Abstract
Turbulent open channel flow over a two-dimensional dune with small submergence is investigated numerically by Large Eddy Simulation (LES) and experimentally with Laser Doppler Velocimetry (LDV). Experiments are used for validating the simulations, which in turn provide an ideal complement to the experiments to investigate the flow properties with a high spatial resolution. In this paper we discuss flows over large roughness elements with low submergence by analyzing the spatially averaged profile. As expected, it is found that the roughness is affecting the flow throughout the depth, and a more substantiated roughness characterization is needed for describing these types of flows.
