Abstract: The Divergence Free Synthetic Eddy Method (DFSEM) is explored for providing turbulent inflow boundary conditions to a Large Eddy Simulation (LES) of a T-shaped confluence of open-channels. The influence of the Reynolds stress values imposed at the domain inlets onto the quality of the predicted flow is assessed. Though the impact is significant upstream of the junction, it is small downstream, where the flow characteristics are dominated by the shear layers originating from the sharp junction edges.
