Human impact erosion and alluviation within small drainage basins of the Vyatka-Kama region

Abstract

Small rivers prevail in the drainage network and control the state of environments within the region to a considerable degree. The authors' studies over the Udmurtian territory revealed silting of small rivers channels and floodplains which resulted from violation of natural course of fluvial erosion and alluviation due to deforestation and land cultivation. The authors emphasize the necessity of the small rivers conservation which is most important ecological problem in the region.
