Althoughextreme hydrological events are frequently the subject of scientific research,there remains a significant information deficit regarding their direct impacton the quality of raw surface water, which is the primary source of water forpublic water supply systems. The research conducted in this dissertationfocuses on developing a model for sustainable management of waterresources during extreme hydrological events. The study was carried outusing examples from two public utility sources: "Vodovod" from Vlasotinceand "Naissus" from Niš, over the observed period from January 2014 toDecember 2018. To identify, systematize, and determine priorities forexecuting functions within the system for managing primary ecosystemservices, particularly in the context of public water supply, a methodologyof process functions combined with ranking techniques was applied. Thisapproach enabled the quantification and assessment of the effectiveness ofbusiness operations while simultaneously identifying specific processfunctions that required further improvements. For assessing the impact ofextreme hydrological events on the quality of raw surface water, statisticalanalyses were used, including: descriptive statistics, one-way analysis ofvariance (ANOVA), correlation analysis of trends, cluster analysis, andprincipal components analysis (PCA). These analyses facilitated thecharacterization, quantification, and visualization of the impacts of extremehydrological events on raw surface water quality. These analyses allowedfor the quantification of the dependencies between volumetric flows andraw water quality parameters, including turbidity, COD (KMnO4),ammonia, nitrates, nitrites, iron, manganese, pH value, BOD5, aluminumand colour. The analyses were conducted using statistical programs R 4.0.4and SPSS, characterizing changes in raw surface water quality due to flowvariations associated with extreme hydrological events. The results of theresearch have been used to develop a contemporary, sustainable waterresource management model that includes a predictive component enablingthe anticipation of potential changes in the quality and availability of rawwater. This contributes to the application of appropriate drinking watertreatment technology and facilitates timely action during extremehydrological events.
