Abstract
The article deals with analysis of precipitation-runoff relationship using hydrological balance within elementary runoff area of forest watershed in the Orlické hory Mts. The variables of hydrological balance are related to amounts of throughfall; the study deals with their relationships. A method by Kněžek was verified to separate components of runoff. We confirmed a regulation function of underground soil water reservoir in the rainfall-runoff process. Calculated evapotranspiraton mean value (1.65 mm per day) seems to be comparable to values under similar conditions. We proved that forest stands do not suffer from drought within the elementary runoff area (EOP) and maximal real water retention of soil is high (75 mm) which leads to minimum surface-runoff occurrence in forest. Soil water constants (hydrolimits) help us to get information on water component in soil water. Accuracy of results describing rainfall-runoff relationships using hydrological balance within EOP proves the analysis is correct.
