Monitoring Planimetric and Volumetric Changes on Active Sand Dunes
Monitoring the crest of an active reversing dune revealed inconsistent movement to the east but consistent extension to the north from 2009 to 2013. Documenting both crest and dune shape is essential for a comprehensive record of sand redistribution activities.

Summary Monitoring the crest of an active reversing dune showed inconsistent movement to E, but extension to N (2009-2013). Documenting both crest and dune shape will provide a better record of how the sand is being actively redistributed.
