Measurements of the water balance components of a large green roof in the greater Paris area
(Copernicus Publications, 2020)
The Blue Green Wave of Champs-sur-Marne (France) represents the largest green roof (1 ha) of the greater Paris area. The Hydrology, Meteorology and Complexity lab of École des Ponts ParisTech has chosen to convert this ...
Two Improvements to Gardner's Method of Measuring the Hydraulic Conductivity of Non‐saturated Media: Accounting for Impedance Effects and Non‐constant Imposed Suction Increment
(Wiley Open AccessAmerican Geophysical Union, 2019)
Gardner's (1956, https://doi.org/10.2136/sssaj1956.03615995002000030006x) transient method of measuring the hydraulic conductivity function of unsaturated media has been largely used, together with the improved graphical ...
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 ...
Optimization of water allocation from a multipurpose reservoir / Efekti primene pravila upravljanja pri raspodeli vode iz višenamenske akumulacije
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2008)
The ever increasing water demand in conditions of divergent variability of both natural flows and water requirements can only be met by finding new water sources, combined with the building of new water storage reservoirs. ...
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 ...
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, ...
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 ...
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 ...
