Abstract

In this paper is presented intrinsic vulnerability assessment of the aquifer in the Rižana spring chatcment by the method SINTACS. It is parametric method that takes into consideration seven parameters (depth to ground water, effective infiltration action, unsaturated zone attenuation capacity, soil/overburden attenuation capacity, hydrogeological characteristics of the aquifer, hydraulic conductivity range of aquifer, hydrologic role of the topographic slope). Parameters are presented in grid information layers that were elaborated on the basis of interpretation and GIS processing of geological, hydrogeological, speleological, topographical, meteorological and pedological data. According to the parameters importance for vulnerability assessment, a multiplier (importance weight) was assigned to each parameter. Final map of vulnerability is a result of overlaying (summing) of weighted information layers (parameters) and shows the catchment area of the Rižana spring subdivided into six vulnerability classes.
