|Abstract:||In order to explain the bed-load transport process by water flow, stochasticmodel is one of the useful methods which can describe the behavior of individualparticle of alluvial system.Most of the studies of bed-load thansport process by stochastic model has beencarried out only for the steady-uniform flow. But, the effect of flow unsteadiness onbed-load transport process should be considered in some real alluvial systems. Inthis study, stochastic model of the bed load transport process in unsteady butuniform flow characterized by oscillation-current coexitsing flow is proposed. Andthen, applicability of the present model is investigated by experimental results ofbed load behavior. Agreement of computed result with experiment is fairly good, and thus the unsteady uniform alluvial system can be described with the aid of thepresent model.|
