Unoccupied Aerial System-mounted image velocimetry and Doppler velocity radar data for computation of river velocity and discharge collected at seven locations in Colorado in 2023: Discharge Measurements

This child item contains the raw acoustic Doppler velocity profiler (ADCP) measurements collected by U.S. Geological Survey (USGS) hydrographers at each site to validate Image and Radar velocimetry results. The discharge measurements were collected as part of routine and standard streamflow gaging direct measurement workflows at established USGS gaging locations. The zip file included in this release contains folders for each site. Within each folder are the associated raw ADCP files. For all field sites except BRJ, official discharge records are approved and available in the National Water Information System (NWIS) database. For those measurements with NWIS official measurements, the Site Visit Notes report is included (portable document files [PDF] starting with "SV_"). Also included for each official measurement is an empty text file with the USGS gage station ID, discharge measurement number, and database abbreviation so that users can reference the approved discharge measurement in the USGS database. For example, the Colorado River below Glenwood Springs, CO (CRG) discharge measurement was located at USGS gage number 09085100. It was measurement number 577 in the NWIS database. The text file for this measurement is named "09085100_QM577_NWIS.txt". The other sites contain similarly formatted text files. To aid in validation of streamflow and velocity, summary files that include ADCP velocities summarized on a station/vertical basis extracted from the discharge measurements are also included as *_summary.csv files. <br> Each field site is abbreviated in various files in this data release. File and folder names quickly identify which site a particular file or dataset represents. The following abbreviations are used: <ul> <li>ACS: Anthracite Creek at Somerset, Colorado, USA</li> <li>BRA: Blue River below Dillon, Colorado, USA (collected in August 2023)</li> <li>BRJ: Blue River below Dillon, Colorado, USA (collected in June 2023)</li> <li>CRG: Colorado River below Glenwood Springs, Colorado, USA</li> <li>CRR: Colorado River above Roaring Fork River at Glenwood Springs, Colorado, USA</li> <li>ERW: Eagle River below Milk Creek near Wolcott, Colorado, USA</li> <li>MCA: Maroon Creek near Aspen, Colorado, USA</li> <li>RFG: Roaring Fork at Glenwood Springs, Colorado, USA</li> </ul>
