Abstract: Turbulence generated by aquatic vegetation enhances the interfacial transfer process at the airwater interface (AWI) and sediment-water interface (SWI), thus impacting the dissolved oxygen (DO) level (Fig. 1d), a key indicator of water quality for aquatic ecosystems. This study investigated hydrodynamic flow-vegetation interactions and the resulting interfacial transfer across sediment-water-air interfaces in unidirectional vegetated flows. We explored the influence of vegetation, under different submergence ratios and plant densities, on the gas transfer mechanisms via a series of laboratory experiments with simulated rigid vegetation on a sediment bed.
