UNDERGROUND RELIEF OF KARST ROCKS AS AN INDICATOR OF SPATIAL DISTRIBUTION OF THE KARST FORMS
At the present stage of development of engineering karstology there was a necessity of change of paradigm of karst forecast from the reduced variant of the "practical" analysis of parameters of the surface karst forms and their formal distribution on territory on the "complete" analysis considering features of spatial distribution, morphology and parameters surface and underground karst forms arising under influence of features of the geological-hydrogeological structure of the karst massifs. Practice of the karst investigations suggests that the basic evaluation feature of the «closed» sections in low relief terrestrial manifestation can be «underground» relief (buried karst relief) – relief of karst rocks roof rather its elements: «high grounds» (slopes and peaks), linear and planar depressions, saddle between high grounds. Relief of the karst rocks roof is a reflection of the fracture array structure, differentiating the degree of permeability, localizing surface water and groundwater, which ultimately determines the intensity and localization of dissolution cavities in the formation and the sinks in the covering depositions.
