<p>A numerical investigation was conducted to analyze flow attributes and suspended sediment, within and around both emergent and submerged vegetation, employing a two-dimensional (2D) model. In this model, vegetation was represented as an absorbent region to consider the drag and flow resistance induced by plant structures. The simulation model was validated against experimental data obtained by Lu (Experimental study on suspended sediment distribution in flow with rigid vegetation, 2008), confirming its reliability and precision. The research examines key flow attributes and spatial distribution patterns of suspended sediments within sediment-laden vegetated flows, considering a range of hydraulic conditions. By comparing emergent and submerged vegetation scenarios, the study provides insights into how vegetation and flow regime influence sediment suspension, transport mechanisms, and associated flow structures. Furthermore, detailed analyses were performed to explore the correlations among key variables influencing suspended sediment dispersal, covering flow velocity, vorticity, and turbulent kinetic energy (TKE) fields. It was observed that the TKE field beyond the canopy demonstrated a positive relationship with sediment concentration, while near the bed; TKE field was almost associated with the spatial distribution of suspended grains. In the present study, under conditions of low flow blockage, sediment deposition in the wake zone extended over a considerable distance downstream. However, when the flow blockage was sufficiently large to generate a vortex street, improved sediment deposition was concentrated in two distinct areas: nearly downstream of the vegetation canopy and in the recirculation area. The spanwise distribution of particles is characterized using a probability density function (PDF), which reveals temporal irregularity in the particle field, quantified by the variance of the PDF.</p>
