Assessment and analysis of the annual, low-water and minimal monthly runoff of the European part of Russia over the past 35 years (till 2011) in comparison with the earlier periods of observation (1945–1977) have been performed. The runoff genesis for different river basins has been studied and the main causes of the current changes of the runoff characteristics have been found. Regional regularities of hydrological/hydro/geological processes have been stated zoning of the territories with emphasis on the river runoff formation features has been carried out. Re-estimation of the renewable (natural) surface and ground water resources over 1970–2010 has been done. Regional estimation and analysis of water resources distribution in the European part of Russia enable to make conclusions on the surface and ground water components of river runoff spatial/temporal dynamics taking into consideration contemporary features of their formation under the non-stationary climate influence. Positive changes of the annual average and especially winter air temperatures in combination with atmospheric precipitation greatly affected the rivers water content and their runoff regime. Climate changes have already caused considerable alterations of the water regime and the water resources formation conditions in a number of major regions.
