As the boundary layer is generally higher everywhere on Arrakis the average dune height is in general twice that of Earths. It typically takes the form of a mound, ridge, or hill. Compound parabolic dunes are coalesced features with several sets of trailing arms. They are ubiquitous in natural channels such as rivers and estuaries, and also form in engineered canals and pipelines. Before the movie was released, we took a scientific climate model and used it to simulate the climate of Arrakis.

They range up to 300m (980ft) in height and 300km (190mi) in length. The pink colored sand that makes this place unique is due to the erosion of the sandstone by the wind, which has been blowing between the Moquith and Moccasin mountains for nearly 15,000 years, dislodging grains of sand from the sandstone rocks and depositing them in this valley.

In regards to "sand dunes" they migrate in the direction of the [50], There are many threats to these coastal communities. Duna Federico Kirbus is part of a sand valley that takes the name of Bolsn de Fiambal, and it's globally recognized as the highest sand dune in the world. [33] They are thought to be more ancient and slower-moving than smaller dunes,[25] and to form by vertical growth of existing dunes. Transverse dunes lie perpendicular to the wind, which moves them forwards, producing the cross-bedding shown here. Draas are widespread in sand seas and are well-represented in the geological record.[33]. Coastal dunes[35] form when wet sand is deposited along the coast and dries out and is blown along the beach.
