lambdacapital_fun: Lambda Capital Function.

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

Description

Calculates the frontal area of the streamlined canopy per ground area.

Usage

lambdacapital_fun(
  cr_width,
  cr_depth,
  spacing,
  uguess,
  n_drag,
  c_drag,
  drag_upper_limit
)

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

lambdacapital, the frontal area of the streamlined crown under per ground area.
