The paper reports on modelling of air flow over the forested area of Osterild in Denmark using two different CFD models with a consistent two-equation closure. Being consistent with the canonical flow regimes of grid turbulence and wall-bounded flow, the closure used is also valid for homogeneous shear flows commonly observed inside tall vegetative canopies. The numerical experiments show that the treatment of plant drag in the closure has universality and can be applied on any two-equation closure. Results derived by different CFD models with k-epsilon and k-omega closure are similar and in good comparison with observations. Overall, numerical results show that the closure performs well, opening new possibilities for application to tasks related to the atmospheric boundary layer - where it is important to adequately account for the influence of vegetation.
