GROUNDWATER VULNERABILITY OF THE KARST - FISSURE HYDROGEOLOGICAL STRUCTURE OF SOUTH -FACING SLOPES OF THE NIZKE TATRY MTS., SLOVAKIA
Abstract:

An “intrinsic vulnerability” (according to Zwahlen et al., 2004) to any contamination in general is considered using Malík´s extension (2005) of the Kullman´s method (2000), based on the assessment of the degree the rock disruption and karstifica­tion, affecting the shape of spring discharge recession curves. It is based on the presumption that the intensity of natural con­tamination attenuation processes depends on rock disruption/karstification. The method is applied on the Mesozoic rock en­vironment of the most important hydrogeological structure in the southern slopes of the Nízke Tatry Mountains. Hydrograph analyses of groundwater depletion in the gauged or exploited springs were used for assessment of groundwater vulnerability to human and/or natural pollution. Differences in character of individual depletion hydrographs enable assessment an extent of absorption and elimination processes during the groundwa­ter penetration through the rock environment from the infiltra­tion area to the outflow in the spring or exploited source. The depletion hydrographs reflect not only the character (effect) of outflow area but reflect the effects whole infiltration and accu­mulation area. In total, 68 individual recession curves from 9 gauged springs were analysed. Obtained degrees of groundwater vulnerability are evaluated by 10 degree range of the Kullman´s vulnerability scheme, adjusted by Malík. The reached vulner­ability values are consequently applied and assigned to the lith­ological types of discharge area of gauged springs. This study also describes an existence of individual laminar and turbulent sub-regimes that occur in the karts-fissure rock environment, the type of rock disruption from open micro– to macro fissures - to karst channels and subsequent estimation of the karstifica­tion degree.
