Sediment deposition within and around a finite patch of model vegetation over a range of channel velocity

C Liu, H Nepf - Water Resources Research, 2016 - Wiley Online Library
The interaction between flow and vegetation creates feedbacks to deposition that vary with
channel velocity. This experimental study describes how channel velocity and stem …

Predicting velocity and turbulent kinetic energy inside an emergent Phragmites australis canopy with real morphology

Y Shan, C Yan, J Liu, C Liu - Environmental Fluid Mechanics, 2023 - Springer
Natural plants have different morphologies, which may impact the velocity and turbulence
structures inside the canopy interior. Laboratory experiments investigated streamwise …

Application of Structure-from-Motion photogrammetry in laboratory flumes

JA Morgan, DJ Brogan, PA Nelson - Geomorphology, 2017 - Elsevier
Abstract Structure-from-Motion (SfM) photogrammetry has become widely used for

The impact of plants on fine sediment storage within the active channels of gravel‐bed rivers: A preliminary assessment

AM Gurnell, W Bertoldi - Hydrological Processes, 2022 - Wiley Online Library
The role of aquatic and riparian vegetation in driving morphodynamics of rivers is being
increasingly recognized across all river types. Here, we focus on gravel‐bed rivers, where …

Influence of floods, tides, and vegetation on sediment retention in Wax Lake Delta, Louisiana, USA

EA Olliver, DA Edmonds… - Journal of Geophysical …, 2020 - Wiley Online Library
Sediment is the most valuable natural resource for deltaic environments because it is
