Summary

These data are remote sensing image-based classification maps of unvegetated river-derived sand along the Colorado River. One map is based on imagery acquired in May 2013 and is a classification of sand located above the wetted river channel in the imagery which was acquired at the approximate contemporary low-flow river discharge of 8,000 cubic feet per second (227 cubic meters per second) and extends from Glen Canyon Dam at Lake Powell to Separation Canyon at Lake Mead, a total distance of approximately 255 river miles (410 river kilometer). Three other maps are based on imagery acquired in May 2002, 2009, and 2013, respectively, and are classifications of sand located above the wetted river channel (at river discharge of approximately [...]

Purpose

These data are intended to be useful for management, monitoring, and research of sediment-related resources in the Colorado River downstream of Glen Canyon Dam in Glen Canyon National Recreation Area and Grand Canyon National Park. These data can be used in GIS analyses and for change detection with other classification datasets to assess dynamics of sand distribution in the Colorado River ecosystem.
