ice break-up,...

The U.S. Geological Survey is testing deployments of continuous Large-Scale particle Image Velocimetry (LSPIV) streamgaging stations in areas with flashy flow regimes to measure streamflow during flood events. Videos were collected for the purpose of LSPIV streamflow analysis at a stage-discharge streamgaging station in a small, flashy urban stream in Urbana, Illinois, USA (Boneyard Creek at Urbana, IL, 03337000) with an internet protocol (IP) camera. The IP camera is mounted on the bottom of a walkway bridge spanning the creek at the gaging location, and is aimed to view the water for optimal camera perspective at all flow stages. Videos of peak streamflow events with gage height above 12 feet (local gage datum)...

Near-field remote sensing methods were used to collect Doppler velocity and pulsed stage radar data at 10 conventional U.S. Geological Survey streamgages in river reaches with varying hydrologic and hydraulic characteristics. Basin sizes ranged from 381 to 66,200 square kilometers and included agricultural, desert, forest, mixed, and high-gradient mountain environments. During the siting and operational phases, radar-derived mean-channel (mean) velocity and discharge were computed using the Probability Concept (PC) and were compared against conventional instantaneous measurements and stage-discharge time series. During siting phase, radars were located, installed, and PC parameters computed. To test the efficacy...

A series of field measurements of surface water velocity derived from video collected by small unoccupied aircraft systems (sUAS) was conducted at eight locations in Arizona, New Mexico, California, and Maine, USA during the summers of 2019 and 2020. The measurements are utilized to compute surface velocity and discharge using the Large-Scale Particle Image Velocimetry (LSPIV) image velocimetry method. This data release includes the original video and subsequent processing results of this analysis. Data are grouped into sections (child items) based on the data type and purpose: Ancillary Scripts: this child item contains Mathworks MATLAB script files which reproduce the processing steps for each dataset. Additional...
