Abstract

Runoff estimation of drainage basin s different spatial structural parts is presented in the research. The hydrological role of runoff-forming complexes is considered by the case study of the northern macroslope of the Western Sayan Mountains. The aggregate database of vegetation, soil and slope characteristics (hydrological parameters for modelling) was received during of investigated region s analysis. The base s applicability is justified by high results of calculated and obtained daily water discharge hydrographs convergence. An effect of different forest types characteristics (species composition, tree crown cover, slope steepness, soil, vegetation and other) in the runoff forming was quantitative confirmed. Water discharge is mainly provided by taiga geosystems which are prevail in water catchment areas investigated. According to the assessment of drainage basin different parts contribution to runoff the largest runoff modules and rates per unit of area are observed in nival geosystems and mountain tundras. Inconsistency of the runoff modules changing with altitude related to features of snow storage in the upper mountain levels of the Sayan Mountains northern macroslope was revealed.
