It details various dune classifications shaped by wind patterns and discusses the impact on human settlements, notably desertification. The page provides a global overview of notable dune locations and includes references to studies on dune management and fixation.

A predictable sequence of bedforms and structures for in response to unidirectional flows as a function of grain size, flow depth and velocity.

Desert deposits are characterized by thick sets of cross-bedded sandstones and a combination of evaporites, mud, gravel, and fluvial deposits in interdune areas.
