ABSTRACT
When the atmospheric precipitation falls through the system of forest vegetation, because of the influence of the canopy, it was assigned into intercept, through flow and stem flow (Ma, 1993). The relationship of these variables as below:
P = P′ + I + G. (1)
P means atmospheric precipitation (mm); P′ means fall through flow (mm); I means forest canopy interception (mm); G means stem flow (mm).
