Abstract

Aquatic vegetation canopies significantly impact hydrodynamic and sediment transport in rivers and coastal environments. However, there are still gaps in understanding the vegetation-flow-sediment interaction. This study investigates near-bed flow characteristics using numerical simulations and high-resolution measurements. This research reveals the impact of canopy density on boundary layer thickness, bed shear stress and sediment transport. A new bed shear stress model for emergent and submerged vegetation is proposed. The effectiveness of existing bedload models for aquatic canopies is evaluated, providing valuable insights into their applicability. Overall, this research enhances our understanding of near-bed hydrodynamics in aquatic vegetation and sediment transport modelling.
