Since the stream-wise and vertical turbulent fluctuations have an important influence on movement of sand dust particles, accurate quantitative estimation natural wind has role in improving forecast level erosion storm. The high Reynolds number turbulence characteristics aeolian flow complexity sand-laden flows are main difficulties affecting accuracy prediction. In this study, velocity studied...

This work is about two ‘generation problems’ for classic Optimality Theory, chain shifts and saltations. The issues OT posed by traditional analyses of saltations have led to various embellishments the theory, typically in form novel constraint types. Reiss (2021a,b) proposes a general solution problem that relies more directly on different assumptions representations than constraints. Specific...

We present a model study of the aeolian saltation process where sediment samples are studied for size selective transport processes. The discrete element method is used to simulate particles different sizes, coupled with fluid boundary layer capture driving wind forces. Sediment identical median grain size, but systematically varying distributions were simulated investigate under various shear ...
