The analysis of major factors forming runoff and sediment transport of the small rivers
under the anthropogenic impact is presented in this article. Schematic graphics of major
hydrological factors and channel processes for small rivers on the bases of bibliographical data
are posted. Considerable increasing of sediment flow for small river watersheds are caused
mainly under the influence of landscape fragmentation, prevalence of silt soil composition, non-
uniform intensity of rainfall and economic activities. Water capacity reduction of small rivers and
their present degradation are connected with regulation of water moving by artificial reservoirs
and evaporation processes as well groundwater level regime. Analysis of major channel processes
factors of the small rivers is done and qualitative and quantitative changes under the influence of
anthropogenesis influences are revealed. Two periods of small rivers channel development are
studied: steady and transient. For these periods calcification of channel processes is done as well.
The possible ways of improvement condition of the small rivers of Moldova were analyzed.
