The 3DNet-Catch hydrologic model: Development and evaluation
(Elsevier B.V., 2019)
Hydrologic models are important for effective water resources management. They vary in complexity from parsimonious, spatially lumped, to physically-based, fully distributed models, which are generally expected to outperform ...
Flood control of tailings-dam reservoirs / Problemi evakuacije velikih voda iz jalovišnih akumulacija
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
This paper analyzes the problems of flood control for the tailings-dams reservoirs, having in mind the significant rise of the flow and volume of observed flood waves, and increasingly stringent criteria for safety of high ...
Кartiranje parametra metode Langbajna za proračun srednjih voda na neizučenim slivovima na teritoriji Srbije
(Vodoprivreda, 2019)
U radu se razmatra određivanje srednjih voda na malim neizučenim slivovima u okviru teritorije Republike Srbije, na kojima ne postoje hidrološki podaci o mere-nim protocima. Razmatrana je metoda Langbajna u kojoj je ...
Computation of Thermal-Stresses and Contraction Joint Distance of RCC Dams
(Journal of Thermal Stresses, 2013)
A new approach in 3D numerical modeling for unsteady phased thermal-stress analysis of a massive concrete hydraulic structure is presented. The temperature field is computed first, providing a drive for the unsteady, ...
Hydraulic analyses of stepped spillway flow / Hidraulička analiza strujanja na stepenastom brzotoku
(Savez građevinskih inženjera Srbije, Beograd, 2014)
Stepped spillways have been often used in RCC dams over the past twenty years, due to their efficiency in converting mechanical energy into heat and compliance with the technology and construction of RCC dams. Main ...
Algorithm for water distribution network segmentation using existing isolation valves / Algoritam za segmentaciju vodovodne mreže pomoću postojećih izolacionih zatvarača
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2014)
Dividing a complex water distribution network (segmentation) on smaller zones, with defined entry and exit points, is a precondition for better water loss management. In order to obtain these zones, often called District ...
Uniformity and Heuristics-Based DeNSE Method for Sectorization of Water Distribution Networks
(Reston, VA (USA): ASCE - American Society of Civil Engineers, 2020)
Sectorization of a water distribution network (WDN) into district metered areas (DMAs) is a proven solution for proactive leakage control. Traditionally, WDN sectorization is conducted by local experts using a trial-and-error ...
Water profile computations in non-prismatic compound channels with simple cross-sectional geometry using exchange discharge model / Proračun linije nivoa u neprizmatičnom koritu za veliku vodu primenom metode razmene količine kretanja između glavnog korita i plavnih površina - primer korita jednostavne geometrije
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
The paper aims at presenting possibilities of the exchange discharge model (EDM) in 1D non-prismatic compound channel flow modelling to the Serbian hydraulic engineering community. The model has been already successfully ...
Thermal-stress behaviour of RCC gravity dams / Termičko naponsko stanje gravitacionih brana od valjanog betona
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2015)
Roller Compacted Concrete (RCC) is a special concrete mixture with low cement content, frequently used for concrete gravity dams. This paper deals with the 3D finite element model for unsteady phased thermal-stress analysis ...
Methodology for sequent depth estimation for converging stepped-chute stilling basins / Metodologija proračuna spregnutih dubina kod umirujućih bazena neprizmatičnih stepenastih brzotoka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
The influence of converging stepped spillways on the dimensions of the stilling basins for RCC dams was examined, based on the results of physical modeling, existing empirical expressions, and basic laws of fluid mechanics ...
