Abstract:

© 34th IAHR Congress 2011. All rights reserved. In this paper, a stochastic model for analysis of the occurrence of bursting events and entrainment of sediment particles from the bed at the threshold of sediment motion is presented. This study focused on the modeling of turbulent bursts (i.e., the cycle of sweeps, ejections, and inward and outward interactions). From the collected experimental data, a transition probability is presented using Markov process. Using this information about bursting events, a Markov model is presented for the incipient motion of sediment particles. Validation of this model for particle motion was obtained using an image processing technique. Good agreement was found between the predicted number of entrained sediment particles and the observed numbers of particles.
