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 indivi...
