Description	Turbulent flow is investigated by POD, Wavelet analysis and quadrant analysis in order to reveal more about dynamics of the flow inside the canopy layer. The Intermittent behaviour of the flow is observed, since the intermittency factor of the quadrant events, especially a sweep and a ejection, is high. Typical scenario in the turbulence was evaluated from time-lag cross correlation of the POD expansion coefficients. We can conclude that the most often feature is the shift of the recirculation vortex core. Also, the wavelet analysis shows that the formation of the vortex is driven by upper approach air. The experiment is compared with LES. Turbulent flow is investigated by POD, Wavelet analysis and quadrant analysis in order to reveal more about dynamics of the flow inside the canopy layer.
