the region before the final rise is attained. However, models usually apply the final effective stack height at the point above the source to simplify calculations.

An early equation to predict plume rise was developed by Holland (1953) for the Atomic Energy Commission. This equation accounted for momentum and buoyancy by having a separate term for each. A major problem with the equation was that it did not account for meteorological effects. At the time of his work, Holland recognized that the formula was appropriate only for class D stability conditions.
