摘要

Results received recently in small experimental catchment are as follows: subsurface flow is prevalent over the major part of area and more frequent in time, active source area of watershed is very changeable affecting from antecedent soil moisture, surface flow origins above the soil cover mainly by heavy rainfalls, soil water residence time changes stochastically. Predictive ability of the model for infiltration based upon modified Green-Ampt approach was enhanced through a spatially common soil properties described as the joint probability function.
