A Case Study of Moving Sand Dunes: The Barchans of the Kharga Oasis

Author(s): Amelia Carolina Sparavigna

Recently we have proposed the use of the time series of Google Earth to investigate the motion of sand dunes. In this paper we consider a case study, applying the method to some barchans of the Kharga Oasis. To evaluate the motion of these dunes as a function of their size we use Gimp, a GNU image processing software.
