Relaxation processes in Aeolian transport

Representation of land-surface processes in aeolian transport models

Mathematical modelling provides an essential tool for understanding aeolian transport of dust and sand, its spatial and temporal dynamics, and its role in the earth system. As much of the crucial action takes place at or just above land surfaces, adequate representation of land-surface processes is essential. In this paper, we review progress in aeolian transport modelling during last two decad...

Periodic trajectories in Aeolian sand transport

Laboratory Simulation of Aeolian Sand Transport and

This paper discusses the possibilities of laboratory simulation of large-scale flow around dunes, both with and without saltation, and the study of the physics of the small-scale particle motion occurring on a sand surface composed of like-moveable particles. Physics of the atmospheric boundary layer are presented in the context of laboratory applications. The governing equations of fluid and/o...

Ground robotic measurement of aeolian processes

Models of aeolian processes rely on accurate measurements of the rates of sediment transport by wind, and careful evaluation of the environmental controls of these processes. Existing field approaches typically require intensive, event-based experiments involving dense arrays of instruments. These devices are often cumbersome and logistically difficult to set up and maintain, especially near st...

Aeolian sand transport with collisional suspension

Aeolian transport is an important mechanism for the transport of sand on Earth and on Mars. Dust and sand storms are common occurrences on Mars and windblown sand is responsible for many of the observed surface features, such as dune fields. A better understanding of Aeolian transport could also lead to improvements in pneumatic conveying of materials to be mined for life support on the surface...
