Discharge measurements were collected by USGS staff from the Columbia Environmental Research Center using an acoustic Doppler current profiler (ADCP) and Real Time Kinematic Global Navigation Satellite Systems (RTK GNSS) positioning. Calibration was performed to produce optimal values of downstream water-surface slope and Manning's roughness (Manning's n) for a one-dimensional hydraulic model of the WB reach. These hydraulic model calibration equations were produced in support of research examining the transport of freshwater mussel environmental DNA in rivers. 20210414 20210908 ground condition Complete None planned -83.04440 -83.00090 36.58770 36.56650 ISO 19115 Topic Category geoscientificInformation USGS Thesaurus hydrology stream discharge river reaches acoustic doppler current profiling USGS Metadata Identifier USGS:63237f84d34e71c6d67acbb9 Common geographic areas Tennessee Hancock County None.

The files were produced on a computer with a Windows 10 operating system. The files are < 1 kilobyte in size. No formal attribute accuracy tests were conducted All values fall within logical ranges Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. All horizontal positions were collected in Real-Time Kinematic (RTK)-fixed integer solution status. A formal accuracy assessment of the vertical positional information in the data set has not been conducted. All vertical positions were collected in Real-Time Kinematic (RTK)-fixed integer solution status. Calibration procedures yielded a single optimal downstream water-surface slope value across the range of calibrated discharges. The calibrated values for Manning's roughness in the active channel and the measured upstream water-surface elevation values for the main stem and the North Fork tributary were used to create regression relationships between discharge and each parameter. These curves were generated by fitting power law or linear functions to the calibrated values. 20220527 WB_Manning_roughness_equation.txt Calibration equation for Manning's roughness (Manning's n) at the WB reach.
