Based on the results of long-term research, Selni{ka Dobrava water resource was estimated as an adequate source of drinking water supply for the Maribor waterworks.Further activation of the resource for its optimum exploitation and management requires the determination of suitable pumping well locations on the basis of hydrogeological properties. This paper describes the development and application of an integrated hydrogeological model for the Selniška Dobrava. Model development is considered to be an important part in the establishment of sustainable water management policies for the Selniška Dobrava- Maribor waterworks. Selni{ka Dobrava model was developed by usingthe MIKE SHE integrated modelling package. The model enables an analysis of the complex hydrogeological regime in the region and the prediction of environmental impacts of various management options. Different scenario simulations were used to evaluate pumping station location suitability and the possibility of pumping sufficient quantities of water. Results of different simulations show that the construction of a pumping station for 200 l/s and more on Selniška Dobrava is possible. The model indicates a more favourablesetting up of pumping wells in the section transversal to groundwater flow direction. Such setting up enables an easier application of water resource protection measures.
