GIS and Hydrogeological model of Plitvice and Bihac region

During the first and second year of the project, activities of Partner No.4, together with hydrogeologists from Sarajevo (Partner No.5) were focused to collection, preparation and organization of data, which served as a background for elaborating a hydrogeological model and further modeling of intrinsic vulnerability, hazard and risk assessment of surface and groundwater resources in the area of transboundary aquifers between the Plitvice Lakes catchment area (Croatia) and Una Rriver catchment area in the Bihac region (Bosnia and Herzegovina).

All relevant data collected during the field work (1st and 2nd report period) and the results of previous studies have been incorporated into the GIS form suitable for an intrinsic vulnerability and risk modeling and assessment. At the end of the 2nd reporting period hydrogeological map scale 1:100,000 and the structuring of data base were completed. All hydogeological data (hydrographic surface network, results of tracing tests, water objects and karst morphological elements - springs, lakes, wells, swallow holes, pits etc.) were elaborated on map 1:25,000 with the amounts and accurancy of data appropriate to satisfy the scale of final map scale 1: 100,000.

Analysis and data management was performed within the Geographic Information System (GIS) with the aid of Arc/Info software (ESRI Cal. USA) and the analysis results can be visualised and modelled through the ArcMap-ArcView software. This interpretation produced important data for establishing the hazard spatial distribution and data about vegetation characteristics important for modeling an intrinsic vulnerability of waters and groundwater. During the 3rd reporting period intrinsic vulnerability and risk assessment of surface waters and groundwater were completed.

Within the whole study area, approximatelly 2752 km2 large, following thematic maps were prepared: 1. Hydrogeological map and data base, scale 1:100,000; 2. Land use map, scale1:100,000; 3. Unclassified and classified hazard maps and database, scale 1:100,000; 4. Intrinsic vulnerability map, scale 1: 100,000; 5. Risk map, scale 1:100,000.

In spite of the fact that restriction of vulnerability, hazard and risk assessment originated from the quantity and quality of data and the applied method, used approach shows many advantages for end-users:
- Formation of general base with all existing, geological, structural, morphological and hydrogeological data about surface water and groundwater resources relevant for intrinsic vulnerability assessment, distribution of different types of hazards and its potential impact - risk assessment on surface water and groundwater quality.

- Obtained maps and data bases are very useful tool for land use planning regarding the surface and ground water protection and water authorities of both countries can use such data for urgent decision making.

- The structure of data bases and layers prepared in GIS-forms allow their further application for other purposes in the future.
