Assessing entrainment of bed material in a debris-flow event: a theoretical approach incorporating Monte Carlo method
Hits:
Release time:2018-06-13 Journal:Earth Surface Processes and Landforms Abstract:Entrainment of underlying bed sediment by a debris flow can significantly increase the debris‐flow magnitude. To study this phenomenon, a theoretical approach to assessing bed‐sediment entrainment is presented. The approach is based on a static approximation that bed‐sediment entrainment occurs when the shearing stress of the flow is sufficiently high to overcome the basal resistance of the bed sediment. In order to delineate erodible zones in a channel, we analyze the critical condition of this static equilibrium model, and subsequently propose a new concept of a critical line to detect ...
