The power diameter-height relationship

The power diameter-height relationship relates height and diameter with a power function. Since it uses diameter at 10 cm, NOT DBH, it is active for saplings only.

Parameters

Parameter nameDescription
Power Function "a"The "a" parameter in the power function for the height-diameter relationship.
Power Function Exponent "b"The exponent, or "b" parameter, in the power function for the height-diameter relationship.

The power diam - height function is:

height = a * d10 b

where:

  • height is tree height, in m
  • a is the Power Function "a" parameter
  • b is the Power Function Exponent "b" parameter
  • d10 is diameter at 10 cm (in cm)
