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 ...
Seismic hydrodynamic load analysis / Proračun seizmičkih hidrodinamičkih opterećenja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
Zangar's method for computation of seismic hydrodynamic loads acting at the inclined contour of a concrete gravity dam, has been reconsidered. Several numerical models are compared with the procedure recommended by Zangar, ...
Energy loss in a circular-conduit bends with supercritical flow / Gubitak energije u krivini kružnog provodnika pri burnom tečenju
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2013)
In this paper the energy loss in a circular conduit bend with supercritical flow is analyzed. Based on the test results obtained by a scale model, the energy-loss coefficient has been determined. Simple empirical relationships ...
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 ...
Roller compacted concrete (RCC) in dam construction, Part four: Construction, quality control and economic issues / Primena valjanog betona u izgradnji brana, IV deo - građenje, kontrola kvaliteta i ekonomski aspekti
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
The last of the four-paper serial on RCC dams refers to construction, quality-control and economic issues. The first part deals with the most important construction features, such as: concrete preparation, transportation, ...
Hydraulic design of morning glory spillway with a deflector upstream of the vertical bend / Određivanje dimenzija šahtnog preliva empirijskim jednačinama
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
Hydraulic design of shaft spillways (morning-glory spillways) with flow deflector before the vertical bend is considered. Based on the physical hydraulic model investigations of several structures and available experience ...
Contracting-expanding chute numerical modelling / Numeričko modeliranje brzotoka pri promeni pravca zida kanala
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
Two-dimensional (2D) open-channel flow models for contracting and expanding chutes are developed. TVD McCormack and TVD MUSCL method have been used to facilitate an easy-to-use code. The performances of the numerical models ...
Stresses in the upstream cutoff zone of concrete gravity dams / Naponsko stanje u zoni uzvodnog zuba gravitacione betonske brane
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Upstream cutoff in the concrete gravity dam foundation is introduced as a general stability measure in the beginning of the 20-th century. It become widely accepted in design practice in the late 50-ties. Nevertheless, ...
Numerical modeling of a steep chute with curvature in plane / Numeričko modeliranje brzotoka u krivini
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
Two-dimensional (2D) open-channel flow models for a steep chute with curvature in plane are developed. TVD McCormack and TVD MUSCL method have been used to facilitate an easy-to-use code. The performances of the numerical ...
Estimating the capacity of double side-channel spillways / Procena propusne moći dvostrukog bočnog preliva
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
A double side-channel spillway consists of two spillways, with channels joining into a common single branch, noting that for some specific site conditions such arrangements may suit better than the conventional one-side-channel ...
