Water velocities were measured in the lock chamber of Brandon Road Lock on the Des Plaines River at river mile 286 on December 10, 2014 using a Teledyne RDI Rio Grande 600 kHz acoustic Doppler current profiler (ADCP). The data were georeferenced with a differential GPS receiver with submeter accuracy. These velocity measurements were collected in support of the US Army Corps of Engineers Great Lakes and Mississippi River Interbasin Study (GLMRIS). Data were processed using the Velocity Mapping Toolbox (Parsons and others, 2013) to derive temporally- and spatially-averaged water velocity values. Parsons, D. R., Jackson, P. R., Czuba, J.

Water velocities were measured in the Illinois and Des Plaines Rivers using a Teledyne Rio Grande 1200 kHz acoustic Doppler current profiler (ADCP). ADCP data were collected in reciprocal pairs along cross-sections and along approximately streamwise-oriented lines between crosssections at the following locations: (1) the confluence of the Fox River and the Illinois River near Ottawa, IL on November 4, 2015 (2) immediately downstream of Starved Rock Lock and Dam on the Illinois River near Utica, IL on May 22, 2015 (3) the Dresden Island Pool of the Des Plaines River on July 31 – August 1, 2013 (4) the Marseilles Pool of the Illinois River on May 14-15, 2013 and May 28, 2013 The WinRiverII classic ASCII output file and KML files are provided for each ADCP transect. The classic ASCII output files may be imported into the Velocity Mapping Toolbox (https://hydroacoustics.usgs.gov/movingboat/VMT/VMT.shtml) for processing and visualization. The velocity data were collected as part of the GLRI velocity mapping project for the Illinois River.

Flow discharges were measured in the Des Plaines River from approximately river mile 286 to river mile 284 on October 19–21, 2015 using Teledyne Rio Grande 1200 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with differential GPS receivers with submeter accuracy. These flow discharge measurements were collected in support of the US Army Corps of Engineers Great Lakes and Mississippi River Interbasin Study (GLMRIS), and were concurrent with a dye-tracing study. The discharge measurements included here were collected in the following locations: immediately upstream, across, and immediately downstream of the NRG Energy Joliet Power Station right descending bank intake (North Intake) immediately upstream, across, and immediately downstream of the NRG Energy Joliet Power Station left descending bank intake (South Intake) immediately upstream, across, and immediately downstream of the NRG Energy Joliet Power Station right descending bank outfall (North Outfall) across the NRG Energy Joliet Power Station left descending bank outfall (South Outfall) ADCP data were collected and initially reviewed in the WinRiver II software. Final review of discharge measurements was completed using the QRev discharge computation and review software (Mueller, D. S., 2016). The output from QRev includes an XML document with the processed results, and is included here. A stylesheet (XLS) file is also included to enable easy viewing of the QRev processed results. Note that additional discharge measurements associated with the dye-tracing study were taken at the existing US Geological Gaging Station, Des Plaines River in Lock Channel at Rockdale, IL (05538020), and can be accessed with the links below. A KMZ archive containing the locations of the ADCP shiptracks for each discharge measurement are included, along with an associated metadata file.

Field measurements of flow velocity were acquired from a reach of the Illinois River at Marseilles, IL, on June 7, 2022, to support research on estimating surface flow velocities from remotely sensed data via particle image velocimetry (PIV). The velocity measurements included in this data release were obtained using a TRDI RiverPro acoustic Doppler current profiler (ADCP) deployed from a boat with an outboard motor. This data release provides depth-averaged flow velocities derived from the raw ADCP data using the TRDI WinRiver II processing software. The spatial location of each velocity measurement was obtained using a differential GPS included as part of the RiverPro instrument package. The map projection and datum for these data are UTM Zone 16 N and WGS84, respectively. This data release consists raw ADCP measurements of flow velocity, channel geometry, and river discharge, provided as raw *.mmt and *.pd0 files; output from Velocity Mapping Toolbox (VMT) for each ADCP cross-section provided as .xlsx files; and spatial coordinates and depth-averaged flow velocity magnitude and direction for each ADCP cross-section provided as a .csv file. This field-based data set was used to assess the accuracy of remotely sensed estimates of surface flow velocity derived from thermal image sequences via PIV.

ADCP data were collected on July 31-August 1, 2013 in the Dresden Island Pool on the Des Plaines River using a Teledyne Rio Grande 1200 kHz Acoustic Doppler Current Profiler with integrated Trimble Ag162 GPS. On July 31-August 1, 2013 the Des Plaines River discharge also was approximately 2,000-3,000 cfs. ADCP data was collected in reciprocal pairs along cross-sections and along roughly streamwise oriented lines between cross-sections. The data are provided in: (1) a zipped folder containing classic ascii output files exported from WinRiverII software, and a README text file indicating which files are reciprocal pairs, and which files are streamwise oriented lines (2) a zipped folder containing KML files for each transect

These data were collected using a 1200 kHz TRDI Rio Grande acoustic Doppler current profiler (ADCP) in mode 12 with 25 centimeter bins from a moving boat. The data were georeferenced with a Hemisphere Crescent A100 differential Global Positioning System (GPS) receiver with submeter accuracy. The data were processed in the Velocity Mapping Toolbox (Parsons and others, 2013) to obtain a mean velocity field for each cross section from four individual transects at each cross section. These data were collected by the U.S. Geological Survey (USGS) concurrently with environmental DNA (eDNA) sampling in this reach of the Chicago Sanitary and Ship Canal (CSSC) by the U.S. Fish and Wildlife Service (USFWS). NOTE: Any data assigned a value of "-9999" are bad or missing data and should not be used for analysis. Parsons, D. R., Jackson, P. R., Czuba, J. A., Engel, F. L., Rhoads, B. L., Oberg, K.

Flow discharges were measured in the Des Plaines River immediately downstream of the Brandon Road Lock at river mile 286 on December 9, 2014 a using Teledyne RDI Rio Grande 1200 kHz acoustic Doppler current profiler (ADCP). The data were georeferenced with a differential GPS receiver with submeter accuracy. These flow discharge measurements were collected in support of the US Army Corps of Engineers Great Lakes and Mississippi River Interbasin Study (GLMRIS). ADCP data were collected and initially reviewed in the WinRiver II software. Final review of discharge measurements was completed using the QRev discharge computation and review software version 3.35 (Mueller, 2016). The output from QRev includes an XML document with the processed results, and is included here. A stylesheet (XLS) file is also included to enable easy viewing of the QRev processed results.

The data collection for the concrete-walled channel downstream from the Brandon Road Lock and Dam near Joliet, Illinois occurred in May 2014 Five pounds per square inch (lb/in2) was used as a threshold water pressure value for this study as this value incorporates fish behavior and structural integrity considerations. The Brandon Road study evaluated the performance of two different water gun configurations within the concrete-walled channel downstream from the lock with depths ranging from 12-15 feet. Data from a single 80 cubic inch (in³) water gun produced a roughly cylindrical 5 lb/in2 pressure field 20 feet in radius, oriented vertically, with the radius decreasing to less than 15 feet at the surface. A combination of two 80-in³ water guns produced a similarly shaped 5 lb/in2 pressure field 30 feet in radius. Velocity and acceleration data were collected simultaneously with the underwater pressure data to understand the response of the adjacent channel walls to the water gun firings. Maximum values for velocity and acceleration were 0.239 inches per second (in/s) and 0.019 feet per second squared (ft/s²), respectively.

On August 31, 2015, U.S. Geological Survey Illinois Water Science Center staff deployed a 2000 kHz side-looking acoustic Doppler velocity meter (ADVM) in the Chicago Sanitary and Ship Canal (CSSC) at the Electric Dispersal Barrier System (EDBS). These data were collected as a fully loaded commercial barge tow traversed the EDBS and passed the ADVM three times, and as several smaller vessels and an unloaded barge tow passed the ADVM. The ADVM was mounted to a rigid 2-inch PVC pipe in compliance with U.S. Army Corps of Engineers (USACE) operational safety protocols for working in or near the EDBS. The pipe with ADVM was lowered 4.5 feet below the water surface on the west (right) bank of the canal at a location approximately 477 feet upstream of the Romeo Road (135th Street) bridge (41.642050, -88.060383). The pipe was mounted to the walkway guard rail in a vertical orientation. An upstream and downstream guide line were used to provide additional tension to prevent movement or vibration on the PVC pipe. In this deployment configuration, the ADVM was profiling from the right wall of the canal out towards the center of the channel. ADVM data were viewed in real-time on a laptop computer during the deployment and logged simultaneously to the internal memory of the ADVM. The ADVM data were downloaded from the ADVM to a laptop computer while on site and reviewed briefly while in the field. Upon return to the USGS Illinois Water Science Center the ADVM data were downloaded from the field laptop and reviewed following standard USGS data quality assurance protocols.

These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in comma-delimited table format, generated from hydrographic and velocimetric surveys near highway bridge structures over the Missouri River between Kansas City and St. Louis, Missouri, May 19–26, 2021. Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which consists of a multibeam echosounder (MBES) and an inertial navigation system (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the river along planned survey lines distributed throughout the reach. Data collection software integrated and stored the depth data from the MBES and the horizontal and vertical position and attitude data of the vessel from the INS in real time. Data processing required specialized computer software to extract bathymetry data from the raw data files and to summarize and map the information. Velocity data for the surveys were collected using an acoustic Doppler current profiler (ADCP) mounted on a survey vessel equipped with a differential global positioning system (DGPS). Velocity data were collected for all sites except site 14 at Lexington due to a faulty ADCP unit. Data were collected as the vessel traversed the river along seven planned transect lines distributed throughout the reach. Velocity data were processed using the Velocity Mapping Toolbox (Parsons and others, 2013), and smoothed using neighboring nodes. There is a zip file for the 8 surveyed sites available for download containing the bathymetric data and depth-averaged velocities. The files follow the format of "site-##_MissouriRiver_HWY#_2021-05.zip", where "site-##" is the site number from 14 to 21 and "HWY#" is the highway type and route number. The zip files each contain two comma-delimited text files, one with the bathymetry and uncertainty data and one with the depth-averaged velocity data, as well as associated metadata and thumbnail images.
