Flow Characteristics in Open Channels with a Permeable Bed
RÉSUMÉ
Turbulent flow in an open channel with a permeable bed is investigated experimentally with the use of hot-film anemometry. The permeable bed is simulated with (1) porous filters and (2) flexible vegetation of same porosity ε (0.70 and 0.91). The relative thickness of the porous layer s'/h (s' = porous thickness, h = total flow depth) varies between 0.375 and 0.500. Measurements of mean velocity and turbulence characteristics (Reynolds stresses) indicate the effect of the material used (filters, vegetation), ε, and s'/h on the flow characteristics.
