Pronunciation edit
Noun edit
barchan (plural barchans)
- An arc-shaped sand ridge comprising well-sorted sand.
- 1966, Edwin Sherbon Hills, Arid Lands: A Geographical Appraisal[1], page 72:
- The sand is usually very well sorted in barchans, for it is constantly re-worked as the dune ‘marches’. The marching also causes cross-bedding inside the barchan, with a dip parallel to the sand-fall face.
- 1988, Robert Irwin, The Mysteries of Algiers, Dedalus, published 1993, page 69:
- But to follow the dunes around the foot of their slopes is also tedious and one can walk for half a kilometre east or west, finding one barchan linked to another and no easy way through […] .
- 2008, Julie Laity, Deserts and Desert Environments[2], page 205:
- Barchans and transverse dunes are essentially of the same type, forming and migrating under a unidirectional wind regime. The difference between the two is related to the amount of sand: barchans are isolated mounds, whereas transverse dunes are composed of many barchans coalesced into a single, longer dune form (Tsoar 2001).
- 2010, Robert S. Anderson, Suzanne P. Anderson, Geomorphology: The Mechanics and Chemistry of Landscapes[3], page 482:
- Perhaps the most distinctive is the barchan dune, an isolated crescentic form with arms that stretch downwind. Barchans are not huge, often with heights of only a few meters.
