During the 1993 floods on the upper Mississippi and Missouri rivers, the most dramatic changes to floodplains occurred at levee-break complexes where large discharges were concentrated through narrow breaks in levees. Scour and deposition associated with levee breaks adversely affected large areas of formerly productive bottomland. This case study of the levee-break complex at Miller City, Illinois, documents the geomorphic effects of a typical levee-break complex.
