Abstract

This paper describes ideas to incorporate the influence of turbulence into the existing sediment transport models to more realistically account for the effects of turbulent flow field. Bridge scour is a complicated process involving the interactions between flow and piers and between flow and sediments. The existing numerical studies often couple sediment transport models to a turbulence flow model to simulate the scour process. These traditional sediment transport models are often based on concept such as critical shear stress. The influence of the turbulence fluctuation and the lifting force are not considered in the traditional sediment models. In this paper, we propose a framework to incorporate the effects of turbulence into sediment transport models.
