SPATIAL-TEMPORAL ASPECTS OF THE HYDROLOGICAL REGIME IN CATCHMENTS AFTER CLEARCUTTING

This article discusses the spatial and temporal aspects of hydrological processes in catchments after logging for different landscape conditions Central Siberia. For this discussion, results our own research Sayan Mountains, Yenisei Ridge, Angara River basin, Khamar-Daban ridge literature data were involved. It analyzed impact felling area to change river flow development erosion at catchment area. The annual runoff, its seasonal structure sediment discharge significantly dependence on as clearcutting so basin. authors observations restoration water balance experimental sites small dynamics runoff large rivers. Research has shown vegetation cover changes continuously logged during post-logging forest regeneration future post-cutting hydrologic regime scenarios are determined both by further climatic succession trajectories. role time a factor decrease watershed depends many regional local features landscapes initial soil mineralized logging. forests mountainous Baikal basin model watersheds was developed.
