In the bed the pressure fluctuations decay exponentially within the first 1-2 equivalent sand roughnesses. Structural findings concerning coherent flow structures are consistent with models originally developed for smooth walls. A significant bed destabilizing flow-pressure pattern was identified for the first time.open channel flowpressure sensorscoherent structuresgravel bedPIVDetert Martinauth1318415BOOK9910346933603321Hydrodynamic processes at the water-sediment interface of streambeds3033215UNINA
