15 equal sections formula - Opis:
- A model for volume shares of 15 stem sections of the same relative length was developed on the basis of empirical material consisting of 615 larches. The volume share for each section is described by a general equation [2] taking into consideration the diameter at breast height and height of a tree. The parameters of the equation are presented in the table. With the empirical formula for the dbh form factor of the larch stem under bark [4], the volume of a tree can be determined using formula [3]. This enables building a taper model, thus determining the thickness in the middle of each of 15 sections and, by way of linear interpolation, the thickness in any place within the stem. The model allows to calculate the volume of any part of the larch stem.
