| Abstract: | The purpose of this paper is to propose a mathematical method, based on forest hydrology, soil physics and soil water dynamics, for modelling forestry soil moisture change in the perpendicular profile, An IBM 386 computer w as used to investigate the soil moisture chang in addition to the processes of infiltration, surface flow and water redistribution. Determination of hydologic properties of soil water are based on the in-situ measuring of water redistribution with a double-ring infiltrometer and multriple depth tensiometers |
