gammasolved_fun: Gamma Solved Function.

In tom-locatelli/fgr: R Version of the ForestGALES wind risk model

Description

Calculates the ratio between the critical wind speed at canopy top and the friction velocity (uh / u*).

Usage

gammasolved_fun(
  cr_width,
  cr_depth,
  spacing,
  uguess,
  n_drag,
  c_drag,
  drag_upper_limit,
  fgr_constants
)

Arguments

cr_width	Width of the canopy in windless conditions (m).
cr_depth	Length of the canopy in windless conditions (m).
spacing	Mean distance between trees (m).
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

gammasolved, the ratio of critical wind speed at canopy top over friction velocity (uh / u*).
