Because of the flow complexity and wind power reduction, the regions near or within forests
have not been considered for wind park installation. However, because of the shortage of
good clear sites, this situation was reverted, adding new motivation to the study of the wind
flow over forested regions. The so-called k− ε model, the standard in flow modelling of

Because of the flow complexity and wind power reduction, the regions near or within forests have not been considered for wind park installation. However, because of the shortage of good clear sites, this situation was reverted, adding new motivation to the study of the wind flow over forested regions. The so-called k− ε model, the standard in flow modelling of engineering applications, has also appeared in atmospheric flow studies, circumventing the limitations of simpler approaches [1]. However, in the case of canopy flows, there are open questions on the actual performance of the k− ε compared with lower order models, and the mathematical form of the additional terms in the transport equations for the turbulence kinetic energy k and its rate of dissipation ε [2].
