The uplift was estimated for the past 10,000 years. Interpolation (Triangulation with Linear Interpolation, Natural Neighbor, Local Polinomial) and geostatistical (kriging) methods were used to construct the schemes if isobases of the uplift. It was determined that the most acceptable results of modeling the isobases of uplift, based on a given amount of data, were obtained using the methods Natural Neighbor and Kriging with linear drift. The schemes show the domed character of the uplift of the earth's surface. The maximum amplitude of the uplift (more than 120 meters) is noted in the southwest of the study area.
