Huizinga, R.J., 2019, Bathymetric data at highway bridges crossing the lower Gasconade River after the May 2017 flood in central Missouri (ver. 2.0, May 2019): U.S. Geological Survey data release,


These data are high-resolution bathymetry (riverbed elevation) in ASCII format, generated from hydrographic surveys near six highway bridge structures over the Gasconade River in central Missouri. These sites were surveyed in June 2017 to help identify possible effects from extreme flooding on May 1-2, 2017. At the five downstream sites, 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 [...]

Hydrographic data were collected 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 any scour countermeasures in place around the bridge foundations.
