Abstract
Analysis of turbulent transfer inside a vegetative canopy can be realized by means of several methods. In our case, we have used principally the aerodynamic and the thoron methods. The thoron diffusivity profiles show an important distortion in the middle zone of the canopy, below the maximum of leaf area density. This distortion is associated with a maximum source of sensible heat flux at these levels, which partially invalidates the aerodynamic approach.
