Numerous studies have been and are still being carried out on flows in periodic pattern channels. However, if these continue to multiply, it is because the phenomena involved are very complex and there are still a large number of poorly described points. The main objective of this work is to simulate physically the flow in periodic pattern channels. Given the complexity of these flows, scale models remain a privileged tool. We have carried out a series of experiments on several models of low and high slope macro-roughness channels. Our observations and experimental results have enabled us to propose empirical formulae for studying the flows in these channels.
