Journal ArticleDOI
Biomechanical properties of aquatic plants and their effects on plant–flow interactions in streams and rivers
TL;DR: Analysis of biomechanical properties of aquatic plant stems of four common submerged river macrophyte species with bending, tension and cyclic loading/unloading tests and related these properties to the hydraulic habitats of the plants shows that they occur in a range from low to high flow velocities.
Journal ArticleDOI
Flow-plant interactions at a leaf scale: effects of leaf shape, serration, roughness and flexural rigidity
TL;DR: In this paper, the effects of leaf shape, serration, roughness and flexural rigidity on drag force imposed by flowing water and its time variability were experimentally studied in an open-channel flume at seven leaf Reynolds numbers ranging from 5 to 35 × 103.
Journal ArticleDOI
Turbulence Characteristics in Supercritical Open Channel Flows: Effects of Froude Number and Aspect Ratio
TL;DR: In this paper, the instantaneous streamwise and vertical flow velocities were measured in a laboratory flume over the entire width using a 2D-LDA system to determine turbulence intensities, and bed and Reynolds shear stresses.
Journal ArticleDOI
Flow–plant interactions at leaf, stem and shoot scales: drag, turbulence, and biomechanics
TL;DR: The analyses of bulk statistics, power spectral densities, transfer functions, and cross-correlations of measured velocities and drag forces revealed that flow characteristics, drag force, and plant biomechanical and morphological properties are strongly interconnected and scale-dependent.
Journal ArticleDOI
Sediment transport in high-speed flows over a fixed bed: 1. Particle dynamics
TL;DR: In this article, particle dynamics are investigated experimentally in supercritical high-speed open channel flow over a fixed planar bed of low relative roughness height simulating flows in high-gradient non-alluvial mountain streams and hydraulic structures.
