Sažetak
- KARST GROUNDWATER PROTECTION IN CROATIA AND TWO CASE STUDIES ; - CASE STUDY 1 – LIČKA JESENICA - CASE STUDY 2 – MILJACKA ; - CONCLUDING DISCUSSION: The protected area of the Jesenica springs includes the entire catchment area (110.27 km2). Nevertheless, protection of the Miljacka spring is limited only to a part of the catchment, and a significant part of the catchment in the east remains to be added after the next phase of investigation. The part of the catchment containing a portion of the inflow area is mostly built of carbonate rocks and is very permeable ; it was determined to extend up to an area of 516.46 km2. Only a part of the water collected on this huge surface actually discharges into the Miljacka. In contrast, in the west and north, there are small parts of the terrain whose credentials as belonging to the Miljacka catchment are questionable and have to be additionally researched. From the eastern part of the terrain (an arrow in the Figure 3), there is inflow of the Krka River into the karst terrain close to the Miljacka spring. In the riverbed, there are a few swallow holes noted, but these have never been traced. Although the majority of the groundwater flows from the north and the Zrmanja River, there is still the possibility that a certain percentage of the spring water originates from Krka. Therefore, the entire catchment region of the Krka River and its confluents Butišnica, Krčić, and Kosovčica, will have to be added to these proposed groundwater protection zones. All the data collected during the bulk research in the two presented case studies have been deposited in the database and processed with the ArcGIS software package, which resulted in GIS-based cartography. The main goal is to create an interface, with ArcGIS as an interactive modeling environment. Regarding the areas of Lička Jesenica and Miljacka karst springs, establishment of groundwater sanitary protection zones has been the first step toward the significant improvement in land use of these wide karst catchments.
