Engel, F.L., Cadogan, A., and Duan, J.G., 2022, Small Unoccupied Aircraft System Imagery and Associated Data used for Discharge Measurement at Eight Locations Across the United States in 2019 and 2020: U.S. Geological Survey data release, https://doi.org/10.5066/P9H2MM1M.
Summary
This child item contains the raw acoustic Doppler velocity profiler (ADCP) and acoustic Doppler velocimeter (ADV) measurements collected by U.S. Geological hydrographers at each site for the purpose of validating LSPIV results. In all field sites except for the Androscoggin River (ACR) and Agua Fria River (AFR) sites, the discharge measurements were collected as part of routine and standard U.S Geological streamflow gaging direct measurement workflows at established U.S. Geological Survey gaging locations. The discharge measurement at the Androscoggin River (ACR) site was collected in a reach of river not containing a U.S. Geological Survey stream gage, however it was collected using the standard gaging workflows. The discharge measurement [...]
Summary
This child item contains the raw acoustic Doppler velocity profiler (ADCP) and acoustic Doppler velocimeter (ADV) measurements collected by U.S. Geological hydrographers at each site for the purpose of validating LSPIV results. In all field sites except for the Androscoggin River (ACR) and Agua Fria River (AFR) sites, the discharge measurements were collected as part of routine and standard U.S Geological streamflow gaging direct measurement workflows at established U.S. Geological Survey gaging locations. The discharge measurement at the Androscoggin River (ACR) site was collected in a reach of river not containing a U.S. Geological Survey stream gage, however it was collected using the standard gaging workflows. The discharge measurement at the Agua Fria (AFR) site was completed after the event as an indirect Continuous Slope-Area (CSA) measurement (see FGDC metadata Process Steps for details). The zip file included in this release contains folders for each site. Within each folder is the associated raw ADCP or ADV discharge files or resulting CSA summary file. Each discharge measurement folder also includes a portable document format (PDF) file of the default "Discharge Summary" report produced by the native ADCP or ADV collection software. Each discharge measurement folder (except the ACR folder) also contains 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 U.S. Geological Survey Database. For example, the Coachella Canal (CCC) discharge measurement was located at U.S. Geological Survey gage number 09527590, and was measurement number 246 in the National Water Information System (NWIS) database. The text file for this measurement is named "09527590_QM246_NWIS.txt". The other sites contain similarly formatted text files. Each Field Site is abbreviated in various files in this data release. File and folder names are used to quickly identify which site a particular file or dataset represents. The following abbreviations are used:
ACR: Androscoggin River, Auburn, Maine, USA
AFR: Agua Fria River, near Rock Springs, Arizona, USA
CCC: Coachella Canal above All-American Canal Diversion, California, USA
CMC: Cochiti East Side Main Channel, near Cochiti, New Mexico, USA
GLR: Gila River near Dome, Arizona, USA RMC: Reservation Main Canal near Yuma, Arizona, USA
SMC: Sile Main Canal (at head) at Cochiti, New Mexico, USA
WMD: Wellton-Mohawk Main Outlet Drain near Yuma, Arizona, USA

Purpose
These data were collected as part of a series of field experiments to test the validity of using small unoccupied aircraft systems (sUAS) to collect stream surface velocity and discharge measurements. The data included here represent the raw sensor measurements (or post event indirect measurement) of stream discharge at each field site, which can be used to validate the results or Particle Image Velocimetry analysis.
