Bathymetric and velocimetric surveys at highway bridges crossing the Missouri River in and into Missouri during summer flooding, July-August 2011

Abstract

Map showing bathymetric survey of the Missouri River channel in the vicinity of structures 435-105-11.97 (235) and 435-105-11.98 (240) on Interstate 435 near Kansas City, Missouri ...

Bathymetric and velocimetric surveys at highway bridges crossing the Missouri River near Kansas City, Missouri, June 2–4, 2015

“…These data also may be used by MoDOT as a low to moderate flood flow comparison to help assess the bridges for stability and integrity issues with respect to bridge scour. Comparison of results to previous surveys at the sites (Huizinga, 2010(Huizinga, , 2012 also are provided.…”

“…1), and entails 8 bridges at 7 crossings (table 1). Two bridges at one crossing that were part of the previous surveys in Kansas City (structures K0456 and A0450 on U.S. Highway 69; Huizinga, 2010Huizinga, , 2012Huizinga, ) currently (2015 are being replaced and were not surveyed as part of this study (table 1); however, one bridge that was surveyed as part of the series during the 2011 flood study (structure A7650 on Interstate 29; Huizinga, 2012) is included in the current study.…”

“…The various components of the MBMS used for this study are described in reports about studies on the Missouri and Mississippi Rivers in Missouri (Huizinga, 2010(Huizinga, , 2012(Huizinga, , 2015Huizinga and others, 2010) and on the Missouri and Yellowstone Rivers in North Dakota (Densmore and others, 2013). The survey methods used to obtain the data were similar to these previous studies, as were the measures used to ensure data quality.…”

“…The river is highly channelized in the Kansas City area, with rock revetment and spur dikes along the banks to maintain the channel alignment, and levees and floodwalls on the upper banks to limit flooding in the industrial, commercial, and agricultural areas on the flood plains. The site numbering sequence used in Huizinga (2012) is used in this report for consistency and comparability.…”

“…In March 2010, 9 highway bridges at 7 crossings over the Missouri River near Kansas City, Missouri, were assessed using the MBMS (Huizinga, 2010); and in October 2010, 12 highway bridges at 7 crossings over the Missouri and Mississippi Rivers near St. Louis, Mo., were assessed . During high-flow conditions in June-August 2011, many of the highway bridges and several of the railroad bridges along the entirety of the Missouri River downstream from Montana were assessed (Densmore and others, 2013;Dietsch and others, 2014), including the 37 highway bridges (at 28 crossings) that span the Missouri River in and into Missouri (Huizinga, 2012). In April and May 2013, 10 highway bridges at 9 crossings over the Missouri River between Kansas City and St. Louis, Mo., were assessed as part of more routine, nonflood surveys at bridge sites in and into Missouri .…”
