Geomorphic Changes Caused by the 2011 Flood at Selected Sites Along the Lower Missouri River and Comparison to Historical Floods. Chapter H of 2011 Floods of the Central United States.

摘要

An analysis of recent and historical U.S. Geological Survey streamgage information was used to assess geomorphic changes caused by the 2011 flood, in comparison to selected historical floods, at three streamgage sites along the lower Missouri River - Sioux City, Iowa; Omaha, Nebraska; and Kansas City, Missouri. Channel-width change was not evident at the three streamgage sites following the 2011 flood and likely was inhibited by bank stabilization. Pronounced changes in channel-bed elevation were indicated.
