Summary

These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in ASCII format, generated from hydrographic and velocimetric surveys of the Mississippi River near structure A6500 on Interstate 70 in St. Louis, Missouri, in 2009 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 [...]

Purpose

Hydrographic and velocity data were collected along planned survey lines within the study area to capture the hydraulic and geomorphological characteristics of the river. These data are intended for science researchers, policy makers, and hydraulic engineers interested in assessing the condition of the channel bed and the scour countermeasures in place around the bridge foundations.
