Velocity and water-surface elevation measurements from the Lazy Day reach of the Big Piney River, near St. Robert, Missouri
This dataset includes 5 sets of velocity measurements and water-surface elevation measurements collected at the Lazy Day (LD) reach on the Big Piney River near St. Robert, Missouri between November 19, 2020 and August 25, 2021. Velocity data were collected by USGS staff from the Columbia Environmental Research Center at different locations in the study reach using an acoustic Doppler current profiler (ADCP) and Real Time Kinematic Global Navigation Satellite Systems (RTK GNSS) positioning. Data were used to evaluate the calibration performance of a one-dimensional hydraulic model of the LD reach. Velocity data are provided as mean velocity at distances along a stream centerline that corresponds to the one-dimensional hydraulic modeling reach in HEC-RAS. Water-surface elevation data were collected by USGS staff from the Columbia Environmental Research Center using RTK GPS for the length of the study reach. Data were used to calibrate a one-dimensional hydraulic model of the LD reach. Water surface elevations are provided at distances along a stream centerline that corresponds to the one-dimensional hydraulic modeling reach in HEC-RAS.

Hydraulic calibration results for the Lazy Day reach of the Big Piney River, near St. Robert, Missouri
공공데이터포털
This dataset includes the discharge values and calibration results for five discharge measurements collected at the Lazy Day (LD) reach on the Big Piney River near St. Robert, Missouri between November 19, 2020 and August 25, 2021. 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 LD reach.

Water-surface elevation measurements for four reaches of the Big River, Missouri
공공데이터포털
Water-surface elevation measurements were performed for a range of flow events up to bankfull discharge within four reaches of the Big River, Missouri. The study reaches are Site W (STW), Rockford Beach (RFB), Phelps Bend (PHB), and Washington State Park (WSP). The water-surface elevation measurements were collected to provide hydraulic model calibration data in support of research assessing the hydraulic conditions of freshwater mussel habitat in the Big River. Data were collected either manually or by boat in the study reaches using a Global Navigation Satellite System (GNSS) receiver. Calibration data also included water-surface elevation data from bathymetry and terrestrial lidar surveys. Models were calibrated by adjusting the input parameters until the simulated water-surface elevations throughout the reach most closely matched the observed water-surface elevations, by minimizing root mean squared error (RMSE).
