ABSTRACT

In accordance with the Slovenian Water Act, the Government of the Republic of Slovenia determines by the Decree individual inland waters or their sections where navigation with the use of motor vessels is permitted, taking into account enabling the general use of water, their protection against pollution and the preservation of the natural balance in the aquatic and riparian ecosystems. Currently, nine Decrees on the use of motor vessels in the river sections are in force in Slovenia. In order to determine the navigation regime in the reservoir of the Brežice Hydropower Plant on the Sava River, a study was made in which the environmental basis from the river basin management plan and bathymetry of the reservoir were taken into account. The indirect and direct impacts of possible pressures due to navigation, on the ecological and chemical status of the water were analyzed. The result of the study is a designated section of reservoir where the navigation with the use of motor vessels is permitted.
