Assessment of Floodplain Vulnerability during Extreme Mississippi River Flood 2011
Regional
change in the variability and magnitude of flooding could
be a major consequence of future global climate change. Extreme floods
have the capacity to rapidly transform landscapes and expose landscape
vulnerabilities through highly variable spatial patterns of inundation,
erosion, and deposition. We use the historic activation of the Birds
Point-New Madrid Floodway during the Mississippi and Ohio River Flooding
of 2011 as a scientifically unique stress experiment to analyze indicators
of floodplain vulnerability. We use pre- and postflood airborne Light
Detection and Ranging data sets to locate erosional and depositional
hotspots over the 540 km<sup>2</sup> agricultural Floodway. While
riparian vegetation between the river and the main levee breach likely
prevented widespread deposition, localized scour and deposition occurred
near the levee breaches. Eroded gullies nearly 1 km in length were
observed at a low ridge of a relict meander scar of the Mississippi
River. Our flow modeling and spatial mapping analysis attributes this
vulnerability to a combination of erodible soils, flow acceleration
associated with legacy fluvial landforms, and a lack of woody vegetation
to anchor soil and enhance flow resistance. Results from this study
could guide future mitigation and adaptation measures in cases of
extreme flooding
