A large-eddy simulation over a fully submerged, rigid canopy in an open-channel flow under transitional canopy flow regime has been carried out. The simulations revealed a flow structure characterized by the emergence of coherent structures, which are very elongated in the streamwise direction occupying a large portion of the flow inside and outside the canopy. These very large structures have a strong impact on the flow inside the canopy as well.
