drag_fun(uguess, n_drag, c_drag, drag_upper_limit)
Arguments
uguess
Critical wind speed at canopy top calculated with the roughness or single-tree method (m s-1).
n_drag
N parameter of the drag coefficient formula (dimensionless).
c_drag
C parameter of the drag coefficient formula (dimensionless).
drag_upper_limit
Maximum wind speed used during the experiments from which n_drag and c_drag were derived (m*s-1).
Value
The porosity of the crown under wind loading.
