Karst Terminology — Definitions
The primary objective of this book is to study the hydrologic aspect of the problems of water circulation in the karst. Therefore, karst phenomena, and types and characteristics of karst will not be dealt with from the geologic and geomorphologic point of view. The following books or papers refer to the above problems: Zötl (1974), Milanovic (1981), Bögli (1980), LeGrand and Stringfield (1973), Sweeting (1973) and LeGrand (1983). Figure 2.1 is taken from the latter two papers and represents six general topographic categories which can be developed in the karst regions. The authors believe that these typical karst forms include all phenomena and are valid for the whole world. This division, as any other, has its advantages and disadvantages, but they are not important from the point of view of hydrology. The well-developed fissures of the karst areas, and consequently a very fast and great water sinking strongly affect the distinctive hydrologie behaviour of water in the karst terrains to be distinguished from the circulation in porous media. The possibility of surface flow is either unlikely or completely eliminated. In these considerations we should take into account the fact that apart from the bare karst (appearing in southern Yugoslavia, Dalmatia and Herzegovina) there are areas of covered karst (Slovenia and Gorski Kotar) with rich vegetation and a layer of covering soil up to 1m deep, in some places even several meters. In such situations the sinking is significantly slower, whereas all other processes of water circulation are identical to those in the bare karst.
