Definition
Relatively flat area between dunes.
Synonyms
Dune valley; Interdune areas filled by a lake are called Dund in India; Interdune horseshoe depressions between barchans or barchanoid ridges, especially where dunes are pressed closely on one another in such a way that the horns of one barchan join with the foot of the leeward dune, are called Fulji in Arabia (Glenn 1979); Open interdune corridors are called Couloir in North Africa
Subtypes
Transverse dune interdunes are classified into two groups (Baddock et al. 2007):
- (1)
Sandy interdunes with closely spaced dunes
- (2)
Extended interdunes where the interdune is considerably longer than the separation length
Description
The interdune corridor (interdune hollow or interdune area) is a continuous flat or gently sloping surface between dune ridges or rows of dunes (Figs. 1 and 2). They may be depositional features covered with a thin sheet of sand (sand sheet) or sand-free deflationary features exposing bedrock. Linear dunes are...
