Sažetak
The paper deals with the heterogeneity of hydrologic and hydrogeologic parameters in karst vadose zone. The karst vadose zone (water unsaturated zone, aerated zone) is generally very deep, ranging from tens to hundreds of meters. It is area of continuous and rapid groundwater level oscillations, with water circulation primarily governed by the dynamics of the karstification processes. The key to understanding and predicting groundwater flow through karst vadose zone and karst aquifer lies in our ability to accurately define the features and locations of the heterogeneities and their hydrologic and hydrogeologic parameters. Determination of these parameters through groundwater level measurements using piezometers and discharges of karst springs is stressed as particularly useful. The hydraulic conductivity, K, is a key multidisciplinary parameter necessary for understanding and modelling karst groundwater circulation. The example of definition of K for the Ombla karst spring catchment is given. Karst vadose zone and aquifer are dynamic space in which inclinations and flow directions change rapidly, depending of groundwater level in some of its parts. Correlation analyses of groundwater levels continuously measured in a few piezometers pointed to more uniform aquifer behaviour during the descending than during the rising of the outflow karst spring hydrograph.
