Abstrakt     Human influences on running water in the Slovenian alpine region are the reasons for treating and determination of Ecologically Acceptable Flow (EAF) for every section of the running water separately. EAF provision requires definition of the quantity and quality of water, which is needed to preserve the ecological balance in the running water and in the riparian zone. This means preservation of the structure and the function of the ecosystem, which it is reflected in diversity of species.On the basis of hydrological, morphological and ecological criteria, hydrological and ecological methods in Slovenia are applied for the determination of EAF. Hydrological method is rapid to apply, but require hydrological data, an inventory of habitats, and ecological and morphological estimation. The application of ecological method demands the sampling of zoobenthos and periphyton in different habitats of the concerned sections of running water.From 1992 more than 100 study sites in alpine streams and rivers have been examined for research and applications of the methods outlined above. This paper describes the criteria and methods used to determine EAF and experiences with their application in Slovenian alpine streams, with emphasize to the case study in the Soča River.
