An important component in the development of the environment is diverse and functioning public infrastructure (PI), which is managed by different sectors in Slovenia. Information on the PI in ...Slovenia is collected in the Consolidated Cadastre of PI maintained by the Surveying and Mapping Authority of Republic of Slovenia; it is an indispensable actor in the various processes of spatial governance. In this paper, a three-stage methodology for the analysis of public infrastructure is presented, which enables the systematic and repeatable analysis of PI and is also useful to check interactions between elements of PI in the observed area. The proposed methodology is tested in the wider area of the Vogršček reservoir in the Vipava Valley. Through legislation, regulations on the management and maintenance, concession contracts and agreements, the management and maintenance of PI at the intersections of different infrastructure is defined. The examples given show the importance of the optimal operation of each part of infrastructure for the operation of the infrastructure in other sectors, as well as the importance of accurate records. Suggestions for improving the situation in the field of PI records are also given.
Climate change impacts on hydrologic regime of the Vogršček accumulation (Vipava valley) were studied for a decade period 1995-2004. During this time water capture from the accumulation has been ...increased. Although a pumping did not influence the accumulationlevel a lot, it oscillated much different during single halves of the decade. The results indicated that this could result from a decrease of effective precipitation amounts, which recharge the accumulation, from changes of their distribution, as well as from an increasedfrequency of extreme dry periods and extreme precipitation events during the second decade half.
