Digital Elevation Models (DEM) Data 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... Tags: Arizona, Colorado River, Eminence Break, Eminence Break field site, Glen Canyon Dam, All tags...

The data were collected to monitor the effects of the operations of Glen Canyon Dam on sandbars, which are also recreational campsites. The data were collected by the US Geological Survey Grand Canyon Monitoring and Research Center in cooperation with Northern Arizona University. Funding for data collection, processing, and reporting has been provided by the Glen Canyon Dam Adaptive Management Program administered by the US Department of the Interior Bureau of Reclamation.

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). Profiles of suspended-sediment concentration were also collected and compiled to characterize suspended sediment in the Colorado River. These datasets were collected during both average flow conditions and during a controlled flood that occurred in March 2008. Objectives of the study were to measure...
