Abstract:	Reke in vodotoki so že od nekdaj človeku predstavljali najdostopnejši primarni vir tako za pitno vodo kot tudi za energijo in razvoj civilizacij. S tehnološkim napredkom smo reke začeli izkoriščati in jih uporabljati tako za transportne sisteme kot za pridobivanje energije. Pri tem smo pozabili na posledice ki se kažejo v onesnaževalcih, ki vstopajo v reko in se po njej razširjajo ter vplivajo na vodni in obrežni ekosistem. Glede na vrsto onesnažila in onesnaženja lahko ukrepamo in s pomočjo scenarijev ekološko katastrofo tudi preprečimo. Reka Drava je v Sloveniji ena izmed vodilnih glede na pridobivanje energije iz vode in uporabi za vsakdanje življenje, zato bi kakršnokoli onesnaženje na reko pustilo bistvene posledice. S pomočjo programa WASP in dostopnih podatkov je tako bilo izvedeno modeliranje kakovosti vode za reko Dravo na podlagi katerega sta se ustvarila dva scenarija. Koncentracija raztopljenega kisika pri merjenju kakovosti vode reke Drave se je tako v obeh scenarijih znižala. V odvisnosti od časa in razdalje na kateri smo meritve izvajali, lahko rečemo, da je reka Drava bila najbolj obremenjena na prvi točki merjenja pri Mariborskem otoku, kjer je bila koncentracija onesnaženja največja, in najmanj obremenjena na merilnem mestu pri Starem mostu v Mariboru , ki je od izvora onesnaženja oddaljeno približno 3,2 kilometra. Velik vpliv na koncentracijo raztopljenega kisika v reki je tako imela temperatura reke Drave, saj se z višanjem temperature koncentracija raztopljenega kisika niža, kar je bilo razvidno tudi iz rezultatov.

Title:	Transport of pollutants in rivers
Abstract:	Rivers and watercourses have always been the most basic primary source for both drinking water and energy in the development of civilizations. With technological advancement, we started to exploit the rivers and used them both for transport systems and for the production of energy. In doing so, we have forgotten the consequences that occur in pollutants entering the river and spreading beyond the river and affecting the aquatic and riparian ecosystems. Depending on the type of pollutants and a type of pollution we can take action through scenarios, we also prevent ecological catastrophe. The Drava River is one of the leaders in Slovenia in terms of generating energy from the water and use for everyday life, and any pollution on the river would have significant consequences. Using the WASP program and the available data, the water quality modeling for the Drava River was carried out, which led to the creation of scenarios. The concentration of dissolved oxygen in the measurement of the water quality of the Drava River decreased in both scenarios. Depending on the time and distance at which we performed the measurements, we can say that the Drava River was the most heavily burdened on the first point of measurement at the Maribor island, where the concentration of pollution was the largest and the least burdened at the measuring point at the Old Bridge in Maribor, which is about 3.2 kilometers from the source of pollution. The temperature of the dissolved oxygen in the river was also greatly influenced by the temperature of the Drava River, so the dissolved oxygen was lowered by increasing the temperature, which was also evident from the results in scenarios.
Keywords:	River Drava, river, river pollution, pollutions in rivers, transport of pollutants in rivers modeling, transport of pollutants in rivers, WASP, water quality.
