Fluvial processes and passive rehabilitation of the Lisbon Bottom side-channel chute, Lower Missouri River Fluvial processes and passive rehabilitation of the Lisbon Bottom side-channel chute, Lower Missouri River
Multiple large floods in 1993-1997 on the Lower Missouri River carved a side-channel chute through the river bottom at Lisbon, Missouri. Although similar in some respects to engineered side-channel chutes designed for habitat rehabilitation projects, the Lisbon Bottom chute has been unique in that it was allowed to evolve for more than four years with minimal stabilization. During the...

Land-use changes and the physical habitat of streams - a review with emphasis on studies within the U.S. Geological Survey Federal-State Cooperative Program Land-use changes and the physical habitat of streams - a review with emphasis on studies within the U.S. Geological Survey Federal-State Cooperative Program
Understanding the links between land-use changes and physical stream habitat responses is of increasing importance to guide resource management and stream restoration strategies. Transmission of runoff and sediment to streams can involve complex responses of drainage basins, including time lags, thresholds, and cumulative effects. Land-use induced runoff and sediment yield often combine...

Relations among geology, physiography, land use, and stream habitat conditions in the Buffalo and Current River systems, Missouri and Arkansas Relations among geology, physiography, land use, and stream habitat conditions in the Buffalo and Current River systems, Missouri and Arkansas
This study investigated links between drainage-basin characteristics and stream habitat conditions in the Buffalo National River, Arkansas and the Ozark National Scenic Riverways, Missouri. It was designed as an associative study - the two parks were divided into their principle tributary drainage basins and then basin-scale and stream-habitat data sets were gathered and compared between...

Physical setting: Chapter 1 in Initial biotic survey of Lisbon Bottom, Big Muddy National Fish and Wildlife Refuge Physical setting: Chapter 1 in Initial biotic survey of Lisbon Bottom, Big Muddy National Fish and Wildlife Refuge
Lisbon Bottom consists of approximately 875 ha of river bottom along the Missouri River in Howard County, Missouri, from approximately river mile (RM) 213 to RM 219. As used in this report, the Lisbon Bottom area also includes the main channel of the Missouri River adjacent to the Lisbon Bottom and portions of the adjacent flood plain in Saline County, Missouri. Before regulation and...

Gravel sediment routing from widespread, low-intensity landscape disturbance, Current River basin, Missouri Gravel sediment routing from widespread, low-intensity landscape disturbance, Current River basin, Missouri
During the last 160 years, land-use changes in the Ozarks have had the potential to cause widespread, low-intensity delivery of excess amounts of gravel-sized sediment to stream channels. Previous studies have indicated that this excess gravel bedload is moving in wave-like forms through Ozarks drainage basins. The longitudinal, areal distribution of gravel bars along 160 km of the...
