Hydrological processes are leading in autonomous upland bogs, and this should reflect on the shape and dynamics of their surface, in the structure of landscapes. Oligotrophic moor "Staroselsky moss" (Central Forest Reserve, Tver Region) was studied in detail along a transect length of about 600 m. The leveling of the bog surface revealed a deviation from a normal hollow convex shape. Geodetic measurements on the rails network showed significant intra-seasonal and interannual changes in the level of the bog surface - differences in vertical movement in its parts reach an amplitude of 10 cm to 40 cm. Radar sounding revealed in the upper part of peat the aquifer layer with a thickness of 45-60 cm. This aquifer confirmed by the drilling data, determines the vertical dynamics of the surface and provides the discharge of water from the central part of bog. The spreading of waters is confirmed by the distribution of the water chemicals: the minimum pH, the electrical conductivity, K+, Ca+2, Mg+2, Cu, Fe, Mn is observed in the central bog parts.
