The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification. These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.

Geomorphic changes resulting from floods in reconfigured gravel-bed river channels in Colorado, USA
- Overview
The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification. These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.

Reconfigured Channel Monitoring and Assessment Program (RCMAP)
Channel reconfiguration to mitigate a variety of riverine problems has become an important issue in the Western United States. Reasons cited for channel reconfiguration include restoration to more natural or historical conditions, improved water conveyance in flood-prone areas, mitigation of unstable streambed and streambanks, increased sediment transport, and enhancement of riparian habitat or...RCMAP - Muddy Creek below Wolford Mountain Reservoir near Kremmling, Colorado

Geomorphic changes resulting from floods in reconfigured gravel-bed river channels in Colorado, USA
Geomorphic changes in reconfi gured reaches of three Colorado rivers in response to floods in 2005 provide a benchmark for "restoration" assessment. Sedimententrainment potential is expressed as the ratio of the shear stress from the 2 yr, 5 yr, 10 yr, and 2005 floods to the critical shear stress for sediment. Some observed response was explained by the excess of flood shear stress relative to the
