The role of energetic flow structures on the aeolian transport of sediment and plastic debris
Manousos Valyrakis, Xiao Zhao, Thomas Pähtz +1
Recently, significant progress has been made in conceptually describing the dynamic aspects of coarse particle entrainment, which has been explored experimentally for open channel…
The role of coherent airflow structures on the incipient aeolian entrainment of coarse particles
Xiao-Hu Zhao, Manousos Valyrakis, Thomas Pähtz +1
The role of coherent airflow structures capable of setting gravel-size particles in motion is studied theoretically and experimentally. Specifically, a micromechanical model based…
The physics of sediment transport initiation, cessation, and entrainment across aeolian and fluvial environments
Thomas Pähtz, Abram H. Clark, Manousos Valyrakis +1
Predicting the morphodynamics of sedimentary landscapes due to fluvial and aeolian flows requires answering the following questions: Is the flow strong enough to initiate sediment…
The Critical Role of the Boundary Layer Thickness for the Initiation of Aeolian Sediment Transport
Thomas Pähtz, Manousos Valyrakis, Xiao-Hu Zhao +1
Here, we propose a conceptual framework of Aeolian sediment transport initiation that includes the role of turbulence. Upon increasing the wind shear stress above a threshold v…
