Using a coupled fluiddiscrete element model, the granular stress tensor is computed locally as a function of the depth, and the results are analyzed in the framework of the µ(I) rheology. Varying the Shields number, the specific density and the particle diameter, the data are shown to collapse over a wide range of inertial number and up to unexpectedly high values (I ∼ 3). The results give a better understanding of the granular behavior in bedload transport and challenge the existing conceptions and parametrizations of the µ(I) rheology.
