Процена криве протока у кориту за велику воду применом метода размене количине кретања и независних сегмената / Application of EDM and ISM methods in estimation of stage- discharge curve in a compound-channel
(Univerzitet u Beogradu – Građevinski fakultet, 2015)
Овај рад се бави проблемима процене криве протока у кориту за велику воду (КВВ). Истраживања течења у КВВ током протеклих 25 година показала су да традиционалне методе не дају добру процену протока и да за те поребе треба ...
Flood flow frequency analysis in the presence of outliers / Statistička analiza velikih voda u prisustvu izuzetaka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
Flood flow frequency analysis is performed on the series of hydrological observations. The observations introduce uncertainties in the analysis results, inherited from limited data sets, operational difficulties in high ...
Numerical modelling of supercritical flow in circular conduit bends using SPH method
(China Ocean Press, 2017)
The capability of the smoothed-particle hydrodynamics (SPH) method to model supercritical flow in circular pipe bends is considered. The standard SPH method, which makes use of dynamic boundary particles (DBP), ...
Effects of bed material grain-size distribution on bed morphology at a river confluence - numerical study
(EGU (European Geophysical Union), 2017)
River confluences play an important role in the drainage of a catchment and transport of sediments and pollutants within this area. Riverbed morphology at these important nodes of the river drainage network might be very ...
Enhanced DEM-based flow path delineation methods for urban flood modelling
(IWA Publishing, 2013)
In order to simulate surface runoff and flooding, one-dimensional (1D) overland flow networks can be automatically delineated using digital elevation models (DEM). The resulting network comprises flow paths and terrain ...
Хидродинамички утицаји на евакуационе објекте хидротехничких грађевина
(Универзитет у Београду, Грађевински факултет, 2018)
У оквиру докторске дисертације су анализирани хидродинамички утицаји на зидове и дно умирујућег базена иза степенастог брзотока гравитационих бетонских брана. На физичком моделу је испитан утицај геометријских карактеристика ...
Primenljivost mjesečnih bilansnih hidroloških modela u promenljivim klimatskim uslovima
(Vodoprivreda, 2020)
Mjesečni bilansni hidrološki modeli (MBHM) se često koriste u studijama uticaja klimatskih promjena na vodne resurse. Stoga bi ovi modeli trebalo da daju pouzdane rezultate u promjenljivim klimatskim uslovima. Pouzdanost ...
Effect of bed elevation discordance on momentum-flux from tributary flow and parameter values in 1d confluence models / Uticaj podvodnih kaskada na raspored protoka količine kretanja na ušću i vrednosti parametara u linijskim modelima ušća
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
Bathymetric surveys in confluences of both alluvial and mountaneous rivers have shown that a bed step at a tributary entrance to the confluence is a common morphological feature and that it may also develop in the main-river. ...
Numerical simulation of 3D flow in right-angled confluences with bed elevation discordance in both converging channels
(Elsevier, 2016)
The paper studies a combined effect of bed steps (BS) in both converging channels on the 3D flow in a confluence with α = 90o. Nine combinations of bed elevation discordance ratio values in the two channels are analysed. ...
Subsidence due to lowering groundwater level / Sleganje kao posledica sniženja nivoa podzemne vode
(Savez građevinskih inženjera Srbije, Beograd, 2014)
Subsidence due to lowering groundwater level, is often neglected problem. Detailed description of the problem is presented in the paper and model for calculating subsidence is elaborated. Model calculates vertical one ...
