Wind-invariant saltation heights imply linear scaling of aeolian saltation flux with shear stress

RL Martin, JF Kok - Science advances, 2017 - science.org

B Andreotti, P Claudin, JJ Iversen… - Proceedings of the …, 2021 - National Acad Sciences
Aeolian sediment transport is observed to occur on Mars as well as other extraterrestrial
environments, generating ripples and dunes as on Earth. The search for terrestrial analogs …

Dune movement under climatic changes on the north‐eastern Tibetan Plateau as recorded by long‐term satellite observation versus ERA‐5 reanalysis

L Dörwald, F Lehmkuhl, J Walk… - Earth Surface …, 2023 - Wiley Online Library

A fully predictive model for aeolian sand transport

LC Van Rijn, G Strypsteen - Coastal Engineering, 2020 - Elsevier
This paper presents the development, calibration and verification of a fully predictive model
for wind-blown dry sand. The model is based on the modification of the well-known Bagnold …
