Abstract: Una River is one of the few tufa-forming water streams on the territory of Bosnia and Herzegovina which are limestone formations last very long period of geological origin. The rare and unique, travertine deposits represented one of the basic elements of the natural heritage for the protection of the Una river and for the establishment of the eponymous national park. Accordingly, during 2016 were carried out field research that aimed to determine the current status of tufa deposits as well as to analyze the basic physical-chemical parameters influencing the process of formation of travertine. The studies were conducted with the help of the adequate field of laboratory equipment for physical-chemical analysis of water on more representative field locations on the river Una. The paper also analyzed microphythic and macrophyte communities that affect the process of the formation of biogenic travertine deposits. For the purpose of presenting the spatial distribution and includes travertine deposits in the study, the results of the established inventory for the same application of geographic information system. In addition to geovizual level cadastral activities are defined and accompanying geodatabase containing the basic hydro-morphological, physical, chemical and biological indicators of tufa deposits in the study sites. The results of the work are shown that the dominant type of travertine deposits represent biogenic travertine that develops in certain segments along the river Una, particularly in the area upstream from the town of Bihac. Research has also established that the basic hydrological and physical-chemical parameters of water in acceptable ecological values and favor the further development of natural travertine deposits.
