Resource Abstract:
- description: These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in ASCII format,
generated from hydrographic and velocimetric surveys of the Missouri River near highway bridge structures on U.S. Highway
40 near St. Louis, Missouri, in 2010, 2011, and 2016. 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 computer software to extract bathymetry
data from the raw data files and to summarize and map the information. Velocity data were collected using an acoustic Doppler
current profiler (ADCP) mounted on a survey vessel equipped with a differential global positioning system (DGPS). Data were
collected as the vessel traversed the river along planned transect lines distributed throughout the reach. Velocity data were
processed using the Velocity Mapping Toolbox (Parsons and other, 2013), and smoothed using neighboring nodes.; abstract: These
