We derive a phenomenological continuum saltation model for aeolian sand transport that can serve as an eﬃcient tool for geomorphological applications.
A Continuum Saltation Model for Sand Dunes
An application of sand ﬂux relations are geomorphological problems, where they are used to calculate the erosion rate from the wind shear stress in order to predict the evolution of a free sand surface or dune.
A Continuum Saltation Model for Sand Dunes
In section VI we present a reduced “minimal model” that can easily be applied to geomorphological problems.
A Continuum Saltation Model for Sand Dunes
Finally, we simplify the model in order to arrive at a minimal model that can easily be applied to geomorphological problems.
A Continuum Saltation Model for Sand Dunes
We want to emphasize that our most important result for geomorphological applications is Eq.(46), which extends a common saturated ﬂux law by incorporating saturation transients.
