摘要: The study is focused on runoff formation processes at two scales: the scale of a small mountainous catchment its outlet and an experimental plot located in typical hillslope subregion. heterogeneous soil profile catchments formed by Cambisols developed granite bedrocks. surface appears rarely, subsurface flow forms dominant part hydrograph. From period 1998–2008, set 44 rainfall–runoff episodes was selected to analyse relationship using multiple regression analysis. physical parameters, initial water content came out as statistically significant parameter that controls forming process scale. more scattered. dynamic thresholds rainfall totals apparently control ratio magnitude stormflow both scales. Up threshold value, strongly depends saturation conditions. Above moisture conditions are less important. Copyright © 2010 John Wiley & Sons, Ltd.
