Description :
This paper addresses the recent trend in fluvial geomorphology towards using computational fluid dynamics to explore the adjustment between flow processes, sediment transport and river channel morphology. It aims to evaluate the extent to which 3D models improve predictive ability and prediction utility compared to 2D applications. This is achieved through comparing the predictions of both 3D and 2D models with high-quality field data. Identical boundary conditions, obtained from a confluence within a gravel-bed river system with high relative roughness, are defined for each model.
