Description :
The present morphology of the Western Desert is a palimpsest of forms inherited from ancient, contrasted morphogenetic systems and responses to climatic changes. During the Quaternary, running water has played a comparatively minor role in the large-scale shaping of landforms and has been restricted to the numerous, but short pluvials with wadi erosion and deposition in the foreland of plateaus and escarpments, and playa mud formation in deflation hollows. For most of the Pleistocene, as for the present period, deflation is of prime importance.
