Sažetak: Ćehotina je po vodnom bogatstvu jedan od najznačajnijih vodotoka sjeveroistočnog dijela Crne Gore. Nastaje od vrela na planini Stožer, odakle teče pravcem jugoistok–sjeverozapad do svog ušća u Drinu. Značaj Ćehotine uslovljava obavezu utvrđivanja njenog fizičko-hemijskog statusa i kvaliteta voda, u cilju donošenja upravljačkih odluka na bazi principa održivog razvoja. Za realizaciju navedenog cilja korišćeni su rezultati fizičko-hemijskih analiza Sektora za hidrologiju i kvalitet voda Zavoda za hidrometeorologiju Crne Gore. Rezultati analiza utvrđeni su na osnovu uzoraka uzetih na profilima Glava Ćehotine–Bliškova i Gradac – nizvodno od mosta. Konstatovano je da donji dio sliva karakterišu povećane vrijednosti svih fizičko-hemijskih parametara, u odnosu na izvorište. Takav trend izražen je i kod azotnih jedinjenja i BPK5, kao nesumnjivih pokazatelja zagađenja. Rezultat toga je vrlo dobar status kvaliteta voda na Glavi Ćehotine, prostoru sa zanemarljivim antropogenim uticajima, i umjeren na profilu Gradac, gdje je prisustvo zagađivača izraženo. Prema vrijednosti specifične električne provodljivosti, veća je upotrebljivost voda za navodnjavanje u izvorišnom dijelu, gdje preovladava klasa S1, u odnosu na Gradac, sa dominantnom S2 klasom. Vrijednosti relativne aktivnosti adsorpcije natrijuma, pokazuju da vode na oba profila pripadaju klasi S1, pogodnoj za navodnjavanje gotovo svih tipova zemljišta.
Ključne riječi: rijeka Ćehotina, fizičko-hemijske karakteristike voda, kvalitet voda, pogodnost za navodnjavanje.

Abstract: The Ćehotina River is one of the most important watercourses in the north-eastern part of Montenegro in terms of water richness. It originates from a spring on Mount Stožer, from where it flows in a southeast-northwest direction to its confluence with the Drina River. The importance of the Ćehotina River obliges us to determine its physical and chemical status and water quality, in order to make management decisions based on the principles of sustainable development. The results of the physical and chemical analyzes of the Department for Hydrology and Water Quality of the Hydrometeorological Institute of Montenegro were used for realization of the stated goal. The results of the analyzes were determined based on samples taken at the profiles of Glava Ćehotine‒Bliškovo and Gradac ‒ downstream from the bridge. It was concluded that the lower part of the river basin is characterized by increased values of all physical and chemical parameters, compared to the source. Such a trend is expressed in nitrogen compounds and BOD5, as undoubted indicators of pollution. The result of this is a high status of water quality at the Glava Ćehotine, an area with negligible anthropogenic influences, and moderate one at the Gradac profile, where the presence of pollutants is pronounced. According to the value of specific electrical conductivity, the usability of water for irrigation is more suitable in the source area, where class S1 prevails, in comparison to Gradac, with the dominant class S2. The values of sodium adsorption ratio show that the water at both profiles belongs to class S1, suitable for irrigation of almost all types of soil.
Keywords: the Ćehotina River, physical and chemical characteristics of water, water quality, suitability for irrigation.
