Framework for Dynamic Modelling of the Dam and Reservoir System Reduced Functionality in Adverse Operating Conditions
(MDPI, 2022)
Dam and reservoir systems (DRSs) are crucial aspects of the infrastructure necessary for reliable water resource management. Nowadays, DRSs are being increasingly affected by numerous natural and anthropogenic impacts ...
Long-term changes of annual and seasonal flows: A case of the Sava River / Dugoročne promene godišnjih i sezonskih proticaja - primer reke Save
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
This paper investigates the long-term changes in the hydrological time series. For this purpose, we use the trend analysis. The trend analysis is performed by using the standard Mann-Kendall trend test and by using the ...
Calculation of stone sill overflowing during low discharges / Proračun prelivanja kamenog praga u rečnom koritu pri malim vodama
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2010)
This paper is inspired by a stone sill designed in the channel of the Velika Morava river (near Markovački bridge, Serbia), in order to ensure water supply of the Thermal Power Plant 'Morava' during low flows, and to ...
Challenging analytical task: analysis and monitoring of arsenic species in water
(Environmental Engineering and Management Journal, 2014)
Analysis and monitoring of arsenic is still a challenging analytical task. Due to its complex behaviour (different forms of arsenic that can be present depending on pH and oxidation states of arsenic) as well as demanding ...
Problems in creating flood hazard maps / Problemi pri izradi karata ugroženosti od poplava
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
This paper deals with problems of creating flood hazard maps, considering methodology and problems of its implementation in practice. A case study, pertaining to production of flood hazard maps for municipality Čačak in ...
Stepped spillway flow: Comparison of numerical and scale models / Strujanje u stepenastom brzotoku - poređenje rezultata fizičkog i numeričkog modela
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
This paper deals with flow modelling of the stepped spillway for the Bogovina dam. The analysis was conducted using three approaches: scalemodelling, empirical equations and numerical modelling. An acceptable agreement was ...
Uncertainty of infrastructure leakage index (ILI) / O neodređenosti infrastruktuknog indeksa gubitaka - ILI
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2014)
In many water systems, especially in developing countries, data on the elements of the system, flow measurements and water consumption have great uncertainty. This uncertainty in the further calculations is propagated to ...
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 ...
Water distribution system model calibration using genetic algorithm / Kalibracija matematičkih modela vodovodnih sistema primenom genetskog algoritma
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2008)
Model calibration is an important step in the modelling of water distribution systems. Since calibration is a process of adjusting model parameters so that model results fit best the measured data, it becomes a complex ...
