This study presents flow patterns and possible deposition around circular patches of vegetation using a two-dimensional numerical model. Because flow can pass through the patch, the formation of the von-Karman vortex street is delayed and its position moves further downstream as solid volume fraction (SVF) increases. The vortex downstream of the patch is formed as SVF≥0.08. When the two patches are very close to each other, a single vortex street is formed. As the distance between two patches is large, the effect of the interaction is weak and the vortex is developed behind individual patches. The possible deposition region is associated with SVF and configuration of the patches and thus it can provide the process on bed morphodynamics with vegetation.
