Assessment of the thickness of the epikarst zone from distribution of doline’s depth
Abstract:



Epikarst zone, due to its peculiar hydrogeologic features and functions, plays a fundamental role in karst morphogenesis and natural protection of groundwater in the conditions of open karst. The presence of epikarst considerably diminishes high vulnerability of groundwaters, generally characteristic for karst systems. Thickness of the epikarst zone is the most important parameter that determines buffering capacity of epikarst with regard to groundwater resources, its ability to retard and neutralize contaminants, hence – the protective role of epikarst with regard to groundwater resources.

The main problem in evaluation of epikarst during groundwater vulnerability assessment is luck of methods for its mapping in area. This paper, based on the analysis of regularities of epikarst morphogenesis, substantiates a possibility to assess variations in thickness of epikarst by distribution of depth of karst dolines.

Maps of doline depth distribution (representing thickness of epikarst) are created for main massifs of the Mountain Crimea, as well as maps of density of dolines and documented caves. Conjugate analysis of these maps from the standpoint of the epikarst concept gives important information about relationship of surface and underground karstification and serves as a basis for accounting for epikarst during groundwater vulnerability assessment in regions of open karst.
