The VENFOR project: response of a homogeneous forest canopy to wind stress through the analysis of accelerometer measurements

Abstract : An experiment was performed in a homogeneous pine forest canopy in order to analyze the interactions between wind velocity and tree motion. Turbulence measurements were associated with two-dimensional measurements of tree motion. After a description of the experiment the simultaneous diurnal variations in wind velocity above and under the canopy are analyzed and related to stability conditions. The tree transfer function is then calculated, showing natural tree oscillation with a period of 5 s. A time-frequency analysis of tree motion is performed, showing that the tree oscillation is linked to the momentum flux.
