IN the preceding chapter we examined the longitudinal cross- section, cut parallel to a uni-directional wind, of an imaginary transverse dune whose length was so great that the end-effects could be neglected. We saw that as this cross-section grows bigger there comes a time when the initial rounded shape is no longer stable; the top advances faster ...

The Journal of Geology, 1959
The crescentic sand-dune formation known as the "barchan" occurs extensively in the desert coast of southern Peru. Quantitative measurements were made on 75 of these to determine relationships between height, width, and length of horns. A consistently longer west horn was measured in most of the barchans, but this distortion cannot be readily explained.

The ecology of Qatari barchan dunes
Qatar Foundation Annual Research Forum Volume 2013 Issue 1, 2013The mobile Barchan dunes in Qatar are restricted to the southeastern region of the country. They are currently a disappearing natural habitat, due to the northwesterly Al Shamal winds which are scouring the landscape and spreading desertification as they pass. The study's aim was to understand the ecology of an active dune, in terms of resident species
