Mixing layers and coherent structures in vegetated aquatic flows
Marco Ghisalberti,Heidi Nepf +1 more
TL;DR: In this article, the authors demonstrate that the flow structure within and just above an unconfined canopy more strongly resembles a mixing layer than a boundary layer, and demonstrate the applicability of the mixing layer analogy to aquatic systems.
Journal ArticleDOI
The structure of the shear layer in flows over rigid and flexible canopies
Marco Ghisalberti,Heidi Nepf +1 more
TL;DR: In this paper, the structure of coherent vortices and vertical transport in shallow vegetated shear flows were studied with rigid and flexible model vegetation to study coherent waving of flexible canopies.
Journal ArticleDOI
The limited growth of vegetated shear layers
Marco Ghisalberti,Heidi Nepf +1 more
TL;DR: In this paper, the authors show that the growth of obstructed shear layers is arrested once the production of shear-layer-scale turbulent kinetic energy (SKE) is balanced by dissipation of SKE within the canopy.
Journal ArticleDOI
Retention time and dispersion associated with submerged aquatic canopies
TL;DR: In this article, a two-box canopy model is proposed to predict the timescale required to flush the canopy through vertical exchange over a range of canopy density and height, which is consistent with canopy retention inferred from tracer observations in the field and comparable to retention times for some hyporheic regions.
Journal ArticleDOI
Flow and transport in channels with submerged vegetation
Heidi Nepf,Marco Ghisalberti +1 more
TL;DR: In this article, the authors reviewed recent work on flow and transport in channels with submerged vegetation, including discussions of turbulence structure, mean velocity profiles, and dispersion. And they showed that the dominant characteristic of the flow is the generation of a shear-layer at the top of the canopy.
