stem_vol_fun: Stem Volume Function.

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

Description

Acts as a switch to select the appropriate function to calculate the stem volume of a tree.

Usage

stem_vol_fun(species, dbh, ht, species_parameters)

Arguments

species	Tree species. If working with a non-default species (i.e. named "U^"), the stem_volume_fonweban function to calulate volume is adopted.
dbh	Diameter of the stem at breast height, i.e. 1.3m above the ground (cm). Depending on the method used ('roughness' or 'TMC') this can be either the arithmetic average of the dbh of all the trees in the stand, or the dbh of an individual tree.
ht	Tree height. Depending on the method used ('roughness' or 'TMC'), this can be either the mean tree in the stand, or each individual tree (m).

Value

The volume of the stem (m3).
