Secondary title:	Quality of river Krka in middle stream
Secondary abstract:	Since beginning of the mankind people tend to settle near rivers. The rivers represent source of drinkable water, possibility for farming, industry and other branches. Overall the rivers are ideal solution to eliminate waste waters. Rivers have the ability to decompose organic material to anorganic with the help of microorganisms. We call this self-cleaning river ability. Rough measurement for self-cleaning river ability is biochemical oxygen demand, which is increased by organic pollution. Through time the burden of pollution has overcome the river self-cleaning ability. With that observation noticed, the states began to enforce laws, to reduce, to clean and to control quality of waste water. Among significant methods for observation of water quality is waste water monitoring. Monitoring has to be carried out to find out pollution level, ecological circumstances and health influence on humans. The most important factors, which have influence to quality of water, are the number of users, the way of their living, industry, farming and outflows from larger roads. Shortly I presented QUAL2K program and have simulated the course of pollution on river Krka. I've set Concentration of certain pollutants by using the mean values and compared them with the results of monitoring and simulation results QUAL2K. I have focused on the problem of waste water disposal from larger polluters in the area. At the outflows of pollutants and in the Srebrniče settlement ARSO performs monitoring. The results were collected and analyzed for the settlement of Srebrniče.

Abstract (ePrints):	Že od pradavnine se ljudstva naseljujejo ob rekah. Reke predstavljajo vir pitne vode, omogočajo razvoj kmetijstva, industrije in ostalih panog. Ne nazadnje pa predstavljajo tudi idealno rešitev za izpust odpadne vode v njih. Reke so sposobne s pomočjo mikroorganizmov v vodi razgraditi organsko maso v anorgansko. To imenujemo samočistilna sposobnost rek. Skozi čas so obremenitve začele presegati samočistilno sposobnost vodotokov. Iz tega razloga so države začele izvajati razne instrumente in zakone za zmanjšanje, čiščenje in kontroliranje kakovosti odpadnih voda. Najpomembnejši faktorji, ki vplivajo na kvaliteto voda, so število priključenih prebivalcev na kanalizacijo, način njihovega življenja, industrija, kmetijske dejavnosti in odtoki iz obsežnejših prometnih površin ter kontrolirano izpuščanje in čiščenje teh onesnaženih voda. V diplomski nalogi sem opisal sestavo odpadnih voda po posameznih panogah. Osredotočil sem se na problem izpustov odpadnih voda večjih onesnaževalcev v obravnavanem območju. Na iztokih vseh polutantov in v kraju Srebrniče ARSO izvaja monitoring. ARSO je bil tudi vir za potrebne podatke in analizo rezultatov za kraj Srebrniče. Na kratko je predstavljen program QUAL2K in na njem simuliran potek onesnaženja reke Krke med krajema Dvor in Srebrniče. Koncentracijo nekaterih onesnažil (BPK5, dušik, fosfor, …) sem določil tudi računsko s pomočjo srednjih vrednosti odtoka padavinske vode iz prispevnih površin in jih primerjal z rezultati monitoringa in rezultati simulacije QUAL2k. Nazadnje pa sem določil še masno bilanco teh onesnažil v kraju Srebrniče, pridobljene z monitoringom, simulacijo in izračunom, vrednosti pa primerjal med sabo.
