Summary
These topographic/bathymetric digital elevation models (DEMs) were collected and compiled to characterize erosion and deposition in the Colorado River and in an adjacent zone of laterally recirculating flow (eddy) during both average flow conditions and during a controlled flood that occurred in March 2008. The objectives of the study were to measure changes sandbar morphology that occurred during changes in discharge associated with the controlled flood. These data were collected between February 6 and March 31, 2008 in a 1-mile study reach on the Colorado River within Grand Canyon National Park beginning 44.5 miles downstream from Lees Ferry, Arizona. These data were collected by the USGS Grand Canyon Monitoring and Research Center [...]

These data were collected by the USGS Grand Canyon Monitoring and Research Center with cooperators from Northern Arizona University and funding provided by the Glen Canyon Dam Adaptive Management Program. All bathymetric data were collected with a multibeam sonar system (Reson Seabat 8124 sonar with TSS MAHRSS reference system for heave, pitch, roll, and heading). Topographic data were collected by conventional total station. These data can be used to study changes in channel morphology associated with changes in streamflow conditions.

An eddy-resolving numerical model to study turbulent flow, sediment, and bed evolution using Detached Eddy Simulation in a lateral separation zone at the field-scale.

The purpose of these data is to better understand the relation between discharge, streamflow velocity, and sediment transport for use in predictive models of sediment transport and deposition and erosion. These data were created to test predictions of sediment erosion and deposition for the March 2008 controlled flood released from Glen Canyon Dam. It was also anticipated that these data would be used to build and calibrate future models for streamflow and sediment transport.
