Theory and new applications of structure analyses of daily hydrologic series / Teorijske osnove i proširenje oblasti primene strukturne analize dnevnih hidroloških serija
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
Structure of daily hydrologic series, based on TIPS methodology (Yevjevich, 1984), is extended and new possibilities for stochastic analyses and applications are presented. First, estimation of smoothed time functions of ...
Streamflow measurement by salinity dilution method / Merenje protoka u otvorenim tokovima metodom razblaženja koncentracije soli
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
Streamflow measurement often requires a clearly structured measurement reach. Velocity distribution can then be measured using a current meter or by constructing a hydraulic section control (weirs or flumes). However, in ...
Harmonization of development projects in the Drina river basin with environmental conservation requirements / Razvojne projekte na slivu Drine uskladiti sa zahtevima očuvanja životne sredine
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2004)
The implementation of new projects in the Drina river basin will depend on their successful harmonization with the social and ecological environment. The paper discusses the trends which govern the evaluation and approval ...
Stochastic approach to flood damage assessment / Stohastički pristup u određivanju šteta od poplava
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2008)
This article deals with deterministic and stochastic approaches to assess the expected annual flood damages. Each approach is illustrated by a case study pertaining to floods at different sections of the Tamnava river in ...
Physical methods for waste water treatment: The use of freeze/thaw method with the assistance of microwave radiation for oily water treatment / Fizičke metode za prečišćavanje otpadnih voda - primena metode naizmeničnog mržnjenja i hlađenja i mikrotalasnog zagrevanja za obradu zauljenih voda
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
The main sources of oily waste water are oil- refineries, metal industry and food industry. Any technological process that uses emulsions has to take into consideration also the treatment of the used emulsions. The ultimate ...
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. ...
Instability analysis of the air-water flow in porous medium / Analiza pojave nestabilnosti kod dvofaznog strujanja u poroznoj sredini
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
The paper deals with modeling of two phase (water-air) flow in coarse porous medium, where, after reaching some air velocity, instability of the flow occurs. Firstly, a linear stability analysis has been conducted for ...
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, ...
Field measurement of small velocities / Merenje malih brzina u terenskim uslovima
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
The application of 2D and 3D Computational Fluid Dynamics (CFD) modeling in open river flow is gaining in its popularity, especially in the field of sediment deposition on the river confluences and bay entrances. The ...
Određivanje trajektorije kamena u tekućoj vodi / Determination of a stone particle trajectory in the flowing water
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2002)
U ovom radu prikazana je metodologija proračuna trajektorije kamena u tekućoj vodi. Analizirani su faktori koji utiču na dužinu trajektorije, odnosno na vreme tonjenja i domet ispuštenog zrna. To su: početna dubina sa koje ...
