Summary: The cognitions of karst groundwater flow becomes ever more greater. It is based on new data about the hydrogeology of explored areas, about the groundwater flow tracing,on the cognitions about the influence of present relief on the rock permeability etc. The results indicate that the division of water management within the Adriatic drainage basin on the basis of surface water divides becomes ever more less suitable for actual needs. It is recommended a new division of the Adriatic drainage basin into hydrogeological drainage areas for which the erosion bases are their hydrogeological barriers or the sea level. It would be a new, scientific approach to the subdivision of the Adriatic drainage basin, by which a more reliable control of the protection of surface and, particularly, shallow ground drinking water would be enabled. It would also help to a most rational control of water quality in the catchment areas of drinking water pumping sites. It will also make possible a critical analysis of the purpose of the present water gauging network within the Adriatic drainage basin.

Keywords: karst, karst hydrogeology, protection of karst water

Research goals: The water management of the Republic is divided in accordance with orographic (surface) drainage areas. From a regional point of view, it refers to the Black Sea and Adriatic drainage basins; in a more detailed division, it refers to the river drainage areas. The protection of karst water, in addition to the already known problems concerning the water budgeting in karst terrains, points ever more serious to defects in the actual division of the Adriatic drainage basin. A more thorough study of karst terrains points out the possibility of analysis of karst drainage areas associating water outflows with erosional bases consisting of hydrogeological barriers or the sea. Such approach to the zoning of the Adriatic drainage basin or any other karstic terrain in the world (according to available data) has not yet been made, thus, its advantages not yet evaluated. The division of terrains by means of their erosional bases will make possible a considerably better water budget estimates and, especially, karst water protection. The research work being performed within this project will serve to the researchers for their one master of science and two doctor of science theses.
