Figure 5: Comparison of giant linear dune features in major terrestrial sand seas.
From: Unravelling raked linear dunes to explain the coexistence of bedforms in complex dunefields
(a) Erg Chech desert, Mali (24°43′ N, 3°39′ W). (b) Rub’al-Khali desert, Saudi Arabia (20°51′ N, 54°09′ E). (c) Namib desert, Namibia (24°15′ S, 14°59′ E). Despite similar raked patterns, we cannot conclude at this stage that these dunes are in a steady state or in equilibrium with the current wind regime. Given their size and location along major sand flow paths, they can also result from transition in dune shape across space and over time.
