ABSTRACT
It is very difficult to define hydrogeological parameters in an anisotropic aquifer such as carbonate matrix. Even the application of many different methods cannot provide a robust case for the karst aquifer. However, in the past decade a whole new branch of karst investigation, 3D modeling of karst aquifers and karst conduits, has become widely used in the earth sciences. The main topic of this chapter is 3D reconstruction and modelling of the Beljanica karst aquifer. The input parameters of the model are represented by the 69 caves, 15 sinkholes and 1682 dolines, 7 major karst springs, around 70 minor springs, and all available geological, morphological and hydrogeological data. As output from the model, more than 6000 nodes (registered in the database) were calculated. There are in some cases 60 different numbers for each node. The 3D model of the karst conduit network, enables the reconstruction of a complex karst aquifer, including its spatial, temporal, quantitative and qualitative characteristics.
