Incipient Bed-Movement and Flood-Frequency Analysis Using Hydrophones to Estimate Flushing Flows on the Upper Colorado River, Colorado, 2019

In an effort to better understand sediment movement and its relation to flow regimes of the Upper Colorado River in Colorado, in 2019, the U.S. Geological Survey, in cooperation with the Upper Colorado River Wild and Scenic Stakeholder Group, studied the magnitude and recurrence interval of streamflow (discharge) needed to initiate bed movement of gravel-sized and finer sediment in a segment of...

Fountain Creek Watershed Flood and Sediment Transport Study

The Fountain Creek watershed, Colorado, is characterized by steep channel slopes and varied land use. Spatially distributed precipitation events result in varying rates of direct runoff. These dynamics contribute to large streamflows and sediment transport, which has caused periodic flooding, and sediment aggradation and deposition in Fountain Creek and its tributary streams. The U.S. Geological...

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 - Lake Fork of the Gunnison near Lake City, Colorado

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.

Lower Yampa Streamflow and Sediment Modeling

Water from the Yampa River basin continues to be sought for a number of municipal, industrial, and energy uses. Water development in the Yampa River basin will alter the streamflow regime and, consequently, will lead to changes in the transport and storage of suspended and bedload sediment. Changes in the Yampa River sediment budget could lead to changes in channel geometry, riparian vegetation...

Gunnison and Green River Basin Sediment Monitoring and Evaluation Program

Underlying geomorphic processes relevant to the formation and maintenance of backwater habitats are relatively poorly understood, particularly the effects of peak-flow magnitude and duration; sediment deposition and erosion; base-flow magnitude and variability; and antecedent conditions on habitat availability and conditions. Knowledge of sediment dynamics in important river reaches is critical to...
