How attractive is a barchan dune?

New Journal of Physics, 2009
The spatio-temporal behaviour of barchan dunes is investigated experimentally with downsized longitudinal barchan dune slices generated in a narrow water flow tube. The development towards a shape attractor is shown on the basis of four different starting configurations in qualitative observation and quantitative analysis.

Resultant Force on Grains of a Real Sand Dune: How to Measure It?

Geophysical Research Letters
Barchan dunes usually appear under the action of one‐directional fluid flows, being found on Earth, Mars, and other celestial bodies; however, although ubiquitous in nature, understanding dune dynamics at the grain scale is challenging due to the vast ...
