Extended Data Fig. 7: Distribution of dune aspect ratio (\(\it \lambda\)/H) for all rivers and dunes with different lee-side angles.

From: Dunes in the world’s big rivers are characterized by low-angle lee-side slopes and a complex shape

Extended Data Fig. 7

Statistics given for the mean and standard deviation (std dev.) for all rivers and dunes with lee-side angles \(<1{0}^{\circ }\), \(10-2{4}^{\circ }\) and \(>2{4}^{\circ }\), which are related to zones of no flow separation, developing flow separation, and permanent, fully developed flow separation. N represents the number of data points that fall within each category.
