Riparian-vegetation controls on the spatial pattern of stream-channel instability, Little Piney Creek, Missouri Riparian-vegetation controls on the spatial pattern of stream-channel instability, Little Piney Creek, Missouri
The role of riparian vegetation is assessed quantitatively by using a five-decade record of valley bottom vegetation and channel dynamics developed from historical aerial photography. A 12-kilometer reach of a typical Ozarks stream was mapped using aerial photographs from 1938, 1948, 1955, 1965, 1976, and 1989; maps were then analyzed in a digital geographic information system. Analysis...

Historical land-use changes and potential effects on stream disturbance in the Ozark Plateaus, Missouri Historical land-use changes and potential effects on stream disturbance in the Ozark Plateaus, Missouri
Land-use changes have been blamed for creating disturbance in the morphology of streams in the Ozark Plateaus, Missouri (hereafter referred to as the "Ozarks"). Historical evidence and stratigraphic observations document that streams have been aggraded by substantial quantities of gravel beginning sometime at or near the time of European settlement of the Ozarks. Before European...

Geomorphic changes on the Mississippi River flood plain at Miller City, Illinois, as a result of the flood of 1993 Geomorphic changes on the Mississippi River flood plain at Miller City, Illinois, as a result of the flood of 1993
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...
