Visualization of map of riverbed and canyon walls in Grand Canyon

Visualization of map of riverbed and canyon walls near Navajo Bridge, 4.5 miles downstream from Lees Ferry, Arizona. River bathymetry was measured with multibeam sonar and topography was measured with a boat-mounted laser scanner. The data from this survey collected in April 2016 will be used to measure changes in sand storage on the river bed and to model streamflow and sand transport.
