bending_moment_rou: Bending moment on a tree under wind loading

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

Description

Calculates the bending moment on a tree resulting from the load applied by the wind.

Usage

bending_moment_rou(
  dbh,
  ht,
  cr_width,
  cr_depth,
  spacing,
  dist_edge,
  gap_size,
  uguess,
  n_drag,
  c_drag,
  drag_upper_limit,
  ro,
  fgr_constants
)

Arguments

dbh	Arithmetic average of the diameter of the stem at breast height, i.e. 1.3m above the ground, for all trees in the stand (cm).
ht	Mean tree height in the stand (m).
cr_width	Width of the tree crown (m).
cr_depth	Depth of the tree crown (m).
spacing	Mean distance between trees (m).
dist_edge	Distance of the the tree from the upwind edge (m).
gap_size	Length of the upwind gap (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

Applied bending moment resulting from the wind load (N).
