Organised turbulence over mobile and immobile hydraulically rough boundaries
Leal, J. B.; Ferreira, Rui M. L.; Franca, Mário J.; Cardoso, António H.33rd IAHR Congress: Water Engineering for a Sustainable Environment ; The present work is aimed at the study of near-bed organised turbulence over mobile and immobile, porous, hydraulically rough boundaries. The bed was permeable and composed of non-cohesive sediments. Two data sets were analysed, characterised by the same u*. The mobile bed data featured generalised sediment transport for all size fractions s...
Parameterization of the logarithmic layer of double-averaged streamwise velocit...
Franca, Mário J.; Ferreira, Rui M. L.; Lemmin, UlrichThe logarithmic layer of double-averaged (in time and space) streamwise velocity profiles obtained from field measurements made in the Swiss rivers, Venoge and Chamberonne is parameterized and discussed. Velocity measurements were made using a 3D Acoustic Doppler Velocity Profiler. Both riverbeds are hydraulically rough, composed of coarse gravel, with relative submergences (h/D50) of 5.25 and 5.96, respectivel...
