Resultant force on grains of a real sand dune: How to measure it?
Renato F. Miotto, Carlos A. Alvarez, Danilo S. Borges +2
Dunes are bedforms found on sandy terrains shaped by fluid flow on Earth, Mars, and other celestial bodies. Despite their prevalence, understanding dune dynamics at the grain scale…
