Site 22 Missouri River Bathymetry Data at Structure K0969 on Missouri State Highway 47 at Washington, Missouri, July 2011 and April 2013

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 Structure K0969 on Missouri State Highway 47 at Washington, Missouri, in 2011 and 2013. 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 [...]
