Abstract: The siltation slope is the slope of the upper surface of the deposited material in the storage area upstream of the constructed dam. Silting up is a complex process and the assessment, i.e. the forecast of the slope of siltation is a major issue in the practice of torrent management. This paper analyses the dependence of newly formed siltation slopes on grain size composition of sediment, from the siltations of the constructed dams in torrent streams of the Trgoviski Timok catchment basin. The analysis of the dependence of newly formed siltation slope on grain size composition of sediment was performed by the method of modeling as the basic method. Regression and correlation analyses were applied as the specific research methods. The obtained results show the high correlation between the siltation slope and grain size composition of sediment, based on which it can be concluded that the obtained model is a good base for the slope of siltation forecast in future.

Opis (srp)

Abstract: Pad zaplava je pad gornje površine nataloženog materijala u akumulacionom prostoru uzvodno od izgrađene pregrade. Formiranje zaplava je složen proces, a određivanje veličine pada zaplava predstavlja značajan problem u praksi uređenja bujičnih vodotoka. U ovom radu analizirana je zavisnost novoformiranih padova zaplava od granulometrijskog sastava nanosa, na zaplavima izgrađenih pregrada u bujičnim vodotocima sliva Trgoviškog Timoka. Analiza zavisnosti novoformiranog pada zaplava od granulometrijskog sastava nanosa urađena je metodom modeliranja, kao osnovnom metodom, a korišćena je regresiona i korelaciona analiza kao konkretna istraživačka metoda. Dobijeni rezultati pokazuju značajnu povezanost između pada zaplava i granulometrijskog sastava nanosa, na osnovu čega se može zaključiti da dobijeni model predstavlja dobru osnovu za prognozu pada zaplava.
