Slovenian legislation regulates inland waterway transport by various regulations. The state and municipalities thus have certain responsibilities in regulating inland navigation, where problems arise. This area would urgently need to be dealt comprehensively, and in practice it is addressed individually by the Ministry of Infrastructure responsible for the Inland Waterways Navigation Act and the Ministry of the Environment and Spatial Planning responsible for the Water Act, each while local communities, in their own right, determine navigational regimes with municipal ordinances. There is also a problem in monitoring the implementation of legislation and local regulations.
As a basic starting point, the master's thesis explores historical facts of the once important navigable areas of Slovenian rivers. This is followed by a normative study of key regulations on inland navigation in the European Union (EU) and the Republic of Slovenia (RS), followed by a case study of the International Sava River Basin Commission and a study of the potential effects of loads caused by motorized vessel navigation. The master's thesis also contains an analysis of the peculiarities of the control of inland navigation and the problems of the powers of the supervisory authorities.
The results of the study confirmed the hypothesis that, by properly regulating the inland navigation area, road transport could be relieved and thus significantly contribute to the reduction of environmental pollution due to transport. The case study of the ISRBC showed that, as a member of the International Sava River Basin Commission, the Republic of Slovenia does not recognize the existing development potential for the development of navigation. The hypothesis concerning the control of inland navigation in the RS, which is deficient and inadequately regulated, was also confirmed.
Based on the established situation, radical changes in this area are needed in the Republic of Slovenia.
