USGS Monitoring and Analysis of River and Stream Restoration Projects

Many rivers and streams in the United States have been mechanically reconfigured in an attempt to "restore" or modify the channel's function or habitat. However, the long-term performance of these projects usually is not evaluated in a consistent way. Several reconfigured rivers in Colorado are being monitored and their geomorphic responses to floods are being assessed by the USGS Colorado Water Science Center.
