Sharapov R. Indicators for karst processes evaluation // 14 International multidisciplinary scientific Geoconference SGEM2014. Science and Technologies in Geology, Exploration and Mining. Conference proceedings. 17-26 June 2014, Albena, Bulgaria, 2014. P. 519-525.

Karst processes have a significant impact on the safety of civil and industrial facilities. Actual tasks are objective assessment of karst hazard of a particular territory and reducing to a minimum the probability of catastrophes on newly constructed buildings caused by the development of karst processes. The paper presents a system of indicators used for monitoring and evaluation of karst processes. It details the quantitative indicators of the surface forms of karst processes, undersurface karst processes and underground hydrology displays. The indicators characterizing the surface forms of karst processes include the following: karst area infestation rate, karst form intensity rate, average frequency of karst formation, areal rate of karst area infestation, the average annual rate of karst area infestation, the volumetric rate of karst infestation, karst formation volume factor, an average annual expansion of karst area, the depth and the diameter of specific karst forms, indicator of the sinkholes depth, the rate of karst expansion size. The indicators characterizing the underground forms of karst processes are: the linear coefficient of internal karst formation, the linear coefficient of external karst formation, the linear coefficient of the total karst formation, the linear coefficient of surface karst formation, the abnormality coefficient, the linear density of karst cavities, the areal density of karst cavities, the volume density of karst cavities, karst processes activity rate, the total deposition of study area, the dissolution layer rate. The indicators characterizing the hydrological regime of the area involve the groundwater level, the rate of groundwater flow, the groundwater temperature, the chemical composition of groundwater, filtration rate of groundwater, fluctuations rate of karst springs flow rate, underground karst denudation, water saturation deficit of calcium sulfate, fluctuation rate of karst water mineralization, activity production of calcium and sulfate, calcium and carbonate, the leaching gradient.
