| Abstract | Definition of karst spring catchment or basin area and boundaries belongs to one of the greatest problems of karst hydrology and hydrogeology, not adequately solved until now. This paper tries to address main problems in defining this crucial parameter. The theoretical aspect of this issue is discussed in the first two chapters. We have presented the example of the catchment area and boundaries definition for the karst spring Žrnovnica catchment in Dinaric karst. Topographic catchment area of the Žrnovnica Spring is 8.4 km$^{2}$. The significant discrepancy in size of the hydrological–hydrogeological and topographical catchment is very common characteristic for the springs located in the karst areas. In the case of the Žrnovnica Spring, the hydrogeological catchment is at least seven times larger than topographic. Two following simple hydrological methods are used in order to calculate its hydrologic–hydrogeologic catchment: (1) the relationship between mean annual discharges and annual rainfall falling on the catchment, and (2) the Turc method. It is estimated that hydrogeologic catchment area of the Žrnovnica karst spring is much larger and very probably ranges between 60 and 80 km$^{2}$. These values represent first rough assessment, which should be confirmed by more detailed interdisciplinary investigations. According to the performed tracing tests, it seems that the catchment spreads on the north-east from the topographic catchment and that the Žrnovnica Spring karst aquifer is fed by groundwater overflow from the neighbouring more abundant karts spring Jadro. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
