Abstract
In this paper impact of sewer outlets on water quality of Topciderka river has been presented. Water quality model has been developed as a joint of two standard software packages: HecRAS and QUAL2E. HecRAS, as supporting tool provided hydraulic parameters that QUAL2E used in computation of transport and chemical processes. Calibration and verification of a model were performed according to field samples collected on sewer outlets and from the river stream. As determined that the storm water sewage is used for waste water, it is suspected that the households nearby the Topciderka river were connected to the sewer illegally during past few years. According this proposition for the ecological rehabilitation of the river is presented.
U radu je prikazan uticaj kanlizacionih nepusta na kvalitet vode u Topčiderskoj reci. Kvalitet vode je modeliran kombinovanjem dva standardna programska paketa: HecRAS i QUAL2E. HecRAS je, kao pomoćni alat kojim je modelirana hidraulika vodotoka, dao hidrauličke parametre, dok je QUAL2E koji modelira hemijske i transportne procese, tj. kvalitet vode u vodotoku, te parametre koristio kao ulazne. U cilju verodostojnog interpretiranja kvaliteta vode u vodotoku modelom, kalibrisanje modela je obavljeno na osnovu kvaliteta uzoraka zahvatanih iz reke i sa nepusta. Obzirom da je utvrđeno da kroz ispuste kišne kanalizacije teče fekalna otpadna voda, glavna pretpostavka je da su se domaćinstva okolnih naselja na slivu Topčiderske reke nelegalno priključila na kišnu kanalizaciju. Na osnovu ove pretpostavke dat je predlog mera za ekološku sanaciju Topčiderske reke.
