Buried valleys of the paleo-Volga and paleo-Kama tributaries of Pliocene age differ from the main paleo-valley in greater slope, elevated floor and smaller width. In the paleoSviaga valley during the Early Akchagylian the flow was a kind of lake-river, with pronounced dynamical axis and lateral zones of stagnant water, Present large water reservoirs resemble these paleo-valleys to a certain extent.
