barchan or barkhan dune, is a crescent-shaped dune. The term was introduced in 1881 by Russian naturalist Alexander von Middendorf, for crescent-shaped sand dunes in Turkestan and other inland desert regions

Seif, a long, narrow sand dune or chain of dunes, generally oriented in a direction parallel to the prevailing wind or in a direction resulting from two or more winds blowing at acute angles to each other. The dune crest consists of a series of peaks and gaps, and the steep, or slip, face may change sides of the dune according to changes in wind direction.

Barchan is crescent-shaped dune.

Seif dune is also crescent shaped but it is long type.

When wind blows from one place to another it creates sand dunes. Barchan occurse around vegetation and rocks. But Seif dune breaks this creation. It breaks the Barchans shapes. Barchan creates own and wider but Seif dunes breaks by own blows and creatures own shapes with wider and longer.
