The spatial and temporal changes of groundwater mineralization in the Mid Ob river basin
The investigation of the spatial and temporal changes of the upper hydrodynamic zone underwater mineralization in the south-east part of the Western Siberian Plane out off anthropogenic impact seats is carried out. The spatial underwater mineralization changes correlate with the zonal change of water flow modules as a whole. The analysis of the temporal changes reveals the homogeneity violation and/or the tendency to the underwater mineralization increase in the Ob watershed near Alexandrovskoye, and watersheds of the Parabel and Ket rivers. The main cause of revealed temporal changes in this region is global natural and natural-anthropogenic processes with non-salient impact of economical activity
