Abstract Floodplain (FP) vegetation determines the flow structures in river channels based on its shape, type, spacing and root‐soil binding capacity. The present study focuses experimental approach to understand role of FP determining patterns morphological changes channels.

ABSTRACT Vegetation patches, which naturally occur in a variety of patterns, have an impact on the flow dynamics and geometry rivers. There been prior studies vegetation but none examined differently shaped patch, i.e., circle, square rectangle, comparison these varying patch shapes from ecological point view. Hence, computational fluid (CFD) technique using FLUENT has employed present research to evaluate turbulence characteristics around emergent patches various forms open channel. The results show that shape had significant approaching flow, with circular offering highest resistance among all other configurations. Flow shedding behaviour behind was also prominent case formation large Kármán vortex street sizes up 1.5 times diameter. In downstream region reduction 25%–30% mean streamwise velocity observed for whereas 15% decrease rectangular patches. outcomes this study found stability channel are significantly influenced by shape. This reveals particularly configuration, influences dynamics, thereby enhancing habitat complexity riverine ecosystems. These findings vital developing informed river restoration management strategies support biodiversity promote resilience.
